Cisco Packet Tracer and IPv6 Addressing...

Cisco Packet Tracer and IPv6 Addressing

Yesterday, I used Cisco Packet Tracer for the first time in several weeks.

I completed a Cisco Packet Tracer exercise from "Module 4: IPv6" in the Network Addressing and Basic Troubleshooting online class from the Cisco Networking Academy. 

The exercise involved configuring IPv6 on a router, two servers, and four computers.

The exercise was fairly simple. It involved opening the Cisco IOS on the router, activating IPv6, and then setting the IPv6 host address for the router as well as entering the IPv6 address for the default gateway.

After that, it was a simple matter of entering the IPv6 host address and the IPv6 address for the default gateway for each host (the laptop and desktop computers) and the servers.

The last step of the exercise involved running ping tests from each host to ensure that they can contact the internet service provider.

Cisco Packet Tracer and IPv6 Addressing

In Conclusion

All-in-all, the IPv6 addressing exercise was a relatively simple one to execute. Still, it's good to get the feet wet and get some experience using IPv6. For IT, IPv6 is the wave of the future. It's just a matter of time before IPv6 replaces IPv4 when it comes to addressing for computer networks. I will be working on another IPv6 addressing exercise for Cisco Packet Tracer later this morning.

New Ethernet Cable Tester...

New Ethernet Cable Tester

On Monday afternoon, I bought a Klein Tools Ethernet cable tester from a Home Depot in Peoria, AZ. Just as a disclaimer, I refer to anything in Peoria, AZ that is south of Bell Avenue as being located in "South Peoria". I live close to the isthmus that runs between Glendale, AZ and Sun City, AZ that connects "North Peoria" to "South Peoria". Yes, the city boundaries of Peoria, AZ are strange. It would make for an interesting post to investigate why.

Anyway, I bought an Ethernet cable tester because I wanted to test the Ethernet cables that I made using the T-568A and T-568B cabling standards. To put it another way, I made a straight-through cable and a crossover cable. Now, I want to test both cables to see if I did it correctly.

While making the cables, I took a series of photos with my cell phone camera.

In the coming days, I will write a post about making a straight-through cable and a crossover cable.

Stay tuned.

It Has Been a Couple of Days...

It Has Been a Couple of Days

Yes, I am completely aware that I haven't updated my blog over the past couple of days.

In fact, I left my most recent post incomplete.

Then, there are posts that I need to re-write and/or update.

Plus, there is my backlog of posts that I keep intending to write about.

If I don't update my blog, then those posts don't get written.

It's that simple.

Restarting the Pearson CCNA 200-301 Network Simulator...

Restarting the CCNA 200-301 Network Simulator

Last night, I re-acquainted myself with the Pearson CCNA 200-301 Network Simulator.

Pearson CCNA 200-301 Network Simulator

When I started studying for the CCNA certification a couple of years ago, I went ahead and bought a copy of the CCNA 200-301 Network Simulator. The CCNA 200-301 Official Cert Guide from Cisco Press came with a demonstration copy of the CCNA 200-301 Network Simulator on an included DVD. The author of the Official Cert Guide, Wendell Odom, recommended trying out the Network Simulator.

After trying out the sample exercises on my Dell laptop, I was impressed enough with the product to download my own copy from Pearson's website.

Creating Your Own Computer Networks

As you study for the CCNA certification, you will eventually want to try to make your own computer network diagram, also called a logical topology diagram, consisting of switches, routers, desktop computers, laptop computers, cell phones, printers, and so on. In addition, you will also want to try using Cisco's command line interface (CLI) program, known as the Cisco IOS, to configure all of those switches, routers, desktop and laptop computers, cell phones, and printers for your computer network. The Cisco IOS looks and feels quite similar to the Command Prompt for Windows. Creating your own logical topology diagram and then properly configuring every device on the diagram are both very important skills to know how to do.

Fortunately, there are several computer programs available that will assist you with both tasks. Just know that there are things to know about each program.

CCNA 200-301 Network Simulator

The CCNA 200-301 Network Simulator from Pearson Vue, the program that I recently re-started using, is probably the program to get if you want experience with using the Cisco IOS. Beginning with Chapter 4 of the CCNA 200-301 Official Cert Guide, you get several exercises per chapter that focus on using the Cisco IOS to accomplish various tasks. For the most part, the exercises guide you step-by-step until completion. The idea is to get the user comfortable using the Cisco IOS. There are hundreds, if not thousands, of commands for the Cisco IOS, so you might as well just jump in headfirst. With each succeeding chapter from the CCNA 200-301 Official Cert Guide, the exercises get a little longer and a little more complex. One thing that the CCNA 200-301 Network Simulator does not do is let you create your own logical topology diagrams. The program does have logical topology diagrams; however, the diagrams are to illustrate what the network looks like. You cannot make any changes to the diagram. The main focus of the Network Simulator, based on my experience, is getting comfortable using the Cisco IOS. I highly recommend buying a copy of the CCNA 200-301 Network Simulator, which will cost you approximately $100 to download from Pearson Vue.

Pearson Vue's CCNA 200-301 Network Simulator

Cisco Packet Tracer

You can also use Cisco's Packet Tracer program. Cisco Packet Tracer will let you create your own logical topology diagrams with Cisco-approved icons. With Cisco Packet Tracer, you don't have to use the Cisco IOS to configure devices. Cisco Packet Tracer will let you click on radio buttons and/or manually enter items like IPv4 or IPv6 addresses or default gateways without entering into the Cisco IOS. You can pick and choose what icons you want to have on your diagram and then choose how to connect the devices with the click of a mouse. However, if you want to manually configure a device in the Cisco IOS, you can do that to. In fact, if you configure a device without using the Cisco IOS, Cisco Packet Tracer will automatically generate the appropriate commands in the Cisco IOS. I kid you not. The idea of Cisco Packet Tracer is to replicate the experience of having phyiscal networking equipment on a computer without having to buy networking equipment. Cisco Packet Tracer was designed for users with ZERO netowrking experience. In case you didn't know, many of those home networking kits that you can buy on the internet from vendors can be quite expensive depending on the equipment and the options you want. Best of all, Cisco Packet Tracer is F-R-E-E from Cisco. Yes, Cisco doesn't charge a penny for Cisco Packet Tracer. However, you do have to register with Cisco Networking Academy to download the program. With all of the great things that Cisco Packet Tracer does, do you need to buy your own home networking equipment to experiment with? No, you don't. I have a friend who passed the CCNA certification exam by only using Cisco Packet Tracer. On the other hand, if you can afford to buy a home networking kit, then more power to you. Buying a home networking kit consisting of a router, a couple of switches, and so on is an interesting idea. Perhaps I will write about this topic in another post. Another possible downside to Cisco Packet Tracer could be that if you already have networking experience, you might find Cisco Packet Tracer to be on the simple side of things.

Cisco Modeling Labs

In addition to Cisco Packet Tracer, Cisco also offers Cisco Modeling Labs. From what I can tell, Cisco Modeling Labs is a more advanced version of Cisco Packet Tracer. Cisco Modeling Labs apparently gives the user more options and greater flexibility in creating networks than what is offered by Cisco Packet Tracer. I have got to admit, the user interface for Cisco Modeling Labs looks pretty slick. There is a downside to Cisco Modeling Labs, however. The downside is that Cisco Modeling Labs is not free. A one-year license for personal use will cost you around $199. Still, that's cheaper than buying your own networking equipment. I have never met anyone who has used Cisco Modeling Labs, so I don't know if the application is worth the money. When the time comes to kick Cisco Packet Tracer to the curb, I might give Cisco Modeling Labs a try.

The GNS3 Option

Don't want to use the CCNA 200-301 Network Simulator, Cisco Packet Tracer, or Cisco Modeling Labs? Well, GNS3 just might be the networking application you have been looking for. From what I can tell, GNS3 will let you create complex networking topologies with the best of them. It also helps that the graphics definitely catch the eye in a way that Cisco Packet Tracer doesn't. According to the documentation, GNS3 is free and open source. Not only that, GNS3 will provide you with all kinds of options that are not provided by Cisco Packet Tracer. There is an important caveat to mention about GNS3 before you might consider using it. GNS3 does not use the Cisco IOS. If you want to use the Cisco IOS, or any other vendor's CLI, with GNS3, you will have to install Cisco IOS into GNS3. That means either getting a license to use Cisco IOS or copying it from another device. On their website, there is a proclamation that GNS3 is "by network pros for network pros". That statement is a good indicator that GNS3 might not be the best program to use if you are brand new to networking. I see that GNS3 is used by at least 20 high profile organizations for network planning and testing. As a result, you might want to wait until you get some networking experience under your belt before downloading GNS3 onto your laptop. Did I write that GNS3 looks really cool?

In Conclusion

For now, I will be using both Cisco Packet Tracer and Pearson Vue's CCNA 200-301 Network Simulator for studying for CCNA. At some point, I would like to try out Cisco Modeling Labs.

Module 4: IPv6 Addressing...

Starting New Course Module

Yesterday, I F-I-N-A-L-L-Y started "Module 4: IPv6 Addressing" in the Network Addressing and Basic Troubleshooting Course from the Cisco Networking Academy.

Module 4: IPv6 Addressing

The first three modules in the online course ("Physical Layer", "Data-Link Layer", and "Routing at the Network Layer") took longer than anticipated to complete.

I am far behind where I want to be in terms of completing this online course.

What is IPv6?

In its simplest form, Internet Protocol version 6 (IPv6) is the new method for assigning addresses to hosts on a computer network. IPv6 was designed to eventually replace Internet Protocol version 4 (IPv4), which is/was the most popular method for assigning addresses to hosts on a computer network. IPv4 is starting to lose its usage dominance to IPv6 due to a variety of factors. The main reason why IPv6 is being adopted widely is that we are running out of unique IPv4 addresses to use. Why are we running out of IPv4 addresses to use? Well, for computer netowrks to operate properly, each host on the network needs its own unique IP address IOT communicate with other hosts on the network. Due to the explosion of desktop computers, laptop computers, servers, printers, switches, routers, cell phones, tablets, wearable technology, and the Internet of Things, the pool of available IPv4 addresses has been nearly exhausted. As a result, IPv6 was created to solve the issue of IPv4 address exhaustion. In addition, IPv6 was designed to be more flexible than the rigid structure of IPv4. Thus, IPv6 is in many ways radically different from IPv4, yet IPv6 serves the same purpose. Plus, like everything in IT, the technology changes. When technology changes, there is usually greater flexibility and more options available.

Here are two examples of an IPv4 address:

• 192.168.1.5
• 185.107.80.231

Here are two examples of an IPv6 address:

• 2001:0000:9d38:6ab8:1c48:3a1c:a95a:b1c2
• 0123:4567:89ab:cdef:0123:4567:89ab:cdef

See the differences between IPv4 and IPv6 addresses?

Here is a good chart that shows the differences between IPv4 and IPv6 addresses that just happened to show up on my LinkedIn feed recently.

Differences between IPv4 and IPv6 addresses

Anyway, the time to start implementing IPv6 is now.

The time to start learning how to use IPv6 is now.

Like I wrote earlier, the purpose/function of IPv6 is the same as IPv4. However, it is quite different from IPv4 in many ways.

Just know that there is A LOT of information out there on the internet that covers the differences between IPv4 and IPv6. I kid you not. I just might even make my own contribution to about information about IPv6 on the internet. I haven't decided.

That said, I STILL need to read Chapters 11, 12, 13, and 14 on IPv4 Addressing in the CCNA 200-301 Official Cert Guide. I keep putting it off. Well, guess what? That needs to change. I need to sit down and work through those four chapters as IPv4 won't be going away any time soon.

To be honest, when I originally studied for the CCNA certification from Cisco, I got bogged down in the chapters for Part III: Implementing VLANs and STP. Therefore, I never made it to Part IV: IPv4 Addressing.

I will have to work on rectifying that as soon as possible.

Attending the Phoenix Polish Festival 2024...

Attending the 19th Annual Polish Festival

Way back on Saturday, April 13th, 2024, I attended the 19th Annual Polish Festival on the grounds of Our Lady of Czestochowa Parish in Phoenix, AZ.

19th Annual Polish Festival Website

My sister informed me that she was going to attend the 19th Annual Polish Festival. She said that she had always wanted to go. However, in previous years, she said that something always came up at the last minute. After performing a quick internet search I noticed that this year's Polish Festival was being held on April 13th and 14th of this year. My sister said that she was going to go to the Polish Festival on Saturday, April 13th. As a result, I made plans to attend the Polish Festival that day as well.

Getting to the Polish Festival

When Saturday, April 13th, arrived, I made the drive out to Our Lady of Czestochowa Parish. I drove east on Bell Avenue out of Sun City and drove past Highway 101 and the Arrowhead Towne Center shopping area. I made a right turn onto 67th Avenue. After a short distance, I made a left turn on Greenway Road. I was suddenly driving in an area of Glendale, AZ I had never been in before. Suddenly, I could tell that I was officially driving in Phoenix because the City of Phoenix logo was present on all of the road signs on the traffic lights. Once I got to 29th Avenue, I made a left turn and looked for a parking spot at the NAU-North Valley branch campus. From there, the organizers of the Polish Festival had a shuttle van that would drive you over to Our Lady of Czestochowa Parish a short distance away to the south.

Location of Our Lady of Czestochowa Parish

Food and Drink at the Polish Festival

The Polish Festival itself was held on the grounds of Our Lady of Czestochowa Parish. Right in what would be the parking lot. The Polish Festival was organized along the lines of going to Oktoberfest. In order to get food or drinks, you had to purchase tickets from the ticket counter. There were row upon row of tents that offered Polish food. For 22 tickets, I got the combination platter, which consisted of Polish sausage, stuffed cabbage, several pierogies, a large potato pancake, and a couple slices of bread. You could get some food items, such as pierogies or sausage, al a carte. There was even a line for crepes. There were also tents offering Polish-themed desserts. For alcoholic drinks, you had a choice between beer or wine. For beer, there was only one brand of beer offered: Zywiec Pale Lager. Zywiec is pronounced as "Zhi-vietz". Just as an aside, the Zywiec Brewery was founded in 1856 by Archduke Friedrich von Habsburg, a member of the Habsburg Royal Family in Austria-Hungary. Currently, the Zywiec Brewery is owned by the Heineken Group. Zywiec Pale Lager beer is pretty decent. Zywiec is the name of a small town where the brewery was founded. Since it was a H-O-T and SUNNY day, the beer was refreshing.

Zywiec Pale Lager Beer

The Polish Festival Itself

Besides food and drink there were was a tent that offered all kinds of souvenirs (t-shirts, polo shirts, hoodies, baseball caps, scarves, drinking glasses, key chains, etc.) for sale. The tent was doing brisk business. I thought about buying a couple of souvenirs, such as a baseball cap, a scarf, and a replica Polish Men's National Team soccer jersey, but I ultimately changed my mind at the last minute. There were tents for various Polish-American associations and charity groups. Then there were the usual vendors that you would typically see at a public event. There were two large tents with tables and chairs for people to sit and eat. When I got to the Polish Festival, seating was standing room only. The Polish Festival was actually fairly crowded. I was surprised by the large attendance. There were people everywhere. In front of the two large tents, there was a performance stage. The festival organizers brought in dancing troupes from both Tucson and Los Angeles to perform traditional Polish folk dances while wearing Polish folk costumes. Since the temperature had to be at least 90 degrees that afternoon, I am sure that the dancers were hot and sweaty. The disc jockeys even played a Polish song that was quite similar to the "Chicken Dance" song that gets played ad nauseam at Oktoberfest. There was a playground for little kids to play. It shouldn't have been a surprise, but there was a sizable monument to Pope John Paul II, known in Polish as Jan Pawel II. Thinking about it now, I never bothered to go inside the church itself and take a tour. As a result, I didn't get to see any of the artwork, sculptures, or architecture. Incidentally, Czestochowa, Poland is home to the famous Black Madonna of Częstochowa religious artwork, which is housed at the Jasna Góra Monastery. Oh well, as the saying goes, maybe next year.

The Photos

My photos from the Polish Festival are quite disappointing. At the time, I wasn't posting to my blog, so I wasn't taking photos with the idea of posting them to my blog. I noticed that the longer I was at the Polish Festival, the less energy I had. Since I bought so many tickets, I ended up drinking four or five beers. Plus, it was an abnormally hot day for the middle of April and shade was in limited quantity due to large number of people at the festival. Next year, I will take more photos.

In Conclusion

All-in-all, I had a good time at the 19th Annual Polish Festival. I went in with no expectations and was pleasantly surprised. You can show up, get some food, drink a beer or two, and hang out for an hour or two. Take a tour of the church. I recommend that you wear a long-sleeved shirt and a wide-brimmed hat just in case.

New CCNA Certification Guides...

New CCNA Certification Guides

Well, it's official. Cisco Press will be publishing new official certification guides for CCNA 200-301.

I first learned about the new certification guides on my Twitter/X feed.

This was bound to happen as the current versions of the CCNA 200-301 Official Cert Guide were published in 2020.

According to Cisco Press, the new version of the CCNA 200-301 Official Cert Guide will be published on July 22, 2024.

As per usual in an update like this, there will be changes in the certification guide because technology is always changing.

I don't think that there will be anything too radical about the material in the new certification guides. I don't think Ethernet cables are going away anytime soon.

Apparently, there will be a section in the textbooks that will cover artificial intelligence (A.I.) simply for the fact that A.I. is all the rage.

One change will involve making the PDF/ePub versions the preferred version of the certification guides. Cisco Press will still publish and sell both volumes of the certification guides in hardcover, however. I suppose the idea is that the authors (Wendell Odom, David Hucaby, and Jason Gooley) can provide embedded links for additional learning material in the electronic versions that they cannot provide in the hardcover versions. Let's face it, there are things you can do with PDF files that you cannot do with the printed page.

Moreover, the new version of the CCNA 200-301 Official Cert Guide will contain 12 separate exams that feature 1,300 questions. In addition, there will be practice certification exams that you can take using a timer as practice for the official certification exam.

There's bound to be additional changes, improvements, and new features in the new certification guides. I'm sure that more information will be revealed as we get closer to publication date.

Here is a link to Wendell Odom's Certskills website/blog for more information about the new certification guides.

You can also check out Wendell Odom's Twitter/X feed here as weall.

My Current Progress

Right now, I am working my way through the "Network Addressing and Basic Troubleshooting" online class over at the Cisco Networking Academy website. I have just started the training module about IPv6.

In hindsight, when I started taking the free online courses in networking from the Cisco Networking Academy, I probably would have been better off ditching the online courses and restart studying for the CCNA certification exam from square one. On the other hand, I have learned quite a bit about networking since I have started working my way through the online courses. There are trade-offs to be sure. The idea I had was to complete these online courses from Cisco as a way to get my foot in the door for a new IT job.

However, the impending publication of the new certification guides will not stop me from reading my current copies of the CCNA 200-301 Official Cert Guide. That's for sure.

The State of My Blog...

The State of My Blog

For the past few weeks, I have re-discovered my interest in blogging on my blog here at Blogger.

Overall, I am pleased with the results.

However, I know that things could be better with my blog.

Here is an unordered list of things right off the top of my head.

• I NEED to re-write and/or update some posts on already published to my blog.
• I NEED to publish posts to my blog at least once per day.
• I NEED to work on my backlog of posts that I want to publish to my blog.
• I NEED to do a better job at advertising about my blog (Facebook, LinkedIn, Twitter/X, etc.) IOT increase my audience.
• I NEED to do a better job at planning on what items a new post will contain.
• I NEED to try and incorporate more challenging HTML techniques into my blog.
• I NEED to try to write about local items of interest, such as news items for Glendale, AZ and Peoria, AZ.
• I NEED to get my blog approved for AdSense, so I can make some extra money off of my blog.
• I SHOULD try to write more posts about IT subjects, such as studying for CCNA.

Like I just wrote, that is a list right off the top of my head on things I can do to improve my blog.

Let's face it, it takes time to write and put together a good post. There is a reason why some bloggers spend a large portion of their day trying to come up with a really good post.

I also have some blogging ideas favorited on my Pinterest account. It's been awhile, so I should take a look at those.

It's not easy as I have A LOT of things to do and A LOT of things that I want to do.

It's all about small, incremental progress.

Unfortunately, it's the most frustrating kind.

Going Kayaking with REI (UPDATED)...

Learning to Kayak Class

On Saturday, May 18th, instead of going hiking, I attended the "Learning to Kayak" class given by REI at Lake Pleasant, AZ.

REI Learn to Kayak Class (Source: REI)

This was my third attempt at attending this class. Back in December 2024, I had to cancel my reservation due to an operation at the VA Hospital in downtown Phoenix. I then registered to take the class this past April. A week before the class, I received an email from REI informing me that the class had been cancelled due to low enrollment.

The goal of the class is to teach participants the fundamentals on how to use a kayak. According to REI's website, here are the goals of the class.

• Learn how to launch and stay comfortable in a kayak
• Practice the forward, reverse, and sweep paddle strokes
• Get exposure to the fundamentals of on the water safety

Here is the Gear List for the class.

• Required items to bring:
• Sun Protection - Lip balm, sunscreen, wide-brim hats, etc.
• Water Shoes/Sandals - Foot attire that will protect your feet and is okay to get wet. (e.g. Teva, Chaco, Keen (not flip-flops)
• Synthetic Quick Dry Clothing
• Water Bottle
• Personal Prescription Medications - Including, but not limited to, epinephrine auto-injectors for anaphylactic allergies.
• Optional items to bring:
• Lip Balm/Protection
• Sunglasses
• Wide Brim Hat w/ Retainer - Sun protective and safe in case of wind
• Paddling Gloves
• Waterproof Camera
• Towel - Quick Drying and Lightweight
• Swimwear
• Tip for guides - 10-20% of program price is recommended.
• Items provided by REI:
• Dry Bag
• Group First Aid Kit - Our guides carry a comprehensive first aid kit, but you are welcome to bring any personal first aid-items that you prefer.
• Paddle
• Lifejacket
• Kayak

Getting to Lake Pleasant

The "Learning to Kayak" class was being given at Fireman's Cove at Lake Pleasant.

Fireman's Cove at Lake Pleasant, AZ (Google Earth)

On Google Maps, getting to Fireman's Cove appears to be relatively easy to do. You drive north on Lake Pleasant Parkway, making a left at State Road 74 (Morristown New River Highway). After several miles, you then make a right at N Castle Hot Springs Road and head north. After five or six miles, you then make a right at Castle Creek Drive. You then follow Castle Creek Drive to Fireman's Cove. REI did place signs along the side of the road at N Castle Hot Springs Road and again at Castle Creek Drive. I don't remember seeing a sign for Fireman's Cove, but I did see a large number of people and parked cars near the beach along Castle Creek Drive. I drove into the parking lot and then noticed the white Ford pick-up truck with the REI logo on the side.

I found the right place.

The most difficult part of the drive to Fireman's Cove was the gridlocked traffic that I encountered on the Lake Pleasant Parkway between Highway 303 and State Road 74. At Highway 303, the Lake Pleasant Parkway truncates into one lane going north and one lane going south. Moreover, the Arizona Department of Transportation was also doing roadwork nearby, causing traffic to tangle up. It was literally bumper-to-bumper traffic all the way to State Road 74. Crazy stuff.

Learning to Kayak

The main guide from REI was named Dave. He said that he lived in Mesa, AZ and came from the REI located in Chandler, AZ. He also said that he was originally from Roanoak, VA and had lived in Washington, D.C. and Seattle, WA. He said that he had been a professional guide for several years. The assistant guide from REI was from Tucson, AZ. His name was Simrin. He said that he had been working as a professional guide since January of this year.

The guides brought hard-shell kayaks with them. The kayaks they brought came in two lengths, 12.5 feet and 14 feet. In contrast, when I attended the sunset kayaking class back in April, also at Lake Pleasant, the REI guides brought inflatable kayaks to use. What are the differences? Well, the inflatable kayaks are difficult to control, yet they rarely tip over. For hard-shell kayaks, the longer and narrower the kayak, the faster it will go. I ended up with a 12.5 foot long kayak to use. The 12.5 foot kayak was a little wider than the 14 foot kayak.

The initial topics covered in the class were the different parts of the kayak, how to hold the paddle, and how to get into the kayak. Dave also covered the basic paddle strokes.

After that, we got into the water. The water felt refreshingly cool. It was a sunny, hot day at Lake Pleasant. At 12:00 PM, when the class started, the temperature had to be close to 100 degrees Fahrenheit. I had trouble signing the release as the table was sizzling hot. Once we got out on the water, you quickly forgot about the heat.

Once we got away from the crowded beach, Dave reviewed the three or four paddle strokes that he had demonstrated on the beach. The entire group spent the next half hour or so practicing the various basic paddle strokes, such as going forward, going backward, and how to turn the kayak to change the direction of travel. As people got more comfortable, the group went past the No Wake buoys and approached the main part of Lake Pleasant. However, we stayed within sight of Fireman's Cove. We encountered waves caused by speed boats passing by. We also experienced having to deal with both the water current and the wind constantly changing direction. It was a challenge.

At around 2:30 PM, Dave asked the group if people wanted to continue kayaking for the next half hour or return to the beach. I wanted to stay out on the water. I guess I was in the minority as the group headed back to the beach. However, there was a twist. We were supposed to try kayaking backwards as far as we could. The wind and current kept taking me off course, so I turned around my kayak and began to paddle forward.

Camera Problems

During the kayaking class, I had ALL KINDS of problems with the camera app on my cell phone. The user interface on my cell phone would freeze. When I tried to open the camera app, I would get a black screen. I also had problems zooming in and out. Then, I would have problems with the waterproof case I kept my cell phone in as I kayaked. As a result, I didn't take many photos during the class. I know, it's time to seriously consider getting a new cell phone. While I am thinking about it, it's probably time to see if I can find a new waterproof case for my cell phone.

Anyway, here are the photographs that I took as disappointing as they are.

In Conclusion

Was the "Learning to Kayak" class worth the $119 (for REI members) that I paid? Yes, it was. The two guides, Dave and Simrin, were great. They were friendly, approachable, and good at explaining the subtle techniques of learning to kayak. Dave was especially fun as he had lived in the Washington, D.C. area for several years and had been to Baltimore several times. He even agreed with me that the Phoenix metropolitan area DESPERATELY needs a subway. Anyway, given my previous kayaking trips along the Potomac and Monocacy Rivers, the "Learning to Kayak" class was a really good refresher on the basics. If you haven't been kayaking before, then I would highly recommend taking the class. As it just so happened, there is a kayak rental place at Fireman's Cove called Desert Breeze Kayaking Tours. Definitely a place worth checking out.

Skills Required in Different IT Specialties

Some Background

Ever since I decided to go into information technology (IT), I have been overwhelmed with all of the various certifications that are out there. After I earned my CompTIA A+ certification a couple of years ago, I tried to study for CompTIA's Network+ certification. It was an ABSOLUTE, COMPLETE, and TOTAL mess!!! Trying to study for the Network+ certification was like trying to study for three or four separate IT certifications at the same time. Let's see, for the Network+ certification, you needed to know about configuring routers and switches, how to configure servers with Microsoft Server, how to use Microsoft Active Directory, and how to use a network monitoring program like Wireshark. The Official CompTIA Network+ study guide that I was following along with used Microsoft's now-defunct Network Monitor program. I even paid $700 to CompTIA for online exercises for Network+ that were WORTHLESS. Ironically, for a certification that was supposed to be vendor neutral, everything about routers and switches was about Cisco routers and switches. Not a single mention about routers and switches from other vendors, such as Palo Alto Networks or Hewlett Packard Enterprise.

As a result, I became HIGHLY DISCOURAGED with studying for Network+. A co-worker at the Tier 1 IT help desk at the Social Security Administration suggested that I give studying for CCNA a try.

Studying for CCNA

At first, studying for CCNA was a breeze compared to studying for Network+. The study guides for CCNA focused exclusively on Cisco routers and switches. Before I got really busy with work, I made slow, steady progress through the first ten chapters in the first CCNA study guide. Perhaps more importantly, the author of the CCNA 200-301 Official Study Guide, Wendell Odom, had a section about career planning in IT. It was an intriguing read. You can read the series of posts about career planning for those going into IT here. I read each post and actually wrote down some ideas on what I wanted to do with IT. Like I wrote earlier, I had a span of time where I got really busy with my job. I put aside studying for CCNA. I put aside my nascent attempts at some kind of career planning.

After moving from Maryland back to Arizona after 13 years, I have restarted studying for networking. Instead of studying for CCNA directly, I made the decision to work my way through the online networking classes available from the Cisco Networking Academy. My original intent was to complete the online networking classes as a way to establish a foundation in networking PRIOR to making another attempt at studying for CCNA. Another factor for studying the online networking classes was that it became rather apparent to me that I needed to add some IT certifications on my resume IOT get out of working at a Tier 1 IT help desk.

Skills Required in Different IT Specialities

Getting back to the interesting graphic from the Cisco Networking Academy that just randomly appeared in my LinkedIn feed, I was immediately intrigued when I saw it. The graphic gave recommendations on what subjects to study for four different IT specialties. Want to be a software engineer? Then you need to study Python, C++, Java, and Scala. In other words, you will want to study the major programming languages. Want to be a web developer? Then you need to study HTML 5, CSS, JavaScript, and PHP. Again, you need to know how to use the most popular applications. Want to go into computer networking? Then it gets tricky. The graphic recommends that you study networking (preferably CCNA), have an analytical mind (for problem solving), have communication skills (for communicating with non-technical customers), and be able to read and understand reams of documentation (researching an answer is a valuable skill). Let's see, I have really good communication skills. I can simplify complex subjects for non-technical people to understand. For the analytical mind piece, I already worked as an intelligence analyst for the Army for almost nine years. All I need is that CCNA certification. Want to work in cyber security? Cisco recommends knowing how to use the Linux operating system, know about computer networking (again, CCNA), know how to program (Python), and have an analytical mind. In addition to computer networking, cyber security is also a field that interests me. For whatever reason, I cannot tell you why I never got around to studying for, say, CompTIA's Security+ certification for cyber security. Cisco also has its own cyber security certification. For Linux, I have played around with Ubuntu on a previous Dell laptop. When I had to buy a new Dell laptop back in November, I wanted to install either Debian or OpenSUSE. Unfortunately, my brand new Dell laptop doesn't have enough memory to do so. Currently, I am learining about computer networking. I have tried to learn how to program in Python on previous occasions. I need to try again, but make it my only focus. Lastly, for the analytical mind piece, I worked as an intelligence analyst for the Army.

In Conclusion

The graphic from Cisco gives me a guide on what to study for CCNA. That said, I also should get certified in Microsoft Windows Server and Microsoft Azure, for example. On their own, those two certifications will add punch to my resume. From what I have seen, those are the certifications that get noticed on a resume. There is always a demand for those certifications. When I complete my last CCST online course, I just might move over to studying Microsoft Windows Server and Azure. We'll see. Another possible option would be to find a location in Peoria, in Glendale, in Surprise, or in northern Phoenix that offers in-class learning for CCNA. With the new CCNA study guides coming out soon, that might be the way to go. On LinkedIn Learning, I found what appears to be a really good class on the Python programming language. I just might give that a try. Again, knowing how to program in Python is a good thing to have on your resume. Unfortunately, there are only so many hours in a day.

Attending the Electrify Expo, Part 2...

Second Half of the Electrify Expo

This is my second post about attending the Electrify Expo at State Farm Stadium in Glendale, AZ on Sunday, May 5th.

If you want to read my first post about the Electrify Expo, then click on this link. I also posted quite a few photographs that I took of the event.

This post will focus on what I saw after I left the main exhibition area.

Celsius Energy Drink

After looking around the exhibition booth for Nikola Motor, I picked up a complimentary can of Celsius Energy Drink. The can was ice-cold. The temperature was above 90 degrees, so it hit the spot. I don't remember what flavor I drank.

Modifications and Customizations

The next exhibits of the Electrify Expo consisted of vendors that would customize or modify your EV, such as new tires, custom paint jobs, custom parts, and various other methods to modify your EV. For me, the exhibits became interesting when I came across a vendor that were selling customizable camping tents that mounted on the back of a Rivian pick-up truck. That was interesting to see. I knew that Rivian on their website also offers a camping tent that you can attach to your pick-up truck. Not too sure if they were the same product, however. There was even tubing that you could run from the air conditioner to the camping tent for heating or cooling. There was a vendor that was selling an all-electric camping trailer. Another vendor was even selling an entire field kitchen that could be powered by your EV.

Here are some photos that I took.

E-Bikes and E-Scooters

The next section of the Electrify Expo consisted of all of the electric bike (E-bike) and electric scooter (E-scooter) vendors. From what I saw, the price range for an E-bike ran from as low as $2,000 to as high as $9,000. I have to admit that I am not too interested in E-bikes, yet I can see where having one could be useful, such as riding up a steep hill.

The Heritage at Sportsman's Park

All of this walking around made me really hungry, so I was happy when I came across The Heritage at Sportsman's Park. I had never heard of The Heritage at Sportsman's Park before. It was really nice. The Heritage at Sportsman's Park is a three-story structure. The ground floor has a kitchen where you can order food and drinks. The second and third floors have several large flat-screen TVs and tables and chairs. I think the third floor has a bar. Basically, The Heritage at Sportsman's Park is a restaurant, a sports bar, and a nightclub in a relatively small three-story building. Apparently, you can even rent out the place for weddings or corporate parties. It's nice. I ordered a Sonoran hot dog with an iced tea. It was pretty good, but pricey at $18.

Testing Out EVs

After eating my Sonoran hot dog, I followed the crowd to the next section of the Electrify Expo. In the third section of the Electrify Expo, the organizers set up a couple of racing tracks for trying out EVs. On one track, you could check out an E-bike or an E-scooter and ride for a couple of laps. On a second track, Ford Motors set up a small test track where people could ride as passengers as a professional test driver drove a Ford Mustang EV. BMW and Kia had a similar set-up for their EVs. I think that Tesla was letting spectators ride as passengers as professional test drivers drove on the streets around State Farm Stadium. I didn't try riding an E-bike or ride shotgun on an EV. Again, these companies wanted your personal information for marketing purposes. The companies were also trying to screen for potential buyers. I was content with watching other people. The problems with the racing track area were that shade was in short supply and there wasn't anything available to drink.

In Conclusion

I had a good time at the Electrify Expo. It was DEFINITELY worth the $20 I paid for a ticket. If you are curious about electric vehicles, then I RECOMMEND that you visit the Electrify Expo. Just as a disclaimer, I do own stock in Tesla, Lucid, Rivian, Nio, and Xpeng. Do I own an electric vehicle? No, I do not. I am still driving my 2010 Nissan Maxima that I bought with money I earned from working in Afghanistan. However, my car is rapidly approaching the 100,000 mile mark.
