How to Pass the VCP-NV 2023 Exam: Tips and Resources

Get tips and resources for passing the VCP-NV 2023 exam, including Pluralsight courses, VMware Hands On Labs, home lab practice, and study materials.

If you’re preparing for the VCP-NV 2023 exam, also known as 2V0-41.20, you might wonder what resources can help you pass. As someone who recently passed the exam, I want to share some of the study resources I used and my tips for success.

Pluralsight

One of the best resources I found was the Pluralsight course, VCP-NV 2022: VMware Certified Professional – Network Virtualization (2V0-41.20). This eight-hour course provides a comprehensive overview of networking concepts and includes labs you can follow. I found this course helpful because it explained how things were done differently in NSX-T compared to previous versions.

Hands-On Labs

If you don’t have the resources to run a full NSX implementation in your home lab, I highly recommend using VMware Hands On Labs. This free resource is a great way to learn by doing.

Using Your Home lab

I spent a lot of time practicing with NSX in my home lab. This allowed me to get hands-on experience with the platform and learn how things work in a production environment. I even found a way to install NSX from vCenter that wasn’t covered in the Pluralsight course.

Practice Exams

Unfortunately, I couldn’t find any official practice exams. Instead, I made notes on everything listed in the exam guide and watched resources like vBrownBag‘s YouTube video on NSX-T. Even though the video was for a previous version, many of the concepts were still relevant.

Conclusion

In conclusion, these study resources were invaluable in helping me pass the VCP-NV 2023 exam. I hope they can be of service to you as well. Remember to practice and study consistently, and you’ll be on your way to passing the exam.

How to Resolve Connection Errors Between Horizon and vCenter

Learn how to resolve connection errors between Horizon and vCenter with our step-by-step guide. Follow our troubleshooting steps to get your virtual desktop infrastructure running smoothly.

I was recently working with a client that needed me to migrate Horizon View VMs to new storage. I thought it would be as easy as changing the storage settings for the pool and performing a rebalance across the cluster. Unfortunately, no rebalance operation was successful and I saw the following errors:

Provisioning error occurred for Machine XXX: Refit operation rebalance failed

vCenter at address <vCenter Address> has been temporarily disabled (this error would typically followed by another notification that the same vCenter had been enabled)

I was able to resolve the issue by following VMware KB 1030996. I the case of this customer there was only one working production pool. To test that there was an issue with the pool in use, I created a new temporary pool. I then tried recompose actions and looked for errors in the event log. There were none.

Creating a new temporary pool proved critical to resolving this issue. The crux of the problem as laid out in the KB is that there are two vCenter entries in the composer database. In my case the IP address and the FQDN (The FQDN being the correct entry). The correct Deployment Group ID was displayed in the View Composer Database entry for the new temporary pool I created. I was able to take that ID and replace it in the entries for the current production pool. After that was done, I was able to easily rebalance the production pool.
