How I studied for the AZ-305 Designing Microsoft Azure Infrastructure Solutions Exam

I recently took and passed the AZ-305 exam. I wanted to share some of the resources I used so that they may help someone else take and pass this exam. I took the AZ-104 exam four months before and felt there was a natural progression, but the AZ-305 was much more difficult.

Free Microsoft Resources

There are three resources from Microsoft that I found helpful in studying for this exam. First is the Microsoft Learn portal. It has tons of modules to browse through, especially if you only need help with certain concepts. Second, there is the lab material on GitHub. Third, is the study guide, which gives you an outline of what topics you should fully understand in order to pass the exam.

John Savill’s Technical Training on YouTube

Just as I did in studying for the AZ-104 exam, I relied heavily on John Savill’s videos on YouTube. Specifically, the AZ-305 playlist and the AZ-305 study cram video. These videos were crucial for me to better understand what I had read.

Playing Around in the Azure Environment

Just like with my AZ-104 exam preparation, I cannot overstate how important it is to actually play around in Azure. Create a VM. Create a resource group. Peer a network. All of these things were very important for me to understand how the different services interact.

Using the Official Practice Test from MeasureUp

Once I felt that I had mastered all the concepts, I turned to the official practice test from MeasureUp to ensure that I had a feel for what type of questions would be asked. This helped me bring everything I learned together.


These are the tools that I found invaluable in helping me learn the material needed to pass this exam. I hope that they can be of service to you as well.

How I studied for the AZ-104 Azure Administrator Associate Exam

When I took the Azure AZ-104 exam in August, I was able to pass confidently because I used the following resources. I hope that if you’re studying for the exam, you find the same resources helpful.

Exam Ref AZ-104 Microsoft Azure Administrator

I actually bought and read the physical copy of the exam reference guide from Microsoft. I took it with me everywhere for about a month. Anytime I had to wait for anything, I started reading the book. This helped me build a framework for understanding the various concept the exam covers.

Playing Around in the Azure Environment

I cannot overstate how important it is to actually play around in Azure. Create a VM. Create a resource group. Peer a network. All of these things were very important for me to understand how the different services interact.

John Savill’s Technical Training on YouTube

John Savill’s AZ-104 playlist and study cram video were very instrumental in helping me pull all the concepts together. It is amazing that all his content is available on YouTube for free.

Using Tutorials Dojo Practice Exams

The Tutorials Dojo practice exams helped me bring all the concepts together. The questions were similar in concept to what was in the exam, but crucially, they were not brain dumps. The reason I like practice exams is that I learn to think a little more critically about scenarios that I may experience in real life.


These tools helped me study for and pass the exam. I hope that they help you along in your Azure certification journey.

Common Issues when migrating VMs from VMware vSphere On-Prem to Azure

I have been running a VMware home lab with an old Dell PowerEdge R720 with ESXi 7.0.2 installed. I have been running Azure for backups and Key Vault to protect secrets, but now I want to migrate one of my vSphere on-prem VMs. Through this process, I ran into a few issues and “gotchas” that may affect other users. Below is my list of potential issues you may face and how to resolve them.

    A Note About Whether or Not to Use the Migration Appliance

    I started out choosing to use the migration appliance. I downloaded the OVA and installed it in my lab environment. This initially turned out to be a huge hog of resources without any real benefit for my small lab environment. For that reason, when my project would not allow me to add the migration tool and I had to create a new project, I decided to go with the PowerShell script install on an existing server. If you decide to do the same, remember that you must use a Windows Server OS.

    Issue 1: Azure Migration Project Tool Will Not Add to Your Dashboard

    This was a random issue. Your Azure Migrate project has access to the free assessment tool and the free migration tool. A functioning project should look like the image below.

    A functioning project with the migration tool added

    But the first interaction of my project would not allow me to add that tool. I searched the message boards and could not find a solution to my problem. So, I did the next best thing and started a new project.

    Issue 2: The x86 version of VC++ Redist 2019 may cause the gateway service to fail

    This issue is specific to using the PowerShell version instead of the virtual appliance. This was a problem for me because I had both the x86 and x64 versions of VC++ Redist 2019 installed on my Server VM as shown below.

    I searched for the problem on the internet and found this post in Microsoft’s forum. The advice given was to uninstall both versions, but in my case, that just caused another issue. The solution that worked best for me was to only uninstall the x86 version. Once done, the installation was completed successfully.

    Issue 3: Insufficient Cores Available in the Subscription (During the migration prechecks)

    I worked my way through all the other issues and then ran into this one.

    I had enough cores available in the normal compute SKUs, so this one confused me a bit. The issue, in this case, is that I did an assessment, and used the assessment settings to determine the compute SKU I was going to use but did not properly modify the settings in my assessment. Once I removed reserved instances from my assessment and recalculated the assessment, I got a normal compute SKU and was able to complete my migration successfully.


    While the Azure Migrate tool may not be as easy to use as some of the paid tools, it can be very useful if you are cost-constrained.
