There are quite a few changes in this exam objective update, so there’s quite a bit to discuss for those of you currently preparing for this exam or those of you who have got it on your to do list. One of the big overall changes I’ll cover is that the exam is slowly but surely moving away from being as heavily IaaS focused, with PaaS based objectives expanding further than they had previously.
The best examples of this are once you get into the Deploy and manage Azure compute resources section, where it is easily seen. What are the differences? There is a major expansion in the Azure Container Instances (ACI) and Azure Kubernetes Service (AKS). These started off with an item for each, but have now expanded into further deployment and management areas, so it’s not enough to just know why and when you would use containers, and determine if AKS or ACI was the appropriate offering, now you need to now more about their day to day operations. The updated objectives do help to guide you though.
A similar change has occurred with App Service Plans and App Service, which were limited to an item each previously. Now there is more of an expectation of not just knowing the basics and when to use a certain plan, but you also need to know hot to integrate them into existing environments. Just like with the containers objectives, there is clear guidance as to what you need to be prepared for in the exam with the expanded objectives.
Before I move on to some of the other changes, why are these two compute changes so important? The expectation of what an Azure Administrator should be familiar with constantly evolves, and while many admins maybe have been able to take their on-premises knowledge of virtual machines, operating systems, networking and storage across to Azure with little effort, there is now an expectation that some of those IaaS workloads are slowly but surely being moved across to PaaS offerings. Notice I’m not saying all workloads are expected to move, but some of them certainly are. If you have come from more of an IaaS background, this means you will need to focus on these areas.
This doesn’t mean that those focused on PaaS workloads don’t have to put in effort as well. Understanding networking technologies and and traditional compute models is still a major, though shrinking part of the exam, and one of the common issues I’ve seen with people who fail this exam is that it’s a lack of core networking skills that let them down. There have been some consolidations in the networking sections of the exam, but the reality is that nothing has been removed, with the assumption that an admin has a basic level of knowledge of networking concepts.
Regardless of where your skills are strongest, the important thing is to focus on your weakness with your exam preparation, rather than getting too carried away learning about the things you already work with. An example of this is that if you work mostly with SaaS via Microsoft 365, you may already have a strong enough set of skills to get through the identity questions without a challenge. Instead go through the resources listed below to make sure you aren’t missing anything before sitting for the exam.

Hi Mark,
This preparation helps me a lot. I can’t express my appreciation for your great job. Do you have any plan to prepare for AZ 303/304 exam?
Sincerely,
Tony

Hi Tony
No plans to do guides for AZ-303/304 at the moment. If work pulls me back in that direction I’ll publish something.
