I recently passed the VCP-VMC 2023 exam, which was made possible by the free VMware course that allowed me to check the prerequisite for the certification. For those looking to take on the exam, I'll include what I can remember in terms of general concepts.
For starters, and as per usual with any VMware exam, start with the exam guide.
Like anything to do with cloud, it is network heavy. I'm not a networking engineer but have a long-since lapsed CCENT certification. This exam is going to grill you on CIDR, subnets, and network overlaps, and assumes that you have a general knowledge of the OSI model. Focus as well on the different connection and VPN types for each cloud provider. While it primarily focuses on AWS, GCP and Azure questions were in there as well, so be sure to know what each provider supports for configuration minimums and maximums regarding management networking configuration.
Speaking of minimums and maximums, you'll want to read up on cluster sizes and hardware configurations. What are the specs of an i3.metal instance vs. an i3en.metal? What kind of nodes can you get with Azure and GCP? And how many can you throw into a cluster? All of these may appear on the exam.
Managed services, such as VMware Cloud on Dell EMC and AWS Outposts should be studied as well. What physical requirements do these carry? What are their responsibilities?
HCX... woo boy. Several of these questions showed up, and did nothing but generate anxiety. Get to know HCX. Get to know the deployment models, and read up on how to troubleshoot different scenarios.
Containers, Kubernetes and Tanzu all showed up on my exam. Know what TKG does, how to deploy it, what value Kubernetes brings to containers in general, and what Tanzu services do what function.
That's all I can remember as of this moment. I'm still kind of pumped from getting through it. The only feedback that I have is that I don't know if some of my answers were right as they may have changed after the exam was written. For instance, Google has updated their networking requirements as of November 2022, so I'm not sure if I got the question wrong by answering based on current requirements, or if I should've answered based on previous specs. Perhaps a higher-level question that isn't dependent on something that can change with relative frequency would be better.
I hope you found this helpful. Feel free to comment below or ping me on Twitter if you have any questions!
