Frequently Asked Questions

What topics carry the most weight on the 5V0-23.20 exam?

vSphere with Tanzu Core Services, Tanzu Kubernetes Grid Service, and Monitoring and Troubleshooting typically represent a significant portion of the exam. These areas directly reflect the skills needed to deploy and maintain production Tanzu environments. Allocate extra study time and practice questions to these domains to maximize your score.

How do the seven topic areas connect in a real project workflow?

Introduction and Containers/Kubernetes topics provide the foundation; vSphere with Tanzu explains how these concepts integrate into VMware infrastructure. Core Services and TKG cover deployment and provisioning, while Monitoring and Troubleshooting address day-2 operations. Life Cycle management ties everything together by ensuring your clusters remain updated and compliant. Understanding this progression helps you see each topic's practical purpose rather than treating them as isolated subjects.

How much hands-on lab experience is necessary to pass?

While the exam tests conceptual knowledge, hands-on experience with vSphere with Tanzu clusters significantly improves your ability to reason through scenarios. Prioritize labs that cover cluster provisioning, namespace configuration, workload deployment, and basic troubleshooting. If you lack access to a lab environment, detailed scenario-based practice questions can help bridge the gap, but real interaction with the platform strengthens retention and confidence.

What are common mistakes that lead to lost points?

Candidates often confuse Kubernetes-native concepts with vSphere-specific integrations, for example, mixing standard kubectl operations with vSphere with Tanzu-specific management tasks. Another frequent error is overlooking the importance of monitoring and logging in troubleshooting scenarios; many exam questions test your ability to interpret metrics and logs to diagnose root causes. Finally, rushing through scenario-based questions without fully reading the context often leads to selecting suboptimal answers. Slow down, read each question twice, and consider the broader operational context before choosing.

What's an effective study strategy for the final week before the exam?

Focus on high-risk topics identified during your practice tests and review scenario explanations rather than rereading entire study guides. Complete one full-length timed practice test early in the week to gauge readiness, then spend the remaining days reviewing weak areas and doing targeted question sets. Avoid cramming new material; instead, reinforce what you've already learned and build confidence in your reasoning process. Get adequate sleep the night before the exam to ensure mental clarity.

Question No. 1

What should be increased or reduced in order to scale a Tanzu Kubernetes cluster up or down?

Show Answer Hide Answer
Correct Answer: D

Question No. 2

Which step in vSphere with Tanzu enablement using the vSphere Distributed Switch process is done prior to using the Workload Management Enablement Wizard?

Show Answer Hide Answer
Correct Answer: D

As a vSphere administrator, you can enable the Workload Management platform on a vSphere cluster by configuring the vSphere networking stack to provide connectivity to workloads. A Supervisor Cluster that is configured with vSphere networking supports the deployment of Tanzu Kubernetes clusters created by using the Tanzu Kubernetes Grid Service. It does not support running vSphere Pod or using the embedded Harbor Registry.


Question No. 3

What is the correct process to store images in a project on the Registry Service?

Show Answer Hide Answer
Correct Answer: B

https://docs.docker.com/docker-hub/repos/

* Registry Service: Developers can store and manage Docker and OCI images using Harbor. Harbor is an open-source container image registry that secures images with role-based access control.

Procedure

Login to Harbor Registry with the vSphere Docker Credential Helper.

docker-credential-vsphere login <container-registry-IP> --user [email protected]

Note:While providing--user usernameis acceptable for login, you should use the UserPrincipalName (UPN) syntax (--user [email protected]) to login and usedocker pushcommands.

Tag the image that you want to push to the project in Harbor Registry with same name as the namespace, where you want to use it:

docker tag <image-name>[:TAG] <container-registry-IP>//<image-name>[:TAG]

For example:

docker tag hello-world:latest 10.179.145.77/tkgs-cluster-ns/hello-world:latest

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

10.179.145.77/tkgs-cluster-ns/hello-world latest bf756fb1ae65 10 months ago 13.3kB

hello-world latest bf756fb1ae65 10 months ago 13.3kB

To push an image to a project in Harbor, run the following command:Syntax:

docker push <container-registry-IP>/<namespace-name>/<image_name>

For example:

docker push 10.179.145.77/tkgs-cluster-ns/hello-world:latest

Expected result.

The push refers to repository [10.179.145.77/tkgs-cluster-ns/hello-world]
