The VMware vSphere with Tanzu Specialist exam (5V0-23.20) validates your ability to design, deploy, and manage containerized workloads within vSphere environments using Tanzu technologies. This certification is intended for infrastructure professionals and architects who work with VMware vSphere and need to demonstrate expertise in Kubernetes integration and container orchestration. This page outlines the exam structure, key topics, and effective study strategies to help you prepare confidently. Whether you're advancing within the VMware Specialist path or building your Tanzu expertise, understanding the exam's scope and format is essential for success.
Use this topic map to guide your study for VMware 5V0-23.20 (VMware vSphere with Tanzu Specialist) within the VMware Specialist, vSphere with Tanzu certification path.
The 5V0-23.20 exam uses a mix of question types to assess both conceptual knowledge and practical decision-making in real-world scenarios. Questions progress in difficulty and emphasize applied understanding rather than memorization alone.
Questions are designed to reflect the decisions and troubleshooting you'll perform in production environments, ensuring your preparation translates directly to job readiness.
An effective study plan breaks the seven topic areas into manageable weekly goals, combines self-study with hands-on practice, and includes regular progress checks. Dedicate time to understanding how each topic connects to real deployment and operational workflows.

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.
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.
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.
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.
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.
What should be increased or reduced in order to scale a Tanzu Kubernetes cluster up or down?
Which step in vSphere with Tanzu enablement using the vSphere Distributed Switch process is done prior to using the Workload Management Enablement Wizard?
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.
What is the correct process to store images in a project on the Registry Service?
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>/
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]

What provides the North-South connectivity from NSX-T Data Center to the physical infrastructure?
Which three elements should be configured by a vSphere administrator after creating vSphere Namespace? (Choose three.)
Creating a Namespace
A vSphere administrator configures permissions and storage before a namespace can be used:
* Assign edit or view permissions to users. Users must be present in a configured single sign-on (SSO) identity source.
* Must assign a VM storage policy to the namespace.
* Can define resource limits (optional).
* Must add a content library to enable the Tanzu Kubernetes Grid Service.
