A Supervisor Cluster shows intermittent node communication issues. You suspect an MTU mismatch impacting encapsulated traffic. Which troubleshooting approach is most appropriate to confirm and isolate an MTU-related problem in a vSphere with Tanzu environment?

After enabling vSphere with Tanzu on a cluster, a developer asks where they should go to create namespaces that map to Kubernetes namespaces and apply resource limits. Which object should the vSphere administrator create and manage?

A team wants Tanzu Kubernetes clusters to use a specific vSphere storage policy for their persistent volumes by default, without developers having to specify it on every claim. What is the recommended place to set this default?

An administrator needs to quickly determine whether vSphere with Tanzu has been enabled on a cluster and if the Supervisor is running. Where is the most direct place to validate this in vSphere?

A security team requires that only members of a specific Active Directory group can access a vSphere Namespace and create workloads. Which action best meets this requirement?

A developer reports that Kubernetes worker nodes in a newly provisioned Tanzu Kubernetes cluster remain in a NotReady state. The vSphere administrator sees that the VMs are powered on and have IP addresses. Which issue is the MOST likely cause to check first?

An organization wants consistent governance across multiple teams using vSphere with Tanzu. They need to ensure each team can only consume a defined amount of CPU/memory and can only use approved storage policies. Which combination best achieves this?

A platform team is designing access to container images for workloads running on vSphere with Tanzu. They want an enterprise approach that supports authentication/authorization, scanning integration, and centralized image management. Which solution is most appropriate?

An administrator enabled Workload Management, but kubectl access to the Supervisor cluster API intermittently fails with timeouts. vCenter appears healthy. Which design-related issue is the MOST likely cause?

A multi-tenant environment uses multiple vSphere Namespaces. The security team requires that workloads from different namespaces must not communicate unless explicitly allowed. Which approach best aligns with Kubernetes-native controls in this scenario?

A production cluster running vSphere with Tanzu must undergo host remediation. The goal is to maintain Kubernetes API availability for the Supervisor during ESXi host maintenance. Which action is MOST appropriate before placing a host into maintenance mode?

An administrator wants to give developers kubectl access to the vSphere Namespace while ensuring they can only deploy workloads within that Namespace. Which vSphere construct should be used to grant this access?

A platform team needs to ensure that Kubernetes workloads deployed by developers cannot consume more than a defined amount of CPU and memory in a vSphere Namespace. What should the team configure?

An administrator is validating network readiness for Supervisor-based workloads and wants to confirm that Pod-to-Pod and Pod-to-Service networking is handled by the Supervisor’s Kubernetes networking stack. Which component is primarily responsible for container networking on the Supervisor?

A developer reports they can authenticate to vCenter, but kubectl commands against a vSphere Namespace fail with authorization errors. The developer should only have access to that Namespace. What is the most likely cause?

A company wants to separate Kubernetes workloads for two business units while using the same Supervisor Cluster. They need isolation of access control and resource allocation per business unit. What is the best approach?

After enabling Workload Management, an administrator needs to provide developers with a consistent, curated set of Kubernetes versions and node sizing options for provisioning Tanzu Kubernetes clusters. Where should the administrator define these standardized options?

A Tanzu Kubernetes cluster is failing to scale out because new worker nodes remain in a pending/provisioning state. The vSphere Namespace has strict storage requirements and the cluster uses a StorageClass backed by a vSphere Storage Policy. What is the MOST likely reason for the failure?

A platform engineer wants to expose a Kubernetes application running on vSphere with Tanzu to internal users only and ensure traffic is restricted to a specific network segment. Which approach is most appropriate?

An administrator wants to troubleshoot why a Supervisor workload is stuck in a non-ready state. They need to correlate Kubernetes object status with vSphere tasks/events to identify whether the issue is compute placement, storage policy, or networking. What is the best starting point?

A security team requires that only container images from an approved registry are allowed to run, and that policy must be enforced consistently across multiple Tanzu Kubernetes clusters in different Namespaces. Which solution best meets this requirement?

An administrator wants developers to create namespaces and grant access to them without giving the developers permissions in vCenter Server. Which capability should the administrator use?

A team reports that new Pods scheduled to a vSphere with Tanzu namespace remain in a Pending state. Existing Pods continue to run. The namespace has an explicit CPU limit configured. What is the MOST likely cause?
