namespace: dev-team-1

subjects:

- kind: User

name: sso:[email protected]

apiGroup:

rbac.authorization.k8s.io

roleRef:

kind: ClusterRole

name:

psp:vmware-system-privileged

apiGroup:

rbac.authorization.k8s.io

The analyst confirms the user is valid in Active Directory.

What is the misconfiguration in the RoleBinding preventing successful interaction/authorization?

24. A Cloud Architect is designing a storage strategy for a Zonal Supervisor deployment across 3 Availability Zones (Zone-1, Zone-2, Zone-3) to support a highly available Kafka cluster.

Requirements:

1. Kafka brokers will be distributed across all 3 zones.

2. Each broker needs a persistent volume for data.

3. If a pod in Zone-1 fails and is rescheduled to Zone-1 (same zone), it must re-attach to its data.

4. If Zone-1 fails completely, the architecture does NOT require the data from Zone-1 to be accessible in Zone-2 (Kafka handles app-level replication).

5. Storage management must be automated via Kubernetes.

Which storage policy design best meets these requirements while minimizing cross-zone latency and cost? (Select all that apply.)

25. A VI Administrator is managing the lifecycle of VM images used by the VM Service. A new corporate standard requires that all Linux VMs deployed via kubectl must use the hardened image corp-linux-v2.ova.

backend:

service:

name: finance-service

port:

number: 80

To avoid modifying every individual Pod manifest to include imagePullSecrets, the Platform Engineer wants to configure a default deployment model for the namespace legacy-apps.

Which configuration applies the pull secret automatically to all Pods launched by the standard default ServiceAccount in that namespace?

32. A Cloud Administrator is planning the Storage Class architecture for a multi-tenant TKG environment.

Each tenant requires:

1. Gold : SSD, High Performance, Deduplication Enabled.

2. Silver : HDD/Hybrid, Low Cost, RAID-5.

How is this mapped in vSphere with Tanzu?

33. A VKS Administrator is troubleshooting a TKG cluster provisioned with the name analytics-cluster. The provisioning process has stalled.

The administrator runs kubectl get tanzukubernetescluster analytics-cluster -n data-science -o yaml and observes the following status condition:
