Exam 3V0-23.25 Topic 1 Question 62 Discussion

Actual exam question for VMware's 3V0-23.25 exam
Question #: 62
Topic #: 1

An Operations Engineer is managing a Tanzu environment running on a vSAN Stretched Cluster.
A critical Kubernetes pod utilizing a 1 TB CNS Persistent Volume is running on Site-A.
```
[Storage Policy Rule View - CNS PVC]
Policy: K8s-Stretched-Gold
Site Disaster Tolerance:
Dual site mirroring
Failures to Tolerate: 1 (RAID-1)
CNS Volume ID: pvc-77bb...
```
A catastrophic power failure takes Site-A completely offline. The Witness and Site-B remain online. How does the deep integration between CNS, vSAN Stretched Cluster, and vSphere HA orchestrate the recovery of the Kubernetes persistent storage and the pod itself? (Select all that apply.)

A. CNS detects the site failure and automatically edits the Kubernetes manifest to dynamically re- mount the PVC to a different running worker node in Site B. B. vSphere HA automatically restarts the TKG Worker Node VM (which hosts the pod) on the surviving Site-B hosts. C. The Kubernetes Master Node must be manually instructed to perform a kubectl drain on the failed Site-A nodes before storage access is restored. D. The vSAN Distributed Object Manager detects the failure and instantly shifts the "Active" pointer for the FCD components to Site-B, maintaining storage accessibility. E. When the TKG Worker Node VM boots on Site-B, the vSphere CSI driver re-attaches the existing FCD to the worker node, and Kubernetes naturally restarts the pod using the intact data.
