An administrator reports that after rebooting one host in a vSAN cluster configured with Data-at-Rest Encryption using an external Key Management Server (KMS), the host shows all vSAN disk groups as unmounted.
The KMS is online and reachable from all hosts.
In vCenter, the host displays the following event:
"Failed to retrieve encryption key from KMS."
Key ID:
All other hosts in the cluster remain healthy and show "Encryption: Enabled." Why did the encryption key retrieval fail for this host?

After a planned power outage, an administrator decided to restart the vSAN cluster manually.
Drag and drop the three correct options from the Options list on the left and place them into the Required Options on the right in any order. (Choose three.)

Explanation:
Run the Python reboot helper script only on one ESXi host to recover the cluster.
Enable cluster member updates from vCenter Server on all ESXi hosts.
Exit all hosts from maintenance mode.
During a manual vSAN cluster restart after a planned outage, the hosts must first be brought back and exited from maintenance mode so the cluster can begin recovery. The vSAN reboot helper recovery script must then be run on only one ESXi host. Running the script on multiple hosts can create race conditions and unexpected cluster state. After the recovery script completes, cluster member updates from vCenter Server must be enabled on all ESXi hosts so that normal membership updates resume across the cluster. Enabling updates on only one host is incomplete because all hosts must return to normal cluster-member update behavior. Running the Python reboot helper script on all ESXi hosts is explicitly incorrect because the recovery operation must be initiated from a single host only. Disabling cluster member updates is a shutdown-side activity, not the required restart-side recovery action in this question.

A storage architect has been called into a meeting with the accounting team who is trying to determine why
20% of their raw capacity is not available for consumption. Their vSAN cluster was created with the following characteristics:
* 2 x 2 TB NVMe disks in 6 hosts in their vSAN cluster.
* FTT=1, RAID-1 for the default policy.
* Host Rebuild Reserve not activated for this cluster.
Which two items should the Architect say accounts for most of the unusable capacity? (Choose two.)

The security team has notified the VMware Cloud Foundation (VCF) Storage Administrator of a new security vulnerability that must be patched immediately. The vSAN Cluster uses vSphere Lifecycle Manager images.
After updating the image with the patch, what method should the administrator use to apply this patch with the least amount of disruption to the cluster?

An architect is describing the for a client which storage platforms are supported in which types of Domains for automated installation in VMware Cloud Foundation (VCF) Private Clouds.
Drag and drop the Support Status of each storage model on the left to each type of Workload Domain on the right.
Drag and drop the Support Status of each storage model on the left to each type of Workload Domain on the right.
정답:
Explanation:
The correct mapping comes from the VCF 9.0 Principal and Supplemental Storage model. vSAN ESA is supported as principal storage for the Management Domain default cluster, Management Domain additional clusters, and VI Workload Domains. A vSAN Storage Cluster is not supported for the Management Domain default cluster because the initial management cluster requires a standard principal storage model, but it is supported as principal storage for Management Domain additional clusters and VI Workload Domains. Fibre Channel is supported as both principal and supplemental storage across all three domain or cluster categories, allowing either initial cluster creation or later datastore expansion. NFS v4.1 is supplemental-only across these categories. NFS can be principal only when using NFS v3; NFS v4.1 is used as supplemental storage after the domain or cluster exists. These statuses align with VCF's distinction between principal storage, which is used during workload domain or cluster creation, and supplemental storage, which is added after creation for workloads or data-at-rest use cases.
