During maintenance on hosts in a four-node vSAN cluster, a host is placed in maintenance mode with the
"Ensure Accessibility" option.
All VMs are running with the Default Storage Policy (RAID-1, FTT=1) which has not been modified from the default settings.
While one of the hosts in the cluster is down for firmware upgrade, a second host in the cluster loses network connectivity.
How will the cluster be affected?

• A. Some VMs become inaccessible until one of the affected hosts return to service.
• B. Data is permanently lost for affected objects.
• C. vSAN rebuilds missing components immediately on remaining hosts.
• D. All VMs remain accessible; vSAN automatically rebalances to the other hosts.

An administrator has been tasked with deploying vSAN Data Protection in a VMware Cloud Foundation (VCF) Workload Domain. The administrator deploys the VMware Live Recovery OVA and logs into the management interface to start the Configure Appliance process, but the appliance fails to register with vCenter.
What are two possible causes the administrator can check to resolve the issue? (Choose two.)

• A. The vCenter Server user account was created locally on the VCSA Photon OS level.
• B. The vSAN Data Protection appliance was deployed to a non-vSAN datastore.
• C. The forward and reverse DNS resolution between the appliance and vCenter Server are not properly configured.
• D. The vCenter Server user account used for registration does not have the required permissions.
• E. The appliance is using DHCP IP addresses for management.

An architect is designing a vSAN Original Storage Architecture (OSA) cluster for a VMware Cloud Foundation (VCF) Management Domain. The following details were made available:
* 12 hosts, each host with: 3 x 800 GB NVMe (cache) and 12 x 3.84 TB SAS SSD (capacity).
* Planned configuration: 3 disk groups per host (1 NVMe + 4 SSD each).
* Storage policy: FTT = 2 (RAID-1), Checksum. Deduplication and Compression are Enabled.
* Network: 25 GbE dedicated vSAN network fabric, properly configured for jumbo frames.
After deployment and loading test data to 70% capacity, the operations team reported extended resync times when two hosts are placed into maintenance mode with "Ensure Accessibility" selected and no hardware or network bottlenecks were detected.
How can the administrator explain the observed behavior?

• A. Deduplication and compression cause cache-tier contention during resync.
• B. With 3 disk groups per host, vSAN introduces additional metadata and resync operations under FTT = 2.
• C. "Ensure Accessibility" triggers a full component migration when FTT = 2, regardless of available quorum.
• D. NVMe devices in the cache tier limit backend de-staging throughput during resync.

An administrator has deployed a three-host vSphere cluster with a small amount of VMFS storage and wants to add additional capacity from a vSAN ESA cluster located in the same vCenter Server.
When the administrator selects the vSphere cluster and navigates to the Configure tab, the Datastore Management option is missing under the vSAN section.
What prerequisite must be met before the administrator can mount the remote datastore?

• A. The vSphere cluster must be deployed to a different VCF Workload Domain.
• B. The vSAN Storage cluster must have a minimum of 80% free space.
• C. vSAN must be enabled on the non-vSAN cluster to act as a compute cluster.
• D. A fourth host must be commissioned for the vSphere cluster.

Select the storage capabilities supported for use with persistent volumes in the VMware Kubernetes Service (VKS) in VMware Cloud Foundation (VCF).
Drag and drop the five supported capabilities from the vSphere Storage Capabilities list on the left and place them into the Supported Storage Capabilities list on the right in any order. (Choose five.)

Explanation:
Full Clone from Volume Snapshot
4kn Support
Online Volume Expansion
Offline Volume Expansion
Static Persistent Volume
VMware Kubernetes Service persistent volumes use vSphere storage integrations such as CNS and pvCSI to provide Kubernetes storage services backed by vSphere datastores and storage policies. The supported persistent volume capabilities include Static Persistent Volume, which allows pre-existing storage to be consumed by Kubernetes workloads; Offline Volume Expansion and Online Volume Expansion, which allow persistent volumes to be resized depending on workload and filesystem state; Full Clone from Volume Snapshot, which enables a new volume to be created from an existing snapshot; and 4kn Support, which supports modern 4K native storage devices where the underlying stack supports them. Storage vMotion with attached Persistent Volumes is not supported because moving an attached Kubernetes persistent volume while it is in active use can break attachment and consistency assumptions. Storage DRS is also not a supported persistent volume capability in this VKS context. Flash Read Cache is not part of the supported VKS persistent-volume capability set.
