Question 21

A Storage Administrator is performing post-migration health checks after upgrading a Workload Domain from vSAN OSA to vSAN ESA. The legacy OSA cluster heavily relied on Deduplication to meet capacity requirements.
The administrator pulls the vmkernel.log and observes the compression statistics for the ESA storage pool.
```
2026-11-20T10:15:22Z INFO vsan-lsom - Object 5543... enabling compression.
2026-11-20T10:15:35Z INFO vsan-dom - Write I/O (4KB) compressed to 1KB. Network transmit: 1KB.
2026-11-20T10:15:45Z INFO vsan-crypto - Encrypting 1KB payload.
2026-11-20T10:16:00Z INFO vsan-lsom - Storage Pool capacity update: Total logical written 100TB, Physical consumed 40TB.
```
The administrator is concerned that the loss of "Deduplication" in ESA will cause the cluster to run out of physical space.
How does the log data and the deep architectural fusion of ESA features resolve the administrator's concern? (Select all that apply.)

A.The log confirms the "Top-of-Stack" processing pipeline: Data is Compressed FIRST (4KB to 1KB), then Transmitted, then Encrypted. This ensures the network and encryption engines only process the minimized payload.

B.Because Deduplication is missing, the backend resync time during a host failure will increase significantly compared to OSA, as ESA must rebuild duplicate blocks.

C.The log proves that 100TB of logical data is only consuming 40TB of physical space (a 2.5x efficiency ratio) using ONLY compression, effectively replacing the legacy deduplication savings.

D.By eliminating the deduplication hash table lookups, ESA eliminates the primary cause of high backend latency, allowing the storage pool to sustain higher IOPS even as capacity fills up.

Question 22

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 vSAN Data Protection appliance was deployed to a non-vSAN datastore.

B.The vCenter Server user account was created locally on the VCSA Photon OS level.

C.The vCenter Server user account used for registration does not have the required permissions.

D.The appliance is using DHCP IP addresses for management.

E.The forward and reverse DNS resolution between the appliance and vCenter Server are not properly configured.

Question 23

An Infrastructure Manager is auditing the Storage Policy Based Management (SPBM) behavior for virtual machines running on an HCI Mesh Compute-Only Client cluster.
```
[root@esx-comp-01:~] esxcli vsan debug object list -u 5543...
Object UUID: 5543... (VM: Database-01)
Policy: FTT=1 (RAID-1), IOPS Limit: 2000
Component 1: ACTIVE (Host: esx-storage-05) -> Remote Server Cluster
Component 2: ACTIVE (Host: esx-storage-06) -> Remote Server Cluster
Witness: ACTIVE (Host: esx-storage-07) -> Remote Server Cluster
```
How do SPBM rules mechanically enforce storage protection and QoS when the VM compute (esx- comp-01) and storage backend (esx-storage-05/06) exist in completely different physical clusters? (Select all that apply.)

A.The SPBM engine on the Client host must duplicate the data (2x multiplier) across the network to satisfy the RAID-1 requirement, doubling ISL bandwidth.

B.If the network between the Client and Server cluster is severed, the VM on esx-comp-01 will continue running in read-only mode using local NVMe cache.

C.The "IOPS Limit" (QoS) rule is strictly enforced by the DOM Client module running on the *Client compute host* (esx-comp-01), throttling the DB I/O before it even hits the network.

D.The "Failures to Tolerate" (RAID-1) layout logic is strictly managed by the DOM Owner module on the *Remote Server cluster*, ensuring the components never reside in the same fault domain.

Question 24

A multinational corporation is deploying a VMware Cloud Foundation (VCF) Workload Domain cluster to host tier-1 business applications with the following requirements:
* Deliver high performance to all workloads.
* Integration with automated VM placement.
* Reuse of existing infrastructure including multiple Fibre Channel (FC) arrays partitioned by business unit.
* The storage architecture must avoid vSAN.
* Meet organizational separation requirements.
Which two deployment approaches meet these requirements? (Choose two.)

A.Configure dedicated VMFS datastores on assigned FC arrays as principal storage.

B.Configure dedicated VMFS datastores on assigned FC arrays as supplemental storage.

C.Configure a shared VMFS datastore on an assigned FC array as principal storage.

D.Configure shared VMFS datastores on an assigned FC array as supplemental storage.

E.Configure shared VMFS datastores on an assigned FC array as principal storage.

Question 25

A VCF Deployment Specialist is troubleshooting a complex partition in a vSAN ESA cluster. Following a vCenter restore from backup, the cluster split into 3 separate partition groups.
The specialist uses Ruby vSphere Console (RVC) to dump the CMMDS cluster table:
```
[RVC Output: vsan.cluster_info ~cluster]
Partition Group 1: esx-01 (Master), esx-02 (Backup), esx-03
Partition Group 2: esx-04 (Master)
Partition Group 3: esx-05 (Master), esx-06
[root@esx-04:~] vmkping -I vmk2 192.168.10.1 (esx-01) -s 8972 -d
Response: sendto() failed: Message too long
```
Based on the RVC topology and vmkping output, which TWO configurations are directly causing this cluster segmentation? (Choose 2.)

A.The ESXi hosts esx-04 through esx-06 lost connectivity to the vSAN Data-in-Transit (DiT) Key Management Server, breaking the secure network channels.

B.Network I/O Control (NIOC) is actively blocking the CMMDS traffic because the Shares are set to
"Low".

C.esx-04 is placed in "vSAN Witness" mode, which automatically isolates it from standard data partition groups.

D.An MTU mismatch exists on the physical switch ports for esx-04, esx-05, and esx-06; the vSAN network requires 9000 MTU end-to-end, and jumbo frames are being dropped.

E.The restored vCenter Server pushed an outdated Unicast Agent table to the hosts, causing desynchronization in the cluster membership lists.
