3V0-23.25 Exam Question 36

A VCF Architect is designing a site disaster recovery strategy for a retail client operating a vSAN Stretched Cluster.
The client's network team has imposed strict limitations on inter-site traffic, noting that the Inter- Site Link (ISL) occasionally drops packets under heavy load. The storage policy is configured with
"Dual Site Mirroring" and "Secondary FTT=1 (RAID-1)".
The architect is concerned about how a network partition (ISL failure) interacts with this storage policy regarding object accessibility and capacity planning.
Which of the following statements accurately describe the interaction between the network partition mechanics and the storage policy constraints? (Select all that apply.)

A.A flapping network partition on the ISL could trigger a "Witness bandwidth exhaustion" event if the cluster frequently splits and merges, causing metadata resync storms.

B.If a network partition isolates the Secondary site from both the Preferred site and the Witness, the Secondary site's replica components will transition to the 'Inaccessible' state.

C.The 'Secondary FTT=1 (RAID-1)' rule ensures that workloads on the isolated Secondary site can remain active by consuming the local replica copy without needing the Witness.

D.The Dual Site Mirroring policy implicitly relies on the Unicast agents maintaining connectivity to the Witness appliance to establish a quorum (>50% of votes) during an ISL failure.

3V0-23.25 Exam Question 37

Which architectural configuration strictly differentiates a vSAN 2-Node Direct-Connect cluster in a Remote Office/Branch Office (ROBO) environment from a standard 3-node vSAN deployment?

A.Standard 3-node clusters use traditional multicast Ethernet, whereas 2-Node Direct-Connect clusters require Fibre Channel crossovers to maintain synchronization.

B.The storage network traffic traverses direct crossover cables between the two local hosts, completely eliminating the requirement for a local 10/25 GbE top-of-rack storage switch.

C.2-Node Direct-Connect clusters are restricted to the Original Storage Architecture (OSA) because the Express Storage Architecture (ESA) log-structured filesystem requires a minimum of three physical hosts.

D.The 2-Node configuration requires the Witness Appliance to be installed locally on one of the edge servers, consuming valuable compute resources.

3V0-23.25 Exam Question 38

A Network Administrator executes a network validation check on a VCF cluster where Data-in- Transit (DiT) encryption was recently enabled to secure the physical storage VLAN.
The admin queries the vSAN network diagnostic output:
```
[root@esx-01:~] esxcli vsan network list
Interface: vmk2
Traffic Type: vsan
DiT Encryption Status: Enabled
MTU: 9000
Avg Frame Size: 8972 bytes
```
Which TWO statements accurately describe the impact of enabling DiT on the physical network transmission and MTU overheads? (Choose 2.)

A.DiT strictly encrypts the VMDK replication data (payload) but leaves the CMMDS (Cluster Monitoring, Membership, and Directory Service) metadata in cleartext to maintain split-brain detection speeds.

B.The use of Jumbo Frames (MTU 9000) is deprecated when DiT is enabled due to key buffer limitations; the interface must revert to MTU 1500.

C.DiT alters the standard TCP protocol, converting vSAN traffic into IPSec ESP (Encapsulating Security Payload) packets that require firewall modifications.

D.Using Jumbo Frames (MTU 9000) is highly recommended with DiT; larger frames mean fewer total packets to encrypt/decrypt, directly reducing the AES-NI CPU cycle consumption on the host.

E.DiT adds a cryptographic overhead to every packet (approximately 40 to 60 bytes for the AES- GCM tags and headers), meaning the maximum payload per frame slightly decreases.

3V0-23.25 Exam Question 39

An administrator is using an external Key Management Server (KMS) with a vSAN Data-at-Rest Encryption cluster.
The KMS becomes temporarily unavailable.
What happens if a host without a Trusted Platform Module in the cluster is rebooted during this outage?

A.The host starts in maintenance mode until it can communicate with the KMS.

B.The host fails to start because it cannot retrieve its encryption keys from the KMS.

C.The host starts, but all encrypted storage devices remain unmounted until the KMS becomes available.

D.The host starts normally using cached encryption keys and rejoins the vSAN cluster.

3V0-23.25 Exam Question 40

An Infrastructure Manager is utilizing the vSphere Lifecycle Manager (vLCM) in SDDC Manager to perform a firmware upgrade on the physical NVMe drives in a vSAN ESA cluster.
```
# vLCM Desired State Specification (JSON)
{
"esx_version": "8.0U2",
"vendor_addon": "DellEMC-OpenManage-v10",
"firmware_baseline": "Dell-NVMe-Gen4-v5.3.1"
}
```
How does vLCM natively handle the disruption of upgrading live NVMe firmware inside a running vSAN Express Storage Architecture cluster?

A.The firmware is upgraded directly from the physical Top-of-Rack network switches via Redfish protocol, bypassing the ESXi hypervisor entirely.

B.vLCM automatically copies all virtual machines to the remote vSphere Replication site before initiating the firmware flash to protect the data layer.

C.vLCM orchestrates the process by sequentially putting one host at a time into Maintenance Mode (using Ensure Accessibility), applying the new firmware payload via the Hardware Support Manager (HSM), and rebooting the host to initialize the NVMe controllers.

D.NVMe firmware upgrades are strictly "Hot-Add" and do not require ESXi host reboots or Maintenance Mode, allowing the drives to flash in the background without user intervention.
