What is the function of the vSAN Witness appliance in a stretched VI Workload Domain?

  1. To store a third copy of virtual machine data for failure tolerance purposes
  2. To provide additional storage space for virtual machines
  3. To provide a network connection between the two data sites during a network outage
  4. To provide a third site for quorum purposes

Answer(s): D

Explanation:

In a stretched vSAN cluster within a VMware Cloud Foundation (VCF) VI Workload Domain, the vSAN

Witness appliance serves as a quorum mechanism. It is deployed as a third site to help the cluster determine which site should continue operating in the event of a network partition or site failure. This third "witness" site does not store actual data but maintains metadata to track the cluster's status, ensuring high availability and preventing data loss by enabling failover between the two primary data sites.
The vSAN Witness does not store a third copy of VM data, provide additional storage, or act as a network connection during outages.



An administrator is tasked with deploying a new VMware Cloud Foundation (VCF) 5.0 environment based on the consolidated VCF architecture model.

Which type of principal storage would the administrator configure for the environment?

  1. VMFS on FC Datastore
  2. vSAN Oriqinal Storaqe Architecture
  3. vSAN Express Storaqe Architecture
  4. vSAN Remote Datastore (HCI Mesh)

Answer(s): C

Explanation:

For VMware Cloud Foundation (VCF) 5.0 in a consolidated architecture model, vSAN Express Storage Architecture (ESA) is the recommended and supported principal storage option. vSAN ESA is optimized for performance and efficiency and is designed to work seamlessly within the consolidated model, where both management and workload domains share the same infrastructure.



An administrator was asked to ensure virtual machines running in a production workload domain are protected even against two simultaneous host failures in the cluster using vSAN storage.
Which storage policy parameter must be configured accordingly to satisfy this requirement?

  1. Erasure coding
  2. Full reservation
  3. Stripe width = 2
  4. Failures to tolerate = 2

Answer(s): D

Explanation:

In vSAN storage, the Failures to Tolerate (FTT) parameter in the storage policy determines the number of host or disk failures a virtual machine can withstand without data loss. Setting FTT = 2 ensures that the VM is protected even in the event of two simultaneous host failures by creating additional data replicas to meet this level of redundancy.



What is the minimum number of hosts required to support two failures using vSAN Erasure Coding?

  1. 6
  2. 3
  3. 4
  4. 5

Answer(s): A

Explanation:

To support two host failures with vSAN Erasure Coding, specifically using RAID-6 (4+2) Erasure Coding, a minimum of 6 hosts is required. RAID-6 allows data to tolerate two simultaneous failures by distributing parity data across the hosts, which provides fault tolerance with a lower storage overhead compared to mirroring.

3 hosts or 4 hosts would not support RAID-6 and would be limited to RAID-1 (mirroring) configurations. 5 hosts are also inadequate because RAID-6 requires at least 6 hosts to achieve the 4+2 configuration.
