VMware Updated 5V0-22.21 Exam Questions and Answers by azalea

According to the VMware official documentation, vSAN with SNA is the recommended configuration for the vSAN Data Persistence platform (vDPp). This configuration provides support for high availability [1], scalability, and enterprise-grade security. With SNA, the entire vSAN cluster is connected over a single high-speed network, and each node has direct access to the shared storage. This ensures that workloads are balanced across the cluster, which in turn improves performance and reliability. Additionally, SNA ensures that storage is accessible to all nodes in the cluster, eliminating the need for any centralized storage controllers.

An all-flash vSAN cluster contains a sufficient number of capacity devices and cache devices to support different RAID levels.

FTT=3(RAID-1 Mirroring) - This policy requires at least 4 capacity devices, where each object is mirrored across three copies of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=1 (RAID-1 Mirroring) - This policy requires at least 2 capacity devices, where each object is mirrored across one copy of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=2 (RAID-6 Erasure Coding) - This policy requires at least 6 capacity devices, where each object is striped across two sets of parity and data. This cannot be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=1 (RAID-5 Erasure Coding) - vSAN does not support RAID-5 Erasure coding.
