   A VxRail cluster is being designed with 4 nodes, each with 1 disk group containing 1 cache SSD and 4 capacity SSDs. The storage architect wants to use RAID-5 for a VM. What is the minimum number of nodes that must be available for the VM to remain accessible if 1 node fails?

   • A4 nodes
   • B2 nodes
   • C1 node
   • D3 nodes

   In a vSAN stretched cluster, what is the role of the witness host?

   • AIt accelerates performance by caching data from both sites.
   • BIt provides quorum and helps avoid split-brain scenarios.
   • CIt stores a full copy of all VM data.
   • DIt acts as a backup for the vCenter Server.

   A VxRail cluster is being configured for a financial services customer. The security team requires data-at-rest encryption, and the storage team wants to enable deduplication and compression to save capacity. The cluster uses all-flash storage. What is the correct approach to meet both requirements?

   • AEnable vSAN encryption only, as deduplication and compression cannot be used with encryption
   • BUse self-encrypting drives (SEDs) instead of vSAN encryption
   • CEnable vSAN encryption and then enable deduplication and compression
   • DEnable deduplication and compression, then enable vSAN encryption

   A VxRail cluster is running a database workload with high write I/O. The storage administrator enabled deduplication and compression to save capacity. After enabling, the administrator notices increased write latency. What is the most likely cause of the performance degradation?

   • AThe cache tier is too small for the workload
   • BDeduplication and compression add CPU overhead on the hosts, increasing write latency
   • CThe network is congested
   • DThe storage policy is set to RAID-6

   What is the primary purpose of vSAN encryption in a VxRail cluster?

   • ATo prevent ransomware attacks on VMs.
   • BTo encrypt data in transit between hosts.
   • CTo protect data at rest from unauthorized access.
   • DTo improve the performance of the vSAN datastore.
