   A VxRail administrator is planning to migrate an existing vSAN OSA cluster to vSAN ESA. Which statement correctly describes a key interoperability constraint that must be considered during this migration?

   • AAn existing OSA cluster can be upgraded to ESA in place by simply changing the vSAN cluster configuration, without any hardware changes.
   • BMigration from OSA to ESA can be performed by adding ESA nodes to the existing cluster and then removing OSA nodes one at a time.
   • CThe OSA cluster must be fully evacuated before any node can be converted to ESA, and mixed OSA/ESA nodes are not supported within the same cluster.
   • DMixed clusters containing both OSA and ESA nodes are supported during migration, as long as all nodes are from the same VxRail model.

   In vSAN ESA, what is the purpose of the stripe width in a storage policy?

   • ATo specify the encryption algorithm used for data at rest
   • BTo distribute data across multiple drives to improve performance
   • CTo define the number of copies of the data for redundancy
   • DTo determine the compression ratio for data reduction

   Which of the following is a benefit of deduplication and compression in vSAN ESA?

   • AThey reduce the number of NVMe drives required for cache
   • BThey increase the usable capacity of the cluster
   • CThey eliminate the need for storage policies
   • DThey improve the fault tolerance of the cluster

   A DevOps team is deploying a containerized application on vSAN ESA. The application requires high availability and uses snapshots for development testing. The team wants to ensure that snapshots do not consume excessive storage. Which storage policy setting should be used?

   • ASet FTT=0 to reduce storage overhead and rely on application-level snapshots.
   • BDisable snapshots because they are not supported in ESA.
   • CSet FTT=2 to ensure snapshots are protected, but this will increase storage usage.
   • DSet FTT=1 and enable space-efficient snapshots.
