In a VxRail cluster, what is the primary purpose of enabling deduplication and compression on the storage layer?

To increase the number of VMs that can run concurrently on the cluster

To improve the performance of all I/O operations by reducing latency

To encrypt data at rest to meet security compliance requirements

To reduce the amount of physical storage capacity required to store the same logical data

A VxRail cluster runs a critical OLTP database. The storage administrator wants to enable deduplication and compression to save space. The database has a high write rate. What is the likely impact on the database?

Reduced memory usage, improving database cache efficiency.

Improved performance because the database will have more free space.

Increased write latency due to the CPU overhead of deduplication and compression.

No impact, since deduplication and compression are transparent to the database.
