A security administrator is tasked with increasing the availability of the storage networks while enhancing the performance of existing applications. Which of the following technologies should the…

LUN masking is a security control that restricts which hosts can access specific LUNs - it does not contribute to storage network availability or improve application performance.

Snapshots create point-in-time copies of volumes for backup and rapid recovery purposes but do not increase storage network availability or enhance ongoing application performance.

vSAN is a hypervisor-integrated storage virtualization technology that consolidates local disks but is not specifically targeted at increasing existing storage network availability or enhancing performance of already-running applications.

Dynamic disk pools distribute data, parity, and spare capacity across all drives simultaneously rather than using dedicated hot spares, which dramatically reduces rebuild times after a drive failure and spreads I/O load more evenly, directly improving both availability and performance.

Multipath I/O establishes redundant physical paths between servers and storage devices, eliminating single points of failure to increase availability while enabling load balancing across multiple active paths to enhance application throughput and performance.

Deduplication reduces the amount of stored data by eliminating redundant blocks, which conserves capacity but introduces processing overhead that can increase latency and degrade application performance.
