Which SANtricity feature should you recommend to tolerate two drive failures per pool and reduce rebuild times?

Explanation:
Dynamic Disk Pools (DDP) distributes data and parity across all disks in a pool rather than within fixed RAID groups. This arrangement lets the system tolerate multiple disk failures within the pool (two it can handle) and, when a failure occurs, rebuilds can be performed in parallel across many drives, which dramatically reduces rebuild times. RAID 5 can only tolerate a single drive failure, and RAID 6, while it tolerates two failures, rebuilds data within fixed RAID groups and doesn’t offer the same pool-wide parallel rebuild advantages as DDP. SnapMirror Sync is for synchronous replication between sites and doesn’t affect local drive fault tolerance or rebuild performance.
