A storage administrator is asked to provision storage on an E-Series system. Which disk layout type provides the fastest rebuild time after disk failure?
Correct Answer: A
= Dynamic Disk Pools (DDP) is a disk layout type that provides the fastest rebuild time after disk failure on an E-Series system. DDP distributes data, parity, and spare capacity across a pool of disks, instead of using dedicated parity and spare disks. This enables faster and more efficient reconstruction of data in the event of a disk failure, as well as better performance and load balancing. DDP also reduces the risk of data loss due to multiple disk failures, as it can tolerate any number of disk failures up to the pool's protection level.
