   A PowerScale cluster uses Reed-Solomon protection with a +3n level. A node fails completely. How does the cluster recover the data that was stored on the failed node?

   • AIt automatically restores the data from a snapshot taken before the failure.
   • BIt uses parity blocks distributed across the remaining nodes to reconstruct the missing data.
   • CIt marks the data as lost and requires manual intervention to restore it.
   • DIt reads a full replica of the data from a backup system.

   A PowerScale cluster has 5 nodes, each with 10 drives. The administrator notices that a large file is striped across all nodes and drives. What is the primary benefit of this file striping approach?

   • AIt improves performance by allowing parallel reads and writes across multiple nodes and drives.
   • BIt ensures that all data is stored on a single node for faster access.
   • CIt simplifies data recovery by keeping all blocks of a file on one drive.
   • DIt reduces the need for parity data by storing multiple copies of each block.

   A media company stores large video files on a PowerScale cluster. The files are append-heavy and rarely modified. The storage administrator wants to maximize usable capacity while still protecting against a single node failure. Which FEC protection level should be configured?

   • A+2d:1n
   • B+1n
   • C+3n
   • D+2d:1n:1c
