   In PowerScale, how does file striping distribute data across the cluster?

   • AData is divided into blocks that are spread across multiple nodes and drives.
   • BData is stored contiguously on a single drive to minimize seek time.
   • CData is compressed and stored on the node with the most free space.
   • DData is written to a single node and then replicated to all other nodes.

   What is the primary purpose of using a higher FEC protection level in PowerScale?

   • ATo increase the cluster's total storage capacity.
   • BTo provide greater tolerance against simultaneous node or drive failures.
   • CTo reduce the amount of storage required for parity data.
   • DTo improve read performance for small files.

   A PowerScale cluster has 6 nodes. The administrator needs to protect against the failure of two nodes simultaneously. Which FEC protection level should be configured?

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

   What is a key benefit of file striping in PowerScale?

   • AIt reduces the total amount of storage required for a file.
   • BIt ensures that all data is stored on a single high-performance node.
   • CIt allows multiple nodes to serve data from the same file simultaneously, improving throughput.
   • DIt eliminates the need for parity data in the protection scheme.

   A PowerScale cluster has 4 nodes. The administrator wants to ensure that a file can be read even if one node is offline. The file is striped across all nodes. How does the cluster ensure data availability during the node outage?

   • AThe cluster uses parity blocks to reconstruct the missing data from the offline node.
   • BThe cluster reads the file from a local cache on the remaining nodes.
   • CThe cluster waits for the node to come back online before serving the file.
   • DThe cluster serves the file from a backup copy stored on a separate system.
