   A company has a 5-node PowerScale cluster with a mix of HDD and SSD nodes. The storage team wants to ensure that a critical database file is always available even if two nodes fail. The file is currently stored with a protection level of N+1. Which action will meet the availability requirement while minimizing capacity overhead?

   • AManually copy the file to two different nodes in the cluster
   • BChange the cluster-wide protection level to N+2
   • CApply a SmartPools policy to place the file on SSD nodes with a protection level of N+2
   • DEnable SyncIQ replication to a second cluster for the file

   What is the purpose of failover in a PowerScale cluster?

   • ATo encrypt data at rest to protect against unauthorized access
   • BTo distribute data evenly across all nodes for performance
   • CTo maintain data availability by redirecting client access to healthy nodes after a failure
   • DTo create a backup copy of data on a remote cluster

   A company is designing a new PowerScale cluster for a general-purpose file workload. The team has selected 6 nodes, each with 8 drives. They want to organize the nodes into storage pools so that performance-sensitive data is on faster nodes and archival data is on slower nodes. Which approach should they use?

   • ACreate one storage pool with all nodes and rely on the cluster to automatically tier data to faster drives
   • BCreate two storage pools: one with the faster nodes and one with the slower nodes, then assign data to each pool using SmartPools policies
   • CAssign each node to its own storage pool to maximize flexibility
   • DUse a single storage pool and manually move files to specific nodes as needed

   A government agency uses a 3-node PowerScale cluster with N+1 protection. The agency is planning a maintenance window to upgrade the firmware on all nodes. The upgrade requires each node to be rebooted one at a time. What is the maximum number of nodes that can be offline simultaneously during the upgrade without risking data availability?

   • AThree nodes
   • BZero nodes
   • CTwo nodes
   • DOne node
