   What does OneFS's global namespace provide to clients?

   • AA single, unified file system view across all nodes in the cluster
   • BA virtualized view that hides the underlying file system
   • CA read-only snapshot of the entire cluster
   • DA separate file system view for each node in the cluster

   Which statement correctly contrasts scale-up and scale-out storage architectures?

   • AScale-up increases capacity or performance within a single system, while scale-out adds more independent systems to a cluster.
   • BScale-up adds more nodes to a cluster, while scale-out adds capacity to an existing node.
   • CScale-up is used only for performance, while scale-out is used only for capacity.
   • DScale-up and scale-out are identical approaches that both add nodes to a cluster.

   A video-editing studio runs a 4-node PowerScale cluster and is experiencing slow performance during peak rendering hours. The studio's workload is CPU-intensive and generates high I/O throughput. The budget allows for adding hardware, but the studio cannot afford to replace the entire cluster. Which action will most directly address the performance bottleneck?

   • AIncrease the protection level from N+1 to N+2 to improve performance
   • BAdd two more nodes to the cluster to increase both CPU and I/O capacity
   • CReplace all HDD nodes with all-flash nodes in a single maintenance window
   • DConfigure the cluster to use a single large storage pool for all data

   A company is comparing a traditional scale-up NAS with a PowerScale scale-out cluster for a growing engineering workload. The workload requires both increasing capacity and increasing throughput over time. Which advantage does the scale-out architecture provide over scale-up in this scenario?

   • AScale-out provides a single namespace, while scale-up requires multiple namespaces
   • BScale-out eliminates the need for data protection, while scale-up requires RAID
   • CAdding nodes increases both capacity and aggregate throughput, whereas scale-up typically increases capacity but not proportionally the file-serving performance
   • DScale-out requires fewer nodes to achieve the same capacity as scale-up

   A financial firm runs a 5-node PowerScale cluster with a protection level of N+2. One node fails completely during business hours. Which statement describes the cluster's behavior while the failed node is being replaced?

   • AThe cluster remains available, and data that was on the failed node is reconstructed from parity and mirrored data across the remaining nodes
   • BThe cluster becomes read-only until the failed node is replaced
   • CThe cluster fails over to a secondary cluster that was configured for replication
   • DThe cluster continues to operate, but only data with a replication factor of 2 is available
