   What is the primary role of the OneFS distributed file system in a PowerScale cluster?

   • AIt manages the cluster's virtual machine lifecycle
   • BIt provides block-level storage to external servers via iSCSI
   • CIt replicates data to a separate disaster recovery site in real time
   • DIt provides a single, unified file system namespace across all nodes in the cluster

   A PowerScale cluster is experiencing performance issues during a large data migration. The administrator suspects that the backend interconnect is saturated. Which type of traffic is most likely causing this saturation?

   • AClient read and write requests from the migration source
   • BManagement traffic from the web administration interface
   • CNode-to-node data replication and rebalancing traffic generated by the migration
   • DDNS queries from clients resolving the cluster's SmartConnect name

   A video-on-demand service is evaluating PowerScale to store its library of encoded video files. The primary requirement is to serve thousands of concurrent streaming requests with predictable low latency, while also storing the master copies of the content. Which architectural strength of PowerScale is most directly aligned with this requirement?

   • AThe reliance on external SAN storage for all persistent data
   • BThe ability to scale performance and capacity independently by adding nodes of different types to the same cluster
   • CThe use of a single centralized metadata server to coordinate all file operations
   • DThe requirement to use identical node types to maintain cluster performance consistency
