   A company's PowerScale cluster has 8 nodes. A storage administrator notices that a single file is being accessed by hundreds of clients simultaneously. How does OneFS handle this workload to avoid overloading a single node?

   • AThe file's data and metadata are distributed across multiple nodes, and client requests are served by the node that holds the relevant data blocks
   • BThe cluster creates a temporary copy of the file on a dedicated cache node for the duration of the high-access period
   • CThe file is replicated to all nodes, and each client is assigned a random node to serve the request
   • DThe file is locked to the node where it was first created, and all clients must access it through that node

   A university research lab has a 6-node PowerScale cluster. Faculty members access files using a single mount point, and they are unaware of which physical node stores their data. The lab is adding two more nodes to increase capacity. After the addition, which behavior will the faculty observe?

   • AThey will see the same mount point, and OneFS will automatically redistribute data across the new nodes
   • BThey will experience a brief outage while the cluster rebuilds the namespace
   • CThey must remount the share to access files on the new nodes
   • DThey will see a second mount point for the new nodes' capacity

   A company runs a 6-node PowerScale cluster with N+2 protection. A node fails and is not replaced for several days. During this time, the cluster experiences a second node failure. Which statement accurately describes the cluster's state and the data-protection implications?

   • AThe cluster is still available, but it is now running with zero fault tolerance; any additional node failure will cause data unavailability
   • BThe cluster has lost data because two nodes failed before the first was replaced
   • CThe cluster will fail over to a secondary cluster to maintain availability
   • DThe cluster will automatically rebuild data to the remaining nodes to restore N+2 protection

   A company has a 3-node PowerScale cluster that is 80% full. The storage team is adding a 4th node to increase capacity. After the node is added and the cluster begins rebalancing, what will users experience?

   • AA requirement to remount the share to see the new capacity
   • BA brief outage while the cluster restarts to incorporate the new node
   • CA temporary reduction in available capacity while data is moved to the new node
   • DNo disruption to file access, and the new node's capacity becomes available as data is redistributed
