   A media company's NAS environment currently consists of two standalone file servers, each with 24 TB of usable capacity. The environment is nearing capacity, and the company expects storage needs to grow by roughly 20% per year for the next five years. The IT manager wants a solution that adds capacity and performance incrementally as the company grows, without requiring a forklift upgrade or downtime when expanding. Which architecture should the solution use?

   • AA two-node failover cluster of file servers where each server is replaced with a larger model every three years
   • BA SAN with a dedicated storage array that is expanded by adding new disk shelves to the existing controller
   • CA scale-up NAS where each file server is upgraded with larger drives and additional controllers as needed
   • DA scale-out NAS cluster where additional nodes are added to a single cluster to increase both capacity and performance

   How does OneFS unify the cluster's nodes into a single file system?

   • ABy distributing file system metadata and data across all nodes in the cluster
   • BBy using a network file system protocol to aggregate node storage
   • CBy using a central metadata server to coordinate all file operations
   • DBy creating a separate file system on each node and mounting them together

   A company runs a 4-node PowerScale cluster with N+2 protection. The company is considering a disaster-recovery strategy and wants to ensure that data can be recovered if the entire cluster is lost. Which mechanism should they configure?

   • AIncrease the protection level to N+3 to protect against site loss
   • BConfigure the cluster to use erasure coding with a higher stripe width
   • CEnable SmartQuotas to limit data loss in the event of a failure
   • DSyncIQ replication to a second PowerScale cluster at a remote site

   What is the primary purpose of the back-end network in a PowerScale cluster?

   • ATo provide out-of-band management access to each node's BMC
   • BTo connect the cluster to client systems over Ethernet or Fibre Channel
   • CTo connect the cluster to external cloud storage for tiering
   • DTo enable high-speed inter-node communication for data replication and cluster operations

   A company runs a 6-node PowerScale cluster with N+2 protection. During a maintenance window, a technician accidentally powers off two nodes simultaneously. The cluster remains online, but the storage team notices that the cluster is running in a degraded state. What is the most immediate risk to data availability, and what should the team do first?

   • AThe cluster will fail over to a remote replication target to maintain availability
   • BThe cluster can tolerate the two-node failure, but a third node failure would cause data unavailability; the team should power the nodes back on as soon as possible
   • CThe cluster has already lost data because two nodes failed simultaneously; the team should restore from backup
   • DThe cluster will automatically rebuild data to the remaining nodes, and the team should do nothing
