   What is the primary purpose of journaling in the PowerScale filesystem?

   • ATo record changes before they are applied, enabling recovery after a crash or power failure.
   • BTo compress file data to save storage space.
   • CTo encrypt file metadata for security.
   • DTo store a complete copy of all file data for backup purposes.

   A company is designing a PowerScale cluster for a high-throughput analytics workload. They plan to start with 4 nodes and expect to grow to 16 nodes over time. They need to ensure that the filesystem can handle the growth without requiring a redesign. Which feature of the PowerScale filesystem supports this growth?

   • AThe filesystem limits the number of nodes to 8 for performance reasons.
   • BThe filesystem requires manual reconfiguration of the namespace when nodes are added.
   • CThe filesystem uses a single global lock manager that must be upgraded as the cluster grows.
   • DThe filesystem automatically redistributes data and metadata as nodes are added.

   A video editing company stores large 4K video files on a PowerScale cluster. They notice that as files grow, the filesystem performance remains consistent. They want to understand how the filesystem manages the allocation of data blocks for these large files. Which statement best describes the block allocation strategy?

   • ABlocks are allocated from a single node to keep the file local.
   • BBlocks are allocated contiguously to maximize sequential read performance.
   • CBlocks are allocated dynamically across the cluster, and the inode tracks them via block pointers.
   • DBlocks are allocated in fixed-size extents and the inode stores the extent list.

   A media streaming company is designing a PowerScale cluster to serve video content to millions of users. They expect read-heavy workloads with occasional writes. They are considering starting with a small cluster and scaling out as demand grows. They want to ensure that the filesystem can handle the scaling without performance degradation. Which factor is most critical to ensure successful scaling?

   • AEnsuring that the cluster uses a centralized metadata server to manage the namespace.
   • BEnsuring that all data is replicated to every node for high availability.
   • CEnsuring that the cluster has enough network bandwidth to handle the increased traffic.
   • DEnsuring that the filesystem automatically rebalances data and metadata as nodes are added.

   Which mechanism does PowerScale use to proactively detect and correct data corruption in the filesystem?

   • AA backup of the entire filesystem stored on a separate cluster.
   • BA scheduled defragmentation process that rewrites all data.
   • CA full filesystem scan performed every time the system boots.
   • DChecksums stored with data blocks, which are verified during reads and corrected from parity or replicas.
