   In the PowerScale filesystem, what is the primary purpose of block pointers stored in an inode?

   • ATo locate the data blocks that contain the file's content
   • BTo track the number of hard links to the file
   • CTo store the file's access control list (ACL)
   • DTo identify the node that owns the file

   A financial trading firm is deploying PowerScale for a mission-critical application that requires extremely high consistency. They are evaluating the trade-offs between journaling and filesystem checks. They want to minimize the risk of data loss while also minimizing downtime. Which approach best balances these requirements?

   • AEnable journaling but disable fsck to avoid any performance impact.
   • BEnable journaling and schedule regular fsck checks during maintenance windows.
   • CUse snapshots as the primary consistency mechanism instead of journaling.
   • DDisable journaling to reduce overhead and rely on periodic fsck checks.

   A hospital IT team is planning to use PowerScale for storing patient imaging data. They are concerned about data integrity in the event of a sudden power loss. They want to ensure that the filesystem can recover to a consistent state without manual intervention. Which feature of the PowerScale filesystem directly addresses this concern?

   • ACopy-on-write, which prevents data corruption by never overwriting existing blocks.
   • BJournaling, which records metadata changes before they are committed to the main filesystem.
   • CSnapshots, which create point-in-time copies of the filesystem for recovery.
   • DAutomatic fsck, which runs on every boot to repair any inconsistencies.

   A PowerScale administrator notices that a filesystem check is taking a long time to complete. They want to understand why the check is slow and what can be done to speed it up in the future. Which factor most likely contributes to the slow check?

   • AThe filesystem is using snapshots, which must be checked individually.
   • BThe cluster has too many nodes, causing fsck to run on each node sequentially.
   • CThe filesystem has a large number of small files, which increases the number of inodes to check.
   • DThe filesystem is using a journal, which adds overhead to the check.

   When a file grows too large for its direct block pointers, how does the PowerScale filesystem typically handle the additional data blocks?

   • AIt creates a new inode for the additional data.
   • BIt uses indirect blocks that contain pointers to additional data blocks.
   • CIt stores the extra data in the inode itself.
   • DIt compresses the existing data to make room.
