   A media company uses a PowerScale cluster to store large video files. They enable SnapshotIQ to protect against accidental deletion. An editor modifies a 10 GB file, and the snapshot must retain the original version. How does SnapshotIQ preserve the original data while minimizing space usage?

   • AThe original blocks are copied to the snapshot before the write is allowed to proceed.
   • BThe entire file is copied to the snapshot at the time the snapshot is created.
   • CThe new write is redirected to a new location, and the original blocks remain in place.
   • DThe snapshot stores only metadata pointers, and the original blocks are deleted after the write.

   Compared to Copy-on-Write (CoW), what is a key performance advantage of Redirect-on-Write (RoW) in SnapshotIQ?

   • ARoW allows snapshots to be created without any metadata overhead.
   • BRoW automatically deletes old snapshots to free space faster.
   • CRoW compresses data more effectively than CoW.
   • DRoW eliminates the need to copy the original block before every write to snapshot-protected data.

   In SnapshotIQ's Copy-on-Write (CoW) mechanism, what happens when a block that is part of an existing snapshot is about to be modified by a new write?

   • AThe snapshot is immediately deleted to free space for the new write.
   • BThe new write is redirected to a new block, and the original block remains untouched.
   • CThe write is blocked until the snapshot expires.
   • DThe original block is copied to a new location before the write proceeds, preserving the snapshot's view.

   A user accidentally deletes a critical file that was included in a SnapshotIQ snapshot taken earlier that day. What is the fastest way to recover the file?

   • AUse the 'undelete' command in the PowerScale CLI.
   • BBrowse the snapshot directory, locate the file, and copy it back to the original location.
   • CContact support to recover the file from the snapshot.
   • DRestore the entire snapshot to overwrite the current file system.
