   A storage architect is comparing SnapshotIQ's Copy-on-Write (CoW) with a theoretical Redirect-on-Write (RoW) implementation for a PowerScale cluster. The workload is write-heavy with frequent small updates to large files. Which statement accurately reflects a trade-off between CoW and RoW?

   • ACoW requires copying original blocks before each write, which can add latency to write operations.
   • BCoW is always faster for write-heavy workloads because it avoids redirecting writes.
   • CRoW requires copying original blocks before each write, which can add latency to write operations.
   • DRoW and CoW have identical performance characteristics for all workloads.

   An administrator wants to create a SnapshotIQ schedule that takes a snapshot every night at 2:00 AM and retains it for 7 days. Which two settings must be configured in the schedule?

   • AReplication target and bandwidth limit
   • BAlias name and snapshot size limit
   • CFrequency (daily at 2:00 AM) and retention (7 days)
   • DFileset path and access control list

   A system administrator wants to use SnapshotIQ to protect a critical directory from accidental file deletion. They create a snapshot and then a user deletes a file. How can the administrator restore the deleted file?

   • AUse the snapshot to recover the file by copying it back from the snapshot to the original location.
   • BThe snapshot automatically restores the file because it is a continuous data protection feature.
   • CThe file is not recoverable because snapshots only protect against corruption, not deletion.
   • DThe administrator must recreate the file manually because snapshots are not accessible to users.

   In SnapshotIQ's Redirect-on-Write (RoW) mechanism, what happens to the original data block when a new write modifies data that is part of a snapshot?

   • AThe snapshot is updated to point to the new block, and the original block is freed.
   • BThe new write is placed in a new block, and the original block is left intact for the snapshot.
   • CThe original block is deleted, and the snapshot points to the new block.
   • DThe original block is copied to a new location, and the write modifies the original block.

   What happens to a snapshot when its retention period expires in SnapshotIQ?

   • AIt is moved to the .snapshot directory for manual deletion.
   • BIt is converted into a permanent snapshot.
   • CIt is replicated to a remote cluster for archival.
   • DIt is automatically deleted, and its space is reclaimed.
