Cache miss (read miss):Data not in cache → fetched from the disk.

Astorage nodeis a component in a backup architecture that handles the actualdata movementduring the backup process:

Itorganizesthe backup data stream.

Itwritesthe data to the backup target (disk, tape, or cloud).

It does not manage policies or schedules (that’s the role of the backup server or management console).

Option A:Monitoring is done by the backup server or management tools.

Option D:Deduplication may be part of the process but is not theprimary roleof a storage node.

ACDP appliancesits in the data path and:

Intercepts all writesto the production volume.

Splits each write into two copies: one goes to the production volume, the other to the replica volume.

Maintains a journal for point-in-time recovery.

Option A/B/C: These are aspects of replication, but CDP’s primary function is real-time interception and splitting of writes.
