Storage Class Memory (SCM) bridges the gap between DRAM and NAND flash memory. It offers faster access times than flash memory but is still slower than DRAM. SCM provides non-volatile storage with performance characteristics closer to DRAM, making it suitable for applications requiring high-speed data access.

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 C:Backup management (scheduling, policies) is also handled by the backup server.

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

Anincidentis anunplanned disruptionof a service or a reduction in its quality, often with anunknown root cause.

Incidents require immediate action to restore service.

Example: SAN switch port down, unexpected storage latency.

Support requestsare typically service requests, not incidents.

Impact actionsare more about changes, not incidents.

Events preventing correctionsmight be problems, not incidents.
