A drive in a VSP One B24 system is configured in a Dynamic Drive Protection (DDP) group. If this drive gets blocked as a result of a failure which process automatically starts to keep the DDP…

Question

Options

• ACorrection Copy with spare drive
• BCorrection Copy with spare areas on drives
• CDynamic Sparing with spare areas on drives
• DDynamic Sparing with spare drive

• A

• B

• C
  69% (27)
• D
  8% (3)

Explanation

In a DDP group, spare capacity is not held on a dedicated spare drive but is instead distributed as spare areas across all drives in the group. When a drive is blocked due to failure, Dynamic Sparing is the automatic process that rebuilds redundancy by redistributing the lost data into those pre-allocated spare areas across the remaining drives - making C the only combination that matches both the correct process name and the correct spare type.

Why the distractors are wrong:

• A & B (Correction Copy): Correction Copy is triggered by media errors (surface defects detected during background verification), not by a drive being blocked. It's a proactive copy process, not a failure-recovery process.
• A & D (spare drive): DDP does not use a dedicated hot-spare drive. That is a traditional RAID concept. DDP's redundancy model relies on distributed spare areas, making any "spare drive" answer wrong in a DDP context.

Memory tip: Link the word "Dynamic" - Dynamic Drive Protection uses Dynamic Sparing. Both words share "Dynamic" because the spare space itself is dynamically spread across all drives, not sitting idle on one dedicated spare. If you see "Correction Copy" + drive failure, it's a mismatch - Correction Copy fixes media, not missing drives.
