Explanation

Once FLR (File Level Retention) is enabled on a file system, it is a permanent, irreversible state - this is by design to ensure regulatory compliance (WORM storage). Disabling it would undermine the entire purpose of immutable retention, so storage vendors intentionally make it a one-way operation.

Why the distractors are wrong:

  • A is incorrect - the auto lock can be modified (e.g., the default retention period can be adjusted after enablement).
  • B is incorrect - the compliance clock cannot be changed; it is tamper-proof to prevent backdating, so this is actually a true restriction, but it's a property of the clock, not a characteristic introduced "once FLR is enabled."
  • D is incorrect - auto delete settings can be modified within the bounds of the retention policy.

Memory tip: Think of FLR like pouring concrete - once it sets, you can adjust the surface (auto lock, auto delete), but you cannot un-pour it. "Lock in compliance, lock in FLR."
