ITPEC FE Morning April 2023 Question 58
ITPEC FE Morning April 2023 — Question 58 of 80
Fall back operation means disconnecting failed components so the system can continue performing its most critical functions — essentially operating in a degraded mode.
Why not others:
- (b) Describes rollback recovery (re-executing from a checkpoint), not rebooting (simply restarting the system)
- (c) Describes journaling/transaction logging but uses imprecise terminology — data logging in ITPEC context refers to general operational data recording
- (d) Describes backup (regularly saving files to another medium), not restoring (the process of recovering from a backup)
Key rule: Fall back operation = graceful degradation — keep essential functions running by shedding failed parts.
