ITPEC FE Subject A October 2024 — Question 11 of 60
Fail-Safe — when a failure occurs, the system transitions to a safe state to minimize damage.
Key concepts:
- •Fail-safe — system stops safely on failure, minimizing harm
- •Fool-proof — prevents user errors from causing problems
- •Fault-tolerant — system continues operating despite partial failures
- •Failover — system switches to a standby upon failure
Why not others:
- (a) describes fool-proof (protecting against user mistakes)
- (b) describes fault tolerance (maintaining function despite faults)
- (d) describes failover (switching to standby system)
Key rule: Fail-safe = safe shutdown on failure; fault-tolerant = keep running despite failure.
