ISC2 CC Business Continuity, DR & Incident Response Practice Question
Which statement best describes a warm site in disaster recovery?
⚠ Common exam trap
ISC2 often tests the distinction between warm and hot sites by making candidates confuse 'pre-installed hardware' (warm) with 'real-time data synchronization' (hot), so the trap is assuming that any site with hardware must also have live data.

Correct answer & explanation
✓
It has hardware and network equipment but requires data restoration from backups
A warm site is a middle-ground disaster recovery option that has hardware and network infrastructure pre-installed but does not have live, synchronized data. Instead, data must be restored from backups (e.g., tape or disk snapshots) before operations can resume. This contrasts with a hot site, which maintains real-time data replication and fully active systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It has replicated data but no active systems
Why it's wrong here
Replicated data suggests real-time sync, which is hot; warm site typically requires data restore.
- ✗
It is fully operational with real-time data synchronization
Why it's wrong here
That is a hot site.
- ✓
It has hardware and network equipment but requires data restoration from backups
Why this is correct
Warm site has equipment but not live data, so restore is needed.
- ✗
It has no hardware or infrastructure installed
Why it's wrong here
That describes a cold site.
