PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A project to implement a new backup solution. Which THREE components are essential for a comprehensive backup strategy? (Choose three.)
⚠ Common exam trap
The PK0-005 exam often tests the distinction between 'essential components' (like retention policy, scheduling, and off-site storage) and 'optional enhancements' (like compression and replication), leading candidates to mistakenly include replication as a core requirement when it is actually a separate disaster recovery technique.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Retention policy
A retention policy is essential because it defines how long backup copies are kept, ensuring compliance with legal or operational requirements and enabling recovery to specific points in time. Without a retention policy, backups may be deleted too early (causing data loss) or retained indefinitely (wasting storage). It directly governs the lifecycle of backup data, which is a core component of any comprehensive backup strategy.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Retention policy
Why this is correct
A retention policy specifies how long backup data is kept to meet compliance and recovery needs.
- ✗
Compression
Why it's wrong here
Compression reduces storage space but is not a core component of a backup strategy.
- ✗
Replication
Why it's wrong here
Replication is used for real-time data mirroring, not traditional backup.
- ✓
Backup scheduling
Why this is correct
Scheduling ensures backups occur consistently and automatically.
- ✓
Off-site storage
Why this is correct
Off-site storage protects backups from physical disasters at the primary location.
