PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
A company is migrating to a new ERP system. The project manager needs to ensure minimal downtime during cutover. Which deployment strategy should be recommended?
⚠ Common exam trap
It's easy for candidates to confuse 'phased' with 'parallel,' assuming that rolling out in stages inherently minimizes downtime, but parallel deployment uniquely allows both systems to run simultaneously to eliminate cutover downtime entirely.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Parallel
The parallel deployment strategy is recommended because it allows the old and new ERP systems to run concurrently during cutover, enabling users to validate the new system while maintaining operations on the legacy system. This minimizes downtime by providing a fallback option if issues arise, ensuring business continuity during the migration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Big bang
Why it's wrong here
Big bang replaces the entire system at once, risking significant downtime if issues arise.
- ✗
Pilot
Why it's wrong here
Pilot is a trial for a limited user group, not a deployment strategy for the entire migration.
- ✓
Parallel
Why this is correct
Parallel operation runs both systems concurrently, allowing immediate switchback and minimal downtime.
- ✗
Phased
Why it's wrong here
Phased migration involves incremental cutovers, each potentially causing some downtime.
