CV0-004 Practice Question: An e-commerce company is deploying a disaster…
An e-commerce company is deploying a disaster recovery solution across two cloud regions. The primary region runs the production workload. The recovery region should have a fully provisioned environment that can take over immediately in case of a failure. Which deployment strategy BEST meets this requirement while minimizing costs?
⚠ Common exam trap
It's easy for candidates to confuse 'pilot light' with 'warm standby'—pilot light has minimal core services running but requires manual scaling and provisioning of the full stack, whereas warm standby has a fully provisioned (though scaled-down) environment ready to take over instantly.
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
✓
Warm standby in the recovery region
Warm standby is the correct strategy because it maintains a fully provisioned, scaled-down copy of the production environment in the recovery region that can be activated immediately upon failover. This meets the requirement for immediate takeover while minimizing costs by running only the essential resources (e.g., a minimal number of compute instances, a standby database) instead of a full active-active deployment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Backup and restore to the recovery region upon failure
Why it's wrong here
Backup and restore is a cold strategy, not immediate.
- ✗
Multi-site active-active with load balancers
Why it's wrong here
Active-active is the most expensive option because both regions handle traffic continuously.
- ✗
Pilot light with minimal resources running in recovery
Why it's wrong here
Pilot light is not fully provisioned; it requires provisioning resources at failover, which is not immediate.
- ✓
Warm standby in the recovery region
Why this is correct
Warm standby has a fully provisioned but potentially smaller environment that can be scaled up quickly for failover.
