SK0-005 security-disaster-recovery Practice Question
Exhibit
Task | Duration (minutes) ----------------------------------------------- Provision virtual machines | 60 Restore database from backup | 120 Application validation | 60 ----------------------------------------------- Total RTO | 240
Refer to the exhibit. A disaster recovery test reveals the following timeline for a critical application. The business requires an RTO of 2 hours. Which of the following actions would MOST effectively reduce the RTO to meet the requirement?
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
✓
Implement database replication to eliminate the database restore time.
Option A is correct because the database restore takes 120 minutes—the largest portion of the RTO. Replication would make the database continuously available, reducing that time to near zero and bringing total RTO to about 120 minutes (provisioning + validation) which meets the 2-hour target. Option B could reduce VM provisioning time but not address the database restore. Option C reduces validation by 30 minutes, not enough. Option D does not significantly impact VM provisioning time, which is already only 60 minutes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement database replication to eliminate the database restore time.
Why this is correct
Database replication provides a near-zero restore time, directly reducing the largest RTO component and achieving the 2-hour target.
- ✗
Add more network bandwidth to speed up VM provisioning.
Why it's wrong here
VM provisioning already takes only 60 minutes; even if halved, the database restore still dominates and RTO remains above 2 hours.
- ✗
Use a warm site with pre-configured storage.
Why it's wrong here
A warm site may speed up provisioning slightly but does not address the 120-minute database restore bottleneck.
- ✗
Automate application validation to reduce that phase by half.
Why it's wrong here
Cutting validation from 60 to 30 minutes still leaves a total RTO of 210 minutes, exceeding the 2-hour requirement.
