Question 91 of 144
SK0-005 security-disaster-recovery Practice Question
A medium-sized company runs an e-commerce platform on a cluster of three physical servers hosting virtual machines. The disaster recovery plan includes daily backups to a remote data center using Veeam Backup & Replication. The company's annual disaster recovery drill is scheduled for next week. During the drill, the IT team plans to simulate a complete site failure by powering off the primary data center. The recovery time objective (RTO) is 4 hours, and the recovery point objective (RPO) is 1 hour. The team successfully restores the VMs at the remote site, but the application experiences significant performance degradation and many transactions fail due to database inconsistency. Investigation reveals that the backup was taken at 2:00 AM, but the failure occurred at 10:00 AM, and the application's database had transactions between 2:00 AM and 10:00 AM that were not captured. What should the IT team do to improve the recovery process?
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
✓
Enable log shipping with point-in-time recovery for the database.
The correct answer is B: Implement log shipping with point-in-time recovery for the database. The RPO of 1 hour is not being met because the backup schedule is daily. Option A is wrong because while a faster WAN can reduce backup time, the core issue is the backup frequency, not bandwidth. Option C is wrong because the issue is not data redundancy but recovery granularity; RAID protects against drive failure but not data loss from missing transactions. Option D is wrong because increasing RTO does not solve the RPO violation; the goal is to reduce data loss, not relax the time target.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure RAID 10 on all database servers to improve disk performance.
Why it's wrong here
RAID 10 improves disk I/O and fault tolerance but does not address the need for more frequent backups or point-in-time recovery.
- ✗
Upgrade the WAN connection between sites to reduce backup transfer times.
Why it's wrong here
A faster connection would not change the daily backup schedule. The RPO requires more frequent backups, not just faster ones.
- ✓
Enable log shipping with point-in-time recovery for the database.
Why this is correct
Log shipping allows transaction log backups to be taken frequently (e.g., every 15 minutes) and applied to the standby database, enabling recovery to any point in time, thus meeting the 1-hour RPO.
- ✗
Adjust the RTO to 8 hours to allow for more comprehensive backups.
Why it's wrong here
Changing the RTO does not resolve the RPO issue. The problem is data loss exceeding the allowed RPO, not the speed of recovery.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
