CompTIA SK0-005 Practice Test 55
Question 540
A change board is planning a verified response to this server event: A branch office keeps three backup copies on one RAID array and calls this a full 3-2-1 strategy. For the Immutable and offsite backup strategy issue, which response elements belong in the approved plan? Select TWO answers.
- Inspect backup targets, credential separation, immutability, offsite status and restore-point freshness.
- Store all backups on the production server with the same administrator credentials.
- A recovered application opens consistent data and passes functional and permission tests at the target restore point.
- Implement least-privilege host or microsegmentation policies allowing documented source, destination and service combinations.
- Keep independent, access-isolated and preferably immutable/offsite backup copies with monitored schedules and retention.
Explanation
Correct Answer
A:These observations investigate the exact Immutable and offsite backup strategy failure rather than unrelated components. Incident: A branch office keeps three backup copies on one RAID array and calls this a full 3-2-1 strategy.
E:Backup resilience requires separation of failure and credential domains; multiple files on one failure domain are not independent copies.
Incorrect Answers
B:Discriminate using: Inspect backup targets, credential separation, immutability, offsite status and restore-point freshness.
C:For this incident, the relevant principle is: Backup resilience requires separation of failure and credential domains; multiple files on one failure domain are not independent copies. This statement concerns Application-consistent restore and integrity testing, a different Server+ technical control.
D:For this incident, the relevant principle is: Backup resilience requires separation of failure and credential domains; multiple files on one failure domain are not independent copies. It does not directly address the reported Immutable and offsite backup strategy fault or prove its repair.
Question 541
A server administrator is investigating a server issue involving application-consistent restore and integrity testing: A backup job reports green, but restoring a database produces transaction log mismatches and fails to start. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Mark recovery complete solely when the backup agent reports a successful copy.
- Select recovery architecture to meet quantified RTO and RPO, then validate both during controlled recovery exercises.
- Test application-consistent restores including data, logs, permissions and integrity at defined intervals.
- Keep independent, access-isolated and preferably immutable/offsite backup copies with monitored schedules and retention.
Explanation
Correct Answer
C:Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.
Incorrect Answers
A:This is the unsafe shortcut in the Application-consistent restore and integrity testing scenario, not a justified remediation or diagnostic. Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.
B:That option would select recovery architecture to meet quantified RTO and RPO, then validate both during controlled recovery exercises, but it addresses a different concern. Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.
D:That option would keep independent, access-isolated and preferably immutable/offsite backup copies with monitored schedules and retention, but it addresses a different concern. Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.
Question 542
While reviewing the CompTIA Server+ administration incident, a technician learns: A backup job reports green, but restoring a database produces transaction log mismatches and fails to start. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.
- A trusted internal network is not equivalent to all traffic being authorized; east-west access needs explicit boundaries.
- Risk-based remediation combines technical severity and local exposure; score alone does not establish operational priority.
- Physical environmental hazards can cause correlated service failures and must be detected before hardware shutdown.
Explanation
Correct Answer
A:Applying it leads to this operational action: Test application-consistent restores including data, logs, permissions and integrity at defined intervals.
Incorrect Answers

- A recovered application opens consistent data and passes functional and permission tests at the target restore point.
- A rehearsal restores end-to-end service within RTO and loses no more than allowed by RPO.
