CompTIA SK0-005 Practice Test 57
Question 560
A change board is planning a verified response to this server event: A medical system has a fifteen-minute maximum data-loss objective yet replicates nightly with no log shipping. For the RPO and RTO-driven disaster recovery issue, which response elements belong in the approved plan? Select TWO answers.
- Users complete critical transactions in the alternate site, and a rehearsed failback restores a consistent primary.
- Select recovery architecture to meet quantified RTO and RPO, then validate both during controlled recovery exercises.
- Treat a daily backup as automatically meeting a fifteen-minute RPO and two-hour RTO.
- Measure actual restore durations, last consistent recovery points, dependencies and recovery staff availability.
- Prioritize verified vulnerabilities by exploitability, exposure and business impact; apply supported remediations with evidence.
Explanation
Correct Answer
B:RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices. This is the appropriate targeted correction for RPO and RTO-driven disaster recovery.
D:These observations investigate the exact RPO and RTO-driven disaster recovery failure rather than unrelated components. The expected technical relationship is: RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices.
Incorrect Answers
A:This statement concerns Site failover dependencies and failback, a different Server+ technical control. It does not directly address the reported RPO and RTO-driven disaster recovery fault or prove its repair.
C:Discriminate using: Measure actual restore durations, last consistent recovery points, dependencies and recovery staff availability.
E:This statement concerns Vulnerability scanning and prioritization, a different Server+ technical control. It does not directly address the reported RPO and RTO-driven disaster recovery fault or prove its repair.
Question 561
A server administrator is investigating a server issue involving site failover dependencies and failback: A disaster recovery site can start application VMs but cannot authenticate users because its DNS and identity services were never included. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.
- Include identity, DNS, network, certificates and data-dependency order in failover and failback runbooks; rehearse both directions.
- Enable supported Secure Boot and TPM-backed integrity or key protection with verified recovery procedures.
- Assume starting the application VM at a second site constitutes full disaster recovery.
- Select recovery architecture to meet quantified RTO and RPO, then validate both during controlled recovery exercises.
Explanation
Correct Answer
A:Recovery is a dependency graph, not a collection of powered-on VMs; failback can require careful data reconciliation.
Incorrect Answers
B:That option would enable supported Secure Boot and TPM-backed integrity or key protection with verified recovery procedures, but it addresses a different concern. Recovery is a dependency graph, not a collection of powered-on VMs; failback can require careful data reconciliation.
C:This is the unsafe shortcut in the Site failover dependencies and failback scenario, not a justified remediation or diagnostic. Recovery is a dependency graph, not a collection of powered-on VMs; failback can require careful data reconciliation.
D: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. Recovery is a dependency graph, not a collection of powered-on VMs; failback can require careful data reconciliation.
Question 562
While reviewing the CompTIA Server+ administration incident, a technician learns: A disaster recovery site can start application VMs but cannot authenticate users because its DNS and identity services were never included. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
- Physical access can bypass many software controls; identity, escort and audit are needed at equipment boundaries.
- Decommissioning includes logical trust and configuration removal, not just powering off and discarding hardware.
- Recovery is a dependency graph, not a collection of powered-on VMs; failback can require careful data reconciliation.
- Risk-based remediation combines technical severity and local exposure; score alone does not establish operational priority.
Explanation
Correct Answer

- Password knowledge alone is weak proof of administrator identity; emergency access needs protected exceptions and traceability.
