Question 550

A change board is planning a verified response to this server event: A file backup restores directory names but misses ACLs and essential application metadata, violating recovery requirements. For the Application-consistent restore and integrity testing issue, which response elements belong in the approved plan? Select TWO answers.

  1. Test application-consistent restores including data, logs, permissions and integrity at defined intervals.
  2. An offline or isolated restore point survives a simulated primary-site or administrator compromise.
  3. Mark recovery complete solely when the backup agent reports a successful copy.
  4. Review backup job logs, quiesce/VSS status, restore checksums, ACLs and test-start results.
  5. Use narrowly scoped managed identities or service accounts and protect, rotate and revoke their secrets using approved storage.

Explanation

Correct Answer

A:

Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state. This is the appropriate targeted correction for Application-consistent restore and integrity testing.

D:

These observations investigate the exact Application-consistent restore and integrity testing failure rather than unrelated components. The expected technical relationship is: Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.

Incorrect Answers

B:

This statement concerns Immutable and offsite backup strategy, a different Server+ technical control. It does not directly address the reported Application-consistent restore and integrity testing fault or prove its repair.

C:

Incident: A file backup restores directory names but misses ACLs and essential application metadata, violating recovery requirements.

E:

That option would use narrowly scoped managed identities or service accounts and protect, rotate and revoke their secrets using approved storage, but it addresses a different concern. Successful data transfer alone does not establish recoverability; services need consistent artifacts and configuration state.

Question 551

A server administrator is investigating a server issue involving rpo and rto-driven disaster recovery: A payroll service requires recovery within two hours, but its documented restore procedure takes ten hours under rehearsal. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Revoke retired host credentials, certificates and network access, remove dependent records and close the asset lifecycle.
  2. Select recovery architecture to meet quantified RTO and RPO, then validate both during controlled recovery exercises.
  3. Include identity, DNS, network, certificates and data-dependency order in failover and failback runbooks; rehearse both directions.
  4. Treat a daily backup as automatically meeting a fifteen-minute RPO and two-hour RTO.

Explanation

Correct Answer

B:

RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices.

Incorrect Answers

A:

This statement concerns Decommissioning service identities and asset records, a different Server+ technical control. It does not directly address the reported RPO and RTO-driven disaster recovery fault or prove its repair. For this incident, the relevant principle is: RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices. A targeted investigation checks: Measure actual restore durations, last consistent recovery points, dependencies and recovery staff availability. The desired recovery condition is: A rehearsal restores end-to-end service within RTO and loses no more than allowed by RPO.

C:

That option would include identity, DNS, network, certificates and data-dependency order in failover and failback runbooks; rehearse both directions, but it addresses a different concern. RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices.

D:

This is the unsafe shortcut in the RPO and RTO-driven disaster recovery scenario, not a justified remediation or diagnostic. Incident: A payroll service requires recovery within two hours, but its documented restore procedure takes ten hours under rehearsal.

Question 552

While reviewing the CompTIA Server+ administration incident, a technician learns: A payroll service requires recovery within two hours, but its documented restore procedure takes ten hours under rehearsal. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Encryption in transit needs authenticated peers, valid trust chains and modern protocol settings, not merely an encrypted port.
  2. Trust in the operating system begins before it starts; firmware and measured boot support protection against boot-level changes.
  3. Patch management balances exposure reduction with service continuity using tested change windows and exception handling.
  4. RTO measures acceptable service restoration time; RPO measures acceptable data loss, and they drive different design choices.

Explanation
