Question 580

A change board is planning a verified response to this server event: A storage incident begins after patching, but engineers replace disks first without isolating whether firmware or filesystem changed. For the Structured troubleshooting hypothesis and controlled change issue, which response elements belong in the approved plan? Select TWO answers.

  1. Capture baseline symptoms, timeline, recent changes, comparison hosts and test results before modifying production.
  2. Make many unrelated configuration changes at once and select the apparent fix afterward.
  3. Record symptoms and recent changes, form a testable hypothesis, change one variable at a time and preserve rollback evidence.
  4. Service is restored within response targets, temporary risk is removed and a reproducible fix is documented.
  5. Trace and test PSU, cables, PDU, UPS and breaker paths under a safely controlled maintenance procedure.

Explanation

Correct Answer

A:

These observations investigate the exact Structured troubleshooting hypothesis and controlled change failure rather than unrelated components. The expected technical relationship is: A repeatable incident method isolates causes and prevents uncontrolled fixes from introducing new failures.

C:

Before rollout, confirm the problem with: Capture baseline symptoms, timeline, recent changes, comparison hosts and test results before modifying production. A repeatable incident method isolates causes and prevents uncontrolled fixes from introducing new failures.

Incorrect Answers

B:

Instead, the supported correction is: Record symptoms and recent changes, form a testable hypothesis, change one variable at a time and preserve rollback evidence. Discriminate using: Capture baseline symptoms, timeline, recent changes, comparison hosts and test results before modifying production.

D:

For this incident, the relevant principle is: A repeatable incident method isolates causes and prevents uncontrolled fixes from introducing new failures. This statement concerns Escalation, rollback and post-incident closure, a different Server+ technical control.

E:

For this incident, the relevant principle is: A repeatable incident method isolates causes and prevents uncontrolled fixes from introducing new failures. It does not directly address the reported Structured troubleshooting hypothesis and controlled change fault or prove its repair.

Question 581

A server administrator is investigating a server issue involving log correlation and evidence preservation: A server crashes intermittently but its rotating journal overwrites the only stack trace before investigators collect it. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Escalate using evidence and severity thresholds, apply a reversible supported workaround and remove temporary exceptions after root-cause review.
  2. Record symptoms and recent changes, form a testable hypothesis, change one variable at a time and preserve rollback evidence.
  3. Collect time-synchronized logs, hardware alerts and relevant volatile evidence according to incident procedures before destructive action.
  4. Delete event logs and reboot repeatedly before collecting any useful failure evidence.

Explanation

Correct Answer

C:

Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery. For this case, A server crashes intermittently but its rotating journal overwrites the only stack trace before investigators collect it.

Incorrect Answers

A:

This statement concerns Escalation, rollback and post-incident closure, a different Server+ technical control. It does not directly address the reported Log correlation and evidence preservation fault or prove its repair. For this incident, the relevant principle is: Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery. A targeted investigation checks: Correlate system, application, hypervisor and switch events using aligned timestamps and event identifiers. The desired recovery condition is: A traceable incident timeline identifies the failing component or service without destroying relevant records.

B:

That option would record symptoms and recent changes, form a testable hypothesis, change one variable at a time and preserve rollback evidence, but it addresses a different concern. Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery.

D:

This is the unsafe shortcut in the Log correlation and evidence preservation scenario, not a justified remediation or diagnostic. Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery.

Question 582

While reviewing the CompTIA Server+ administration incident, a technician learns: A server crashes intermittently but its rotating journal overwrites the only stack trace before investigators collect it. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Link-up alone does not establish link quality; CRC, FCS, drops and duplex mismatches reveal layer-one or layer-two faults.
  2. TLS trust failures are security-relevant authentication errors and require targeted trust repair, not blanket verification bypass.
  3. Correctable memory errors are early-warning evidence; a rising count can precede uncorrectable failures.
  4. Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery.

Explanation

Correct Answer

D:

The acceptance test is: A traceable incident timeline identifies the failing component or service without destroying relevant records.

Incorrect Answers

A targeted investigation checks: Correlate system, application, hypervisor and switch events using aligned timestamps and event identifiers. The desired recovery condition is: A traceable incident timeline identifies the failing component or service without destroying relevant records.

C:

This statement concerns Correctable ECC error escalation, a different Server+ technical control. It does not directly address the reported Log correlation and evidence preservation fault or prove its repair. For this incident, the relevant principle is: Evidence quality depends on provenance, timing and preservation, not only the volume of screenshots taken after recovery. A targeted investigation checks: Correlate system, application, hypervisor and switch events using aligned timestamps and event identifiers. The desired recovery condition is: A traceable incident timeline identifies the failing component or service without destroying relevant records.

Question 585

A change board is planning a verified response to this server event: A server crashes intermittently but its rotating journal overwrites the only stack trace before investigators collect it. For the Log correlation and evidence preservation issue, which response elements belong in the approved plan? Select ONE best answer.

  1. Inspect the certificate chain, names, validity and trusted roots, then renew or repair the appropriate certificates.
  2. Delete event logs and reboot repeatedly before collecting any useful failure evidence.
  3. Review EDR process trees, scheduled tasks, outbound connections, privileged logins and related host indicators.
  4. Collect time-synchronized logs, hardware alerts and relevant volatile evidence according to incident procedures before destructive action. Then validate the change by confirming: A traceable incident timeline identifies the failing component or service without destroying relevant records.

While reviewing the CompTIA Server+ administration incident, a technician learns: An administrator reboots a compromised machine and clears its logs before recording timestamps and network connections. Which principle most directly explains how to address the described issue safely? Select ONE best answer.
