Question 600

A change board is planning a verified response to this server event: A temporary firewall bypass restores a web service but remains undocumented and exposed after incident closure. For the Escalation, rollback and post-incident closure issue, which response elements belong in the approved plan? Select THREE answers.

  1. Contain unapproved egress, preserve flow and endpoint evidence and validate allowed destinations before reopening paths.
  2. Capture baseline symptoms, timeline, recent changes, comparison hosts and test results before modifying production.
  3. Leave emergency security bypasses permanent because the application now responds.
  4. Escalate using evidence and severity thresholds, apply a reversible supported workaround and remove temporary exceptions after root-cause review.
  5. Check outage severity, vendor case criteria, change ticket, workaround expiry and root cause evidence.
  6. Service is restored within response targets, temporary risk is removed and a reproducible fix is documented.

Explanation

Correct Answer

D:

Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor. A successful outcome is: Service is restored within response targets, temporary risk is removed and a reproducible fix is documented.

E:

These observations investigate the exact Escalation, rollback and post-incident closure failure rather than unrelated components. The expected technical relationship is: Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor.

F:

Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor. This evidence tests whether the original Escalation, rollback and post-incident closure weakness has been corrected under realistic conditions.

Incorrect Answers

A:

This statement concerns Unauthorized outbound traffic and exfiltration detection, a different Server+ technical control. It does not directly address the reported Escalation, rollback and post-incident closure fault or prove its repair. For this incident, the relevant principle is: Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor.

B:

This statement concerns Structured troubleshooting hypothesis and controlled change, a different Server+ technical control. It does not directly address the reported Escalation, rollback and post-incident closure fault or prove its repair. For this incident, the relevant principle is: Incident resolution includes timely escalation, safe rollback and documented follow-through, not just a green monitor. A targeted investigation checks: Check outage severity, vendor case criteria, change ticket, workaround expiry and root cause evidence. The desired recovery condition is: Service is restored within response targets, temporary risk is removed and a reproducible fix is documented.

C:

Incident: A temporary firewall bypass restores a web service but remains undocumented and exposed after incident closure.

Question 601

A server administrator is investigating a server issue involving thermal shutdown and heatsink diagnostics: A CPU host powers off under load after a heatsink replacement because thermal compound and fan attachment were mishandled. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Correlate ECC and memory training events with physical slots, then replace faulty qualified DIMMs using approved service steps.
  2. Trace and test PSU, cables, PDU, UPS and breaker paths under a safely controlled maintenance procedure.
  3. Inspect cooling path, heatsink mounting and sensor telemetry, then correct the thermal fault before increasing load.
  4. Disable thermal protections to keep an overheating server online.

Explanation

Correct Answer

C:

Thermal throttling and protective shutdown may result from heat transfer or airflow faults even without high average CPU use. For this case, A CPU host powers off under load after a heatsink replacement because thermal compound and fan attachment were mishandled.

Incorrect Answers

A:

This statement concerns Correctable ECC error escalation, a different Server+ technical control. It does not directly address the reported Thermal shutdown and heatsink diagnostics fault or prove its repair. For this incident, the relevant principle is: Thermal throttling and protective shutdown may result from heat transfer or airflow faults even without high average CPU use. A targeted investigation checks: Compare inlet/CPU temperatures, fan RPM, heatsink seating, thermal history and throttling event logs. The desired recovery condition is: Sustained stress tests run within component thermal limits without unexpected throttling or shutdown.

B:

That option would trace and test PSU, cables, PDU, UPS and breaker paths under a safely controlled maintenance procedure, but it addresses a different concern. Thermal throttling and protective shutdown may result from heat transfer or airflow faults even without high average CPU use.

D:

This is the unsafe shortcut in the Thermal shutdown and heatsink diagnostics scenario, not a justified remediation or diagnostic. Thermal throttling and protective shutdown may result from heat transfer or airflow faults even without high average CPU use.

Question 602

While reviewing the CompTIA Server+ administration incident, a technician learns: A CPU host powers off under load after a heatsink replacement because thermal compound and fan attachment were mishandled. 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. Thermal throttling and protective shutdown may result from heat transfer or airflow faults even without high average CPU use.
  3. Tagged VLAN traffic must be permitted end-to-end; routing changes do not repair a missing layer-two VLAN path.
  4. A repeatable incident method isolates causes and prevents uncontrolled fixes from introducing new failures.
