CompTIA SK0-005 Practice Test 43
Question 420
A change board is planning a verified response to this server event: A colocation rack is left unlocked and vendor staff can touch network and backup equipment without approved escort or access records. For the Data center physical access enforcement issue, which response elements belong in the approved plan? Select TWO answers.
- Apply approved sanitization or cryptographic erase methods appropriate to media and classification, then retain evidence.
- A controlled simulated environmental warning reaches responders in time and temperature stays within equipment range.
- Enforce badges, role-based room or rack access, visitor logging and periodic access-review procedures.
- Review door events, camera footage, approved visitor roster, rack locks and access recertification.
- Assume a building lobby badge is sufficient authorization for every server rack.
Explanation
Correct Answer
C:Physical access can bypass many software controls; identity, escort and audit are needed at equipment boundaries. A successful outcome is: Every access to sensitive equipment has valid authorization and traceable access records.
D:These observations investigate the exact Data center physical access enforcement failure rather than unrelated components. The expected technical relationship is: Physical access can bypass many software controls; identity, escort and audit are needed at equipment boundaries.
Incorrect Answers
A:That option would apply approved sanitization or cryptographic erase methods appropriate to media and classification, then retain evidence, but it addresses a different concern. Physical access can bypass many software controls; identity, escort and audit are needed at equipment boundaries.
B:This statement concerns Environmental monitoring and suppression, a different Server+ technical control. It does not directly address the reported Data center physical access enforcement fault or prove its repair.
E:This is the unsafe shortcut in the Data center physical access enforcement scenario, not a justified remediation or diagnostic. Discriminate using: Review door events, camera footage, approved visitor roster, rack locks and access recertification.
Question 421
