CompTIA SK0-005 Practice Test 13
Question 120
A change board is planning a verified response to this server event: During a memory replacement, an engineer works on carpet without an ESD strap and treats the unplugged power supply as a reason to omit component handling safeguards. For the ESD and hot-swap replacement procedure issue, which response elements belong in the approved plan? Select TWO answers.
- Pilot and canary nodes pass hardware management and storage tests before controlled rollout completes.
- Assume every modular server part is hot-swappable and ESD precautions are optional.
- Check component hot-swap support, follow power isolation requirements and use approved ESD handling procedures.
- Use dedicated or appropriately isolated iSCSI paths with supported MPIO, correct initiator/target configuration and measured QoS.
- Consult the service manual, maintenance ticket, component status and grounding/ESD work area before removal.
Explanation
Correct Answer
C:Serviceable components differ in whether live replacement is safe, while electrostatic discharge can damage electronics even when mains power is removed. This is the appropriate targeted correction for ESD and hot-swap replacement procedure.
E:These observations investigate the exact ESD and hot-swap replacement procedure failure rather than unrelated components. The expected technical relationship is: Serviceable components differ in whether live replacement is safe, while electrostatic discharge can damage electronics even when mains power is removed.
Incorrect Answers
A:This statement concerns Firmware compatibility and staged maintenance, a different Server+ technical control. It does not directly address the reported ESD and hot-swap replacement procedure fault or prove its repair.
B:Incident: During a memory replacement, an engineer works on carpet without an ESD strap and treats the unplugged power supply as a reason to omit component handling safeguards.
D:That option would use dedicated or appropriately isolated iSCSI paths with supported MPIO, correct initiator/target configuration and measured QoS, but it addresses a different concern. Serviceable components differ in whether live replacement is safe, while electrostatic discharge can damage electronics even when mains power is removed. This statement concerns iSCSI network isolation and MPIO, a different Server+ technical control.
Question 121
A server administrator is investigating a server issue involving firmware compatibility and staged maintenance: A fleet update deploys a BMC firmware release incompatible with the installed BIOS, causing remote-console instability.

Question 122
While reviewing the CompTIA Server+ administration incident, a technician learns: A fleet update deploys a BMC firmware release incompatible with the installed BIOS, causing remote-console instability.
