Question 40

A change board is planning a verified response to this server event: A server shipment arrives with BMC firmware and IPMI enabled, but technicians plan to leave remote management on the production subnet during deployment. For the Out-of-band management network issue, which response elements belong in the approved plan? Select TWO answers.

  1. The chassis is secured on compatible rails below rack capacity and sustained inlet and exhaust temperatures meet vendor limits.
  2. Place BMC access on an isolated management network, change default credentials, restrict administrator access and maintain supported firmware.
  3. Select enterprise SSD endurance for the expected write volume and monitor NVMe health, utilization and replacement thresholds.
  4. Expose the factory-configured BMC to general users because the operating system firewall is enabled.
  5. Inventory BMC firmware and accounts, scan exposed management interfaces and review management VLAN ACLs.

Explanation

Correct Answer

B:

A successful outcome is: Only authorized administrators can reach and authenticate to the updated BMC over the isolated path. This is the appropriate targeted correction for Out-of-band management network.

E:

Confirm remediation through: Only authorized administrators can reach and authenticate to the updated BMC over the isolated path. The expected technical relationship is: Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections.

Incorrect Answers

A:

For this incident, the relevant principle is: Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections. This statement concerns Rack weight, rail compatibility and airflow, a different Server+ technical control.

C:

A targeted investigation checks: Inventory BMC firmware and accounts, scan exposed management interfaces and review management VLAN ACLs.

D:

Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections.

Question 41

A server administrator is investigating a server issue involving nic media and transceiver compatibility: A new 25-GbE adapter shows no link after an engineer inserts an unsupported optical module and uses the wrong fiber standard. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Match the NIC, switch port, transceiver, cable medium and speed/duplex capability to the supported link standard.
  2. Check the rack's weight rating, supported rails, front-to-back clearance and cold/hot aisle arrangement; mount heavier equipment low and preserve unobstructed cooling.
  3. Connect redundant PSUs to independently protected PDU and UPS paths where available; size each path to carry the required load.
  4. Force higher interface speed in software without checking optics, cable and switch capability.

Explanation

Correct Answer

A:

Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics. A successful outcome is: The port establishes the planned supported link speed with stable counters and no rising physical errors.

Incorrect Answers

B:

That option would check the rack's weight rating, supported rails, front-to-back clearance and cold/hot aisle arrangement; mount heavier equipment low and preserve unobstructed cooling, but it addresses a different concern. Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics.

C:

This statement concerns Dual power supply fault domains, a different Server+ technical control. It does not directly address the reported NIC media and transceiver compatibility fault or prove its repair. For this incident, the relevant principle is: Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics. A targeted investigation checks: Check NIC and switch support lists, module part IDs, cable labels, optical power, port errors and negotiated speed. The desired recovery condition is: The port establishes the planned supported link speed with stable counters and no rising physical errors.

D:

This is the unsafe shortcut in the NIC media and transceiver compatibility scenario, not a justified remediation or diagnostic. Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics.

Question 42

While reviewing the CompTIA Server+ administration incident, a technician learns: A new 25-GbE adapter shows no link after an engineer inserts an unsupported optical module and uses the wrong fiber standard. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics.
  2. Block-device capacity, partition or logical-volume capacity and filesystem capacity are separate layers that must be reconciled.
  3. Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections.
  4. Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes.

Explanation

Question 43

Before a server change is approved, the on-call engineer receives this incident report: A new 25-GbE adapter shows no link after an engineer inserts an unsupported optical module and uses the wrong fiber standard. Which evidence would most directly establish the stated root-cause hypothesis? Select ONE best answer.

  1. Inventory BMC firmware and accounts, scan exposed management interfaces and review management VLAN ACLs.
  2. Check NIC and switch support lists, module part IDs, cable labels, optical power, port errors and negotiated speed.
  3. Review chassis and rack load documents, weight distribution, rail part numbers, inlet temperature and actual front/rear clearances.
  4. Force higher interface speed in software without checking optics, cable and switch capability.

Question 44

After the team implements a targeted remediation for NIC media and transceiver compatibility, the original incident was: A new 25-GbE adapter shows no link after an engineer inserts an unsupported optical module and uses the wrong fiber standard. Which acceptance criterion would best demonstrate a durable and safe resolution? Select ONE best answer.

  1. A planned single-path outage leaves the server powered without overloading the remaining path.
  2. The port establishes the planned supported link speed with stable counters and no rising physical errors.
  3. Firmware reports the expected usable capacity and approved speed, with balanced populated channels and no training errors.
  4. Both planned storage paths are available and storage latency remains within limits during controlled network failover.
