Question 30

A change board is planning a verified response to this server event: An application host gains a second CPU but its memory remains populated only on the first processor's channels, causing poor NUMA locality. For the CPU memory compatibility and population issue, which response elements belong in the approved plan? Select TWO answers.

  1. Validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance.
  2. Install any same-shape DIMMs in convenient slots and ignore processor-attached channel guidance.
  3. The chassis is secured on compatible rails below rack capacity and sustained inlet and exhaust temperatures meet vendor limits.
  4. Follow the motherboard and processor-qualified DIMM population map and validate supported capacity, speed, ranks and NUMA channel balance.
  5. Inspect qualified hardware lists, slot/channel maps, POST logs, detected speeds and NUMA memory distribution.

Explanation

Correct Answer

D:

Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes. Before rollout, confirm the problem with: Inspect qualified hardware lists, slot/channel maps, POST logs, detected speeds and NUMA memory distribution.

E:

These observations investigate the exact CPU memory compatibility and population failure rather than unrelated components. The expected technical relationship is: Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes.

Incorrect Answers

A:

That option would validate the hardware compatibility matrix, test firmware and drivers in a pilot, arrange rollback and stagger production maintenance, but it addresses a different concern. Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes.

B:

Discriminate using: Inspect qualified hardware lists, slot/channel maps, POST logs, detected speeds and NUMA memory distribution.

C:

This statement concerns Rack weight, rail compatibility and airflow, a different Server+ technical control. It does not directly address the reported CPU memory compatibility and population fault or prove its repair. For this incident, the relevant principle is: Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes.

Question 31

A server administrator is investigating a server issue involving out-of-band management network: A management controller shares its default factory password and reachable public management VLAN with ordinary user computers. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Follow the motherboard and processor-qualified DIMM population map and validate supported capacity, speed, ranks and NUMA channel balance.
  2. Connect redundant PSUs to independently protected PDU and UPS paths where available; size each path to carry the required load.
  3. Expose the factory-configured BMC to general users because the operating system firewall is enabled.
  4. Place BMC access on an isolated management network, change default credentials, restrict administrator access and maintain supported firmware.

Explanation

Correct Answer

D:

A successful outcome is: Only authorized administrators can reach and authenticate to the updated BMC over the isolated path. For this case, A management controller shares its default factory password and reachable public management VLAN with ordinary user computers.

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

B:

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 Dual power supply fault domains, a different Server+ technical control.

C:

This is the unsafe shortcut in the Out-of-band management network scenario, not a justified remediation or diagnostic. Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections.

Question 32

While reviewing the CompTIA Server+ administration incident, a technician learns: A management controller shares its default factory password and reachable public management VLAN with ordinary user computers. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Out-of-band controllers are privileged hardware management interfaces and need independent network and identity protections.
  2. Physical Ethernet links require interoperable media and interfaces; configuring an IP address cannot fix incompatible layer-one optics.
  3. Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.
  4. Preventive maintenance reduces recoverable downtime by detecting degrading components and planning compatible replacements.

Question 33

Before a server change is approved, the on-call engineer receives this incident report: A management controller shares its default factory password and reachable public management VLAN with ordinary user computers. Which evidence would most directly establish the stated root-cause hypothesis? Select ONE best answer.

  1. Inspect qualified hardware lists, slot/channel maps, POST logs, detected speeds and NUMA memory distribution.
  2. Inventory BMC firmware and accounts, scan exposed management interfaces and review management VLAN ACLs.
  3. Check NIC and switch support lists, module part IDs, cable labels, optical power, port errors and negotiated speed.
  4. Expose the factory-configured BMC to general users because the operating system firewall is enabled.

Question 34

After the team implements a targeted remediation for Out-of-band management network, the original incident was: A management controller shares its default factory password and reachable public management VLAN with ordinary user computers. 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 rebuild completes without new errors and the controller reports all expected redundancy restored.
  3. The chassis is secured on compatible rails below rack capacity and sustained inlet and exhaust temperatures meet vendor limits.
