Question 1

A server administrator is investigating a server issue involving rack weight, rail compatibility and airflow: A branch office receives a dense 2U server whose rails fit the rack but the rear clearance obstructs hot-aisle exhaust and the shelf is above the rack load rating. The change must address the documented fault without creating unrelated risk. Which corrective action is most appropriate? Select ONE best answer.

  1. Install by physical fit alone and rely on higher fan speed to compensate for blocked exhaust.
  2. Place BMC access on an isolated management network, change default credentials, restrict administrator access and maintain supported firmware.
  3. Match the NIC, switch port, transceiver, cable medium and speed/duplex capability to the supported link standard.
  4. 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.

Explanation

Correct Answer

D:

Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.

Incorrect Answers

A:

This is the unsafe shortcut in the Rack weight, rail compatibility and airflow scenario, not a justified remediation or diagnostic. Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.

B:

This statement concerns Out-of-band management network, a different Server+ technical control. It does not directly address the reported Rack weight, rail compatibility and airflow fault or prove its repair. For this incident, the relevant principle is: Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation. A targeted investigation checks: Review chassis and rack load documents, weight distribution, rail part numbers, inlet temperature and actual front/rear clearances. The desired recovery condition is: The chassis is secured on compatible rails below rack capacity and sustained inlet and exhaust temperatures meet vendor limits.

C:

That option would match the NIC, switch port, transceiver, cable medium and speed/duplex capability to the supported link standard, but it addresses a different concern. Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.

Question 2

While reviewing the CompTIA Server+ administration incident, a technician learns: A branch office receives a dense 2U server whose rails fit the rack but the rear clearance obstructs hot-aisle exhaust and the shelf is above the rack load rating. Which principle most directly explains how to address the described issue safely? Select ONE best answer.

  1. Two PSUs are not a redundant power design when both depend on one upstream power device or circuit.
  2. Memory configuration depends on CPU/socket population and validated channel topology, not only DIMM physical fit or total gigabytes.
  3. Rack placement must satisfy structural loading, chassis mounting specifications and designed airflow; a physically fitting rail is not proof of safe installation.
  4. RAID 0 offers no disk fault tolerance; parity and mirrors have different write and rebuild characteristics, and none replaces backup.
