Network+ Exam N10-007: CompTIA Network+ Practice Question

A network engineer is designing a new IDF in an old building.

The engineer determines the equipment will fit in a two-post rack, and there is power available for this equipment.

Which of the following would be the FIRST issue to remediate?

A.

Air flow and cooling

B.

UPS capability

C.

Circuit labeling

D.

Power redundancy.

A.

The correct answer is A. Air flow and cooling.

Explanation:

When designing a new IDF (Intermediate Distribution Frame) in an old building, the first issue that needs to be addressed is air flow and cooling. This is because the equipment generates heat, and if it is not properly cooled, it can overheat and cause damage or even a fire.

Air flow is important because it allows the equipment to breathe and circulate air. A lack of air flow can cause hot spots and lead to overheating. To ensure proper air flow, the engineer should make sure that there is enough space around the equipment and that the rack has proper ventilation.

Cooling is also important to prevent overheating. There are several ways to cool equipment, such as air conditioning, fans, or liquid cooling. The engineer should choose the appropriate cooling method based on the size and type of equipment and the environment in which it will be installed.

Once the air flow and cooling issues have been addressed, the engineer can move on to other concerns, such as UPS (Uninterruptible Power Supply) capability, circuit labeling, and power redundancy. UPS capability ensures that the equipment will continue to function in the event of a power outage or surge. Circuit labeling helps to identify which circuit is connected to each piece of equipment, making it easier to troubleshoot problems. Power redundancy ensures that there is a backup power source in case the primary power source fails.
