CompTIA N10-009 Exam - Topic 1 Question 33 Discussion

Actual exam question for CompTIA's N10-009 exam

Question #: 33
Topic #: 1

Which of the following physical installation factors is the most important when a network switch is installed in a sealed enclosure?

AFire suppression

BPower budget

CTemperature

DHumidity

Show Suggested Answer

Suggested Answer: C

Switches in sealed enclosures are at risk of overheating because airflow is restricted. The temperature factor is critical since heat buildup can damage components, shorten device lifespan, and cause outages. Proper cooling or ventilation must be ensured.

A . Fire suppression is important for data centers but not the primary concern in a sealed box.

B . Power budget applies to PoE allocations, not environmental safety.

D . Humidity matters, but overheating is far more immediate in sealed environments.

B) Power budget is key. You need to make sure the enclosure can handle the switch's power requirements, or it'll be a real shock when it shuts down.

D) Humidity is crucial. You don't want your switch to turn into a sauna and start growing mold, do you?

Fire suppression seems less relevant than temperature and humidity, but I guess it could be a factor if there's a risk of overheating.

I want to say power budget is important too, but I can't recall how it compares to the other factors in a sealed environment.

I remember a practice question where humidity was highlighted as a concern, but I feel like temperature might actually take precedence in this scenario.

I think temperature is crucial in a sealed enclosure since overheating can cause hardware failures, but I'm not entirely sure if it's the most important factor.

Tough one. I'd probably go with temperature, but I'm not 100% confident on that. Gotta think through the potential issues in a sealed environment.

Ooh, good question. I'd say the fire suppression is the most crucial - you don't want a switch fire to spread in a sealed box.

I'm leaning towards humidity as the most important factor. Moisture buildup in a sealed enclosure could really damage the switch's internal components.

I'm not sure, the power budget could also be really critical. If the enclosure doesn't have enough power capacity, the switch might not work properly.

Hmm, I think the temperature would be the most important factor here. The switch needs to be able to dissipate heat properly in a sealed enclosure.
