AThere is a risk of electrostatic discharge.

BIn a data centre environment relative humidity is not important, only temperature matters.

CThere is a risk of not properly functioning of the smoke detectors.

DThere is a risk of corrosion.

Show Suggested Answer

Suggested Answer: D

High relative humidity in a data center can lead to corrosion of metal parts and electronic contacts, potentially causing failures. Electrostatic discharge is a risk with low humidity, not high.

I definitely remember something about electrostatic discharge being a risk, but I can't remember if that was related to high humidity or low humidity.

I feel like we discussed how humidity is important in data centres, but I can’t recall if it was just about temperature or not.

I’m not sure, but I think I read somewhere that humidity affects smoke detectors too. Could it be C?

Okay, I'm leaning towards C on this one. If the humidity is too high, it could interfere with the proper functioning of the smoke detectors, which would be a major issue in a data centre. I'll double-check the other options, but that's my initial thought.

I think the answer is D. High humidity can lead to corrosion of the metal components in the data centre, which could cause all sorts of problems. I remember learning about that in one of my IT courses.

B seems like the wrong answer to me. Even if temperature is the primary concern, relative humidity can't be ignored in a data centre environment. I'm pretty confident that A or D is the correct response here.

Hmm, I'm not sure about this one. I know that temperature is really important in a data centre, but I thought humidity was also a factor. I'll have to think this through a bit more.
