CompTIA Exam FC0-U61 Topic 2 Question 55 Discussion

Actual exam question for CompTIA's FC0-U61 exam

Question #: 55
Topic #: 2

A technician needs to install and configure a wireless SOHO network. Which of the following should the technician configure to reduce Wi-Fi interference from other household appliances?

A2.4GHz

B5GHz

C802.11b

D802.11g

Show Suggested Answer

Suggested Answer: B

The 5GHz frequency band is less prone to interference from other household appliances, such as microwaves, cordless phones, and Bluetooth devices, than the 2.4GHz band. The 5GHz band also offers more non-overlapping channels and higher data rates than the 2.4GHz band. However, the 5GHz band has a shorter range and lower penetration than the 2.4GHz band, so the technician should consider the size and layout of the SOHO network before choosing the frequency band. 802.11b and 802.11g are wireless standards that operate in the 2.4GHz band, while 802.11a, 802.11n, and 802.11ac can operate in both the 2.4GHz and 5GHz bands.Reference:

That's true, 2.4GHz has better range and can penetrate walls better.

I see your point, but 5GHz may not have as much range as 2.4GHz.

But wouldn't configuring 5GHz be better for reducing interference?

Actually, I would go with 2.4GHz as well. It's more commonly used in SOHO environments.

You know, I'm actually leaning towards 802.11g. It's a good compromise between speed and compatibility, and it might just give us a fighting chance against those interfering appliances.

Haha, yeah 802.11b, really? That's like using a rotary phone in the age of smartphones. I'd go with 5GHz too, it's the way to future-proof your network.

Definitely 5GHz. 2.4GHz is just way too crowded these days with all the wireless gadgets in our homes. I mean, who even uses 802.11b or 802.11g anymore? That's so last decade!

I agree, 5GHz is the way to go. That higher frequency is less prone to interference from things like microwaves, Bluetooth devices, and cordless phones. Plus, you get faster speeds with 802.11ac on the 5GHz band.

Hmm, this question seems pretty straightforward. I think the answer is B) 5GHz. Wouldn't that help reduce interference from other household appliances that typically operate on the 2.4GHz frequency band?

Ooh, I'm feeling lucky. Let's go with 802.11b, just to keep them on their toes. Who needs 5GHz when you can have the good old 802.11b?

2.4GHz is the way to go, my friends. That's where all the household appliances like microwaves and Bluetooth devices operate, so we need to steer clear of that frequency range.

Ah, the classic Wi-Fi interference question. I wonder if they'll throw in a red herring like 802.11b or 802.11g just to trip us up.
