[All 220-1101 Questions]

Which of the following options provides correct information about 2.4GHz and 5GHz wireless frequencies? (Select TWO)

A2.4GHz has less interference. 5GHz transmits inlower speed.

B2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections.

C2.4GHz has a higher data rate. 5GHz has 23 channels.

D2.4GHz has Il channels. 5GHz has no data interference.

E2.4GHz has a higher coverage area. 5GHz has higher bandwidth.

F2.4GHz has a higher bandwidth. 5GHz has lower transmit power.

Show Suggested Answer

Suggested Answer: A

When replacing a power supply in a computer, wearing an antistatic wrist strap is crucial to prevent static electricity from damaging the computer components. Static electricity can easily damage sensitive electronic components within the computer; therefore, using an antistatic wrist strap helps to ground the technician, mitigating the risk of electrostatic discharge. The other options provide general safety but do not address the primary concern of electrostatic discharge in this context.

Reference: CompTIA A+ Core 1 (220-1101) objectives covering best practices for hardware maintenance, including electrostatic discharge prevention.

Wait, there are different wireless frequencies? I thought it was just the one that goes 'beep boop beep' and makes my phone work. As long as I can still stream cat videos, I'm good. Anyway, I'm going with B and E because they sound the most legit.

Okay, let's see here. I think the correct answers are B and E. 2.4GHz penetrates better, and 5GHz has higher bandwidth. Simple as that! Now, if only I could find a way to boost my Wi-Fi signal using a microwave and a paper clip...

Ah, the age-old 2.4GHz vs. 5GHz debate! I'll go with B and E. Can't go wrong with faster data and higher bandwidth, am I right? Except for that one time I downloaded the entire Internet in 2 seconds... good times.

Hmm, I'm not sure about this one. Let me think... I guess C and F could be correct. 2.4GHz has a higher data rate, and 5GHz has higher bandwidth. Wait, is that right? I better double-check my notes.

But B and E make more sense because 2.4GHz penetrates solid objects better and has higher coverage area, while 5GHz has higher bandwidth.

I think B and E are the correct options. 2.4GHz does penetrate objects better, and 5GHz provides faster data connections. Definitely make sure I get those right on the exam!
