CompTIA A+ Core 1 (220-1101) — Question 24
Which of the following options provides correct information about 2.4GHz and 5GHz wireless frequencies? (Choose two.)
Answer options
- A. 2.4GHz has less interference. 5GHz transmits in lower speed.
- B. 2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections.
- C. 2.4GHz has a higher data rate. 5GHz has 23 channels.
- D. 2.4GHz has 11 channels. 5GHz has no data interference.
- E. 2.4GHz has a higher coverage area. 5GHz has higher bandwidth.
- F. 2.4GHz has a higher bandwidth. 5GHz has lower transmit power.
Correct answer: B, E
Explanation
Option B is correct because 2.4GHz frequencies are known for better penetration through obstacles, while 5GHz frequencies can provide faster data rates due to less congestion. Option E is also correct as 2.4GHz generally covers a wider area, whereas 5GHz offers higher bandwidth but over a shorter distance. The other options contain inaccuracies regarding the characteristics of these frequency bands.
