CWNA: Certified Wireless Network Administrator v108 — Question 33

You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?

Answer options

• A. 800 ns
• B. 400 ns
• C. 104 ms
• D. 10 ms

Correct answer: B

Explanation

The short guard interval reduces the duration to 400 ns, which is beneficial for improving throughput in wireless communication. The other options, 800 ns, 104 ms, and 10 ms, represent longer intervals that do not apply when configuring for a short guard interval.
