CWNA: Certified Wireless Network Administrator v107 — Question 55

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

Correct answer: A

Explanation

The correct answer is A, as the short guard interval duration is defined as 400 nanoseconds in wireless communication standards. The other options do not represent the short guard interval settings and are considerably longer durations that are not applicable in this context.
