CWDP: Certified Wireless Design Professional v303 — Question 5

Switches and APs have already been chosen by your customer. All switches support 802.3bz MultiGig interfaces and APs are 4x4:4 802.11ac wave 2 capable of using dual-5GHz and have one MultiGig interface. Some cable drops for the APs will run for more than 180.5 feet (or 55 meters). To support MultiGig, what is the best choice of cabling?

Answer options

• A. Cat-5
• B. Cat-6
• C. Cat-5e
• D. Cat-6a

Correct answer: C

Explanation

The correct answer is Cat-5e, as it supports speeds up to 1 Gbps over distances greater than 100 meters, making it suitable for the requirements of the APs despite the longer cable runs. Cat-5 is not sufficient for MultiGig support, while Cat-6 and Cat-6a are over-spec for the given scenario and may not be necessary.
