Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 132

A network engineer is retrofitting an existing building wired with Category 5e with Cisco Aironet 3800 Series APs and mGig switches. Which cable length allows for 5G operation?

Answer options

• A. 70 m
• B. 120 m
• C. 130 m
• D. 150 m

Correct answer: A

Explanation

The correct answer is A, as 70 meters is the maximum length for 5G operation with Category 5e cabling and mGig switches. Options B, C, and D exceed this limit, which would not support the desired 5G functionality.
