Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 51

An engineer must perform an assessment of a customer LAN for a future IEEE 802.11ac Wave 2 wireless deployment. All access switches are Fast Ethernet- capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)

Answer options

• A. Replace the existing switches with mGig switches.
• B. Ensure that cable distances between access switches and APs are not longer than 55 meters.
• C. Replace the existing switches with gigabit switches with 10 G uplinks.
• D. Ensure that cable distance between access switches and APs are not longer than 100 meters.
• E. Replace the existing wiring infrastructure with the CAT-7E wiring standard.

Correct answer: A, D

Explanation

Replacing the existing switches with mGig switches (Option A) allows for higher data rates that can support the capabilities of the Cisco 3800 Series access points. Ensuring that cable distances do not exceed 100 meters (Option D) is important to maintain signal integrity and performance, as distances longer than this can lead to potential issues. The other options either do not provide the necessary support or exceed the maximum distance requirement.
