Designing Cisco Wireless Enterprise Networks (WIDESIGN, legacy) — Question 1

During an installation of a wireless network in a country that follows ETSI standards, the customer is requesting to manually set the channels on the 2.4GHz radios. Which channels are recommended for use in this deployment?

Answer options

• A. 52, 56, 60, 64
• B. 1, 6, 11, 14
• C. 36, 40, 44, 48
• D. 1, 5, 9, 13

Correct answer: C

Explanation

The correct answer is C, as channels 36, 40, 44, and 48 are compliant with ETSI standards for the 5GHz band, while the other options contain channels that are not permitted or not optimal for 2.4GHz deployment. Channels 1, 6, and 11 in option B are common for 2.4GHz but do not pertain to the ETSI requirement, and options A and D include channels that are not valid for this frequency range.
