JNCIS-DC: Juniper Networks Certified Specialist – Data Center — Question 17

You are deploying three WLAN 2.4 GHz networks in your US-based site. You must ensure that each network frequency is unique and does not overlap with the other frequency channels.
In this scenario, which three OFDM channels should be used? (Choose three.)

Answer options

• A. 11
• B. 1
• C. 3
• D. 6
• E. 13

Correct answer: A, B, D

Explanation

The correct channels are 1, 6, and 11 because they are the only non-overlapping channels in the 2.4 GHz band. Channels 3 and 13 overlap with other channels, which could cause interference in a WLAN deployment.
