Configuring 5GHz Access Points

A

The correct answer is A. Client Band Select.

In this scenario, the engineer is observing high usage on the 2.4GHz channels and lower usage on the 5GHz channels. This can be due to a variety of factors, such as the higher number of devices that support the 2.4GHz band, or interference from other devices that operate on the same frequency.

To address this issue, the engineer must configure the wireless network to allow clients to preferentially use 5GHz access points. One way to achieve this is through the use of Client Band Select (CBS).

Client Band Select is a feature that allows the wireless network to actively encourage clients to connect to the 5GHz band by sending probe responses that contain information about available access points on both the 2.4GHz and 5GHz bands. The client devices can then use this information to select the best available access point based on signal strength and other factors.

By enabling Client Band Select, the wireless network can help distribute clients more evenly across both bands, reducing the congestion on the 2.4GHz band and improving overall network performance.

Re-Anchor Roamed Clients, OEAP Split Tunnel, and 11ac MU-MIMO are all valid features in their own right, but they are not directly related to the issue at hand, which is to allow clients to preferentially use 5GHz access points.
