5GHz Access Points Configuration

A.

To allow clients to preferentially use 5GHz access points, the appropriate configuration would be to enable "Client Band Select". This feature helps to ensure that clients capable of connecting to both 2.4GHz and 5GHz networks will connect to the 5GHz network whenever possible.

Here's how it works: When a client device sends an association request to an access point, the access point includes information about both the 2.4GHz and 5GHz networks. The client then selects which network to join based on its capabilities and signal strength. With Client Band Select enabled, the access point can influence the client's decision by either encouraging or discouraging the use of one network over the other.

In this case, enabling Client Band Select would encourage clients to use the 5GHz network more frequently, which would help to balance the load across the different channels and potentially improve overall network performance.

The other options listed are not relevant to this scenario:

• "Re-Anchor Roamed Clients" is a feature that helps to optimize roaming behavior for clients that move between access points, but it would not address the issue of high usage on 2.4GHz channels.
• "OEAP Split Tunnel" is a feature that allows for a remote office to have its own local Internet breakout rather than sending all traffic through a central location, but it is not relevant to this scenario.
• "11ac MU-MIMO" is a feature of the 802.11ac wireless standard that allows multiple clients to simultaneously receive data from an access point, but it would not address the issue of high usage on 2.4GHz channels or help to encourage clients to use the 5GHz network.
