Suggested Answer: F 🗳️
Clienlink is not enabled and should be in a mixed client environment. Many networks still support a mix of 802.11a/g and 802.11n clients. Because 802.11a/g clients (legacy clients) operate at lower data rates, the older clients can reduce the capacity of the entire network. Cisco's ClientLink technology can help solve problems related to adoption of 802.11n in mixed-client networks by ensuring that 802.11a/g clients operate at the best possible rates, especially when they are near cell boundaries.

The answer is correct, but for the wrong reason. The problem is not because Clientlink is disabled, that will not prevent any users from connecting. Clientlink helps newer clients connect to better speeds when there are older clients on the same network. The reason the clients cannot connect is because the data rates 1Mb/s, 2Mb/s and 5Mb/s have all been disabled. Legacy 802.11 clients only support 1Mb/s or 2Mb/s, so there is no link type enabled they can use.
