Question 670
An office installs a new 6 GHz-capable AP, but an older 802.11ac laptop cannot detect the dedicated 6 GHz-only SSID. Which ongoing operational safeguard best reduces the chance of recurrence?
Explanation
Correct Answer
This is a continuing control for the failure mode in which a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN. It complements the immediate fix instead of relying on a one-off correction.
Incorrect Answers
That control is useful for a different failure, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when a campus is migrating staff to WPA3-Enterprise but several devices only support WPA2-Enterprise. It would leave the present failure mode insufficiently addressed.
That control is useful for a different failure, such as when a retail site uses multiple AP models but a uniform antenna-gain configuration that overstretches permitted EIRP in some areas. It would leave the present failure mode insufficiently addressed.
