Question 70
An office installs a new 6 GHz-capable AP, but an older 802.11ac laptop cannot detect the dedicated 6 GHz-only SSID. Which immediate engineering change most directly addresses this issue?
Explanation
Correct Answer
The underlying issue is that a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN. This intervention addresses that cause directly. A useful result to confirm is: the legacy laptop associates to its supported band while capable devices use 6 GHz.
Incorrect Answers
This is suited to a different condition, such as when a retail site uses multiple AP models but a uniform antenna-gain configuration that overstretches permitted EIRP in some areas. The reported fault instead arises because a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN.
This is suited to a different condition, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. The reported fault instead arises because a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN.
This is suited to a different condition, such as when an AP shows DFS radar events and channels change during business hours, interrupting some clients. The reported fault instead arises because a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN.
