Answers
D.
Wireless client isolation is enforced on the WLAN settings.
Suggested answer: C

Explanation:

A captive portal is a web page that is displayed to newly connected users of a Wi-Fi network before they are granted broader access to network resources.Captive portals are commonly used to present a landing or log-in page which may require authentication, payment, acceptance of an end-user license agreement, acceptable use policy, survey completion, or other valid credentials that both the host and user agree to adhere by123

A possible cause of the issue is that the user has not completed the captive portal authentication process, which prevents the VPN from establishing a secure connection over the Wi-Fi network. The user may need to open a web browser and follow the instructions on the captive portal page to gain full access to the internet.
