A) WPA-PSK
B) EAP-TLS
C) AES-CCMP
D) WEP-TKIP

Accepted Answer

EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) is a certificate-based authentication method that can prevent unauthorized users from accessing the network by requiring a valid certificate for authentication.

Question 12

A university has a lecture hall containing 100 students. Currently, the lecture hall has two 802.11ac wireless access points, which can accommodate up to 50 devices each. Several students report they are unable to connect devices to the wireless network. Which of the following is MOST likely the issue?
