Which two of the following authentication methods used for WiFi security require the use of certificates? (Choose two.)
A . PEAP
B . EAP-FAST
C . WPA2
D . WPA1
E . EAP-TLS
F . EAP-MD5
Answer: AE
Explanation:
When you use EAP with a strong EAP type, such as TLS with smart cards or TLS with certificates, both the client and the server use certificates to verify their identities to each other. Certificates must meet specific requirements both on the server and on the client for successful authentication.
