NEW QUESTION # 222
Which type of wireless encryption is used for WPA2 in preshared key mode?
- A. RC4
- B. AES-256
- C. TKIP with RC4
- D. AES-128
Answer: B
Explanation:
Explanation
We can see in this picture we have to type 64 hexadecimal characters (256 bit) for the WPA2 passphrase so we can deduce the encryption is AES-256, not AES-128.

NEW QUESTION # 227
What is difference between RADIUS and TACACS+?
- A. RADIUS is most appropriate for dial authentication, but TACACS+ can be used for multiple types of authentication.
- B. TACACS+ separates authentication and authorization, and RADIUS merges them.
- C. TACACS+ encrypts only password information, and RADIUS encrypts the entire payload.
- D. RADIUS logs all commands that are entered by the administrator, but TACACS+ logs only start, stop, and interim commands.
Answer: B
Explanation:
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting.
