Wireless Questions 2

Question 1

Question 2

Explanation

Wi-Fi Protected Access version 3 (WPA3) is a new Wi-Fi Alliance’s (WFA) security standard for personal and enterprise networks. It aims to improve overall Wi-Fi security by using modern security algorithms and stronger cipher suites. WPA3 has two parts:

+ WPA3-Personal: Uses simultaneous authentication of equals (SAE) instead of pre-shared key (PSK), providing users with stronger security protections against attacks such as offline dictionary attacks, key recovery, and message forging.

+ WPA3-Enterprise: Offers stronger authentication and link-layer encryption methods, and an optional 192-bit security mode for sensitive security environments.

Question 3

Explanation

In Central Switched (Local) mode, an AP creates two CAPWAP tunnels to the Wireless Controller. One tunnel is used for forwarding data traffic and the other is used for forwarding the management traffic.

Question 4

Explanation

WPA/WPA2 preshared keys must contain 8 to 63 ASCII text characters or 64 hexadecimal characters.

Question 5

Explanation

In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels.

Question 6

Explanation

Band Select or Band Direction is a new feature that encourages dual band clients to connect to 5 G-Hz networks. Band select is disabled by default. The Band Select function provides a better wireless experience for users.
