[&] What key is used for encrypting and decrypting unicast data in RSN?
- Master session key
- Pairwise master key
- Key encryption key
- Temporal key

[&] What is the primary role of the master session key in the RSN key derivation process?
- To encrypt all data transmitted in a Wi-Fi network
- To serve as the root for generating the pairwise master key
- To manage access control for connected devices
- To verify the identity of clients connecting to the network

[&] Why is a four-way handshake necessary in WPA security protocols?
- To verify that the client device is using the correct IP address
- To repeatedly check the client's Wi-Fi signal strength
- To distribute the master session key to all network clients
- To ensure unique encryption keys for different sessions

[&] Which protocol is used on the wired side for 802.1x authentication in WPA Enterprise?
- SMTP
- DNS
- SNMP
- RADIUS

[&] How is the pairwise master key derived in a WPA2 Personal network?
- By directly exchanging it between the supplicant and access point
- By running a pre-shared key through a specific formula
- By using unique digital certificates
- By splitting the master session key in half

[&] How is the group temporal key (GTK) in a WPA network delivered to clients securely?
- It is encrypted using the temporal key during a four-way handshake
- It is broadcasted over the network without encryption
- It is manually configured on each device
- It is encrypted using the key encryption key during a four-way handshake
