[&] What types of frames are defined by the 802.11 Wi-Fi standard?
- Secure, Non-secure, and Semi-secure frames
- Broadcast, Multicast, and Unicast frames
- Encrypted, Unencrypted, and Authenticated frames
- Data, Control, and Management frames -- Correct

[&] How does PMF protect against replay attacks?
- By using encryption keys that change with each frame
- By storing logs of all transmitted management frames
- By adding a counter in the initialization vector -- Correct
- By securing frames with advanced encryption protocols

[&] Why can't management frames in Wi-Fi networks be encrypted (Select Two Answers)?
- Encryption would be too processor-intensive for management frames -- Correct
- It's redundant since data frames are already encrypted
- They must be understood by all clients prior to association -- Correct
- Encryption would cause compatibility issues with legacy devices

[&] What does WPA3 require concerning protected management frames?
- They must be required for operation -- Correct
- They are optional and can be disabled
- They must be encrypted for all clients
- They are only mandatory for WPA3-SAE WLANs

[&] What role does the Integrity Group Temporal Key (IGTK) play in PMF?
- It authenticates individual clients in the network
- It creates message integrity codes for broadcast/multicast frames -- Correct
- It isolates base stations to prevent signal leakage
- It encrypts management frames before transmission

[&] What is the primary purpose of management frames in Wi-Fi networks?
- To initiate and control cli connections to access points
- To ensure data encryption during transmission
- To manage authentication and association processes -- Correct
- To provide network security and device integrity
