Question: What is the defined length of the Authentication Management Field (AMF) in 3GPP security specifications?
Option 1: 8 bits
Option 2: 16 bits
Option 3: 32 bits
Option 4: Variable, dependent on implementation
Explanation: According to the 3GPP security specifications, the Authentication Management Field (AMF) has a defined fixed length, ensuring consistency across implementations for interoperability and streamlined security protocols. The correct length is 16 bits, balancing necessary information with minimized overhead.
