Question: What is the main purpose of the primary authentication and key agreement procedure in the 5G System (5GS)?
Option 1: To enable mutual authentication between the UE and the network, and to provide keying material for subsequent security procedures.
Option 2: To establish a secure connection between the UE and the AMF for data transfer.
Option 3: To authenticate the UE's identity to the network using only the EAP method.
Option 4: To provide encryption keys for the UE and the network to use in subsequent communication.
Explanation: The primary authentication and key agreement procedure is designed to enable mutual authentication between the User Equipment (UE) and the network, as well as to provide keying material that can be used in subsequent security procedures. This ensures a secure connection between the UE and the network, allowing for trusted communication and data transfer.
