C. Power and signaling efficiency is optimized for the UE.

D. The UE listens and responds to paging.

Which of the following statements regarding the 5G security components is FALSE?

A. The authentication credential repository and processing function (ARPF) selects the authentication method to use for the UE.

B. The authentication server function (AUSF) handles authentication requests for both 3GPP and non3GPP access.

C. The security anchor function (SEAF) makes the final decision on UE authentication.

D. The security identifier de-concealing function (SIDF) decrypts the UE's SUCI to obtain its corresponding SUPI.

Which of the following best describes a UE route selection policy (URSP)?

A. A URSP is a policy pre-configured in the UE. The UE uses this policy to select a non-3GPP access network and an N3IWF to use in the PLMN.

B. A URSP is a policy provisioned to AMF by PCF. The AMF uses this policy to select an SMF that can serve a given PDU session for the UE.

C. A URSP is a policy that can be pre-configured in the UE or provisioned to the UE by PCF. The UE uses this policy to determine how to handle a given application.

D. A URSP is a policy pre-configured on the SMF. The SMF uses this policy to select a UPF that can serve a given PDU session for the UE.
