Question: What is the primary purpose of a PDU Session Anchor in a 5G network?
Option 1: To provide a single point of access to the Data Network (DN) for all PDU Sessions.
Option 2: To enable the SMF to control the data path of a PDU Session and support selective traffic routing to the DN.
Option 3: To terminate multiple N6 interfaces and provide different accesses to the same DN, independent of the SSC mode of the PDU Session.
Option 4: To apply traffic routing based on DNAI(s) included in a PCC rule without using UL Classifier functionality or IPv6 multi-homing.
Explanation: A PDU Session Anchor is used to terminate multiple N6 interfaces and provide different accesses to the same DN, independent of the SSC mode of the PDU Session. This allows for selective traffic routing to the DN and supports deployments where some selected traffic is forwarded on an N6 interface to the DN that is "close" to the AN serving the UE.
