Show answer
Answer: C
Explanation
per ChatGPT (I know, use at your own risk...): The second set of traffic selectors negotiated between two peers using IKEv2 will be included in the CREATE_CHILD_SA exchange. This exchange is used to establish a new child SA within an existing IKE SA. The CREATE_CHILD_SA exchange is initiated by the initiator, and the responder replies with a CREATE_CHILD_SA response. The CREATE_CHILD_SA exchange contains the following payloads: Initiator's nonce SA proposal Traffic selector proposal Key exchange data IDi (Initiator's Identification) IDr (Responder's Identification) Authentication data The SA proposal and traffic selector proposal payloads will contain the details of the second set of traffic selectors negotiated between the peers. These proposals will include the specific traffic selectors for the new child SA, such as IP addresses and port numbers.
