Review the IKE debug output for IPsec shown in the exhibit below. Which statements is correct regarding this output?

IKE Phase 1 negotiation debug output would show exchanges related to security association establishment, key exchange, and authentication, which are distinct from DPD messages.

IKE Phase 2 negotiation debug output would display information about the IPsec Security Association (SA) establishment, including Quick Mode exchanges and traffic selector negotiation, not DPD messages.

Dead Peer Detection (DPD) messages, such as R-U-THERE and R-U-THERE-ACK, are part of the IKE protocol and appear in debug logs to verify the continued availability of the IPsec peer. These messages are crucial for quickly identifying and reacting to peer failures.

While DPD helps detect a 'dead gateway,' the specific term 'dead gateway detection packets' is not standard in IPsec debug output; the mechanism is called Dead Peer Detection.
