A network administrator is planning a VPN tunnel. Why would the engineer select main mode for IKE Phase 1?
- It requires less configuration.
- It is the industry standard.
- It is quicker.
- It is more secure.
Explanation: The two modes for IKE Phase 1 are main and aggressive. Main mode takes more time because the identity of the IKE peers are hidden from eavesdroppers. On Cisco devices, the default action for IKE authentication is to initiate main mode, but will respond to aggressive mode to a peer that has initiated aggressive mode.
