Question
Which of the following descriptions of main mode and aggressive mode in IKE v1 are correct? (Multiple choice) (2) Identity protection: The main mode uses encryption to exchange identity information, while the brutal mode transmits identity information in clear text. (3) Negotiation ability: Due to the limitation of the number of exchanges in aggressive mode, the negotiation ability of aggressive mode is lower than that of main mode.
Options
- AMain mode does not support NAT traversal, and aggressive mode supports NAT traversal.
- BMain mode only supports IP address to identify identity, and aggressive mode supports IP
- CMain mode protects identity information, while brutal mode lacks protection of identity information.
- DMain mode uses 6 ISAKMP messages, and aggressive mode uses 3 ISAKMP messages.
