A network engineer is implementing security on all company routers. Which two commands must be issued to force authentication via the password 1C34dE for all OSPF-enabled interfaces in the backbone area of the company network? (Choose two.)
- ip ospf message-digest-key 1 md5 1C34dE
- area 1 authentication message-digest
- username OSPF password 1C34dE
- enable password 1C34dE
- area 0 authentication message-digest
Explanation: The two commands that are necessary to configure authentication via the password 1C34dE for all OSPF-enabled interfaces in the backbone area (Area 0) of the company network would be ip ospf message-digest-key 1 md5 1C34dE and area 0 authentication message-digest. The option area 1 authentication message-digest is incorrect because it refers to Area 1, not Area 0. The option enable password 1C34dE is incorrect because it would set the privileged EXEC mode password instead of the OSPF authentication password. The option username OSPF password 1C34dE is required to create a username database in a router, which is not required with OSPF authentication.
