Final CCNA 4 ( G )

1.Refer to the exhibit. A network administrator is trying to configure a router to use SDM. After this configuration shown in the exhibit is applied, the SDM interface of the router is still not accessible. What is the cause of the problem?

*The username and password are not configured correctly.
The authentication method is not configured correctly.
The HTTP timeout policy is not configured correctly.
The vtys are not configured correctly.


2. Refer to the exhibit. Branch A has a non-Cisco router that is using IETF encapsulation and Branch B has a Cisco router.
