Question 34

Refer to the exhibit. The Math and Science departments connect through the corporate IT router, but users in the Math department must not be able to reach the

Science department and vice versa.

Which configuration accomplishes this task?

    Correct Answer: B

    The correct configuration involves defining the VRF (Virtual Routing and Forwarding) instance and then applying it to the relevant interfaces. This configuration ensures that routes within the Math department are isolated from the Science department. Option B correctly creates the VRF instance named 'Science', applies the VRF to the interfaces first, and then assigns IP addresses. This order is crucial because applying the VRF after the IP address would remove the IP address from the interface. Therefore, using 'vrf forwarding Science' followed by the IP address configuration ensures proper isolation and functionality.

bjromero28Option: B

Answer B is correct. Remember that you must add the vrf to the interface first and then the ip address. Adding the ip address before the vrf forwarding will remove the ip address from the interface.
