Refer to the exhibit. If configuring a static default route on the router with the ip route 0.0.0.0 0.0.0.0 10.13.0.1 120 command, how does the router respond?

A. It starts sending traffic without a specific matching entry in the routing table to GigabitEthernet0/1.
B. It immediately replaces the existing OSPF route in the routing table with the newly configured static route.
C. It starts load-balancing traffic between the two default routes.
D. It ignores the new static route until the existing OSPF default route is removed.

Correct Answer: D

Explanation:

Explanation:
Our new static default route has the Administrative Distance (AD) of 120, which is bigger than the AD of OSPF External route (O*E2) so it will not be pushed into the routing table until the current OSPF External route is removed.
For your information, if you don’t type the AD of 120 (using the command “ip route 0.0.0.0 0.0.0.0 10.13.0.1”) then the new static default route would replace the OSPF default route as the default AD of static route is 1.
You will see such line in the routing table:
S* 0.0.0.0/0 [1/0] via 10.13.0.1
