Refer to the exhibit.
Which two statements are true about the loopback address that is configured on RouterB? (Choose two.)
A . It ensures that data will be forwarded by Router
C . It provides stability for the OSPF process on Router
E . It specifies that the router ID for RouterB should be 10.0.0.1.
F . It decreases the metric for routes that are advertised from Router
H . It indicates that RouterB should be elected the DR for the LA
Answer: B, C
Explanation:
A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) – B is correct.
The router-ID is chosen in the order below:
The highest IP address assigned to a loopback (logical) interface.
If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen.
-The loopback interface will be chosen as the router ID of RouterB – C is correct.
