Referring to the ABR configuration shown in the exhibit, which two statements are correct? (Choose two.)

A. The ABR advertises a default route to the NSSA with a metric of 10.

B. To reach the ABR, routers within the NSSA add 10 to their calculated path cost.

C. The ABR advertises NSSA routes to the backbone area with a metric of 10.

D. To reach the ABR, routers within the NSSA use the metric 10 as their path cost.

Explanation:
You must explicitly configure the ABR to generate a default route when attached to a stub or not-so-stubby-area (NSSA). To inject a default route with a specified
metric value into the area, you must configure the default-metric option and specify a metric value.
