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.

It is A and D
Specify the external metric type for the default LSA.
The configured metric determines the method used to compute the cost to a destination:
• The Type 1 external metric is equivalent to the link-state metric. The path cost uses the advertised external path cost and the path cost to the AS boundary router (the route is equal to the sum of all internal costs and the external cost).

it is A and B …
I lab it too
I lab it and it’s A & D!
A and B.
OSPF Metric Type 2 (default): path cost is constant
Type 1: path cost needs adding the base cost
AC
C – LSA7 into LSA5 translation will happen without a metric change . https://tools.ietf.org/html/rfc3101#section-1.3 and https://tools.ietf.org/html/rfc3101#section-3.2
Not B/Not D – to reach ABR , routers within NSSA area will use LSA1 of ABR to calculate the cost to
