Juniper JN0-643 Question Answer

R1 and R2 are ASBRs in the same area, each with an equal cost external path to the same external network prefix. R1 advertises an external route into OSPF with a Type 1 metric. R2 advertises an external route into OSPF with a Type 2 metric. Which route would be preferred?

A. R1's route is preferred because Type 1 metrics take into account the external cost only.
B. R1's route is preferred because Type 1 metrics take into account the internal and external cost.
C. R2's route is preferred because Type 2 metrics take into account the internal and external cost.
D. R2's route is preferred because Type 2 metrics take into account the external cost only.
