Referring to the exhibit, which statement is true regarding the OSPF network LSA?
A. The ID field value shows the router ID of the advertising router.
B. The ID field is the local interface IP address from which the LSA will be advertised.
C. The options field indicates this is a Type 2 LSA.
D. The output shows that 192.168.20.1 is the designated router.
Answer: D
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.
Answer: D
