Click the Exhibit button.
You are the administrator for the network shown in the exhibit. R1 receives the
1 96.15.4.0/24 route from routers R2, R3, and R4. Local preference values have not been modified in this network. You are asked to ensure that R1 prefers the path through AS
3 149 for traffic destined to 196.15.4.0/24.
Which two methods will accomplish this task? (Choose two.)

• A.Configure as-path-prepend on R2 and R4.
• B.Configure always-compare-med on R1.
• C.Configure local-as on R3.
• D.Configure a lower local preference on R3.

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