R4 receives BGP prefixes for AS 50 from both R2 and R3. You want to ensure that R4 chooses
R3 as the preferred path to reach 50.50.50/24.
Referring to the information shown in the exhibit, where would you apply a policy containing the
parameter local-preference 110 to accomplish this task?
A.
on R3, as import from R1
B.
on R3, as export towards R4
C.
on R2, as import from R1
D.
on R2, as export towards R4
higher local preference of 110 should be places on R3 as an export towards R4?

Absolutely right. B is the correct answer. Higher LP is preferred and can be used as export only.
