Q39. Refer the exhibit. Two Autonomous Systems are enabled to support multicast. An engineer wants to set up configuration so that a multicast client at AS 100 can receive multicast traffic from the M-Server at AS 200. However, the RP announcements must be limited within each autonomous system site. Which Cisco IOS configuration achieves this goal?
A. On both ASBRs Eth0/0 and the no ip pim sparse-mode command.
B. On both ASBRs add the ip pim send-rp-discovery scope 1 command.
C. On both RPs add the ip pim send-rp-discovery scope 2 command.
D. On both ASBRs Eth0/0 add the ip pim bsr-border command.
E. On both ASBRs Eth0/0 add the ip pim dense-mode command.
F. On both RPs add the ip pim bsr-border command.

Q40. Refer to the exhibit.
R1 is using the RP that is learned via BSR R1 also has a static RP configuration in place.
In order to prefer the static RP over BSR, which configuration should be applied on R1?
A. ip pim bsr-candidate loopback 0 priority 200
B. ip pim rp-address 18.104.22.168 priority 200
C. ip pim bsr-candidate loopback 0 override
D. ip pim rp-address 22.214.171.124 override
