When comparing PIM-DM and PIM-SM, which multicast components are only found with PIM-SM in multicast routing? (Choose two.)
A.
IGMP querier
B.
Rendezvous point
C.
Bootstrap router
D.
Shortest path tree
E.
Designated router
A rendezvous point (B) is used by SM only. Shortest path three (D) is optional for SM but available. Designated router (E) is available on SM only. So: BE
You are generally right. But the only exception is when you use IGMPv1 with Dense-Mode...in that case, the PIM DR will work as the IGMP query router because IGMPv1 doesn’t have a query router election.
B,E,

615, PIM-SM Designated Router.
P:617 PIM-SM Rendezvous Point.
I think its B and C.
In a multicast topology, BSR (Bootstrap) is a protocol that is used to automatically find the RP in a sparse mode network topology.
Page 627 Study Guide:
BSR is a RP high- availability mechanism that provides active/standby functionality and automatic downstream RP information propagation.

D. and E.

B and E.
B. Rendezvous point
C. Bootstrap router
E. Designated router
All three are uniquely for PIM SM.
Boostrap router to find Rendezvous point. Designated Router to act on the behalf of the multicast source.
Answer should be B & C.
B E
PIM-SM uses DR and RP
A designated router (DR) is required on both the source-side network and receiver-side network. A source-side DR acts on behalf of the multicast source to send register messages to the RP
BC SORRY on dense mode not exist rendevous point and designated routeR
BD , on dense mode not exist rendevous point and designated router
