Which two statements about the PIM Assert message are true? (Choose two.)
A. It elects the device with the lowest administrative distance to the multicast source as the PIM Designated Router
B. It elects the device with the lowest IP address on the LAN segment as the PIM forwarder
C. It is triggered when multiple routers connected to a common LAN segment forward the same multicast packet
D. It elects the PIM router with the highest IP address on the LAN segment as the forwarder if remaining metrics are the same
E. It determines which router connected to a common LAN segment becomes the PIM Designated Router
F. It is triggered when multiple routers connected to a common LAN segment receive the same IGMP join request from a multicast receiver
PIM assert message is used to choose the router for forwarding multicasts onto the LAN if more than one router is connected to the same LAN. So it’s definitely not used for electing PIM Designated Router. Therefore C and D still remain only valid options.
It’s determined based on : 1. lowest AD of the routing protocol to learn the route of the source, 2. lowest advertised routing protocol metric, 3. highest IP address on that LAN
