4A0-108 practice questions, page 8 of 10, with answer review and explanations.
Question 36
Refer to the following exhibit. Assuming all links have an equal metric in the IGP, where will the Shared Path Tree be built when Receiver 3 joins the multicast group?
Router G-E-C
Router G-E-C-A
Router G-E-D-B-A
There is insufficient information to answer
Question 37
Refer to the following exhibit. Assuming all links have an equal metric in the IGP, where will Source Path Tree have been created if Receiver 2 and Receiver 3 have joined the multicast group and the source is sending and the switchover has occurred? (Choose two)
Router F-D-B-A
Router G-E-C-A
Router C-E-D-B-A
Router G-E-C
Router F-D-E-C
Question 38
What is the function of the MDT?
It is how PIM neighbors become aware of each other
It is how receivers signal the source
It is the path to the RP
It is the multicast data forwarding path
It is the path to the DR
Question 39
What impact will an asymmetric IGP routing topology have on the PIM RPF check?
The PIM RPF check may fail since traffic from the source may arrive on one interface while the IP route to the source may point to another interface on the PIM router
PIM does not work in an asymmetric topology and therefore the RPF check will not be done
There will be no impact since the shared and source path trees are built from the receiver to the source
There is not enough information provided to answer the question
