Alcatel-Lucent NRS II – Multicast Routing — Question 2

Which of the following events could trigger a PIM router sending an (S,G) Join message? (Choose three)

Answer options

• A. Receiver performing IGMP version 3 (S, G) report
• B. Receiver performing enhanced IGMP version 2 signaling
• C. Router performing PIM Source Path Tree signaling
• D. Router performing translation to convert a standard IGMP (*, G) Join into a PIM (S, G) Join
• E. RP performing translation to convert a PIM (*, G) Join into a PIM (S, G) Join

Correct answer: B

Explanation

The correct answer is B, as enhanced IGMP version 2 signaling can indeed prompt a PIM router to send an (S,G) Join message. The other options either involve actions that do not directly initiate an (S,G) Join or pertain to different protocols or processes that do not lead to the specified action.
