Alcatel-Lucent NRS II – Multicast Routing — Question 11

Which operation is performed by an interested PE upon receiving an MDT Join TLV?

Answer options

• A. The PE sends an (S, G) PIM Join with GRE encapsulation.
• B. The PE sends an (S, G) PIM Join with no encapsulation.
• C. The PE sends a (*, G) PIM Join with GRE encapsulation.
• D. The PE sends a (*, G) PIM Join with no encapsulation.

Correct answer: B

Explanation

The correct answer is B, as the PE sends an (S, G) PIM Join without any encapsulation in response to an MDT Join TLV. Options A and C incorrectly specify GRE encapsulation, which is not the case for this operation, while option D describes the wrong type of PIM Join by using a (*, G) instead of (S, G).
