JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 11

You are deploying PIM source-specific multicast (SSM) for a new multicast messaging service. You have configured the multicast source to use 235.44.123.100 as the multicast address. You are not able to join the PIM SSM multicast feed.
Which two solutions would resolve this problem? (Choose two.)

Answer options

• A. Reconfigure the multicast source to use an address in the range of 224.0.0.0 through 224.255.255.255.
• B. Reconfigure the multicast source to use an address in the range of 232.0.0.0 through 232.255.255.255.
• C. Add the multicast address to the [edit routing-options multicast ssm-map] stanza.
• D. Add the multicast address to the [edit routing-options multicast ssm-groups] stanza.

Correct answer: B, D

Explanation

Option B is correct because the address 235.44.123.100 is outside the valid SSM range, which is 232.0.0.0 to 232.255.255.255. Option D is also correct as this action allows the multicast address to be recognized as part of the SSM group. Options A and C are incorrect since they suggest using invalid address ranges or configurations that do not apply to SSM.
