An administrator is implementing a multicast solution in a multi-VLAN network. Which statement is true about the configuration of the switches in the network?

IGMP must be enabled on all routed interfaces where multicast traffic will traverse. This ensures that the routers can participate in IGMP signaling and properly handle the multicast traffic, allowing them to manage the membership information of multicast groups and ensure efficient multicast data delivery across the network.
Looks like C is correct. Found a PDF the specifically says this. Google "AOS-CX switch igmp", first result (pdf), then go to "Multicast Deployment Summary". A - incorrect. This is configured globally on the switch, not per-interface. B - incorrect. This is a PIM function. Not IGMP. D - incorrect. IGMP is enabled on L3 interfaces towards the sources/receivers. Not ALL interfaces.
Thanks bro i have tomorrow my exam.
did you pass?
D is correct. IGMP is enabled only on clients and multicast servers VLAN. PIM is enabled on routed interfaces between clients and servers VLAN to route multicast flow
C - Book states "If you want the benefits of IGMP in VLAN 30, you must enable it on the routed interface for VLAN 30" and "You enable IGMP on a per VLAN basis."
the correct Answer is C
C is correct Graft and prune relate to PIM-DM not IGMP
None of these are correct. I'm going to assume they are talking about VLAN interfaces, and go with answer D if I get this question on the test. https://i.imgur.com/vW7V2UL.png
in the picture you shared is saying that "igmp enable snooping optional but recommended" but answer "D" is saying it must be enabled. so D is not correct
be carefull, "igmp snooping" is different from "igmp", on the picture they sayed "PIM-DM and IGMP enabled on correct interface"
the question is specifically asking for switch config, so I think D is correct. What is mentioned in B happens anyway (with version 3 IGMP) without any extra config being done. i.e. Without IGMP in place PIM will not work.
C page 531
when are you planning to do the exam? or have you already done it?
Look at module 9 page 17 and 18. I think D is correct.
D is correct. See "AOS-CX Multicast deployment and troubleshooting guide" page 8 Multicast Deployment Summary point 6: "Enable IGMP/MLD on L3 interfaces towards receiver subnets"
It's C. You answer says it. "L3 interfaces" Option D says nothing about routed interfaces.
C is correct
I think D is correct A - incorrect, switches will always forward traffic B - Graft and Prune are PIM functions C - IGMP is only required on the VLAN where the receivers and source are connected, PIM is required across L3 domains. IGMP manages flooding of multicast on a segment. D - Correct - VLAN interfaces where source and receivers are connected
C is correct
C: IGMP must be enabled on all routed interfaces. This allows the routers to participate in IGMP signaling and properly handle the multicast traffic.
C: IGMP has to be configured on routed interfaces
Page 567 Study Guide: A querier is required for proper IGMP operation. For this reason, you must enable IGMP on the L3 Interface. If the querier functionality is not configured or disabled, you must ensure that there is an IGMP querier in the same VLAN. [Aruba Networks]
A is false because IGMP snooping is enable on vlan and not on interface B is false because Graft & Prune are used by PIM D is false because they sayd only "interface" and not "routed interface", IGMP cannot be enable on switch interface, only on "routed interface" C seems to be correct
