A user requests one primary VLAN, two community VLANs, and two isolated VLANs for multicast capable servers that must transmit multicast traffic and receive multicast traffic through the use of IGMPv2
On which VLAN must the IGMP querier be configured?

A. B. C. D.C.
In this scenario, the user requires one primary VLAN, two community VLANs, and two isolated VLANs for multicast capable servers that must transmit multicast traffic and receive multicast traffic through the use of IGMPv2.
IGMPv2 (Internet Group Management Protocol version 2) is a multicast protocol used to manage membership of hosts in a multicast group. IGMP querier is a router or switch that sends IGMP queries to discover which multicast groups have active members on each network segment.
The IGMP querier should be configured on the VLAN that has hosts that need to receive multicast traffic. When IGMP queries are sent out on a VLAN, they are used to learn which hosts on that VLAN want to receive multicast traffic.
In this case, since the user requires multicast capable servers that must transmit and receive multicast traffic, it is necessary to configure IGMP querier on the VLANs that have hosts that need to receive multicast traffic.
Option A: Only the primary VLAN is incorrect because the user requires two community VLANs and two isolated VLANs for multicast capable servers.
Option B: Layer 2 multicast is not supported when using private VLANs is incorrect because the user did not mention the use of private VLANs.
Option C: The isolated VLAN and both community VLANs are correct VLANs for configuring IGMP querier because these VLANs have hosts that need to receive multicast traffic.
Option D: Primary and secondary VLANs is not a valid option since the user did not mention the use of secondary VLANs.
Therefore, the correct answer is option C: isolated VLAN and both community VLANs.
