Question
When an error version check, an engineer configures IGMP snooping on a device and the version of IGMP snooping is earlier than the IGMP versions on user hosts. In this case, which of the following situations will occur?
Options
- AUsers cannot receive multicast data because the device forwards received IGMP Report messages only to router ports and does not generate group member reports.
- BThe device generates forwarding entries only after receiving IGMP Query messages from a multicast router, and then periodically ages out existing entries.
- CThe device cannot identify the IGMP Report messages sent by users, and therefore fails to add users to multicast groups.
- DThe IGMP versions of the hosts are automatically upgraded, and users can receive multicast data properly.
