Actual exam question for Huawei's H12-821_V1.0 exam

Question #: 91
Topic #: 5

Based on IGMP snooping, IGMP snooping proxy enables a switch to act as a substitute for an upstream Layer 3 device to send IGMP Query messages to downstream hosts, and also to act as a substitute for downstream hosts to send IGMP Report/Leave messages to an upstream device. As such, this function conserves bandwidth between the upstream device and the local device.

Wait, can a switch really replace a Layer 3 device? That seems odd.

Okay, I think I've got a handle on this. The key is understanding that the IGMP snooping proxy acts as an intermediary, sending queries and reports on behalf of the upstream and downstream devices. This should conserve bandwidth, so I'll go with TRUE.
