- B. Policing discards packets that exceed the configured rate, with no other configurable actions.
- C. Policing is used for rewriting rules based on bandwidth usage.

You need to dynamically assign network devices to different VLANs based on their MAC addresses. You want to separate VoIP phones from regular PCs connected to the same unmanaged switch. This switch then connects to a single port on an EX Series switch.
Referring to the exhibit, which statement describes how you apply the MAC_BASED_VLAN filter to achieve the requested filter-based VLAN functionality for devices connecting to ge-0/0/0.0?
- A. You apply the filter to a Layer 3 IRB interface associated with the VLANs.
- B. You apply the filter to the ge-0/0/0.0 interface in the input direction under the ethernet-switching family.
- C. You apply the filter to the ge-0/0/0.0 interface in the input direction under the inet family.
- D. You apply the filter to VOIP_VLAN and DATA_VLAN under the vlans hierarchy in the input direction.
Correct Answer: B 🗳️

You must troubleshoot a multicast issue impacting streaming video quality, on an EX Series switch. Users report problems with multicast traffic, specifically audio and video traffic. You suspect that there is a class-of-service (CoS) issue with the EX Series switch configuration, specifically with the weighted random early detection (WRED). Which statement is correct in this scenario?
- A. The VLAN tag strips priority bits during ingress.
- B. The switch does not support CoS on Layer 2 interfaces.
- C. The CoS profile is dropping multicast traffic, which is sensitive to jitter and delay.
- D. The interface on the switch is configured with trust vlan rather than trust dscp.
