A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs.
Refer to the exhibit. How did the router obtain the last route that is shown?
Another router in the same organization provided the default route by using a dynamic routing protocol.
Refer to the exhibit. The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network.
