Trunk Port
A type of port assigned to carry traffic from all the VLANs connected to a specific network switch is known as: Default gateway Trunk port Registered port Mirrored port

True
The term "Default route" refers to a "last resort" network path used by a router for forwarding all packets with destination addresses not listed in its routing table. True False
True
To allow traffic from multiple VLANs on a single communication link, frames from individual VLANs must be identified. The most common and preferred method, IEEE 802.1Q, adds a tag to the Ethernet frame header, labeling it as belonging to a certain VLAN. True False
