Example question from this objective
Each option is explained, so the reasoning behind the distractors is part of the answer.
A link between two switches must carry VLANs 10, 20, and 30 over the same physical interface. Which configuration type is required?
- A shutdown interface.
- A loopback interface with no switchport settings.
- A single access port in VLAN 10 only.
- An 802.1Q trunk port.
A shutdown interface. — A shutdown interface is administratively disabled and cannot carry VLAN traffic.
A loopback interface with no switchport settings. — A loopback interface is logical Layer 3 reachability and is not used as a switch trunk.
A single access port in VLAN 10 only. — An access port carries one VLAN and would not carry VLANs 10, 20, and 30 together.
An 802.1Q trunk port. — An 802.1Q trunk can carry traffic for multiple VLANs across one physical link.
