CompTIA Network+ (N10-009)Network ImplementationEasy
A technician is connecting a single desktop printer to a switch port. The printer only needs access to VLAN 10 and does not require multiple VLAN tags. How should the technician configure this switch port?
- AAs a trunk port carrying all VLANs
- BAs a dynamic desirable trunk port
- CAs a native VLAN port with tagging enabled
- DAs an access port assigned to VLAN 10
Show answer & explanationAnswer & explanation
Correct answer: D. As an access port assigned to VLAN 10
A single end device that only needs to communicate on one VLAN should be connected to an access port, which is statically assigned to that one VLAN and sends/receives untagged frames.
Why the other options are wrong
- A. A trunk carries multiple VLANs and is meant for switch-to-switch or switch-to-router links, not single-VLAN end devices.
- B. Dynamic desirable is a DTP trunking negotiation mode, unnecessary for a single-VLAN printer.
- C. Native VLAN applies to trunk ports for untagged traffic, not standard access ports.
Access Port
A switch port configured to belong to a single VLAN, sending and receiving untagged Ethernet frames to an end device.
- Used for end devices like PCs, printers, phones
- Contrasts with trunk ports which carry multiple tagged VLANs
- Frames on an access port are untagged
Memory trick: Access = one door, one room; Trunk = hallway with many rooms.
