The answer is an access port. This is the correct choice because an access port is designed to connect end devices like user PCs that send and receive untagged Ethernet frames, with the switch automatically assigning the traffic to a single configured VLAN. In contrast, a trunk port expects and handles VLAN tags to carry multiple VLANs across a link, which would confuse a standard PC that does not understand tagging. On the CCNA 200-301 v2 exam, this concept tests your understanding of switchport modes and how VLAN tagging applies at the edge of the network; a common trap is assuming a trunk is needed for any device, but remember that only infrastructure links between switches or routers require tagging. For a quick memory tip, think “access for a single address, trunk for a truckload of VLANs.”
CCNA Switching and Network Access Practice Question
This 200-301 practice question tests your understanding of switching and network access. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. A key principle to apply: an access port on a Cisco switch forwards untagged Ethernet frames and associates them with a single VLAN configured on that port.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A port connected to an end-user PC should not send or expect VLAN tags from the endpoint. Which interface type is appropriate on the switch?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Access port
The appropriate interface type is an access port. In plain language, a normal user PC is expected to connect to one VLAN and send ordinary untagged Ethernet frames. The switch associates that traffic with the configured access VLAN. This is different from a trunk, which is designed to carry multiple VLANs and commonly uses tagging to preserve VLAN identity across the link. Routed ports are Layer 3 interfaces used for routing between VLANs, not for attaching a single end-user PC. Port-channel interfaces aggregate multiple physical links for redundancy and bandwidth, but they do not determine whether VLAN tagging is used; the underlying port mode (access or trunk) still applies. Therefore, access port is the only correct choice for an untagged, single-VLAN end-device connection.
Key principle: An access port on a Cisco switch forwards untagged Ethernet frames and associates them with a single VLAN configured on that port.

✓
Access port
Why this is correct
This is correct because an access port is the normal single-VLAN switchport type for end devices such as PCs.
Related concept
An access port on a Cisco switch forwards untagged Ethernet frames and associates them with a single VLAN configured on that port.
✗
Trunk port
Why it's wrong here
This is wrong because trunks are intended to carry multiple VLANs and use tagging not normally expected from a PC.
When this WOULD be correct
If the exam question specified a scenario where multiple VLANs need to be transmitted between switches or to a router, and the focus was on inter-switch communication rather than end-user devices, then a trunk port would be the correct answer.
✗
Routed port
Why it's wrong here
This is wrong because a routed port is a Layer 3 interface, not the usual design for a user PC access connection.
When this WOULD be correct
In a scenario where the question asks for the appropriate interface type for connecting two routers or Layer 3 devices that need to communicate without VLAN tagging, a routed port would be the correct answer, as it allows for direct IP communication between devices.
✗
Port-channel interface
Why it's wrong here
This is wrong because EtherChannel interfaces are for bundling multiple links.
When this WOULD be correct
If the exam question asked about configuring a switch to connect multiple access ports for redundancy and load balancing, where VLAN tagging is not required, then a port-channel interface would be the correct answer. The question would need to focus on link aggregation rather than VLAN handling.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓Access portCorrect answer▾
Why this is correct
This is correct because an access port is the normal single-VLAN switchport type for end devices such as PCs.
✗Trunk portWrong answer — click to see why▾
Why this is wrong here
A trunk port is designed to carry traffic for multiple VLANs using 802.1Q tagging, which is not expected from a standard PC. Using a trunk port for a PC would cause the switch to expect tagged frames, leading to communication failures.
★ When this WOULD be the correct answer
If the exam question specified a scenario where multiple VLANs need to be transmitted between switches or to a router, and the focus was on inter-switch communication rather than end-user devices, then a trunk port would be the correct answer.
Why candidates choose this
Students might confuse trunk ports with the ability to carry multiple VLANs, but they forget that end devices typically do not send or understand VLAN tags.
✗Routed portWrong answer — click to see why▾
Why this is wrong here
A routed port is a Layer 3 interface used for routing between VLANs or connecting to routers, not for connecting end-user PCs. It does not operate as a Layer 2 switchport and would not handle VLAN tagging as required.
★ When this WOULD be the correct answer
In a scenario where the question asks for the appropriate interface type for connecting two routers or Layer 3 devices that need to communicate without VLAN tagging, a routed port would be the correct answer, as it allows for direct IP communication between devices.
Why candidates choose this
Some may think a routed port can be used for any connection, but it lacks the Layer 2 switching functionality needed for a PC access connection.
✗Port-channel interfaceWrong answer — click to see why▾
Why this is wrong here
A port-channel interface is a logical bundling of multiple physical links for increased bandwidth and redundancy, not a single connection to an end-user PC. It is used between switches or to servers, not for typical PC access.
★ When this WOULD be the correct answer
If the exam question asked about configuring a switch to connect multiple access ports for redundancy and load balancing, where VLAN tagging is not required, then a port-channel interface would be the correct answer. The question would need to focus on link aggregation rather than VLAN handling.
Why candidates choose this
Students might associate port-channels with any type of connection, but they are not appropriate for a simple PC connection where no link aggregation is needed.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Don't confuse the need for VLANs with the need for VLAN tagging. Access ports handle untagged traffic for single VLANs.
Detailed technical explanation
How to think about this question
In Cisco switching, an access port is a Layer 2 interface configured to carry traffic for a single VLAN. It accepts untagged Ethernet frames from connected end devices, such as PCs, and associates all incoming traffic with the configured access VLAN. This design simplifies VLAN management for user devices, which typically do not understand or generate VLAN tags. Access ports strip VLAN tags from outgoing frames and do not expect tags on incoming frames, ensuring compatibility with standard Ethernet endpoints.
The decision to configure a switchport as an access port versus a trunk port depends on the connected device type and VLAN requirements. Access ports are appropriate for end-user devices that belong to a single VLAN, while trunk ports carry multiple VLANs simultaneously by tagging frames with IEEE 802.1Q VLAN identifiers. Routed ports differ as they operate at Layer 3, providing IP routing capabilities rather than VLAN switching. Port-channel interfaces aggregate multiple physical links but do not inherently determine VLAN tagging behavior.
A common exam trap is confusing access ports with trunk ports due to the association of VLANs with both. Candidates may incorrectly select trunk ports, assuming VLAN tagging is always necessary. However, trunk ports expect and send tagged frames, which end-user PCs do not generate or process. Understanding that access ports handle untagged frames and assign them to a VLAN internally is crucial. Practically, misconfiguring a PC port as a trunk can cause connectivity issues, as the PC will not communicate properly with tagged traffic.
KKey Concepts to Remember
An access port on a Cisco switch forwards untagged Ethernet frames and associates them with a single VLAN configured on that port.
Trunk ports carry multiple VLANs by tagging frames with 802.1Q VLAN identifiers and expect tagged frames from connected devices.
End-user devices like PCs typically do not generate or process VLAN tags, so their switch ports must be configured as access ports.
Routed ports operate at Layer 3 and provide IP routing functions, making them unsuitable for direct end-user device connections requiring VLAN tagging.
Port-channel interfaces bundle multiple physical links for increased bandwidth but do not inherently manage VLAN tagging behavior for end devices.
Configuring a PC-facing switchport as a trunk port can cause connectivity failures because the PC does not handle VLAN tags.
Access ports simplify VLAN management by internally associating untagged frames with a single VLAN without requiring endpoint VLAN awareness.
The correct switchport type for connecting an end-user PC is an access port to ensure proper VLAN assignment and untagged frame handling.

Key takeaway
An access port on a Cisco switch forwards untagged Ethernet frames and associates them with a single VLAN configured on that port.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
