- A
switchport mode trunk: Configures an interface to carry multiple VLANs.
This command configures a switch port as an access port, which belongs to a single VLAN and carries traffic for that VLAN only.
- B
switchport access vlan 10: Assigns an interface to a specific VLAN.
This command configures a port as a trunk port, which carries traffic for multiple VLANs. However, it is not the command that configures an access port.
- C
native VLAN: The VLAN that carries untagged traffic on a trunk link.
The native VLAN is a concept on trunk ports where untagged frames are assigned to a specific VLAN. It is not a command or a term that describes an access port.
- D
VLAN 1: Default VLAN on Cisco switches; often recommended to change.
VLAN 1 is the default VLAN on Cisco switches, but it is not a command or a term that configures an access port. It is a specific VLAN number.
CCNA Switching and Network Access Practice Question
This 200-301 practice question tests your understanding of switching and network access. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
Drag and drop the VLAN/trunking commands and terms on the left to their correct descriptions or functions on the right.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
switchport mode trunk: Configures an interface to carry multiple VLANs.
These pairings match common VLAN/trunking commands and terms to their correct descriptions.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
switchport mode trunk: Configures an interface to carry multiple VLANs.
Why this is correct
This command configures a switch port as an access port, which belongs to a single VLAN and carries traffic for that VLAN only.
Related concept
Access ports place end devices into a single VLAN.
- ✓
switchport access vlan 10: Assigns an interface to a specific VLAN.
Why this is correct
This command configures a port as a trunk port, which carries traffic for multiple VLANs. However, it is not the command that configures an access port.
Related concept
Access ports place end devices into a single VLAN.
- ✓
native VLAN: The VLAN that carries untagged traffic on a trunk link.
Why this is correct
The native VLAN is a concept on trunk ports where untagged frames are assigned to a specific VLAN. It is not a command or a term that describes an access port.

Why this is correct
VLAN 1 is the default VLAN on Cisco switches, but it is not a command or a term that configures an access port. It is a specific VLAN number.
Related concept
Access ports place end devices into a single VLAN.
Common exam traps
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
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.
