- A
Create VLANs, assign data and voice VLANs to the phone port, configure the AP trunk, enable PoE on the IoT port
This order follows the logical sequence: first create VLANs, then configure access ports with voice and data VLANs, then configure trunk ports for APs, and finally enable PoE for IoT devices.
- B
Enable PoE on the IoT port, create VLANs, configure the AP trunk, assign data and voice VLANs to the phone port
Why wrong: This is incorrect because PoE should be enabled after VLANs are created and ports are configured; enabling PoE first is unnecessary and out of order.
- C
Create VLANs, enable PoE on the IoT port, assign data and voice VLANs to the phone port, configure the AP trunk
Why wrong: This is incorrect because enabling PoE before configuring the phone port and AP trunk is out of order; PoE should be enabled after port configuration.
- D
Configure the AP trunk, create VLANs, assign data and voice VLANs to the phone port, enable PoE on the IoT port
Why wrong: This is incorrect because VLANs must be created before they can be assigned to ports; configuring the AP trunk before creating VLANs would result in errors.
Quick Answer
The correct order is to create VLANs, assign data and voice VLANs to the phone port, configure the AP trunk, and then enable PoE on the IoT port. This sequence is technically necessary because VLANs must exist in the switch database before they can be applied to any interface; attempting to assign a voice VLAN before creating it would result in an error. On the CCNA 200-301 v2 exam, this drag-and-drop task tests your understanding of switch port roles and the logical dependency of configuration steps, often appearing in the “Network Access” section. A common trap is to enable PoE first or to confuse the voice VLAN assignment with trunk configuration—remember that PoE is enabled by default on most Cisco switches, so the step is only needed if power has been disabled or for verification. For a quick memory tip, think “VLANs first, then ports, then power,” or use the mnemonic “Create, Assign, Trunk, Power” to lock in the order.
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. 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 following steps into the correct order to configure a switch port for a VoIP phone (voice VLAN + data VLAN), an AP trunk, and a PoE-powered IoT device.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create VLANs, assign data and voice VLANs to the phone port, configure the AP trunk, enable PoE on the IoT port
First create VLANs, then assign data and voice VLANs to the phone port, configure the AP trunk, and lastly enable PoE on the IoT port.
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.

- ✓
Create VLANs, assign data and voice VLANs to the phone port, configure the AP trunk, enable PoE on the IoT port
- ✗
Enable PoE on the IoT port, create VLANs, configure the AP trunk, assign data and voice VLANs to the phone port
Why it's wrong here
This is incorrect because PoE should be enabled after VLANs are created and ports are configured; enabling PoE first is unnecessary and out of order.
- ✗
Create VLANs, enable PoE on the IoT port, assign data and voice VLANs to the phone port, configure the AP trunk
Why it's wrong here
This is incorrect because enabling PoE before configuring the phone port and AP trunk is out of order; PoE should be enabled after port configuration.
- ✗
Configure the AP trunk, create VLANs, assign data and voice VLANs to the phone port, enable PoE on the IoT port
Why it's wrong here
This is incorrect because VLANs must be created before they can be assigned to ports; configuring the AP trunk before creating VLANs would result in errors.
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.
✓Create VLANs, assign data and voice VLANs to the phone port, configure the AP trunk, enable PoE on the IoT portCorrect answer▾
Why this is correct
This order follows the logical sequence: first create VLANs, then configure access ports with voice and data VLANs, then configure trunk ports for APs, and finally enable PoE for IoT devices.
✗Enable PoE on the IoT port, create VLANs, configure the AP trunk, assign data and voice VLANs to the phone portWrong answer — click to see why▾
Why this is wrong here
PoE configuration does not depend on VLANs, but it is typically done after basic port configuration to avoid misconfiguration.
Why candidates choose this
Candidates might think PoE should be enabled first to ensure power is available before configuring other features.
✗Create VLANs, enable PoE on the IoT port, assign data and voice VLANs to the phone port, configure the AP trunkWrong answer — click to see why▾
Why this is wrong here
The correct sequence is to configure all ports first, then enable PoE as a final step.
Why candidates choose this
Candidates might think PoE is independent and can be done anytime, but best practice is to configure ports first.
✗Configure the AP trunk, create VLANs, assign data and voice VLANs to the phone port, enable PoE on the IoT portWrong answer — click to see why▾
Why this is wrong here
VLANs must exist before they can be used on any port, whether access or trunk.
Why candidates choose this
Candidates might think trunk configuration is independent of VLAN creation, but the trunk will not function correctly without the VLANs existing.

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.
