Quick Answer
The answer is ios_l3_interfaces, which configures Layer 3 interface properties such as IP addresses and encapsulation. This is correct because the cisco.ios Ansible modules are purpose-built for specific network automation tasks: ios_config pushes raw configuration commands to the device, ios_command executes show commands and retrieves output, ios_facts gathers device facts like hardware and software details, ios_vlans manages VLAN creation and deletion, and ios_l3_interfaces specifically handles Layer 3 interface attributes like IP addressing and routing protocol assignments. On the ENCOR 350-401 exam, this drag-and-drop question tests your ability to match each module to its exact function, a common trap being confusion between ios_config and ios_l3_interfaces—remember that ios_config is a generic command pusher, while ios_l3_interfaces is a structured module for Layer 3 interfaces only. A helpful memory tip is to think of the “L3” in the module name as a direct cue for “Layer 3,” so when you see an interface IP address or OSPF network statement, ios_l3_interfaces is your answer.
350-401 Ansible Automation Practice Question
This 350-401 practice question tests your understanding of ansible automation. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 each cisco.ios module on the left to its matching purpose on the right.

Correct answer & explanation
✓
ios_config: Pushes configuration commands to Cisco IOS devices
ios_config pushes configuration commands; ios_command executes show commands; ios_facts gathers device facts; ios_vlans manages VLAN configuration; ios_l3_interfaces configures Layer 3 interfaces.
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.
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.
What to study next
Got this wrong? Here's your next step.
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related 350-401 questions on switching, trunking, and access-port configuration.

Variation 1. Drag and drop each cisco.ios module on the left to its matching purpose on the right.
medium- ✓ P1.ios_config: Push configuration commands to Cisco IOS devices
- ✓ P2.ios_command: Execute show and exec commands on Cisco IOS devices
- ✓ P3.ios_facts: Collect device facts such as version, interfaces, and serial numbers
