200-901 Software Development and Design Practice Question

This 200-901 practice question tests your understanding of software development and design. 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.

Exhibit

---
- name: Configure VLAN
  hosts: switches
  tasks:
    - name: Create VLAN 10
      cisco.ios.ios_vlan:
        vlan_id: 10
        name: voice
        state: present

Refer to the exhibit. What will be the result of running this Ansible playbook against the 'switches' group?

Exhibit

---
- name: Configure VLAN
  hosts: switches
  tasks:
    - name: Create VLAN 10
      cisco.ios.ios_vlan:
        vlan_id: 10
        name: voice
        state: present

A
VLAN 10 will be deleted
Why wrong: Deletion requires 'state: absent'.
B
VLAN 10 will be modified to have the name 'voice'
Why wrong: Modification will happen if VLAN exists, but the primary action is creation; the wording 'will be modified' is not the best description for a 'present' state.
C
The playbook will only show the running configuration of VLAN 10
Why wrong: The task does not include any show command; it directly configures the device.
D
VLAN 10 will be created if it does not already exist
The 'state: present' parameter ensures the VLAN is present; Ansible will create it if missing.

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

✓

VLAN 10 will be created if it does not already exist

Option A is correct because the task uses the 'state: present' parameter to ensure VLAN 10 exists. Option B (deletion) would require 'state: absent'. Option C (modification) would apply only if the VLAN already exists with different attributes, but the task is idempotent. Option D is incorrect because the playbook does not show configuration. Therefore, the primary outcome is creating VLAN 10 if it does not exist.

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.

✗
VLAN 10 will be deleted
Why it's wrong here
Deletion requires 'state: absent'.
✗
VLAN 10 will be modified to have the name 'voice'
Why it's wrong here
Modification will happen if VLAN exists, but the primary action is creation; the wording 'will be modified' is not the best description for a 'present' state.
✗
The playbook will only show the running configuration of VLAN 10
Why it's wrong here
The task does not include any show command; it directly configures the device.
✓
VLAN 10 will be created if it does not already exist
Why this is correct
The 'state: present' parameter ensures the VLAN is present; Ansible will create it if missing.
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.

Trap categories for this question

Command / output trap
The task does not include any show command; it directly configures the device.

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 200-901 questions on switching, trunking, and access-port configuration.
