200-901 Infrastructure and Automation Practice Question

Exhibit

Refer to the exhibit.

---
- name: Configure interface description
  hosts: cisco_devices
  gather_facts: no
  tasks:
    - name: Set description
      ios_config:
        lines:
          - description Configured by Ansible
        parents: interface GigabitEthernet0/1

Refer to the exhibit. An Ansible playbook is intended to set the description on GigabitEthernet0/1. However, the playbook fails because the device does not have that interface. What is the most likely reason?

⚠ Common exam trap

Cisco often tests the distinction between a syntactically correct playbook and a playbook that fails due to device-specific constraints, such as a non-existent interface, to see if candidates confuse configuration syntax errors with device state issues.

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

✓

The specified interface does not exist on the device

The playbook explicitly targets GigabitEthernet0/1 using the `interface` attribute under `lines`, and the error indicates the device does not have that interface. Ansible's ios_config module will fail if the specified interface does not exist on the device, as it cannot apply configuration to a non-existent logical or physical interface.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The module requires gather_facts to be yes
Why it's wrong here
gather_facts is not required for ios_config.
✗
The hosts group is incorrect
Why it's wrong here
If hosts were incorrect, the playbook would not run on any device, but the error is likely interface-specific.
✗
The lines attribute is misconfigured
Why it's wrong here
The lines syntax is correct for setting description.
✓
The specified interface does not exist on the device
Why this is correct
If the interface is not present, the module cannot apply configuration under it.
