350-601 Automation Practice Question
Exhibit
- name: Apply VLAN configuration to Nexus switches\n hosts: nexus_switches\n gather_facts: no\n tasks:\n - name: Configure VLAN 10\n cisco.nxos.nxos_config:\n lines:\n - vlan 10\n - name Automation_VLAN\n provider: "{{ cli }}"Refer to the exhibit. What is the intended effect of this Ansible playbook task?
⚠ Common exam trap
Cisco often tests the distinction between `merged`, `replaced`, `overridden`, and `deleted` states in Ansible modules, and the trap here is that candidates mistakenly associate any configuration task with a reboot or save operation, or assume `merged` implies deletion of existing configuration.

Correct answer & explanation
✓
It ensures VLAN 10 exists with the name 'Automation_VLAN' on the target switches.
The Ansible playbook task uses the `cisco.nxos.nxos_vlans` module with the `state: merged` directive, which ensures that the specified VLAN configuration (VLAN 10 with name 'Automation_VLAN') is present on the target Nexus switches. If VLAN 10 does not exist, it will be created; if it exists with a different name, it will be updated. The `merged` operation does not delete or reboot; it only applies the configuration to align the device's state with the playbook's desired state.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It deletes VLAN 10 from all switches.
Why it's wrong here
The task is adding lines, not deleting; no negate statement.
- ✗
It saves the running configuration to startup.
Why it's wrong here
Saving requires a separate task or parameter (save: yes).
- ✗
It reboots the Nexus switches after applying the configuration.
Why it's wrong here
No reboot is triggered; it only configures VLAN.
- ✓
It ensures VLAN 10 exists with the name 'Automation_VLAN' on the target switches.
Why this is correct
The nxos_config module pushes the provided lines, ensuring they are present.
