350-601 Automation Practice Question
An Ansible playbook using the cisco.nxos.nxos_config module fails with the error: 'Unsupported parameters for (cisco.nxos.nxos_config) module: connection type setting'. What is the most likely cause?
⚠ Common exam trap
Cisco often tests the distinction between play-level and task-level parameters, specifically that `connection` is not a valid parameter for network modules at the task level, leading candidates to incorrectly attribute the error to module installation or device compatibility.
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 playbook includes an invalid parameter 'connection: network_cli' inside the task block.
The error 'Unsupported parameters for (cisco.nxos.nxos_config) module: connection type setting' occurs because the `connection: network_cli` parameter is being passed inside the task block of the playbook. The `cisco.nxos.nxos_config` module does not accept a `connection` parameter at the task level; connection settings must be defined at the play or inventory level. This is a common syntax error when using Ansible network modules.
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 SSH key authentication is misconfigured.
Why it's wrong here
Authentication issues cause connection errors, not parameter unsupported errors.
- ✓
The playbook includes an invalid parameter 'connection: network_cli' inside the task block.
Why this is correct
The 'connection' parameter is a play-level attribute, not a task parameter for nxos_config.
- ✗
The module is not installed correctly.
Why it's wrong here
A missing module would give a different error, not about unsupported parameters.
- ✗
The playbook is targeting a device running an unsupported NX-OS version.
Why it's wrong here
Version unsupported would cause connection or execution errors, not parameter errors.
