Quick Answer
The answer is `nxos_vlan`, `nxos_config`, and `nxos_command`. These three modules are the core Ansible modules for managing NX-OS configuration because they are part of the dedicated `cisco.nxos` collection, built specifically for Nexus switches. The `nxos_config` module applies configuration snippets directly, `nxos_vlan` handles VLAN provisioning, and `nxos_command` executes show commands for verification. On the Cisco DCCOR 350-601 exam, this question tests your ability to distinguish platform-specific modules—a common trap is confusing `ios_config` (for IOS/IOS-XE) with `nxos_config`, so remember that any module prefixed with `nxos_` targets NX-OS only. For a quick memory tip, think "NX for Nexus" and avoid any module starting with `ios_` when working with Nexus switches.
This 350-601 practice question tests your understanding of automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A network automation engineer is writing an Ansible playbook to configure Nexus switches. Which three modules are available to manage NX-OS configuration? (Choose three.)
eos_config
Why wrong: Module for Arista EOS, not NX-OS.
nxos_config
Manages NX-OS configuration.
nxos_interface
Manages interfaces on NX-OS.
nxos_vlan
Manages VLANs on NX-OS.
ios_config
Why wrong: Module for Cisco IOS, not NX-OS.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
nxos_config
The `nxos_config` module is the primary Ansible module for managing NX-OS device configurations, allowing you to apply, replace, or merge configuration snippets directly onto Nexus switches. It is part of the `cisco.nxos` collection and is specifically designed for NX-OS, unlike `ios_config` which targets Cisco IOS/IOS-XE devices.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the distinction between platform-specific Ansible modules (e.g., `nxos_*` vs `ios_*` vs `eos_*`), and the trap here is that candidates may confuse `ios_config` as being compatible with NX-OS due to a superficial similarity in CLI syntax, ignoring the underlying platform-specific module requirements.
Detailed technical explanation
Under the hood, `nxos_config` leverages the NX-API or SSH to push configuration commands, supporting features like `backup`, `diff`, and `replace` operations that align with NX-OS's atomic configuration model. In a real-world scenario, using `nxos_interface` and `nxos_vlan` alongside `nxos_config` allows granular interface and VLAN management, while `nxos_config` handles bulk or idempotent configuration changes, reducing playbook complexity.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
