This 200-901 practice question tests your understanding of infrastructure and 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.
Which TWO Ansible modules are commonly used for automating Cisco IOS devices?
junos_config
Why wrong: For Juniper Junos.
nxos_command
Why wrong: For NX-OS devices.
ios_config
Manages Cisco IOS configuration.
ios_command
Sends Cisco IOS commands.
eos_config
Why wrong: For Arista EOS.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ios_config
The `ios_config` module is correct because it is specifically designed to manage Cisco IOS device configurations by sending configuration commands via SSH or Telnet, using the CLI to apply changes to the running or startup configuration. This module is part of Ansible's `cisco.ios` collection and directly supports the IOS operating system, making it the standard choice for automating configuration tasks on Cisco IOS 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 candidate's ability to distinguish between device-specific Ansible modules (e.g., `ios_config` vs. `nxos_command`) rather than generic command modules, so the trap here is assuming that any 'command' module works across all Cisco platforms, when in fact each OS family (IOS, NX-OS, IOS-XR) has its own dedicated modules in the Ansible collections.
Detailed technical explanation
Under the hood, `ios_config` uses the `cli` transport (SSH) to send configuration commands to the device, automatically entering global configuration mode and handling command idempotency by comparing the desired state against the current running configuration. A subtle behavior is that it supports `parents` to specify the configuration context (e.g., interface subcommands) and can use `match` and `replace` directives to control how configuration lines are applied, which is critical for avoiding unintended changes in large-scale deployments.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
