350-401 Practice Question: Which two statements about Ansible modules and…
Which two statements about Ansible modules and idempotency are true? (Choose two.)
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
✓
Idempotency means that running a playbook multiple times will always result in the same final state on the managed node.
Ansible modules are designed to be idempotent, meaning repeated runs produce the same state. The 'command' and 'shell' modules are not idempotent by default. Modules like 'copy' and 'template' check current state before making changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Idempotency means that running a playbook multiple times will always result in the same final state on the managed node.
Why this is correct
Correct because idempotency ensures that repeated application of the same configuration does not change the system beyond the desired state.
- ✗
The 'command' module is idempotent by default because it always runs the given command.
Why it's wrong here
Incorrect because the 'command' module is not idempotent; it executes the command every time without checking if the desired state already exists.
- ✓
The 'copy' module is idempotent because it checks the checksum of the destination file before copying.
Why this is correct
Correct because the 'copy' module compares the source and destination file checksums and only copies if they differ, making it idempotent.
- ✗
All Ansible modules are inherently idempotent regardless of how they are implemented.
Why it's wrong here
Incorrect because not all modules are idempotent; for example, 'command' and 'shell' modules execute every time unless the user adds a 'creates' or 'when' condition.
- ✗
Idempotency only applies to network modules, not to Linux system modules.
Why it's wrong here
Incorrect because idempotency is a general design principle for all Ansible modules, including both network and system modules.
