Question 426 of 528
Ansible Forks — Parallelism Configuration
This EX294 practice question tests your understanding of manage task execution and roles. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 ansible.cfg setting controls the number of parallel forks for task execution?

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
✓
forks
The `forks` setting in `ansible.cfg` (or the `ANSIBLE_FORKS` environment variable) controls the maximum number of parallel processes Ansible uses when executing tasks on remote hosts. By default, this value is 5, meaning Ansible will manage up to 5 hosts concurrently per playbook run. Increasing this value allows Ansible to operate on more hosts simultaneously, improving throughput in larger environments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Ansible's `forks` with generic terms like `parallel` or `threads`, or with similar settings from other configuration management tools, leading them to select a plausible-sounding but incorrect option.
Detailed technical explanation
How to think about this question
Ansible's `forks` setting directly determines the size of the worker process pool created by the `ansible-runner` or `ansible-playbook` command. Each fork is a separate Python process that manages the connection and task execution for a single host. Under the hood, Ansible uses the `multiprocessing` library to spawn these forks, and the `forks` value caps the number of simultaneous child processes. In real-world scenarios, setting `forks` too high (e.g., 500 on a control node with limited resources) can overwhelm the control node's CPU or memory, leading to connection timeouts or degraded performance, so it must be balanced against the inventory size and control node capacity.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the EX294 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.
