EX294 Implement advanced Ansible automation Practice Question
This EX294 practice question tests your understanding of implement advanced ansible automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An Ansible playbook that deploys a web application includes a task that uses the `uri` module to call an external API. The task occasionally fails due to API rate limiting. Which combination of keywords should be added to the task to automatically retry up to 5 times with a 30-second delay between attempts, and only fail if all retries are exhausted?
Option B is correct because it combines `register` to capture the API response, `until` to check that `result.status` equals 200 (the HTTP success code), `retries: 5` to attempt the task up to five times, and `delay: 30` to wait 30 seconds between retries. This ensures the task only fails after all five retries are exhausted, which is the exact behavior needed to handle transient API rate limiting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
`register: result`, `until: status == 200`, `retries: 5`, `delay: 30`
Why it's wrong here
The `until` condition should reference the registered variable, e.g., `result.status`, not just `status`.
Missing `register: result`, so `result` is undefined.
✗
`register: result`, `retries: 5`, `delay: 30`
Why it's wrong here
Missing `until`, so the task will not retry based on condition; it would only run once.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the requirement that `register` must be used with `until` to reference the captured result, and that `retries`/`delay` are meaningless without `until` — candidates frequently omit `register` or forget to prefix the variable with `result.` in the condition.
Detailed technical explanation
How to think about this question
The `uri` module returns a dictionary with keys like `status`, `json`, and `headers`; `register` stores this dictionary in a variable (e.g., `result`), which `until` then evaluates. The `retries` and `delay` keywords are only honored when `until` is defined — without it, they are ignored. In real-world scenarios, API rate limiting often returns HTTP 429 (Too Many Requests) or 503 (Service Unavailable), so checking for `status == 200` is a common pattern, but you could also check for a specific JSON field like `result.json.success == true`.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What is the correct answer to this question?
The correct answer is: `register: result`, `until: result.status == 200`, `retries: 5`, `delay: 30` — Option B is correct because it combines `register` to capture the API response, `until` to check that `result.status` equals 200 (the HTTP success code), `retries: 5` to attempt the task up to five times, and `delay: 30` to wait 30 seconds between retries.
