- A
The 'follow_redirects' parameter must be set to 'all' to handle HTTP 4xx and 5xx errors gracefully.
Why wrong: Incorrect: 'follow_redirects' only handles redirects, not errors.
- B
To access the response body, use the 'body' key of the registered variable and then parse it with a filter like 'json_query'.
Correct: 'body' contains the raw response body as a string.
- C
Use the 'status_code' parameter to define which HTTP response codes are considered successful.
Correct: 'status_code' specifies expected success codes.
- D
The 'failed_when' condition can inspect the HTTP response before the request is sent.
Why wrong: Incorrect: 'failed_when' is evaluated after the module runs.
- E
The 'register' keyword automatically parses JSON responses into Ansible variables.
Why wrong: Incorrect: 'body_format' must be set to 'json' for automatic parsing.
EX294 Transform data with filters and plugins Practice Question
This EX294 practice question tests your understanding of transform data with filters and plugins. 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.
When using the 'uri' module to interact with a REST API in Ansible, which TWO of the following statements about error handling and response parsing are correct?
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
To access the response body, use the 'body' key of the registered variable and then parse it with a filter like 'json_query'.
Option B is correct because when you register the result of an `uri` module call, the response body is stored under the `body` key of the registered variable. To extract or filter data from that JSON body, you can use the `json_query` filter (which relies on jmespath) to parse and query the JSON structure. This is the standard approach for accessing and manipulating API response data in Ansible.
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
Cisco often tests the misconception that `register` automatically parses JSON or that `failed_when` can run before the request, when in fact the registered variable is a raw dict and `failed_when` only evaluates after the HTTP transaction completes.
Detailed technical explanation
How to think about this question
Under the hood, the `uri` module uses Python's `requests` library to make HTTP calls. The response object includes headers, status code, and the raw body as a string. Even if the API returns JSON, Ansible treats the body as a string until you apply a filter like `json_query` or `from_json`. A subtle behavior: if the response body is empty or not valid JSON, `json_query` will fail, so you may need to use `from_json` first or handle errors with `ignore_errors`.
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.
