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.

A playbook uses the 'include_tasks' module to load platform-specific tasks. The playbook fails intermittently with 'Could not find or access file' error on some runs but works on others. Which of the following is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Question 1hardmultiple choice

Read the full Ansible explanation →

A
The 'include_tasks' is used inside a block that has 'always' section.
Why wrong: Incorrect: Using include_tasks inside a block with always does not cause intermittent file access errors.
B
The task file path is not absolute and Ansible's search order is inconsistent.
Why wrong: Incorrect: Ansible's search order is deterministic; inconsistency is unlikely.
C
The 'include_tasks' is used with a loop and the loop variable shadows the included file's parameter.
Correct: Variable shadowing can cause the included file's expected variable to be overridden, leading to file lookup failures on some iterations.
D
The playbook uses 'any_errors_fatal: true' causing early exits.
Why wrong: Incorrect: This setting causes the play to stop on any failure, but would not produce an intermittent file error.

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

✓

The 'include_tasks' is used with a loop and the loop variable shadows the included file's parameter.

Option D is correct because if the loop variable used in include_tasks shadows a parameter expected by the included file, it can cause variable collision and file resolution issues. Option A is less likely because Ansible's search order is consistent. Option B and C would cause consistent failures. Therefore, D is the most likely cause.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why this is correct
Correct: Variable shadowing can cause the included file's expected variable to be overridden, leading to file lookup failures on some iterations.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.

Why it's wrong here
Incorrect: This setting causes the play to stop on any failure, but would not produce an intermittent file error.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

Identify inside and outside interfaces first.
Check whether the scenario needs static NAT, dynamic NAT or PAT.
Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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 to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related EX294 NAT questions on configuration and troubleshooting.
