EX294 Manage automation security and operations Practice Question
This EX294 practice question tests your understanding of manage automation security and operations. 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 managed node is not responding to Ansible automation. The administrator verifies that the node is reachable via SSH and that the SSH key is correctly deployed. However, 'ansible all -m ping' fails with 'UNREACHABLE'. The automation controller uses a custom execution environment. What 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The custom execution environment is missing the 'python3' or 'python' package.
Option C is correct because the custom execution environment is a container image that must contain the Python interpreter (python3 or python) for Ansible to execute modules on the managed node. When the environment lacks Python, the 'ansible -m ping' module cannot be transferred and executed, resulting in an 'UNREACHABLE' status despite SSH connectivity being verified.
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.
✗
The SSH private key has incorrect permissions on the controller.
Why it's wrong here
The administrator verified the SSH key is correctly deployed.
✗
The remote user specified in the credential does not have sudo access.
Why it's wrong here
The ping module does not require sudo.
✓
The custom execution environment is missing the 'python3' or 'python' package.
Why this is correct
Ansible requires Python on the control node (execution environment) to execute modules; missing Python causes unreachable errors.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The automation controller is behind a firewall that blocks SSH.
Why it's wrong here
The administrator verified the node is reachable via SSH, so firewall is not blocking.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume 'UNREACHABLE' always indicates a network or SSH issue, but EX294 tests the understanding that Ansible requires Python on the managed node, and a custom execution environment may lack it, causing a false unreachable status.
Detailed technical explanation
How to think about this question
Ansible's 'ping' module does not use ICMP; it connects via SSH, transfers a small Python script to the managed node, and executes it to verify Python availability. In a custom execution environment (e.g., a containerized Ansible runner), the controller's Python is isolated, and the environment must include the Python interpreter and dependencies (like python3-selinux) for module execution. If the environment is minimal (e.g., a distroless image), Python may be absent, causing the module to fail silently with 'UNREACHABLE' even though SSH transport succeeds.
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.
