- A
Run ansible-galaxy install on the control node and distribute the roles via a separate channel.
Why wrong: ansible-pull is meant to be self-contained; requiring separate distribution defeats its purpose.
- B
Add the role directories directly to the Git repository and modify the playbook to reference them with a relative path.
Why wrong: While this would work, it is not best practice and does not explain why it started failing; roles were never in the repo.
- C
Add a pre_task to the playbook that runs 'ansible-galaxy install -r requirements.yml' before the roles are used.
Correct: This ensures roles are installed from Galaxy during the pull execution.
- D
Set the 'roles_path' in ansible.cfg on each node to include the repository's roles directory.
Why wrong: The roles are not in the repository; they are external dependencies.
EX294 Manage task execution and roles Practice Question
This EX294 practice question tests your understanding of manage task execution and roles. 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.
Your team uses ansible-pull to manage configuration of a large number of remote nodes. Each node is configured to pull the latest playbook from a Git repository every 30 minutes. Recently, some nodes started reporting 'ERROR! the role 'base' was not found'. The playbook depends on roles from a requirements.yml file that is stored in the same repository. The ansible-pull command on each node uses the default roles path (~/.ansible/roles). The Git repository contains the requirements.yml file but does not contain the actual role directories. What is the most likely cause and solution?
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 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
Add a pre_task to the playbook that runs 'ansible-galaxy install -r requirements.yml' before the roles are used.
Option C is correct because ansible-pull does not automatically install roles from requirements.yml; the playbook should include a pre_task that runs 'ansible-galaxy install -r requirements.yml' before using the roles. Option A is incorrect because the roles are already in the repository? No, they are not. Option B is incorrect because ansible-pull does not use a local roles path by default; the issue is missing installation. Option D is incorrect because the control node is not involved in ansible-pull.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run ansible-galaxy install on the control node and distribute the roles via a separate channel.
Why it's wrong here
ansible-pull is meant to be self-contained; requiring separate distribution defeats its purpose.
- ✗
Add the role directories directly to the Git repository and modify the playbook to reference them with a relative path.
Why it's wrong here
While this would work, it is not best practice and does not explain why it started failing; roles were never in the repo.
- ✓
Add a pre_task to the playbook that runs 'ansible-galaxy install -r requirements.yml' before the roles are used.
Why this is correct
Correct: This ensures roles are installed from Galaxy during the pull execution.
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.
- ✗
Set the 'roles_path' in ansible.cfg on each node to include the repository's roles directory.
Why it's wrong here
The roles are not in the repository; they are external dependencies.
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.
