EX294 Implement advanced Ansible automation Practice Question
This EX294 practice question tests your understanding of implement advanced ansible automation. 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.
A playbook must execute cleanup tasks after a block of tasks, both on success and failure. Which two of the following should be used within the block to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
always
The block + always pattern ensures that a set of tasks is always executed regardless of the success or failure of tasks in the block. The block keyword groups tasks, and the always keyword defines tasks that run unconditionally. Rescue is for error handling but not required for cleanup. Ignore_errors prevents failure but does not guarantee cleanup. Failed_when customizes failure conditions.
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.
✗
ignore_errors
Why it's wrong here
ignore_errors only prevents the task from causing a failure, but does not ensure cleanup runs if other tasks fail.
✗
rescue
Why it's wrong here
rescue runs on failure but is not sufficient for cleanup on success.
✗
failed_when
Why it's wrong here
failed_when defines custom failure conditions but does not ensure cleanup.
✓
always
Why this is correct
always runs after the block regardless of outcome, ensuring cleanup.
Related concept
Static NAT maps one inside address to one outside address.
✓
block
Why this is correct
block groups tasks and is necessary to define always and rescue sections.
Related concept
Static NAT maps one inside address to one outside address.
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.
