AZ-400 Design and implement source control Practice Question
This AZ-400 practice question tests your understanding of design and implement source control. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The pipeline will not trigger because the branch is excluded.
The trigger includes main and release/* branches, and explicitly excludes feature/* branches. Since 'feature/new-login' matches the exclude pattern 'feature/*', the pipeline will not trigger. The pipeline will only trigger for branches that match include patterns and do not match exclude patterns. 'feature/new-login' is excluded, so no build will start.
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.
✗
The pipeline will trigger and run all steps because the branch name does not match any exclude pattern.
Why it's wrong here
The branch does match the exclude pattern 'feature/*'.
✓
The pipeline will not trigger because the branch is excluded.
Why this is correct
The exclude pattern 'feature/*' prevents triggering on any branch starting with 'feature/'.
Related concept
Static NAT maps one inside address to one outside address.
✗
The pipeline will trigger only the restore and build steps, skipping tests.
Why it's wrong here
No steps will run because the pipeline does not trigger.
✗
The pipeline will trigger but fail with an error because the branch is not in the include list.
Why it's wrong here
The pipeline will not trigger at all due to the exclude rule.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

What is the correct answer to this question?
The correct answer is: The pipeline will not trigger because the branch is excluded. — The trigger includes main and release/* branches, and explicitly excludes feature/* branches. Since 'feature/new-login' matches the exclude pattern 'feature/*', the pipeline will not trigger. The pipeline will only trigger for branches that match include patterns and do not match exclude patterns. 'feature/new-login' is excluded, so no build will start.
