- A
Configure the pipeline source stage to trigger on all branches, use branch-specific logic in the test stage, and add a manual approval step for production deployment only when the branch is 'main'.
Branch filtering in source stage and conditional deployment is the recommended approach.
- B
Use an AWS Lambda function to check the branch name and invoke different CodePipeline executions for testing and deployment.
Why wrong: Complex and not as straightforward as built-in branch filtering.
- C
Create one pipeline with two source stages: one for 'main' and one for all other branches, each with its own test and deploy actions.
Why wrong: Pipeline stages are sequential; cannot have two source stages for different branches in same pipeline.
- D
Create a separate pipeline for each branch, each with identical test and deploy stages.
Why wrong: Managing many pipelines is inefficient and error-prone.
DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc 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 DevOps team uses AWS CodePipeline with a multi-branch strategy. The pipeline should deploy to production only from the 'main' branch, but run unit tests for all branches. How should the team configure the pipeline?
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
Configure the pipeline source stage to trigger on all branches, use branch-specific logic in the test stage, and add a manual approval step for production deployment only when the branch is 'main'.
Option C is correct because CodePipeline can use branch filtering in the source stage to trigger on specific branches, and the test stage can be configured to run for all branches. Option A is wrong because a single pipeline cannot have dynamic branch-based stages without multiple pipelines. Option B is wrong because separate pipelines per branch would duplicate effort. Option D is wrong because Lambda triggers are not the standard way to implement branch-based logic; branch filtering is native.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.
