This DOP-C02 practice question tests your understanding of sdlc automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO options are valid ways to trigger an AWS CodePipeline execution automatically?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Amazon CloudWatch Events rule that starts the pipeline on a schedule.
Amazon CloudWatch Events (now Amazon EventBridge) can be configured with a cron or rate expression to trigger an AWS CodePipeline execution on a schedule. This is a native integration that directly starts the pipeline without requiring additional compute resources or custom code.
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.
✓
Create an Amazon CloudWatch Events rule that starts the pipeline on a schedule.
Why this is correct
CloudWatch Events can trigger pipelines on a schedule.

✓
Configure an Amazon S3 event notification to invoke the pipeline.
Why this is correct
S3 events can trigger pipelines.
Related concept
Read the scenario before looking for a memorised answer.
Enable AWS CodeBuild to start the pipeline after a build.
Why it's wrong here
CodeBuild is a build service, not a trigger.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a git push (which requires a configured webhook) with a direct trigger, or assume that a manual approval step or CodeBuild can initiate the pipeline, when in fact they are actions within the pipeline or require an external event source.
Detailed technical explanation
How to think about this question
Under the hood, CodePipeline integrates with EventBridge via a default event bus; a rule with a schedule target uses the StartPipelineExecution API call. For S3 event notifications, the bucket must be configured to publish events to Amazon SNS, SQS, or Lambda, which then invokes the pipeline via a custom trigger—CodePipeline does not directly consume S3 event notifications. In real-world scenarios, teams often combine a scheduled trigger for periodic deployments with S3 event notifications for artifact uploads to avoid unnecessary pipeline runs.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
