Question 102 of 724
DVA-C02 Deployment Practice Question
A developer is using AWS CodePipeline with multiple actions in a stage. The pipeline has a build action that produces artifacts, followed by a deploy action. The developer wants to ensure that if the deploy action fails, the pipeline stops and does not continue to the next stage. How can they achieve this?
⚠ Common exam trap
The trap here is that candidates may overthink and assume they need to configure a special failure behavior, when in fact the default sequential pipeline execution already stops on any action failure.
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
✓
No additional configuration is needed; the pipeline stops on failure by default.
AWS CodePipeline stages are sequential by default: if any action within a stage fails, the entire stage fails and the pipeline stops, preventing execution of subsequent stages. No additional configuration is needed to halt the pipeline on a deploy action failure, as this is the inherent behavior of a pipeline stage with multiple actions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure the deploy action to 'Abort' on failure.
Why it's wrong here
Configuring a CodePipeline action with an explicit 'Abort' on failure setting is not a valid or available option within the AWS CodePipeline service. CodePipeline actions do not expose a direct configuration parameter to dictate their individual failure response in this manner. Instead, the pipeline itself has an inherent default behavior to halt the entire execution upon any action failure, preventing subsequent stages from running.
- ✗
Set the runOrder for the deploy action to 'Blocked'.
Why it's wrong here
The `runOrder` parameter in AWS CodePipeline is used to specify the sequential execution order of actions *within the same stage*, not to control how the pipeline reacts to a failure. It accepts an integer value, determining which action runs first, second, and so on, if multiple actions are configured in a stage. Setting `runOrder` to a non-numeric value like 'Blocked' is invalid and would not influence the pipeline's default failure handling mechanism.
- ✓
No additional configuration is needed; the pipeline stops on failure by default.
Why this is correct
AWS CodePipeline is designed to inherently stop the entire pipeline execution immediately upon the failure of any action within any stage. This default behavior is crucial for maintaining the integrity of the CI/CD process, preventing the deployment of potentially faulty code or artifacts to subsequent environments. No explicit configuration is required to enable this safety mechanism, as it is a fundamental aspect of CodePipeline's operational design.
- ✗
Set the pipeline's execution mode to 'PARALLEL'.
Why it's wrong here
The `executionMode` parameter for an AWS CodePipeline primarily dictates how multiple *pipeline executions* are handled concurrently, such as allowing parallel runs of different source changes. Setting it to 'PARALLEL' enables multiple pipeline executions to proceed simultaneously, rather than queuing them up. This configuration has no direct impact on how a *single* pipeline execution responds when one of its constituent actions fails; the default stop-on-failure behavior remains unaffected regardless of the execution mode.
