- A
Increase the deployment timeout in the Elastic Beanstalk environment
Why wrong: Longer timeout does not prevent starting a new deployment while another is running
- B
Disable rolling updates in the Elastic Beanstalk environment
Why wrong: Disabling rolling updates may cause downtime and does not prevent concurrency

Configure a 'Wait for Environment to be Ready' action before the deploy stage
This action checks the environment status and waits until it's ready

Create multiple Elastic Beanstalk environments for blue/green deployment
Why wrong: Multiple environments add cost and management overhead

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 company uses AWS CodePipeline to deploy a web application to an Elastic Beanstalk environment. The pipeline has a source stage (S3), a build stage (CodeBuild), and a deploy stage (Elastic Beanstalk). Recently, the deployment started failing with the error 'The Elastic Beanstalk environment is not in a ready state'. The team found that the environment was in an 'Updating' state because a previous deployment was still in progress. They need a solution that prevents concurrent deployments and ensures that the environment is ready before starting a new deployment. Which action should the DevOps engineer take?
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 a 'Wait for Environment to be Ready' action before the deploy stage
To prevent concurrent deployments, the pipeline should check that the Elastic Beanstalk environment is in a ready state before starting a new deployment. AWS CodePipeline provides a built-in 'Wait for Environment to be Ready' action that polls the environment status and waits until it is ready, preventing deployment attempts when the environment is updating. Option C is correct. Option A (increasing timeout) does not prevent concurrent deployments; it only extends the wait time. Option B (disabling rolling updates) does not address concurrency and may cause downtime. Option D (creating multiple environments) adds unnecessary complexity and is not the simplest solution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
