DOP-C02 SDLC Automation Practice Question
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 are valid deployment configurations in AWS CodeDeploy? (Choose two.)
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
✓
AllAtOnce
In AWS CodeDeploy, the valid deployment configurations are predefined traffic-shifting strategies. 'AllAtOnce' is a valid configuration that deploys the new application revision to all instances simultaneously, making it one of the two correct options. 'Canary10Percent5Minutes' is also a valid configuration that shifts 10% of traffic to the new version for 5 minutes before deploying the remainder, making it the second correct option.
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
The trap here is that candidates confuse deployment types (like BlueGreen or Rolling) with deployment configurations (like AllAtOnce or Canary10Percent5Minutes), leading them to select 'BlueGreen' or 'Rolling' as valid configurations when they are actually deployment methods or strategies in other AWS services.
Detailed technical explanation
How to think about this question
AWS CodeDeploy deployment configurations are defined by the 'DeploymentConfigName' parameter, which can be a predefined name like 'CodeDeployDefault.AllAtOnce' or 'CodeDeployDefault.Canary10Percent5Minutes'. These configurations control the rate of traffic shifting to the new revision during a deployment. For canary and linear configurations, the naming convention includes the percentage and time interval (e.g., Canary10Percent5Minutes shifts 10% for 5 minutes, then the remaining 90% immediately), while AllAtOnce shifts 100% immediately. Understanding this naming pattern is critical for selecting valid options in the exam.
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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
