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.
A DevOps engineer needs to deploy a serverless application using AWS CodeDeploy with a Lambda deployment group. The application uses AWS Lambda functions. The engineer wants to shift 10% of traffic to the new version initially, then gradually increase to 100%. Which deployment configuration should be used?

Correct answer & explanation
✓
CodeDeployDefault.LambdaCanary10Percent5Minutes
The requirement is to initially shift 10% of traffic to the new Lambda version and then gradually increase to 100%. CodeDeployDefault.LambdaCanary10Percent5Minutes shifts 10% of traffic immediately to the new version and, after 5 minutes, automatically shifts the remaining 90% to complete the deployment. This matches the described canary deployment pattern.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
CodeDeployDefault.LambdaAllAtOnce
Why it's wrong here
AllAtOnce shifts all traffic immediately.
- ✓

- ✗
CodeDeployDefault.LambdaCanary10Percent10Minutes
Why it's wrong here

- ✗
CodeDeployDefault.LambdaLinear10PercentEvery10Minutes
Why it's wrong here
This shifts 10% every 10 minutes, not canary.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing canary deployments (initial small traffic shift followed by a single full shift after a wait) with linear deployments (equal increments at regular intervals), leading candidates to incorrectly choose Option D.
Detailed technical explanation
How to think about this question
AWS CodeDeploy uses a traffic shifting configuration defined in the deployment group. For Lambda canary deployments, the 'Canary' prefix indicates an initial percentage of traffic is sent to the new version, and after a specified interval, the remaining traffic is shifted automatically. The '5Minutes' suffix in the correct option means the interval before the full shift is 5 minutes, allowing for monitoring and rollback if needed. In contrast, linear deployments shift traffic in equal increments at regular intervals, which is more suitable for gradual, step-by-step rollouts rather than the described canary pattern.
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.
