This DVA-C02 practice question tests your understanding of deployment. 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 developer is using AWS CodeDeploy to deploy a new version of an AWS Lambda function. The developer wants to gradually shift traffic from the old version to the new version in 10-minute increments. Which deployment configuration should the developer use?
Why wrong: This configuration shifts 10% of traffic initially, then after 10 minutes, it shifts the remaining 90% all at once. This is not an incremental shift.
B
Canary10Percent30Minutes
Why wrong: Similar to Canary10Percent10Minutes but with a longer initial 30-minute wait before shifting the rest. It still does not shift in 10-minute increments.
C
Linear10PercentEvery10Minutes
This configuration shifts 10% of traffic every 10 minutes until 100% is shifted, meeting the requirement of gradual 10-minute increments.
D
AllAtOnce
Why wrong: This configuration immediately shifts all traffic to the new version, causing a full cutover rather than a gradual shift.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Linear10PercentEvery10Minutes
The Linear10PercentEvery10Minutes configuration shifts traffic from the old Lambda version to the new version in 10% increments every 10 minutes, which matches the developer's requirement of gradually shifting traffic in 10-minute increments. This is a linear deployment type in AWS CodeDeploy that provides a steady, incremental traffic shift over time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Canary10Percent10Minutes
Why it's wrong here
This configuration shifts 10% of traffic initially, then after 10 minutes, it shifts the remaining 90% all at once. This is not an incremental shift.

Why it's wrong here
Similar to Canary10Percent10Minutes but with a longer initial 30-minute wait before shifting the rest. It still does not shift in 10-minute increments.
✓
Linear10PercentEvery10Minutes
Why this is correct
This configuration shifts 10% of traffic every 10 minutes until 100% is shifted, meeting the requirement of gradual 10-minute increments.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing canary deployments (which shift a small percentage immediately and then the remainder after a wait) with linear deployments (which shift traffic in equal increments over time), leading candidates to select a canary configuration when a linear one is required.

Detailed technical explanation
How to think about this question
AWS CodeDeploy supports three deployment types for Lambda: Canary, Linear, and AllAtOnce. Linear deployments shift traffic in equal percentage increments at specified time intervals, allowing for fine-grained control over traffic shifting. The Linear10PercentEvery10Minutes configuration is ideal for production deployments where you want to monitor error rates and performance metrics at each 10% step before proceeding to the next increment.

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.
