Quick Answer
The answer is the rolling update deployment type. This is correct because an ECS rolling update deployment gradually replaces running tasks with new versions, one or a few at a time, based on the configured minimum and maximum healthy percentages, ensuring continuous service availability during the update. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this concept tests your understanding of deployment strategies for containerized applications, where the key trap is confusing rolling updates with blue/green deployments—blue/green shifts all traffic at once after a full environment swap, not gradually. A common memory tip is to think of a “rolling” wave: tasks are replaced in a rolling, incremental fashion, not all at once. For the exam, remember that if the question emphasizes “gradual task replacement” without mentioning traffic shifting or environment swapping, the answer is always rolling update.
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is using AWS CodeDeploy to deploy a new version of an application to an Amazon ECS service. The deployment must be gradual to minimize impact. Which deployment type should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Linear deployment
Why wrong: Linear deployment is for Lambda, not ECS.
Rolling update deployment
Rolling update gradually replaces tasks with new versions, minimizing impact.
Canary deployment
Why wrong: Canary deployment is used for Lambda functions, not ECS.
Blue/green deployment
Why wrong: Blue/green is a different strategy that replaces all tasks at once after traffic is shifted.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Rolling update deployment
Option B is correct because ECS supports rolling update deployment, which gradually replaces tasks. Option A is wrong because blue/green is also supported but is not gradual in the same sense (it shifts all traffic at once after testing). Option C is wrong because canary is for Lambda. Option D is wrong because linear is for CodeDeploy Lambda deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Linear deployment
Why it's wrong here
Linear deployment is for Lambda, not ECS.
Rolling update deployment
Why this is correct
Rolling update gradually replaces tasks with new versions, minimizing impact.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

Blue/green deployment
Why it's wrong here
Blue/green is a different strategy that replaces all tasks at once after traffic is shifted.
Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
