A team wants every push to the main branch to compile the application, run the test suite, and — only if the tests pass — deploy to a staging environment, with the whole sequence visible and repeatable rather than living in someone's shell history. Which service models that sequence?
AWS Certified Cloud Practitioner (CLF-C02), objective 3. Cloud technology and services medium
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
The options
Correct AWS CodePipeline
Correct. CodePipeline is the continuous delivery service: it models the stages, their order and the condition that one must succeed before the next runs, and it shows where a given change has reached.
Not correct AWS CodeBuild on its own
Wrong, because it is one stage of the sequence. CodeBuild compiles and tests and produces an artifact; it does not express 'and then deploy, if that passed'.
Not correct AWS CodeDeploy on its own
Wrong, and it is the other single stage. CodeDeploy takes an artifact that already exists and installs it onto instances, Lambda or ECS, with rollback. It neither builds nor orchestrates.
Not correct AWS CloudFormation
Wrong. CloudFormation provisions infrastructure from a template, and it is very often a step INSIDE such a pipeline. It is not the thing that decides which step runs next.
Why
Learn the developer tools by their verb. CodePipeline decides the order. CodeBuild makes the artifact. CodeDeploy puts it where it goes. The source repository is either AWS CodeCommit or a third-party service the pipeline connects to. Around them sit AWS Cloud9 as a browser IDE, AWS X-Ray for tracing a request across services, and AWS Amplify for building and hosting web and mobile front ends.

More questions on this objective
- A team builds the same stack — a load balancer, three EC2 instances and a database — by clicking through the console once for dev, once for test and once for production. The three environments have quietly drifted apart and a bug that only appears in production took a week to trace to a missing setting. They want the stack described once, reviewed in a pull request, and applied identically to each environment. Which service does that? machine-checked
- A Python reporting job runs unattended every night. Inside its own logic it needs to list objects in an S3 bucket, read a few of them, and write a summary object back, handling failures with the program's existing retry and logging code. What is the appropriate way for that program to call AWS? machine-checked
- A small team has a Java web application and no operations staff. They want to hand AWS the application package and have it provision the instances, the load balancer and the scaling policy, while keeping the ability to inspect and adjust those resources later if they need to. Which service fits? machine-checked
- A manufacturer keeps its plant-floor control application on servers inside the factory, because production must continue when the internet link drops. Its reporting and analytics run in AWS and read the same production data. Which TWO statements about this arrangement are accurate? machine-checked
- An internal application runs on a single EC2 instance in one Availability Zone. During a power event in that Availability Zone the application was unreachable for four hours. The team wants the cheapest change that keeps it serving through the same kind of event, without moving to another Region. What should they do? machine-checked
- A German insurer is told by its regulator that customer records must remain within the European Union. Four candidate Regions can all run every service the workload needs, and one of them is noticeably cheaper per instance-hour. Which consideration settles the choice of Region first? machine-checked
