Web Development Deployment 4

Question 1

What is the purpose of semantic versioning (SemVer) in deployments?

Accepted Answer

To communicate the nature of changes via MAJOR.MINOR.PATCH version numbers

Answer

SemVer uses MAJOR (breaking), MINOR (new features), and PATCH (bug fixes) numbers to signal change impact to consumers.

Question 2

Which deployment artifact format does AWS Lambda primarily execute?

Accepted Answer

Docker images or ZIP archives containing function code and dependencies

Answer

Lambda accepts either a ZIP package with code and dependencies or a container image stored in ECR.

Question 3

What problem does a container registry (like Docker Hub or ECR) solve?

Accepted Answer

Storing, versioning, and distributing container images to deployment targets

Answer

A container registry is a centralized store where teams push images and deployment systems pull them to run containers.

Question 4

What is a deployment pipeline's 'artifact' stage responsible for?

Accepted Answer

Packaging the built application into a deployable unit (e.g., ZIP, image, tarball)

Answer

The artifact stage compiles and packages the application so the same immutable bundle can be promoted through environments.

Question 5

Which strategy allows you to test a new feature with 10% of real users without a full deployment?

Accepted Answer

Feature flags

Answer

Feature flags let you toggle features on for a percentage of users without deploying new code for each change.
