City developers need to package municipal apps with their dependencies into portable images that run consistently from laptop to cloud. Which tool purpose best matches that need?
Select an answer to reveal the explanation.
Short Explanation
Shipping the app plus its libraries in one portable image is classic Docker territory. Same image on a laptop or in the cloud means fewer "works on my machine" surprises. Metrics DBs and paper runbooks do not package runtime dependencies that way.
Full Explanation
Docker packages applications and dependencies into container images that run consistently across environments, which is a foundational DevOps packaging practice. Metrics stores, inventory systems, and paper runbooks do not provide that portable runtime packaging. Cloud+ expects candidates to map container tooling to build-and-run fundamentals.
