What is the primary function of Container Orchestration?

• A. Supporting the operational needs in running containers
• B. Building container images from Dockerfiles
• C. Managing host network devices
• D. Providing a user interface for containers

Answer: (B)

Container orchestration coordinates running containers across a cluster, automating deployment, scaling, updates, and health management. It schedules containers onto nodes based on resource needs, ensures the system reaches and maintains the desired state, handles rolling updates and rollbacks, and provides service discovery, networking, and storage orchestration to keep workloads responsive and resilient. Building container images from Dockerfiles is a separate task performed by image-building tools, not by orchestration. The other options describe ancillary aspects or lower-level duties, but they don’t capture the ongoing lifecycle management and scheduling focus of container orchestration.
