Why is container orchestration needed?

To provide a graphical interface for individual containers.

To manage containerized applications at scale.

To store container images in a centralized registry.

To build container images from source code.

A containerized application needs to store user-uploaded files. The files must persist across container restarts and be accessible from multiple replicas. Which storage solution should be used?

Ephemeral storage in each container

A persistent volume backed by a shared file system

A developer creates a Dockerfile that installs dependencies, copies application code, and sets the entrypoint. What is the result of running the build command?

A container runtime configuration

A Kubernetes cluster has multiple microservices that need to communicate with each other. Some services are internal and should not be exposed to the internet. What is the best way to enable service-to-service communication while keeping internal services private?

Use a container registry for service discovery

Expose all services via NodePort

Use ClusterIP services for internal communication and expose only the frontend via a LoadBalancer

Place all services in a single pod

What is a key difference in startup time between containers and virtual machines?

VMs start faster because they use hardware virtualization.

Containers start faster because they do not boot a guest OS.

Containers and VMs have similar startup times.

VMs start faster because they do not include an OS.
