The term 'pod' in Kubernetes refers to what?

A group of nodes
A single container
A group of one or more containers
A collection of services

The correct answer is: A group of one or more containers

In Kubernetes, a 'pod' is the smallest deployable unit and represents a group of one or more closely related containers that share the same network namespace and storage volumes. This grouping allows the containers to work together and communicate efficiently as they share an IP address and port space, making inter-container communication straightforward. Pods are designed to host applications that require multiple components to function cohesively, like a web server and a database that need to interact with one another. By allowing multiple containers to run in a single pod, Kubernetes optimizes resource usage and simplifies orchestration by managing these containers as a single unit. This design supports scenarios where containers have related functionalities, enhancing the application's performance and management.
