Kubernetes and Cloud Native Associate (KCNA) — Question 177

In the Kubernetes platform, which component is responsible for running containers?

Answer options

• A. etcd
• B. CRI-O
• C. cloud-controller-manager
• D. kube-controller-manager

Correct answer: B

Explanation

The correct answer is B, CRI-O, which is specifically designed for managing the lifecycle of containers in Kubernetes. The other options, such as etcd, function as a key-value store for cluster data, while cloud-controller-manager and kube-controller-manager serve different roles related to cluster management and resource control, not directly running containers.
