What is the primary reason to use a Secret instead of a ConfigMap for storing sensitive data like database passwords?

Secrets are encrypted at rest by default in all Kubernetes clusters

Secrets are automatically rotated by Kubernetes

Secrets are stored in a separate, more secure database

Secrets are designed to hold sensitive data and have additional access controls and best practices

A DevOps engineer notices that a newly deployed pod is stuck in the 'ContainerCreating' state. The engineer runs 'kubectl describe pod' and sees an event indicating that the container runtime could not pull the image. Which component should the engineer investigate first to resolve this issue?

The API server, which validates and stores the pod definition

The scheduler, which assigned the pod to the node

The kubelet on the worker node where the pod is scheduled

The controller manager, which reconciles the desired state
