Welcome to your Kubernetes Best Practices Challenge

What is the principle of least privilege in Kubernetes RBAC?

Grant only the minimum permissions necessary for each role

Use default service accounts for all applications

Which practice is recommended for storing sensitive data in Kubernetes?

It helps the scheduler place pods efficiently and prevents resource starvation

It's only needed for production environments

It slows down pod creation intentionally

What's the recommended approach for CPU limits?

Always set CPU limits equal to requests

Never set CPU limits to allow bursting

Set CPU limits as low as possible

Consider not setting CPU limits to avoid throttling, but always set requests

What's a key benefit of using readiness probes?

They restart crashed containers

They prevent traffic from being sent to pods that aren't ready

They reduce image size

They speed up container startup

Which deployment strategy provides zero-downtime updates?
