KCNA Container Orchestration Practice Question
Which THREE of the following are correct statements about Kubernetes Deployments?
⚠ Common exam trap
The KCNA exam often tests the misconception that Deployments directly manage Pods, when in fact they manage ReplicaSets, and that canary deployments are a built-in feature of Deployments, whereas they require external traffic management.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A Deployment manages ReplicaSets
A Deployment manages ReplicaSets, which in turn manage Pods. This is the core abstraction: the Deployment controller creates and updates ReplicaSets to achieve the desired state, and each ReplicaSet ensures a specified number of Pod replicas are running. This layered architecture enables features like rolling updates and rollbacks without the Deployment directly interacting with individual Pods.
