CV0-004 Deployment Practice Question
A cloud administrator needs to deploy a new version of an application to a Kubernetes cluster. The administrator wants to update the application without downtime and ensure that if the new version fails, the deployment automatically rolls back to the previous version. Which Kubernetes resource should the administrator use?
⚠ Common exam trap
The trap here is assuming that any workload controller can handle rolling updates and rollbacks, but only Deployments are specifically designed for stateless application version management with automatic rollback.
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
✓
Deployment
A Kubernetes Deployment is the correct resource because it provides declarative updates for pods and ReplicaSets, enabling rolling updates and automatic rollbacks. It ensures that the application remains available during updates and reverts to the previous version if the new version fails. Other resources are designed for different use cases and do not offer these capabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deployment
Why this is correct
A Kubernetes Deployment manages the rollout of new versions by creating a ReplicaSet and gradually replacing pods. It supports rolling updates and automatic rollback if the new version fails health checks, ensuring zero downtime and safe deployment, which matches the administrator's requirements.
- ✗
StatefulSet
Why it's wrong here
StatefulSet is designed for stateful applications that require stable network identities and persistent storage. It does not provide automatic rollback on failure by default and is not optimized for stateless application updates, making it unsuitable for this scenario.
- ✗
DaemonSet
Why it's wrong here
DaemonSet ensures that a copy of a pod runs on all or some nodes, typically for system daemons like log collectors. It is not used for deploying application versions with rolling updates and rollback capabilities, so it does not meet the requirement.
- ✗
Job
Why it's wrong here
A Job runs a pod to completion for batch tasks. It does not manage long-running applications, nor does it support rolling updates or rollbacks. Using a Job for application deployment would not provide the desired zero-downtime update and automatic rollback features.
