CKAD Practice Question: Application Environment, Configuration and Security
Which API version is correct for a Deployment in Kubernetes v1.29?
⚠ Common exam trap
Test-takers frequently confuse the core v1 API group (used for Pods) with the apps/v1 group (used for Deployments), or mistakenly think that beta versions like apps/v1beta2 are still valid in recent Kubernetes releases.

Correct answer & explanation
✓
apps/v1
(apps/v1) is correct because the Deployment API version apps/v1 has been the stable version since Kubernetes v1.9, and it is the only correct version for creating Deployments in Kubernetes v1.29. The apps/v1 API group is the current, stable, and recommended version for managing Deployments, ReplicaSets, and other workload resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
extensions/v1beta1
Why it's wrong here
The extensions/v1beta1 API group predates the dedicated apps group and held Deployment objects before apps/v1 existed. It was deprecated as part of the Kubernetes deprecation policy and was no longer served starting in version 1.16, so any manifest written against it is rejected by current clusters. The only supported, stable alternative is apps/v1.
- ✗
v1
Why it's wrong here
The bare v1 apiVersion corresponds to the core API group, which only contains fundamental cluster resources like Pods, Services, ConfigMaps, and Secrets. A Deployment is defined under the apps API group, not the core group, so apiVersion: v1 combined with kind: Deployment is invalid and the API server returns a no-match error. You must specify apps/v1 to address the correct endpoint.
- ✗
apps/v1beta2
Why it's wrong here
The apps/v1beta2 version was an intermediate beta release inside the apps group that existed while Deployment and related APIs were still maturing. After apps/v1 reached general availability, this beta version was deprecated and, like other pre-GA versions, was removed from service in Kubernetes 1.16. Using a removed version is unsupported and breaks cluster compatibility, so apps/v1 is the required choice.
- ✓
apps/v1
Why this is correct
The apps/v1 version is the stable, general-availability API for Deployment and other workload resources. It has been the standard since Kubernetes 1.9 and is fully supported by all modern clusters, containing the complete set of stable fields and behaviors. kubectl and other tooling default to this version, making it the correct and safest apiVersion for Deployment manifests.
