CV0-004 Deployment Practice Question
A cloud engineer is tasked with deploying a containerized application on Kubernetes. The application must handle varying loads, and the deployment should automatically replace failed containers. Which Kubernetes object should the engineer use to achieve self-healing and scalability?
⚠ Common exam trap
CompTIA Cloud+ often tests the misconception that a Pod alone provides self-healing, but in Kubernetes, a Pod is a non-self-healing atomic unit; only controllers like Deployment (or StatefulSet/DaemonSet) provide automatic replacement and scaling.
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 Deployment is the correct Kubernetes object because it manages ReplicaSets to provide declarative updates, self-healing (automatic replacement of failed pods), and scalability (adjusting replica counts). Unlike a standalone Pod, a Deployment ensures the desired state is maintained, automatically rescheduling containers if they fail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ConfigMap
Why it's wrong here
ConfigMaps store configuration data, not application lifecycle.
- ✗
Service
Why it's wrong here
Services provide network access to Pods but do not manage Pod lifecycle.
- ✓
Deployment
Why this is correct
A Deployment ensures desired number of Pods are running and supports rolling updates.
- ✗
Pod
Why it's wrong here
Pods are the smallest deployable units but do not provide self-healing or scaling on their own.
