CV0-004 Practice Question: A cloud architect must design a deployment for a…
A cloud architect must design a deployment for a containerized microservices application. The requirements include automated scaling based on CPU utilization, rolling updates with zero downtime, and service discovery. Which orchestration feature should be used?
⚠ Common exam trap
Many exam-takers confuse a container runtime or provisioning tool (like Docker Compose or Ansible) with a full orchestration platform, or assume that a managed service like ECS is an orchestration feature rather than a cloud implementation, missing that Kubernetes is the specific feature set that directly satisfies all three requirements.
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
✓
Kubernetes with Horizontal Pod Autoscaler
Kubernetes with Horizontal Pod Autoscaler (HPA) is the correct choice because HPA automatically scales the number of pod replicas based on observed CPU utilization (or custom metrics), meeting the automated scaling requirement. Kubernetes also supports rolling updates with zero downtime via its Deployment controller, which gradually replaces old pods with new ones while maintaining service availability. Additionally, Kubernetes provides built-in service discovery through DNS (CoreDNS) and Services, allowing microservices to find each other by name without external dependencies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Docker Compose with a reverse proxy
Why it's wrong here
Docker Compose is for single-host orchestration, lacks autoscaling.
- ✓
Kubernetes with Horizontal Pod Autoscaler
Why this is correct
Kubernetes natively supports autoscaling, rolling updates, and service discovery.
- ✗
Ansible playbooks with Docker modules
Why it's wrong here
Ansible is for configuration management, not real-time orchestration.
- ✗
AWS ECS with Fargate
Why it's wrong here
ECS with Fargate supports autoscaling but service discovery requires extra setup.
