CV0-004 Practice Question: Needs to deploy a stateless application across…
A cloud engineer needs to deploy a stateless application across multiple availability zones. The application must scale horizontally based on CPU utilization. Which of the following is the BEST configuration?
⚠ Common exam trap
A common trap is choosing vertical scaling (Option A) because it seems simpler, but it does not meet the requirement for multi-AZ distribution and automated horizontal 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
✓
Create an auto-scaling group spanning multiple zones with a load balancer
An auto-scaling group spanning multiple availability zones ensures high availability and fault tolerance by distributing instances across zones, while the load balancer distributes traffic and the scaling policy adjusts capacity based on CPU utilization. This configuration meets the requirements for a stateless, horizontally scalable application without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a single large instance and increase its size as needed
Why it's wrong here
Vertical scaling is not horizontal, and a single instance is a single point of failure.
- ✓
Create an auto-scaling group spanning multiple zones with a load balancer
Why this is correct
This provides automated horizontal scaling and fault tolerance.
- ✗
Use a managed container service and manually add containers
Why it's wrong here
Manual scaling does not meet the requirement for automated scaling.
- ✗
Deploy instances in one zone using spot instances to reduce cost
Why it's wrong here
Spot instances are not reliable for stateless applications needing consistent scaling.
