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) automatically scales the number of pods based on metrics like CPU utilization or custom metrics, enabling dynamic scaling in a microservices architecture. Option A is incorrect because manually adding VMs is not dynamic and requires human intervention. Option B is incorrect because a monolithic application on a single instance cannot scale dynamically and lacks microservices benefits. Option D is incorrect because a single large instance with a load balancer still has a fixed capacity and cannot scale out automatically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually add more virtual machines during peak hours
Why it's wrong here
Manual scaling is slow and error-prone.
- ✗
Deploy a monolithic application on a single large instance
Why it's wrong here
Monolithic architectures are difficult to scale efficiently.
- ✓
Kubernetes with Horizontal Pod Autoscaler
Why this is correct
Kubernetes automates container orchestration and HPA scales pods based on demand.
- ✗
Use a single large instance with a load balancer
Why it's wrong here
A single instance creates a single point of failure and does not scale out.
