SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
Network Topology
A company is migrating a web application to AWS. The application runs on EC2 instances behind an Application Load Balancer. The exhibit shows the current running instances. The company wants to ensure high availability across multiple Availability Zones. Which action should the company take?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change the m5.xlarge instance in us-east-1c to an m5.large in us-east-1c or move it to another AZ.
The current instance distribution shows an m5.large in us-east-1b (or similar) and an m5.xlarge in us-east-1c, which is inconsistent. To ensure high availability across multiple Availability Zones, the company should either change the m5.xlarge to an m5.large to match instance types, or move it to a different AZ to better distribute instances. This avoids a single point of failure and ensures balanced capacity. Option A is incorrect because adding more instances to us-east-1a does not improve AZ diversity. Option C is incorrect because terminating the m5.xlarge and launching an m5.large in the same AZ does not change the AZ distribution. Option D is incorrect because placing all instances in a single AZ eliminates high availability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Launch additional m5.large instances in us-east-1a.
Why it's wrong here
This concentrates instances in one AZ, reducing HA.
- ✓
Change the m5.xlarge instance in us-east-1c to an m5.large in us-east-1c or move it to another AZ.
Why this is correct
Balancing instance types and ensuring even distribution across AZs improves HA.
- ✗
Terminate the m5.xlarge instance in us-east-1c and launch an m5.large in the same AZ.
Why it's wrong here
Terminating reduces capacity; the instance type difference is not a HA issue.
- ✗
Place all instances in a single AZ and use an Auto Scaling group.
Why it's wrong here
Single AZ is not highly available.
