SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a large e-commerce platform to AWS using a lift-and-shift approach. The application consists of a web tier, application tier, and a MySQL database. After migration, users report intermittent slow page loads. The operations team notices high CPU utilization on the application tier instances. Which THREE steps should the team take to address the performance issues?
⚠ Common exam trap
Many candidates confuse database-level solutions (like Multi-AZ or read replicas) with application-tier CPU issues, or they default to vertical scaling (larger instances) instead of recognizing the need for horizontal scaling and content caching.
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
✓
Implement Amazon CloudFront to cache static content and reduce load on the web tier.
Implementing Amazon CloudFront to cache static content offloads requests from the web tier, reducing the number of dynamic requests that reach the application tier. This directly lowers CPU utilization on the application instances by minimizing the processing overhead for repeated static asset deliveries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement Amazon CloudFront to cache static content and reduce load on the web tier.
Why this is correct
Reduces requests to the origin servers.
- ✓
Create an Amazon RDS read replica for the MySQL database and route read queries to it.
Why this is correct
Offloads read traffic from the primary database.
- ✗
Replace the current application tier instances with larger instance types.
Why it's wrong here
Vertical scaling is less flexible and may not be cost-effective.
- ✗
Move the MySQL database to Amazon RDS for MySQL and enable Multi-AZ deployment.
Why it's wrong here
Multi-AZ improves availability, not CPU performance on app tier.
- ✓
Configure an Auto Scaling group for the application tier to scale based on CPU utilization.
Why this is correct
Automatically adds instances during high CPU.
