SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company runs a stateless web application on EC2 instances in an Auto Scaling group. The application experiences high latency during peak hours. The operations team suspects that the instances are overloaded. Which TWO actions should the team take to improve performance and scalability? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure an Application Load Balancer in front of the Auto Scaling group.
Option B is correct because adding an ALB distributes traffic across instances. Option D is correct because launching instances across multiple AZs improves availability and scalability. Option A is wrong because larger instances may not help if the issue is concurrency. Option C is wrong because increasing desired capacity without a load balancer may cause uneven distribution. Option E is wrong because changing the AMI does not directly improve performance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Increase the Auto Scaling group's desired capacity to a higher fixed value.
Why it's wrong here
Fixed capacity may not adapt to demand; without a load balancer, traffic may not be balanced.
✓
Configure an Application Load Balancer in front of the Auto Scaling group.
Why this is correct
ALB distributes traffic evenly across instances.

Read the scenario before looking for a memorised answer.
✗
Switch to a different Amazon Machine Image (AMI) with optimized performance.
Why it's wrong here
AMI change does not directly improve scalability.
✓
Launch the Auto Scaling group in multiple Availability Zones.
Why this is correct
Multi-AZ improves fault tolerance and scalability.

✗
Increase the instance size to a larger type.
Why it's wrong here
Vertical scaling may not address the root cause of overload.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
What to study next
