The correct answer is to enable enhanced health reporting and enable AWS X-Ray integration for tracing. Enhanced health reporting provides detailed, real-time environment health metrics that go beyond basic status checks, allowing you to pinpoint resource saturation or configuration issues causing high latency. X-Ray complements this by offering end-to-end request tracing, which helps identify specific bottlenecks in your application code or downstream services. On the AWS Certified Developer Associate DVA-C02 exam, this scenario tests your understanding of Elastic Beanstalk’s built-in observability tools versus reactive scaling or infrastructure changes—a common trap is jumping to increase instance size or change regions, which are optimization steps, not troubleshooting steps. Remember the memory tip: “Health to see the problem, X-Ray to find the cause.”
DVA-C02 Troubleshooting and Optimization Practice Question
This DVA-C02 practice question tests your understanding of troubleshooting and optimization. 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 developer is using AWS Elastic Beanstalk to deploy a web application. The application is experiencing high latency. Which TWO steps should the developer take to troubleshoot and optimize the application?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable AWS X-Ray integration and analyze service maps.
Option B is correct because enabling enhanced health reporting provides detailed metrics. Option D is correct because enabling X-Ray integration provides tracing to identify bottlenecks. Option A is wrong because deploying to a different region might not help latency for existing users. Option C is wrong because increasing instance size could help but not a troubleshooting step. Option E is wrong because RDS is not involved.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Increase the instance type to a larger size.
Why it's wrong here
Optimization step, not troubleshooting.
✗
Deploy the application to a different AWS region.
Why it's wrong here
Does not troubleshoot latency; might increase latency for current users.
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
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. A company runs a Node.js application on AWS Elastic Beanstalk. The application is experiencing high latency. The developer suspects the database queries are slow. Which step should the developer take first to diagnose the issue?
medium
A.Migrate the database to Amazon DynamoDB for better performance.
✓ B.Enable enhanced health reporting and monitor CloudWatch metrics for database connection time.
C.Add database indexing to improve query performance.
D.Increase the instance size to improve performance.
Why B: The first step is to enable enhanced health reporting and use CloudWatch metrics to monitor database query performance. Option B is wrong because increasing instance size is a solution, not diagnosis. Option C is wrong because you need to identify the slow queries first. Option D is wrong because switching to DynamoDB is a major architectural change.
