The answer is to use Amazon RDS Proxy for connection pooling and auto scaling. This is correct because RDS Proxy sits between your application and the database, maintaining a pool of established connections that can be reused across many application instances, which prevents the database from being overwhelmed by a surge of open connections. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of how to decouple application scaling from database connection limits—a common trap is thinking that scaling EC2 instances or the database instance type alone solves the problem, but those actions don’t address the connection overhead. RDS Proxy automatically scales its connection pool as application demand fluctuates, making it ideal for Elastic Beanstalk environments where traffic spikes can degrade performance. Memory tip: think of RDS Proxy as a “bouncer” for your database—it controls who gets in and how many, so your DB never gets trampled by a crowd of connections.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is using AWS Elastic Beanstalk to deploy a web application. The application's performance degrades over time due to increasing database connections. The company wants to implement a solution that automatically scales the database tier based on connection count. Which action should be taken?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon RDS Proxy to manage database connections and enable connection pooling.
Option B is correct because Amazon RDS Proxy manages connection pooling and can scale with application, reducing load on database. Option A is wrong because DynamoDB is a different database. Option C is wrong because scaling EC2 instances does not address database connections. Option D is wrong because modifying RDS instance type is manual and not automatic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Migrate the database to Amazon DynamoDB with auto scaling.
Why it's wrong here
Not a direct replacement for relational database.
✓
Use Amazon RDS Proxy to manage database connections and enable connection pooling.
Why this is correct
RDS Proxy reduces connection overhead and scales.

✗
Enable Multi-AZ on the RDS instance and modify the DB instance class.
Why it's wrong here
Manual, not automatic scaling.
✗
Configure the Auto Scaling group to scale based on CPU utilization.
Why it's wrong here
Does not address database connection issue.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
