SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 has an Amazon RDS for PostgreSQL database that is experiencing high CPU utilization due to a large number of read queries. They need to offload read traffic and improve performance. Which TWO actions should they take? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create one or more read replicas in the same Region.
Options A and D are correct. A: Creating a read replica offloads read queries from the primary database. D: Using an RDS Proxy allows connection pooling, reducing overhead. Option B is wrong because Multi-AZ is for high availability, not read scaling. Option C is wrong because increasing instance size can help but is often more expensive than read replicas. Option E is wrong because ElastiCache is for caching data, not for offloading database queries directly.
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.
✗
Enable Multi-AZ deployment for the database.
Why it's wrong here
Multi-AZ provides failover, not read scaling.
✓
Create one or more read replicas in the same Region.
Why this is correct
Read replicas serve read traffic, reducing load on the primary.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the instance size of the primary database.
Why it's wrong here
Scaling up is less cost-effective than using read replicas.
✗
Use Amazon ElastiCache to cache query results.
Why it's wrong here
ElastiCache caches data but is not a direct offload for database queries.
✓
Implement an RDS Proxy to manage connections.
Why this is correct
RDS Proxy reduces CPU overhead from connection management.

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.
