- A
Configure the application to use the Aurora reader endpoint for read-only queries.
The reader endpoint load balances across readers, offloading reads from the writer.
- B
Upgrade the writer instance to a larger instance class to handle both read and write operations.
Why wrong: Upgrading the writer does not offload reads; it only increases capacity.
- C
Create additional reader instances to distribute the read load.
Why wrong: Adding more readers may help, but the application still needs to direct traffic to them.
- D
Implement a read-only Aurora cluster and point read queries to it.
Why wrong: Creating a separate cluster is unnecessary; the existing readers can be used.

DBS-C01 Aurora Reader Endpoint Practice Question
This DBS-C01 practice question tests your understanding of management and operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: aurora Reader Endpoint. 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 gaming company uses Amazon Aurora PostgreSQL for its leaderboard data. The database has a writer instance and two reader instances. The application frequently queries the leaderboard to display top players. The queries involve sorting and aggregation on a large table with millions of rows. Recently, the queries started timing out during peak hours. The database administrator analyzed the workload and found that the reader instances are underutilized, while the writer instance has high CPU due to write operations. The administrator wants to offload the read-heavy leaderboard queries to the readers without modifying the application code. What should the administrator do?
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
✓
Configure the application to use the Aurora reader endpoint for read-only queries.
Option A is correct because the Amazon Aurora reader endpoint automatically distributes read-only connections across all available reader instances. Since the reader instances are underutilized, using the reader endpoint offloads the read-heavy leaderboard queries from the writer instance without any application code modifications. Option B is incorrect because upgrading the writer instance does not offload read queries and does not utilize the underutilized readers. Option C is incorrect because the existing readers are underutilized; adding more readers would not solve the problem of directing queries to them. Option D is incorrect because creating a separate read-only Aurora cluster is unnecessary and more complex than using the existing reader endpoint.
