DBS-C01 Management and Operations Practice Question
Which TWO of the following are benefits of using Amazon RDS Proxy? (Choose TWO.)
⚠ Common exam trap
Watch out — candidates often confuse RDS Proxy's connection pooling with other features like encryption, read/write splitting, or compression, which are separate capabilities not provided by the proxy itself.
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
✓
Reduces the number of database connections by pooling them.
Amazon RDS Proxy acts as a connection broker between your application and the database, maintaining a pool of established connections. When the application opens a new connection, RDS Proxy reuses an idle connection from the pool, which reduces the total number of database connections and prevents the database from being overwhelmed. This pooling mechanism directly addresses the issue of connection exhaustion, especially in serverless or highly concurrent environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Reduces the number of database connections by pooling them.
Why this is correct
Connection pooling reduces the number of open connections.
- ✗
Automatically encrypts all traffic between the application and the database.
Why it's wrong here
RDS Proxy supports TLS but does not automatically encrypt; encryption is configured separately.
- ✓
Improves application scalability by handling connection surges.
Why this is correct
RDS Proxy allows the application to scale without exhausting database connections.
- ✗
Provides built-in read/write splitting for read replicas.
Why it's wrong here
Read/write splitting is not a feature of RDS Proxy; it requires application logic.
- ✗
Reduces storage costs by compressing data in transit.
Why it's wrong here
RDS Proxy does not compress data.
