This SAA-C03 practice question tests your understanding of design high-performing architectures. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: rDS Proxy pools and reuses database connections.. 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 video platform uses Amazon Aurora. The workload has many short-lived database connections from Lambda functions, causing connection storms. What should be added? The design must avoid adding custom operational scripts.
S3 Select
Why wrong: S3 Select queries object content and is unrelated to database connection pooling.
An internet gateway
Why wrong: An internet gateway does not manage database connections.
A larger Route 53 hosted zone
Why wrong: DNS hosted zones do not solve connection storms.
RDS Proxy
RDS Proxy pools and manages database connections, improving scalability for serverless and bursty workloads.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
RDS Proxy
RDS Proxy is the correct choice because it sits between Lambda functions and the Aurora database, pooling and reusing database connections. This prevents connection storms by reducing the overhead of establishing new connections for each short-lived Lambda invocation, without requiring custom scripts or application changes.
Key principle: RDS Proxy pools and reuses database connections.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
S3 Select
Why it's wrong here
S3 Select queries object content and is unrelated to database connection pooling.
An internet gateway
Why it's wrong here
An internet gateway does not manage database connections.
A larger Route 53 hosted zone
Why it's wrong here
DNS hosted zones do not solve connection storms.
RDS Proxy
Why this is correct
RDS Proxy pools and manages database connections, improving scalability for serverless and bursty workloads.
Related concept
RDS Proxy pools and reuses database connections.
Common exam traps
The trap here is that candidates may think scaling the database (e.g., using Aurora Auto Scaling) or adding more compute resources solves connection storms, but the real bottleneck is the connection overhead itself, which RDS Proxy directly addresses without custom scripts.
Detailed technical explanation
RDS Proxy maintains a warm pool of connections to the Aurora database and multiplexes them across multiple Lambda invocations, significantly reducing the number of new connections and the associated memory and CPU overhead. It also supports IAM authentication and can enforce connection limits, making it ideal for serverless architectures where Lambda functions create frequent, short-lived connections. Under the hood, RDS Proxy uses a transaction-level multiplexing model that can handle up to thousands of concurrent connections from Lambda while keeping the actual database connections minimal.
Key takeaway
RDS Proxy pools and reuses database connections.
Real-world example
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.
