- A
Built-in caching of database queries to Amazon RDS
Why wrong: API Gateway can cache responses, but not specifically RDS queries.
- B
Direct integration with Amazon S3 for file storage
Why wrong: API Gateway can proxy to S3 but does not provide direct file storage.
- C
Throttling and rate limiting of API requests
API Gateway supports throttling at the API level.
- D
Generation of client SDKs for multiple programming languages
API Gateway can generate SDKs from the API definition.
- E
Automatic connection pooling for backend databases
Why wrong: Connection pooling is not a feature of API Gateway.
Question 1,337 of 1,616
Top Benefits of Amazon API Gateway: Throttling, SDK Generation, and More
This DVA-C02 practice question tests your understanding of development with aws services. 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.
Which TWO of the following are benefits of using Amazon API Gateway to manage APIs? (Choose two.)
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
✓
Throttling and rate limiting of API requests
Option C is correct because Amazon API Gateway provides built-in throttling and rate limiting at the API level, allowing you to set a steady-state request rate and a burst limit per method or per API key. This protects backend systems from traffic spikes and ensures fair usage across consumers. The throttling is enforced using a token bucket algorithm, with default limits of 10,000 requests per second (rps) and a burst of 5,000 requests per region.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse API Gateway's integration capabilities (e.g., proxying to S3 or RDS) with built-in backend features like caching or connection pooling, leading them to select options that describe backend functionality rather than API management features.
Detailed technical explanation
How to think about this question
API Gateway's throttling uses a token bucket algorithm where each API key or account has a configurable rate limit and burst capacity; exceeding the burst results in a 429 Too Many Requests response. The generated SDKs (Option D) are based on the API's OpenAPI/Swagger definition and support languages like Java, JavaScript, Python, and Ruby, enabling client developers to quickly integrate without manually crafting HTTP calls. In real-world scenarios, combining throttling with usage plans and API keys allows you to monetize APIs or enforce tiered access for different customers.
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.
TExam Day Tips
- 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.
