- A
Rate limiting
Rate limiting controls the number of requests per time window from a client.
- B
TLS enforcement
Why wrong: TLS provides encryption, not request rate control.
- C
Web Application Firewall (WAF) integration
Why wrong: WAF protects against web exploits, not rate-based abuse.
- D
API key authentication
Why wrong: API keys identify clients but do not limit request rates.

CCSP Practice Question: A security analyst is configuring an API Gateway…
This CCSP practice question tests your understanding of ccsp exam topics. 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 security analyst is configuring an API Gateway for a cloud application. The application must handle high traffic and prevent abuse from a single client. Which feature should the analyst enable to limit the number of requests from a client within a specified time window?

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
✓
Rate limiting
Rate limiting throttles requests from a client to prevent abuse and ensure fair usage. API keys authenticate but do not limit rate; WAF filters malicious traffic; TLS enforces encryption.
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
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
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
