This ACE practice question tests your understanding of your application exposes a rest api that external…. 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.
Your application exposes a REST API that external partners consume. You need rate limiting per partner (API key), usage analytics, and developer portal for onboarding. Traffic is currently 1,000 requests/day but expected to grow to 10M/day within a year. Which GCP service best fits these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Cloud Endpoints with Extensible Service Proxy
Cloud Endpoints provides API key management and rate limiting but does not include a developer portal — a stated requirement. Apigee is more complete for partner onboarding.
B
Distractor review
Cloud Armor with rate limiting rules
Cloud Armor provides DDoS protection and WAF rate limiting, but not API key management, usage analytics, or developer portals.
C
Best answer
Apigee API Management
Apigee provides all required features: per-key rate limiting, built-in developer portal for partner onboarding, detailed API analytics, and scales to billions of requests.
D
Distractor review
API Gateway with a backend Cloud Run service
API Gateway provides lightweight API management (OpenAPI-based routing, auth) but does not include a developer portal or the enterprise analytics required.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Apigee API Management — Apigee is Google Cloud's full-featured API management platform supporting rate limiting per API key, developer portals, analytics dashboards, and massive scale. Cloud Endpoints is a lighter-weight API management solution based on Extensible Service Proxy (ESP) that also provides rate limiting and API key management but lacks a developer portal. For enterprise-grade API management with developer portals and deep analytics, Apigee is the correct choice.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
