- A
Cloud Endpoints with Extensible Service Proxy
Why wrong: 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
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.
- C
Cloud Armor with rate limiting rules
Why wrong: Cloud Armor provides DDoS protection and WAF rate limiting, but not API key management, usage analytics, or developer portals.
- D
API Gateway with a backend Cloud Run service
Why wrong: API Gateway provides lightweight API management (OpenAPI-based routing, auth) but does not include a developer portal or the enterprise analytics required.
Quick Answer
The answer is Apigee API Management because it is the only GCP service that natively combines API management with rate limiting per API key, usage analytics, and a developer portal for partner onboarding. Apigee enforces rate limits through configurable quota policies tied to individual API keys, while its analytics dashboards track request patterns and error rates, and the developer portal allows partners to self-register, generate keys, and view documentation. On the Google Associate Cloud Engineer exam, this question tests your ability to distinguish between lightweight API gateways like Cloud Endpoints and full-lifecycle API management platforms; a common trap is choosing Cloud Endpoints for its simplicity, but it lacks a built-in developer portal and enterprise-grade rate limiting. Remember the mnemonic “Apigee Does Portals, Quotas, and Analytics” to recall that Apigee handles the three key requirements of developer onboarding, per-key rate limiting, and usage analytics at scale.
Google ACE Planning and configuring a cloud solution Practice Question
This ACE practice question tests your understanding of planning and configuring a cloud solution. 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?

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
Apigee API Management
Apigee API Management is correct because it provides built-in rate limiting per API key (via quota policies), detailed analytics dashboards for usage tracking, and a developer portal for partner onboarding and key management. Unlike simpler API gateways, Apigee is designed for enterprise-grade API management at scale, handling growth from 1,000 to 10M requests/day with features like monetization, traffic management, and security policies.
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
Google Cloud often tests the distinction between a simple API gateway (like Cloud Endpoints or API Gateway) and a full API management platform (Apigee), where the presence of a developer portal and per-partner analytics is the key differentiator, not just rate limiting or traffic growth.
Detailed technical explanation
How to think about this question
Apigee uses a distributed architecture with a message processor layer that evaluates quota policies (e.g., using a distributed counter backed by Cassandra) to enforce rate limits per API key, even across multiple regions. The developer portal is a customizable Drupal-based site that automates API key generation and documentation publishing, while analytics are powered by Apigee's analytics pipeline that ingests request logs into a time-series database for real-time dashboards. A subtle behavior: Apigee's quota can be configured with 'time unit' (e.g., per minute) and 'distributed' mode to handle high concurrency without race conditions, which is critical for scaling to 10M requests/day.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
