Google PCA Manage implementation of cloud architecture Practice Question
A media streaming company uses Google Cloud CDN to deliver content. They notice that users in certain regions experience high latency despite CDN caching. The content is dynamic based on user location (e.g., local news). What should they do to improve performance?
⚠ Common exam trap
Google Cloud often tests the misconception that Cloud CDN alone can solve latency for dynamic content, but the trap here is that dynamic, location-specific content cannot be effectively cached, so the correct solution is to deploy compute resources closer to users and use a global load balancer for intelligent routing.

Correct answer & explanation
✓
Deploy Cloud Run services in multiple regions and use a global external HTTPS load balancer with backend services to route requests to the nearest region
Deploying Cloud Run services in multiple regions and using a global external HTTPS load balancer with backend services enables location-based routing via the load balancer's anycast IP and backend service configuration. The load balancer automatically routes user requests to the nearest Cloud Run backend that has capacity, reducing latency for dynamic, location-specific content that cannot be effectively cached by Cloud CDN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Deploy Cloud Run services in multiple regions and use a global external HTTPS load balancer with backend services to route requests to the nearest region
Why this is correct
This reduces latency for dynamic content by serving from the nearest region.
- ✗
Use Cloud Functions with a regional HTTP trigger and Cloud CDN to cache the responses
Why it's wrong here
Cloud Functions are regional; Cloud CDN caching dynamic content may serve stale data.
- ✗
Use Cloud Armor to route traffic to the nearest point of presence
Why it's wrong here
Cloud Armor is a WAF/DDoS protection service, not a routing solution.
- ✗
Configure Cloud CDN to use cache keys based on user location headers
Why it's wrong here
Cloud CDN does not support user-location-based cache keys; dynamic content shouldn't be cached.
