- A
Replicate the Cloud Storage bucket to an Asia region and update DNS to route Asian users to the regional bucket.
Why wrong: Multi-region or dual-region Cloud Storage with geo-routing is operationally complex. Cloud CDN achieves the same performance benefit with simpler configuration — just enable CDN on the Cloud Storage backend.
- B
Enable Cloud CDN on the Cloud Storage bucket's load balancer backend.
Cloud CDN caches static assets at Google's global edge PoPs. Asian users receive cached content from a nearby PoP, reducing round-trip latency to us-central1 dramatically.
- C
Deploy Cloud Run instances in Asia regions to serve the static assets.
Why wrong: Serving static assets from Cloud Run is expensive (compute cost for every static asset request) and unnecessarily complex when Cloud Storage + CDN is purpose-built for this.
- D
Increase the Cloud Storage bucket's replication factor to improve throughput.
Why wrong: Cloud Storage does not have a configurable 'replication factor' in the traditional sense. Replication is automatic within the configured storage class region.
Google ACE Your web application serves users globally Practice Question
This ACE practice question tests your understanding of your web application serves users globally. 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 web application serves users globally. Static assets (images, JS, CSS) are stored in Cloud Storage. Users in Asia report slow load times for these assets. The application origin is in `us-central1`. What is the most cost-effective way to improve static asset performance for Asian users?
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
Enable Cloud CDN on the Cloud Storage bucket's load balancer backend.
Cloud CDN uses Google's global edge cache network to serve static assets from locations close to users, reducing latency for Asian users without requiring bucket replication or additional compute. It is the most cost-effective solution because it leverages existing Cloud Storage as the origin and only charges for cache egress and operations, avoiding the overhead of managing regional buckets or compute instances.
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 misconception that moving data closer to users requires replicating the storage or deploying compute in multiple regions, when in fact a global CDN is the simplest and most cost-effective solution for static content delivery.
Detailed technical explanation
How to think about this question
Cloud CDN integrates with external HTTP(S) load balancers and caches content at Google's 100+ edge points of presence (PoPs) worldwide. When a user in Asia requests a static asset, the edge cache serves it if cached, or fetches from the origin (us-central1) and caches it for subsequent requests. Cache hit ratios can exceed 90% for static assets, and the TTL is controlled via Cache-Control headers, allowing fine-grained control over freshness.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
