- A
Move the Cloud Storage bucket to a multi-region bucket in Asia
Why wrong: Moving the bucket to Asia improves Asian users but degrades US users — multi-region improves availability, not necessarily CDN-level edge caching performance.
- B
Enable Cloud CDN on the load balancer backend pointing to the Cloud Storage bucket
Cloud CDN caches content at Google's global edge PoPs. Asian users receive cached assets from the nearest edge location, drastically reducing latency without changing the origin.
- C
Replicate the Cloud Storage bucket to multiple regions using storage transfer
Why wrong: Manual replication adds operational complexity and doesn't provide real-time edge caching at the CDN level — Cloud CDN is the simpler, more effective solution.
- D
Use Cloud Interconnect to provide dedicated bandwidth to Asian users
Why wrong: Cloud Interconnect provides private, high-bandwidth connectivity from enterprise networks to GCP — it's not a content delivery solution for public web users.
Quick Answer
The answer is enabling Cloud CDN on the load balancer backend pointing to the Cloud Storage bucket. This is correct because Cloud CDN leverages Google’s globally distributed edge caches to serve static assets like images, JavaScript, and CSS from a point of presence (PoP) closest to the user, drastically reducing latency for Asian users without moving the origin bucket from the US. On the Google Associate Cloud Engineer exam, this scenario tests your understanding of how to improve static asset load times for global users with Cloud CDN, often appearing as a distractor where candidates might mistakenly choose bucket replication or multi-region storage. The common trap is overcomplicating the solution—Cloud CDN is the simplest, most cost-effective fix because it caches content at the edge rather than requiring infrastructure changes. Memory tip: think “CDN = Cache Delivers Nearby,” so when users are far from the origin, cache at the edge.
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.
A global web application serves static assets (images, JavaScript, CSS) from a Cloud Storage bucket via an HTTPS load balancer. Users in Asia report slow load times compared to users in the US where the bucket resides. What is the most effective solution?
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 load balancer backend pointing to the Cloud Storage bucket
Option B is correct because enabling Cloud CDN on the load balancer backend that points to the Cloud Storage bucket caches static assets at Google's globally distributed edge caches. This reduces latency for Asian users by serving content from a nearby point of presence (PoP) rather than from the origin bucket in the US, without requiring any bucket relocation or replication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Move the Cloud Storage bucket to a multi-region bucket in Asia
Why it's wrong here
Moving the bucket to Asia improves Asian users but degrades US users — multi-region improves availability, not necessarily CDN-level edge caching performance.
- ✓
Enable Cloud CDN on the load balancer backend pointing to the Cloud Storage bucket
Why this is correct
Cloud CDN caches content at Google's global edge PoPs. Asian users receive cached assets from the nearest edge location, drastically reducing latency without changing the origin.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that moving or replicating storage to a closer region is the best way to reduce latency, when in fact edge caching (Cloud CDN) is the most effective and cost-efficient solution for static content served globally.
Detailed technical explanation
How to think about this question
Cloud CDN leverages Google's global edge network with over 200+ points of presence (PoPs) worldwide, caching static content at the edge based on cache-control headers and TTLs. When a user in Asia requests a static asset, the edge cache serves it directly if cached, bypassing the origin bucket entirely; this reduces round-trip time from potentially hundreds of milliseconds to under 20 ms for cache hits. A subtle behavior is that Cloud CDN supports signed URLs and cache invalidation, but static assets from Cloud Storage are typically cacheable by default, making this a zero-configuration optimization for most use cases.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. 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?
easy- A.Replicate the Cloud Storage bucket to an Asia region and update DNS to route Asian users to the regional bucket.
- ✓ B.Enable Cloud CDN on the Cloud Storage bucket's load balancer backend.
- C.Deploy Cloud Run instances in Asia regions to serve the static assets.
- D.Increase the Cloud Storage bucket's replication factor to improve throughput.
Why B: 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.
