Cloud Digital Leader Why cloud technology is transforming business Practice Question
A global e-commerce company needs to deliver content to users quickly regardless of location. Which Google Cloud service can cache content at edge locations to reduce latency?
⚠ Common exam trap
Google Cloud often tests the distinction between services that route traffic (Cloud Load Balancing) and services that cache content (Cloud CDN), leading candidates to confuse load balancing with content delivery.
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
✓
Cloud CDN
Cloud CDN (Content Delivery Network) uses Google's globally distributed edge caches to deliver content from the nearest point of presence (PoP) to the user, significantly reducing latency. It integrates with Cloud Load Balancing and Cloud Storage to cache static and dynamic content, accelerating delivery for a global e-commerce platform.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud Storage
Why it's wrong here
Cloud Storage is a durable object storage service that can host static content, but it does not inherently provide global edge caching. Even with multi-region buckets, requests are routed to the bucket's location, not to a geographically distributed cache, so users far from that region may experience latency. To achieve low-latency global delivery, Cloud Storage must be paired with an external caching layer such as Cloud CDN.
- ✓
Cloud CDN
Why this is correct
Cloud CDN is the correct service because it leverages Google's globally distributed edge points of presence to cache content in close proximity to end users. By reducing the number of round trips back to the origin, it significantly lowers latency and offloads origin traffic. Cloud CDN works with HTTPS load balancing and can use Cloud Storage as its origin, making it ideal for delivering e-commerce site content globally.
- ✗
Cloud Load Balancing
Why it's wrong here
Cloud Load Balancing distributes incoming traffic across multiple backend instances to ensure availability and scalability, but it does not store or cache content itself. Each request is still forwarded to the origin backend, so there is no reduction in network distance for global users. While it can complement a content delivery strategy, load balancing alone does not improve content delivery latency.
- ✗
Cloud Interconnect
Why it's wrong here
Cloud Interconnect establishes high-bandwidth dedicated connections between an on-premises network and Google Cloud, primarily for hybrid cloud networking and reliable data transfer. It does not provide edge caching, nor does it position content closer to internet users. Since Interconnect connects your own infrastructure to Google's network, it has no effect on the latency experienced by public e-commerce consumers around the world.
