This GCDL practice question tests your understanding of why cloud technology is transforming business. 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 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?
Cloud Storage
Why wrong: Cloud Storage stores objects but does not inherently cache at edge locations.
Cloud CDN
Cloud CDN uses global edge caches to reduce latency for content delivery.
Cloud Load Balancing
Why wrong: Load balancing distributes traffic but does not cache content.
Cloud Interconnect
Why wrong: Cloud Interconnect provides dedicated connectivity, not caching.
Answer choices
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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 stores objects but does not inherently cache at edge locations.
Cloud CDN
Why this is correct
Cloud CDN uses global edge caches to reduce latency for content delivery.

Cloud Load Balancing
Why it's wrong here
Load balancing distributes traffic but does not cache content.
Cloud Interconnect
Why it's wrong here
Cloud Interconnect provides dedicated connectivity, not caching.
Common exam traps
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.
Detailed technical explanation
Cloud CDN leverages Google's global network of over 150 edge points of presence (PoPs) to cache content, using HTTP/2 and QUIC protocols for optimized delivery. It supports cache modes like FORCE_CACHE_ALL and USE_ORIGIN_HEADERS, and can invalidate cached content via cache keys or TTL settings. In a real-world e-commerce scenario, product images and static assets are cached at the edge, reducing origin load and improving page load times for users in remote regions.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
