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 uses Google's global edge network to cache content close to users, reducing latency for media delivery.
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 CDN
Why this is correct
Cloud CDN caches content at Google's globally distributed edge points of presence, terminating user requests close to their location. This directly satisfies the worldwide low-latency requirement by serving cached video from the nearest edge rather than the origin, reducing round-trip time.
- ✗
Cloud Storage
Why it's wrong here
Cloud Storage holds objects in regional or multi-regional buckets; it does not replicate or cache those objects at edge points of presence, so requests still traverse to the bucket location. It is tempting because it is the origin store for video files, and would be correct as the backend bucket that a CDN pulls from.
- ✗
Cloud Load Balancing
Why it's wrong here
Cloud Load Balancing distributes incoming connections across backends using global anycast VIPs, but it forwards traffic to origin backends rather than caching responses at edge locations. It is tempting because global external Application Load Balancers do terminate at Google's edge, and would be correct for routing users to healthy regional backends.
- ✗
Cloud Interconnect
Why it's wrong here
Cloud Interconnect provides dedicated private connectivity between on-premises networks and Google Cloud, terminating at peering locations rather than caching content near end users. It is tempting because it reduces latency and egress costs for hybrid traffic, and would be correct for private, high-bandwidth links between a corporate data centre and a VPC.
