What does Google Cloud CDN provide?

Correct answer: Global content delivery network for caching and serving content from edge locations near users

Option D is correct because Google Cloud CDN is a globally distributed content delivery network that caches static and dynamic content at edge points of presence close to end users, reducing latency and origin server load. Option A is wrong because database services are provided by products such as Cloud SQL, Cloud Spanner, and Firestore, not by Cloud CDN. Option B is wrong because email services are not part of Cloud CDN; Google Workspace provides email capabilities. Option C is wrong because virtual machines are provided by Compute Engine, which is a separate infrastructure service unrelated to content delivery.
