Selected Answer: D
Given the requirement to improve application response times quickly for users in the United States (East Coast) and Europe, implementing a CDN (option D) is the most efficient solution. A CDN leverages caching and content distribution to deliver content with low latency by serving it from edge servers located close to end users. This approach ensures that both sensitive and public content can be delivered swiftly across different geographic regions, optimizing user experience without requiring significant infrastructure changes or delays in deployment.

Selected Answer: C
CDN offers itself, but my worry is the sensitive information. Additionally there are only two regions, east coast and Europe. I think i'm going to go with C on this one. I may be wrong though, everything speaks for CDN other than that
