CompTIA CASP+ (CAS-004) — Question 526

A company with customers in the United States and Europe wants to ensure its content is delivered to end users with low latency. Content includes both sensitive and public information. The company's data centers are located on the West Coast of the United States. Users on the East Coast of the United States and users in Europe are experiencing slow application response.

Which of the following would allow the company to improve application response quickly?

Answer options

• A. Installing reverse caching proxies in both data centers and implementing proxy autoscaling
• B. Using HTTPS to serve sensitive content and HTTP for public content
• C. Using colocation services in regions where the application response is slow
• D. Implementing a CDN and forcing all traffic through the CDN

Correct answer: D

Explanation

Implementing a CDN (Content Delivery Network) allows for content to be cached closer to users, significantly reducing latency and improving response times for both U.S. East Coast and European users. The other options may help with performance but do not provide the same level of immediate improvement across a wide geographical area as a CDN does.
