CompTIA Network+ (N10-009) — Question 482

Which of the following used to store and deliver content to clients in a geographically distributed manner using edge servers?

Answer options

• A. Load balancer
• B. CDN
• C. DNS server
• D. SAN

Correct answer: B

Explanation

The correct answer is B, CDN (Content Delivery Network), as it specifically refers to a system designed to deliver content to users with high availability and performance by using a network of servers distributed geographically. Options A, C, and D do not serve this purpose; a Load balancer (A) manages traffic distribution, a DNS server (C) translates domain names to IP addresses, and a SAN (D) is a storage network used for block-level storage rather than content delivery.
