Answer to Question 1

C

Answer to Question 2

A content delivery network (CDN) is a system of hardware and software that stores user data in many different geographical locations and makes those data available on demand.
A CDN provides a specialized type of PaaS but is usually considered in its own category.
A news organization could use a CDN to store copies of its news articles. The CDN vendor replicates articles on servers, possibly worldwide, so as to speed response time. In addition to news articles, CDNs are often used to store and deliver content that seldom changes. For example, the company banner on an organization's Web page might be stored on many CDN servers. Various pieces of the Web page could be obtained from different servers on the CDN.
