What solution can improve website speed and performance in case of high traffic due to a disaster?

A content delivery network (CDN) is an effective solution for improving website speed and performance, especially during high traffic situations, such as those that may arise during a disaster. A CDN works by distributing and caching content across a network of servers located in various geographical locations. This approach allows end-users to access data from the server that is closest to them, reducing latency and improving loading times. When a surge in traffic occurs, particularly due to unexpected events or disasters, the CDN can handle the increased load by offloading requests from the origin server, thereby enhancing the website's availability and reliability.

In contrast, other options such as a web application firewall (WAF) provide security features to protect websites from attacks and vulnerabilities but do not fundamentally enhance performance during high traffic. Data loss prevention (DLP) focuses on safeguarding sensitive information from unauthorized access or leaks, which does not address performance issues. Network access control (NAC) is concerned with security policies regarding user access and device compliance on a network, and while it contributes to security management, it does not directly impact website speed or performance.

By leveraging a CDN, organizations can ensure that their websites remain responsive and fast, even under the duress of heavy traffic, resulting in a better user experience and
