Which service is an example of Edge Services in Oracle Cloud Infrastructure?

The correct answer, identifying a service that exemplifies Edge Services in Oracle Cloud Infrastructure, is Web Application Firewall.

Edge Services refer to the functionalities that provide security, traffic management, and other capabilities at the point where cloud services connect to the internet or to other networks. The Web Application Firewall (WAF) is specifically designed to protect web applications by filtering and monitoring HTTP traffic between a web application and the internet, helping to safeguard against common web vulnerabilities.

In contrast, Virtual Cloud Network (VCN), Virtual Firewall, and Cloud Storage serve different purposes within Oracle Cloud Infrastructure. VCN is primarily a networking resource allowing users to build a secure, isolated environment to host cloud resources. A Virtual Firewall is used for implementing security rules and access controls within the network but does not operate as an edge function. Cloud Storage provides scalable storage solutions for data but does not inherently provide edge services like traffic management and protection at network boundaries. This distinction clarifies why the Web Application Firewall is the appropriate example of Edge Services in Oracle Cloud Infrastructure.
