Which term describes a gateway technology used to connect and integrate multiple web applications?

• A. Api
• B. Web Shell
• C. Weevely
• D. Web Shell Detector

Answer: (A)

APIs provide the standard way for software components to talk to each other and work together. They define how to request services, what data formats to use (such as JSON or XML), and what actions are available. Because APIs expose well-defined interfaces, multiple web applications can connect to each other through these gateways, enabling data exchange, authentication, and service orchestration across systems. This gateway role—bridging different apps so they can operate together—is why this term is the best fit for describing a mechanism that connects and integrates multiple web applications.

The other terms refer to different concepts: a web shell is a remote command interface left on a compromised server, Weevely is a PHP backdoor for remote access, and a web shell detector is a defensive tool to identify such backdoors. None of these describe a standard means of integrating multiple web applications.
