Which of the following Pega components is used for integrating with external systems?

The choice of Connectors as the correct answer is based on their specific function within the Pega platform. Connectors are designed to facilitate integration with external systems, enabling Pega applications to communicate with external data sources, services, and applications. They allow Pega to send and receive data to and from third-party systems, which is essential for building applications that require interaction with various external entities.

Connectors can utilize various protocols such as HTTP, REST, SOAP, and more, depending on the requirements of the external system. They help streamline the process of integrating these systems into Pega applications, making it easier for developers to manage external interactions and data transfer.

The other options, while integral to the Pega ecosystem, serve different purposes. Activities are primarily used for executing a series of steps to perform specific logic or actions within the Pega application. User interfaces focus on the front-end design and user experience, allowing users to interact with the application. Data pages are utilized for managing and displaying data, but they do not handle the integration aspect directly. Hence, Connectors stand out as the dedicated component for integrating with external systems.
