What kind of applications can connectors sync data activities with?

The correct choice specifies that connectors can sync data activities with both Account Engagement (AE) applications and third-party applications. This reflects the versatility of connectors in integrating data across different platforms.

Connectors are designed to facilitate the flow of information between various systems, allowing for a seamless exchange of data. This is particularly important in marketing and sales environments where data consistency across various applications is crucial for effective campaigns, reporting, and user engagement.

By enabling synchronization with both internal AE applications and external third-party applications, organizations can leverage their existing data and enhance their marketing strategies. This broad compatibility means teams can utilize a variety of tools and platforms while ensuring that their data is centralized and up to date, thus supporting better decision-making and more cohesive marketing initiatives.
