Which audit trail is specifically meant for monitoring user-based details for administrators?

The Admin Audit Trail is specifically designed for monitoring user-based details associated with administrators within Marketo Engage. It provides a comprehensive log of all administrative actions taken, allowing organizations to track changes made by users who have administrative privileges. This is crucial for ensuring accountability and security, as it allows for the review of actions like permissions alterations, changes to settings, or modifications to user roles.

In contrast, the other options serve different purposes. The Asset Audit Trail focuses on changes made to marketing assets, while the User Login Audit Trail records login attempts and activity from standard users, not administration actions. Email Campaigns pertain to specific marketing initiatives rather than user-based monitoring. Thus, the Admin Audit Trail stands out as the essential tool for tracking admin-related actions and enhancing oversight within the platform.
