Enhanced measurement in a web data stream allows for which of the following?

Enhanced measurement in a web data stream is designed to facilitate the automatic collection of additional events without requiring manual setup or adjustments by the user. This feature enables GA4 to gather insights into specific user interactions such as scrolling, outbound clicks, site searches, video engagement, and file downloads seamlessly, making it easier for marketers and analysts to track user behavior effectively.

By leveraging enhanced measurement, organizations can save time and resources, as they do not need to implement individual tags to capture these events. This allows for a more streamlined data collection process, reducing the potential for errors and ensuring that relevant interaction data is captured consistently across the site.

The other options presented do not align with the purpose of enhanced measurement. While real-time updates on user interactions can be an aspect of GA4, it is not a direct function of enhanced measurement. Similarly, manual data entry and custom tag implementation do not fall within the automated capabilities provided by enhanced measurement features.
