Dashboards display summarized information of activity on which two items?

The correct answer highlights that dashboards in Marketing Cloud Social are designed to present summarized information regarding Social Accounts and Topic Profiles. By focusing on these two elements, the dashboards allow users to monitor engagement metrics and performance across different social media platforms effectively.

Social Accounts represent the various social media profiles managed within the Marketing Cloud, facilitating an analysis of activities associated with each account, including interactions and audience demographics. Topic Profiles, on the other hand, aggregate data related to specific themes or discussions across social media channels, providing insights into trending topics, sentiment analysis, and the overall reach of related content.

These two components are critical for social media marketers as they help in tracking the effectiveness of campaigns and understanding audience interests, which can inform future strategies. Collectively, they enable users to see an overview of how different accounts are performing and the general public's engagement with various topics, thereby streamlining decision-making processes in social media marketing.

The other options, while relevant to social media activities, do not encompass the breadth of insights provided by the combination of Social Accounts and Topic Profiles that a dashboard offers.
