Database Visibility provides metrics on the performance of your database and helps troubleshoot performance-related issues. Database Visibility consists of four main components: Database Agent, Collector, Controller, and Events Service (on-premises only). The Database Agent is a standalone Java program that collects performance metrics about your database instances and database servers. The Collector is the process that runs within the Database Agent to collect performance metrics about your database instances and database servers. The Controller is the central interface where you can see all your database instances and database server performance metrics. The Events Service stores high volumes of metric data.

According to the Overview of Database Visibility, the following types of information are sent to the Controller:

• Database-level metrics, such as the number of queries processed and other database statistics
• Names and attributes of all sessions, clients, queries, and other objects on the monitored system

The following types of information are sent to the Events Service:

• Time that each query spends at each wait state
• Individual query statistics for databases that support it
• Information about individual execution plans in databases that support it

Therefore, B (Average Number of Slow Connections) and C (Top Leaked Connections) are two stats that are available in Database Visibility. References:

According to the Upgrade the Java Agent document1, one of the reasons to upgrade AppDynamics agents is to resolve agent issues, such as bugs, performance problems, or compatibility issues withthe Controller or the monitored application. Another reason to upgrade AppDynamics agents is to take advantage of new features, such as enhanced metrics, dashboards, alerts, or integrations, that are introduced in newer agent versions. Therefore, the correct answer is A and D. Database issues and application upgrade are not directly related to the agent upgrade, unless they affect the agent functionality or compatibility. References:

When you have a custom dashboard that has only one widget, you can delete that widget by clicking the Delete Widget button on the widget properties panel. This will remove the widget from the dashboard, but it will not delete the dashboard itself. You can still view and edit the dashboard from the Controller UI or the Events Service.

According to the Create and Manage Custom Dashboards and Templates - AppDynamics, when you delete a widget from a custom dashboard, AppDynamics does not create a blank widget because empty dashboards are not allowed. Instead, it preserves the existing widgets on the dashboard and displays them in a single row.

Therefore, B (The widget is deleted, but an empty custom dashboard is maintained) is true. References:
