Which of the following tools is specifically designed for performance monitoring in Teradata?

The correct choice is Teradata Viewpoint, as it is specifically designed for performance monitoring within the Teradata ecosystem. Teradata Viewpoint provides a comprehensive web-based interface that allows users to monitor various aspects of the Teradata database, including query performance, system health, and resource usage. This tool enables database administrators to gain insights into the performance of the system, identify bottlenecks, and take necessary actions to optimize the database environment.

Teradata Studio, while a useful integrated development environment for developers, focuses more on database development and management rather than performance monitoring. Fastload is an ETL tool used for loading large volumes of data into Teradata tables and doesn't provide performance monitoring capabilities. Listener is typically associated with event processing and monitoring network activities but is not specifically tailored for performance monitoring in the context of Teradata databases.
