What is used to monitor and manage the Exchange Transport service’s performance?

Performance Monitor is the correct choice for monitoring and managing the Exchange Transport service's performance. This tool is specifically designed to track system performance over time and allows administrators to view real-time performance metrics.

In the context of Exchange Server, Performance Monitor can provide detailed statistics relating to various aspects of the Transport service, such as message queue lengths, delivery rates, and resource utilization. This information is invaluable for identifying bottlenecks, troubleshooting issues, and optimizing the configuration for better throughput and reliability.

While Event Viewer provides logs and is useful for troubleshooting by showing errors and warnings, it is not primarily focused on ongoing performance metrics. The System Configuration Utility is also not designed for performance monitoring; it primarily helps in managing startup configurations and services. Task Manager can display real-time usage of CPU, memory, and processes, but it does not offer the detailed performance insights specific to the Exchange Transport service that Performance Monitor does. Thus, the specialized capabilities of Performance Monitor make it the appropriate tool for this purpose.
