Which of the following tools would BEST be used to troubleshoot storage latency issues on a Windows server?

Ping is a network utility used to test network connectivity and latency to a host, not storage performance on a local server.

Sysmon (System Monitor) is an advanced monitoring tool that logs system activity such as process creation, network connections, and file modifications, primarily for security auditing, not direct storage latency measurement.

Ipconfig is a command-line utility used to display current TCP/IP network configuration values and modify DHCP and DNS settings, unrelated to storage performance.

Perfmon (Performance Monitor) is a comprehensive Windows tool that provides real-time and historical data on system performance, including specific counters for disk I/O, queue lengths, and latency metrics that are crucial for identifying storage bottlenecks. It allows detailed analysis of storage subsystem performance.
