Which two utilities can be used to identify a router experiencing issues?

Pathping and Tracert are both utilities specifically designed to diagnose routing issues in a network by tracing the path packets take to reach their destination.

Pathping combines the functionalities of Ping and Tracert, providing detailed information about the route and measuring the round-trip time as well as packet loss at each hop along the path to the destination. This is especially useful in identifying whether a particular router or network segment is experiencing problems, such as high latency or packet loss.

Tracert, or traceroute on other operating systems, traces the route packets take to a specific destination. It provides visibility into each router (or hop) the packets pass through, which can help identify where in the network a problem may be occurring. If a packet is not reaching its destination, Tracert will show at which hop the packet is failing, indicating a router experiencing issues.

Both of these tools are commonly used by network administrators to troubleshoot connectivity problems and effectively pinpoint problematic routers within a network path.
