What does the command 'traceroute' help identify?

The command 'traceroute' is primarily used to determine the path that packets take across an IP network to reach a specific destination. It provides a detailed list of all the intermediate devices (routers) that the data traverses before arriving at its endpoint. By doing so, it helps network administrators identify any points of failure or latency issues along the route. The output of 'traceroute' includes the IP addresses of each hop and the time taken for the packets to travel to those hops, which can be crucial for diagnosing connectivity issues and performance problems within a network.

The other options focus on different aspects of network management, such as data transfer amounts, server health, and bandwidth usage, which are not the primary function of the 'traceroute' command.
