Difficulty: MediumMicrosoft Command-Line Tools

A desktop technician is troubleshooting network performance issues reported by a user accessing a remote server across multiple routed subnets. The technician wants to identify which specific router hop along the path is introducing latency and packet loss by sending packets to each intermediate hop over a sampling period. Which Windows command-line utility should the technician use?

  1. pathpingAnswer
  2. B
    traceroute
  3. C
    ping -t
  4. D
    tracert

Answer

The pathping command should be used to trace the route and measure packet loss per router hop.
The pathping utility is specifically designed to combine the functionality of ping and tracert. It traces the route to the target IP address and then pings each intermediate router over a test period to compute latency and packet loss statistics for every hop along the path.

Step-by-Step Solution

1
Analyze the requirement for identifying packet loss and latency at intermediate network hops over a sample interval.
Recognize that a hybrid tool combining route tracing with statistics collection is required.
Standard ICMP pinging tests only the end destination, while tracert tests path latency at a single instant without long-term packet loss statistics.
2
Select the appropriate native Windows command-line diagnostic tool.
Identify pathping as the tool designed to ping intermediate routers over a time interval.
pathping sends multiple pings to each hop along the route to generate comprehensive latency and packet loss statistics per router node.
