Questions and Answers

What is the purpose of the traceroute program?

  • To measure the bandwidth of the network connection
  • To establish a secure connection between sender and receiver
  • To send packets from the destination to the source
  • To provide delay measurements from source to router along the Internet path towards the destination (correct)

    • How many probes does the traceroute program typically send to a router on the path towards the destination?

  • One probe
  • Four probes
  • Three probes (correct)
  • Two probes

    • What does a lost probe in a traceroute typically indicate?

  • Network security breach
  • Router failure
  • Packet loss (correct)
  • Internet congestion

    • In traceroute measurements, what is the significance of 'ms' values after each router IP address?
