  • The network administrator wants to determine if connectivity can be established from a non-directly connected network.
  • The network administrator suspects a virus because the ping command did not work.
  • The network administrator wants to verify the IP address configured on router R2.

  • when it is from a subset of users
  • during low utilization times
  • when it is on the main network segment only

  • H3 is not connected properly to the network.
  • Performance between the networks is within expected parameters.
  • Something is causing a time delay between the networks.
  • Connectivity between H1 and H3 is fine.
  • Something is causing interference between H1 and R1.

10. When should an administrator establish a network baseline?

  • when there is a sudden drop in traffic
  • at regular intervals over a period of time
  • when the traffic is at peak in the network
  • at the lowest point of traffic in the network
