    120s
  • Q11
    How would you modify a device on layer 1?
    Send IP traffic through the network to translate the IP address into a MAC address so traffic can be forwarded
    Log onto a live video and stream it to a workstation via User Datagram Protocol (UDP)
    Create an IP address reservation for a client’s workstation and have the workstation obtain the IP via Dynamic Host Configuration Protocol (DHCP)
    Run a fiber cable from one end of campus to the other to connect two switches together.

  • Q12
    Which action takes place on layer 3?
    Internet Protocol (IP) addresses are translated to MAC addresses via Address Resolution Protocol (ARP).
