    • encapsulation
    • flow control
    • access method
    • response timeout
  • 2 What type of communication will send a message to all devices on a local area network?

    • broadcast
    • multicast
    • unicast

  • 4 A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?

    • HTTP, IP, TCP, Ethernet
    • HTTP, TCP, IP, Ethernet
    • Ethernet, TCP, IP, HTTP
    • Ethernet, IP, TCP, HTTP
  • 5 Which statement is correct about network protocols?

    • Network protocols define the type of hardware that is used and how it is mounted in racks.
    • They define how messages are exchanged between the source and the destination.
    • They all function in the network access layer of TCP/IP.
    • They are only required for exchange of messages between devices on remote networks.
  • 6 Which statement is true about the TCP/IP and OSI models?

    • The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
    • The TCP/IP network access layer has similar functions to the OSI network layer.
    • The OSI Layer 7 and the TCP/IP application layer provide identical functions.
    • The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.
  • 7 What is an advantage of using standards to develop and implement protocols?

    • A particular protocol can only be implemented by one manufacturer.
    • Products from different manufacturers can interoperate successfully.
    • Different manufacturers are free to apply different requirements when implementing a protocol.
    • Standards provide flexibility for manufacturers to create devices that comply with unique requirements.
  • 8 What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)

    • ARP
    • DHCP
    • DNS
    • FTP
    • NAT
    • PPP
  • 9 What are proprietary protocols?



    • protocols developed by private organizations to operate on any vendor hardware
    • protocols that can be freely used by any organization or vendor
    • protocols developed by organizations who have control over their definition and operation
    • a collection of protocols known as the TCP/IP protocol suite

    • 10 What is an advantage of network devices using open standard protocols?

      • Network communications is confined to data transfers between devices from the same vendor.
      • A client host and a server running different operating systems can successfully exchange data.
      • Internet access can be controlled by a single ISP in each market.
      • Competition and innovation are limited to specific types of products.
    • 11 Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?

      • only application and Internet layers
      • only Internet and network access layers
      • only application, Internet, and network access layers
      • application, transport, Internet, and network access layers
      • only application, transport, network, data link, and physical layers
      • application, session, transport, network, data link, and physical layers
    • 12 Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)

      • application
      • presentation
      • session
      • transport
      • data link
      • physical
      • network
    • 13 At which layer of the OSI model would a logical address be encapsulated?

      • physical layer
      • data link layer
      • network layer
      • transport layer
    • 14 Which PDU format is used when bits are received from the network medium by the NIC of a host?

      • file
      • frame
      • packet
      • segment
    • 15 Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?

      • bits
      • frame
      • packet
      • segment
    • 16 Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process? (Choose two.)

      CCNA1 Chapter 3 v5.1 003
      • A packet with the destination IP address of RouterB.
      • A frame with the destination MAC address of SwitchA.
      • A packet with the destination IP address of RouterA.
      • A frame with the destination MAC address of RouterA.
      • A packet with the destination IP address of ServerB.
      • A frame with the destination MAC address of ServerB.
    • 17 Which address does a NIC use when deciding whether to accept a frame?

      • source IP address
      • source MAC address
      • destination IP address
      • destination MAC address
      • source Ethernet address
    • 18 What will happen if the default gateway address is incorrectly configured on a host?

      • The host cannot communicate with other hosts in the local network.
      • The switch will not forward packets initiated by the host.
      • The host will have to use ARP to determine the correct address of the default gateway.
      • The host cannot communicate with hosts in other networks.
      • A ping from the host to 127.0.0.1 would not be successful.
    • 19 Which characteristic describes the default gateway of a host computer?

      • the logical address of the router interface on the same network as the host computer
      • the physical address of the switch interface connected to the host computer
      • the physical address of the router interface on the same network as the host computer
      • the logical address assigned to the switch interface connected to the router
