  1. What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

    • encapsulation
    • flow control
    • access method
    • response timeout
      Explanation:

      In order for two computers to be able to communicate effectively, there must be a mechanism that allows both the source and destination to set the timing of the transmission and receipt of data. Flow control allows for this by ensuring that data is not sent too fast for it to be received properly.

  2. What type of communication will send a message to all devices on a local area network?

    • broadcast
    • multicast
    • unicast
    • allcast
      Explanation:

      Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication. Multicast is a one-to-many communication where the message is delivered to a specific group of hosts. Allcast is not a standard term to describe message delivery.

  3. What process is used to place one message inside another message for transfer from the source to the destination?

    • access control
    • decoding
    • encapsulation
    • flow control
      Explanation:

      Encapsulation is the process of placing one message format into another message format. An example is how a packet is placed in its entirety into the data field as it is encapsulated into a frame.

  4. What process is used to receive transmitted data and convert it into a readable message?

    • access control
    • decoding
    • encapsulation
    • flow control
      Explanation:

      Decoding is the process of receiving transmitted data and reversing the encoding process to interpret the information. An example is a person that listens to a voicemail and decodes the sounds to understand the received message.

  5. Which type of communication will send a message to a group of host destinations simultaneously?

    • broadcast
    • multicast
    • unicast
    • anycast
      Explanation:

      Multicast is a one-to-many communication where the message is delivered to a specific group of hosts. Broadcast communication is a one-to-all communication. A unicast communication is a one-to-one communication. Anycast is an IPv6 term and is the sending of data in a one-to-nearest communication.

  6. Which method allows a computer to react accordingly when it requests data from a server and the server takes too long to respond?

    • encapsulation
    • flow control
    • access method
    • response timeout
      Explanation:

      If a computer makes a request and does not hear a response within an acceptable amount of time, the computer assumes that no answer is coming and reacts accordingly.

  7. Which type of communication will send a message to the nearest device with the same IPv6 address?

    • groupcast
    • anycast
    • allcast
    • typecast

  17. 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.​
      Explanation:

      The TCP/IP internet layer provides the same function as the OSI network layer. The transport layer of both the TCP/IP and OSI models provides the same function. The TCP/IP application layer includes the same functions as OSI Layers 5, 6, and 7.

  18. What is an advantage to using a protocol that is defined by an open standard?

    • A company can monopolize the market.
    • The protocol can only be run on equipment from a specific vendor.
    • An open standard protocol is not controlled or regulated by standards organizations.
    • It encourages competition and promotes choices.
      Explanation:

      A monopoly by one company is not a good idea from a user point of view. If a protocol can only be run on one brand, it makes it difficult to have mixed equipment in a network. A proprietary protocol is not free to use. An open standard protocol will in general be implemented by a wide range of vendors.

  19. 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
      Explanation:

      1. HTTP governs the way that a web server and client interact.
      2. TCP manages individual conversations between web servers and clients.
      3. IP is responsible for delivery across the best path to the destination.
      4. Ethernet takes the packet from IP and formats it for transmission.

  20. Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.)

    • data link
    • network
    • physical
    • session
    • transport
      Explanation:

      The OSI transport layer is functionally equivalent to the TCP/IP transport layer, and the OSI network layer is equivalent to the TCP/IP internet layer. The OSI data link and physical layers together are equivalent to the TCP/IP network access layer. The OSI session layer (with the presentation layer) is included within the TCP/IP application layer.

  21. 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.
      Explanation:

      An advantage of network devices implementing open standard protocols, such as from the TCP/IP suite, is that clients and servers running different operating systems can communicate with each other. Open standard protocols facilitate innovation and competition between vendors and across markets, and can reduce the occurrence of monopolies in networking markets.

  22. 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
      Explanation:

      The TCP/IP model consists of four layers: application, transport, internet, and network access. The OSI model consists of seven layers: application, presentation, session, transport, network, data link, and physical. The top three layers of the OSI model: application, presentation, and session map to the application layer of the TCP/IP model.

  23. What is a function of the transport layer?

    • provides a data path or route to move messages through an internetwork
    • exchanges frames between network devices
    • executes ordered and reliable delivery of data between source and destination hosts
    • contains protocols for process-to-process communications
      Explanation:

      The transport layer of both the OSI model and TCP/IP model provides ordered and reliable delivery of data between source and destination hosts.

  24. Which layer of the TCP/IP model provides a route to forward messages through an internetwork?

    • application
    • network access
    • internet
    • transport
      Explanation:

      The OSI model network layer corresponds directly to the internet layer of the TCP/IP model and is used to describe protocols that address and route messages through an internetwork.

  25. A web client is receiving a response for a web page from a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to decode the received transmission?

    • Ethernet, IP, TCP, HTTP
    • HTTP, TCP, IP, Ethernet
    • Ethernet, TCP, IP, HTTP
    • HTTP, Ethernet, IP, TCP
      Explanation:

      1. HTTP governs the way that a web server and client interact.
      2. TCP manages individual conversations between web servers and clients.
      3. IP is responsible for delivery across the best path to the destination.
      4. Ethernet takes the packet from IP and formats it for transmission.

    Cisco ITN CCNA 1 v6.0 Chapter 3 Exam Beta Answer R&S 2018 2019 001

    • 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.
      Explanation:

      In order to send data to ServerB, HostA will generate a packet that contains the IP address of the destination device on the remote network and a frame that contains the MAC address of the default gateway device on the local network.

  52. A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

    • the MAC address of the destination host
    • the network domain of the destination host
    • the MAC address of the default gateway
    • the IP address of the default gateway
      Explanation:

      A frame is encapsulated with source and destination MAC addresses. The source device will not know the MAC address of the remote host. An ARP request will be sent by the source and will be responded to by the router. The router will respond with the MAC address of its interface, the one which is connected to the same network as the source.

  53. 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
      Explanation:

      At the transport layer, a host computer will de-encapsulate a segment to reassemble data to an acceptable format by the application layer protocol of the TCP/IP model.

  54. 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
      Explanation:

      The default gateway is the IP address of an interface on the router on the same network as the sending host.

  55. Refer to the exhibit. ServerB is attempting to contact HostA. Which two statements correctly identify the addressing that ServerB will generate in the process? (Choose two.)

    • ServerB will generate a packet with the destination IP address of RouterB.
    • ServerB will generate a frame with the destination MAC address of SwitchB.
    • ServerB will generate a packet with the destination IP address of RouterA.
    • ServerB will generate a frame with the destination MAC address of RouterB.
    • ServerB will generate a packet with the destination IP address of HostA.
    • ServerB will generate a frame with the destination MAC address of RouterA.
      Explanation:

      In order to send data to HostA, ServerB will generate a packet that contains the IP address of the destination device on the remote network and a frame that contains the MAC address of the default gateway device on the local network.

  56. Which PDU is processed when a host computer is de-encapsulating a message at the internet layer of the TCP/IP model?

    • bits
    • frame
    • packet
    • segment
      Explanation:

      At the internet layer, a host computer will de-encapsulate a packet to reassemble data to an acceptable format by the transport layer protocol of the TCP/IP model.

  57. A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a packet to indicate the destination?

    • the IP address of the destination server
    • the MAC address of the destination server
    • the MAC address of the default gateway
    • the IP address of the default gateway
      Explanation:

      A packet is encapsulated with source and destination IP addresses. The source device will not know the MAC address of the host if the host is on a remote network. The source device in this case uses the destination MAC address of the default gateway within the frame, not the packet.

  58. At which layer of the OSI model would a logical address be added during encapsulation?

    • physical layer
    • data link layer
    • network layer
    • transport layer
      Explanation:

      Logical addresses, also known as IP addresses, are added at the network layer. Physical addresses are edded at the data link layer. Port addresses are added at the transport layer. No addresses are added at the physical layer.
