CCNA 1 Chapter 3 Exam Answer v5 & v5.02 2015 (100%)

1. A computer in a given network is communicating with a specific group of computers. What type of communication is this?

  • broadcast
  • multicast
  • unicast
  • ARP
  • HTTP

2. 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

3. Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?

  • HTTP
  • ARP
  • TCP
  • DHCP

4. A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client?

  • DHCP
  • TCP
  • HTTP
  • ARP

5. 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

6. 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

7. Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

  • 802.1
  • 802.11
  • 802.3
  • 802.2

8. 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.

9. What is a function of Layer 4 of the OSI model?

  • to specify the packet type to be used by the communications
  • to apply framing information to the packet, based on the attached media
  • to represent data to the user, including encoding and dialog control
  • to describe the ordered and reliable delivery of data between source and destination

10. 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.​

11. What is a benefit of using a layered model for network communications?

  • fostering competition among device and software vendors by enforcing the compatibility of their products
  • enhancing network transmission performance by defining targets for each layer
  • avoiding possible incompatibility issues by using a common set of developing tools
  • simplifying protocol development by limiting every layer to one function

12. What is the general term that is used to describe a piece of data at any layer of a networking model?

  • frame
  • packet
  • protocol data unit
  • segment

13. Which PDU format is used when bits are received from the network medium by the NIC of a host?

  • file
  • frame
  • packet
  • segment

14. At which layer of the OSI model would a logical address be encapsulated?

  • physical layer
  • data link layer
  • network layer
  • transport layer

15. Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

  • Data is sent from the internet layer to the network access layer.
  • Packets are sent from the network access layer to the transport layer.
  • Segments are sent from the transport layer to the internet layer.
  • Frames are sent from the network access layer to the internet layer.

16. What statement describes the function of the Address Resolution Protocol?

  • ARP is used to discover the IP address of any host on a different network.
  • ARP is used to discover the IP address of any host on the local network.
  • ARP is used to discover the MAC address of any host on a different network.
  • ARP is used to discover the MAC address of any host on the local network.

17. Which address provides a unique host address for data communications at the internet layer?

  • data-link address
  • logical address
  • Layer 2 address
  • physical address

18. 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

19. Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?

  • ARP
  • TCP
  • UDP
  • DHCP

20. If the default gateway is configured incorrectly on the host, what is the impact on communications?

  • The host is unable to communicate on the local network.
  • The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
  • The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.
  • There is no impact on communications.

21. Match the description to the organization. (Not all options are used.)
