Fostering competition among device and software vendors by enforcing the compatibility of their productsSimplifying protocol development by limiting every layer to one functionAvoiding possible incompatibility issues by using a common set of developing tools 2 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? TCPDHCPARP 3 What is the general term that is used to describe a piece of data at any layer of a networking model? Protocol data unitPacketFrame 4 A computer in a given network is communicating with a specific group of computers. What type of communication is this? BroadcastMulticastUnicast 5 Which address provides a unique host address for data communications at the internet layer? Physical addressLayer 2 addressLogical address 6 Which address does a NIC use when deciding whether to accept a frame? Source Ethernet addressDestination MAC addressSource IP address 7 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 first three OSI layers describe general services that are also provided by the TCP/IP internet layerThe OSI Layer 7 and the TCP/IP application layer provide identical functions 8 Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client? ARPTCPDHCP 9 Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network? Segments are sent from the transport layer to the internet layerFrames are sent from the network access layer to the internet layerData is sent from the internet layer to the network access layer 10 Which PDU format is used when bits are received from the network medium by the NIC of a host? PacketFrameSegment 11 Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer? 802. 11802. 3802. 1 12 What are proprietary protocols? A collection of protocols known as the TCP/IP protocol suiteProtocols developed by organizations who have control over their definition and operationProtocols developed by private organizations to operate on any vendor hardware 13 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 hostThe IP address of the default gatewayThe MAC address of the default gateway 14 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.There is no impact on communications.The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks. 15 At which layer of the OSI model would a logical address be encapsulated? Phsical layerNetwork layerData link layer 16 This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers. IANAISOCIEEE 17 This organization is the largest developer of international standards in the world for a wide variety of products and services. It is known for its Open Systems Interconnection (OSI) reference model. IANAIEEEISO 18 This organization promotes the open development, evolution and use of the Internet throughout the world. ISOCISOIANA 19 What is a function of Layer 4 of the OSI model? To represent data to the user, including encoding and dialog controlTo specify the packet type to be used by the communicationTo describe the ordered and reliable delivery of data between source and destination 20 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? Ethernet, IP, TCP, HTTPHTTP, TCP, IP, EthernetHTTP, IP, TCP, Ethernet 21 What statement describes the function of the ARP? ARP is used to discover the MAC address of any host on the local networkARP is used to discover the MAC address of any host on a different networkARP is used to discover the IP address of any host on the local network 22 What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly? Access methodFlow controlResponse timeout 23 What is an advantage of network devices using open standard protocols? A client host and a server running different operating systems can successfully exchange dataCompetition and innovation are limited to specific types of productsInternet access can be controlled by a single ISP in each market A mistake in this Quiz ?
