9.10.1 - Chapter Quiz 1.Match the Ethernet frame field to the proper function.  Fields:  A. Preamble (7 Bytes) and Start of Frame Delimiter (1 Byte)  B. Frame Checksum Sequence (4 Bytes)  C. Destination Address (6 Bytes)  D. Source Address (6 Bytes)  E. Length/Type (2 Bytes)  F. 8 0 2 dot 2 Header and Data (46 to 1500 Bytes)  Functions:  1. Contains the encapsulated data from a higher layer.  2. Identifies the intended recipient.  3. Value equal to or greater than 0x0600 indicates the encapsulated protocol.  5. Used for synchronization between the sending and receiving devices.  6. Used to detect errors in a frame.  7. Identifies the frame's originating NIC or interface.  2.What is a primary function of CSMA/CD in an Ethernet network?  A.Assigns MAC addresses to hosts.  B.Defines the area in which collisions can occur.  C.Identifies the start and end of an Ethernet frame.  D.Provides a method to determine when and how hosts access the Ethernet medium.  E.Creates the header in the Ethernet frame as data is encapsulated.  F.Maps an IP address to a MAC address.  3.What technology is the IEEE 8 0 2 dot 3a c standard specifically designed to accommodate?  A.Simple Network Management Protocol  B.Address Resolution Protocol  C.Virtual Local Area Network  D.Voice over IP  E.Internet Control Message Protocol  4.What is the purpose of media access control?  A.It identifies which workstation has sent a frame.  B.It determines which Layer 3 protocol should handle a frame.  C.It identifies which Ethernet frame format to use on the network.  D.It determines which workstation on a shared medium LAN is allowed to transmit data.  5.How are collisions detected on an Ethernet network?  A.Stations identify the altered FCS field on the colliding packets.  B.The signal amplitude on the networking media is higher than normal.  C.Traffic on the network cannot be detected due to a blockage.  D.The signal amplitude on the networking media is lower than normal.  6.Which Layer 2 sublayer provides service to the network layer of the O S I Model?  A.FCS  B.IEEE 8 0 2 dot 3  C.LLC  D.MAC  7.Refer to the following diagram description to answer the question.  Diagram description:  A PC, a printer, and a router are connected to a hub. The router is also connected to the Internet.  Which devices in the diagram must have a MAC address?  A.Only the PC  B.Only the router  C.PC and router  D.PC, hub, and router  E.PC, printer, and router  8.Refer to the following diagram description to answer the question.  Diagram description:  Four PC's, Host A, Host B, Host C, and Host D, are connected to a hub.  Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D, when Host B wishes to transmit its own frame to Host C. What must Host B do?  A.Host B can transmit immediately since it is connected on its own cable segment.  B.Host B must wait to receive a CSMA transmission from the hub, to signal its turn.  C.Host B must send a request signal to Host A by transmitting an interframe gap.  D.Host B must wait until it is certain that Host A has completed sending its frame.  9.Which of the following are fields in an 8 0 2 dot 3 Ethernet frame? (Choose three.)  A.Source physical address  B.Source logical address  C.Media type identifier  D.Frame check sequence  E.Destination physical address  F.Destination logical address  10.What address type does a switch use to make selective forwarding decisions?  A.Source IP  B.Destination IP  C.Source MAC  D.Destination MAC
