The server issending the file using 100-byte segments. How many segments will the server send before itrequires an acknowledgment from the PC?1 segment10 segments*100 segments1000 segments2A host device needs to send a large video file across the network while providing datacommunication to other users. Which feature will allow different communication streams tooccur at the same time, without having a single data stream using all available bandwidth?multiplexing *window sizeacknowledgmentsport numbers3A technician wishes to use TFTP to transfer a large file from a file server to a remote router.Which statement is correct about this scenario?The file is segmented and then reassembled in the correct order by TCP.The file is not segmented, because UDP is the transport layer protocol that is used by TFTP.Large files must be sent by FTP not TFTP.The file is segmented and then reassembled in the correct order at the destination, ifnecessary, by the upper-layer protocol.*4By CCNA5.NETDownloaded from MIPDF.COM5Which scenario describes a function provided by the transport layer?A student is using a classroom VoIP phone to call home. The unique identifier burned into the phone isa transport layer address used to contact another network device on the same network.A corporate worker is accessing a web server located on a corporate network. The transport layerformats the screen so the web page appears properly no matter what device is being used to view theweb site.A student has two web browser windows open in order to access two web sites. The transportlayer ensures the correct web page is delivered to the correct browser window.*A student is playing a short web-based movie with sound. The movie and sound are encoded withinthe transport layer header.6Which transport layer feature is used to guarantee session establishment?UDP ACK flagTCP 3-way handshake*UDP sequence numberTCP port number7What is the complete range of TCP and UDP well-known ports?0 to 255256 – 10230 to 1023*1024 – 491518Which two TCP header fields are used to confirm receipt of data?checksumacknowledgment number*FIN flagsequence number*SYN flagBy CCNA5.NETDownloaded from MIPDF.COM9What is a beneficial feature of the UDP transport protocol?acknowledgment of received datatracking of data segments using sequence numbersfewer delays in transmission*the ability to retransmit lost data10Which two flags in the TCP header are used in a TCP three-way handshake to establishconnectivity between two network devices? (Choose two.)RSTFINSYN*ACK*URGPSH11What happens if the first packet of a TFTP transfer is lost?The TFTP application will retry the request if a reply is not received.*The next-hop router or the default gateway will provide a reply with an error code.The client will wait indefinitely for the reply.The transport layer will retry the query if a reply is not received.12Compared to UDP, what factor causes additional network overhead for TCP communication?the identification of applications based on destination port numbersthe checksum error detectionthe encapsulation into IP packetsnetwork traffic that is caused by retransmissions*13By CCNA5.NETDownloaded from MIPDF.COM14Which factor determines TCP window size?the amount of data the destination can process at one time*the number of services included in the TCP segmentthe amount of data the source is capable of sending at one timethe amount of data to be transmitted15By CCNA5.NETDownloaded from MIPDF.COM16During a TCP session, a destination device sends an acknowledgment number to the sourcedevice. What does the acknowledgment number represent?the last sequence number that was sent by the sourceone number more than the sequence numberthe next byte that the destination expects to receive*the total number of bytes that have been received17What is a socket?the combination of the source and destination sequence numbers and port numbersthe combination of the source and destination sequence and acknowledgment numbersthe combination of a source IP address and port number or a destination IP address and portnumber*the combination of the source and destination IP address and source and destination Ethernet address18Fill in the blank.During a TCP session, theserver.”SYN” field is used by the client to request communication with the19Fill in the blank using a number.A total of “4” messages are exchanged during the TCP session termination process between theclient and the server.20A host device sends a data packet to a web server via the HTTP protocol. What is used by thetransport layer to pass the data stream to the proper application on the server?source port numberdestination port number*sequence numberacknowledgment21What does a client do when it has UDP datagrams to send?It just sends the datagrams.*It queries the server to see if it is ready to receive data.It sends a simplified three-way handshake to the server.It sends to the server a segment with the SYN flag set to synchronize the conversation.22What does a client application select for a TCP or UDP source port number?a predefined value in the dynamic port rangea predefined value in the range of the registered portsa predefined value in the well-known port rangea random value in the dynamic port range
