1 Which of the following characteristics of TCP is provided by windowing? connectionless data transport flow control * well-known ports best-effort delivery 2 Which of the following protocols operate at the application layer of the OSI model? (Choose two.) FTP * TCP UDP HTTP * 3 Which port numbers are commonly assigned for FTP use? (Choose two.) 19 20 * 21 * 22 4 Which protocol is used to transfer files from computer to computer but is considered connectionless? FTP TFTP * SNMP TCP DHCP 5 What are the features of the User Datagram Protocol (UDP). (Choose three.) no guaranteed delivery of datagrams * connection-oriented provides reliable full-duplex data transmission reliability provided by the application layer * connectionless * utilizes sliding windowing techniques 6 Which protocol can be used to load or retrieve Cisco IOS images to or from a router? SNMP TFTP * UDP TCP 7 During data transfer, what are the main responsibilities of the receiving host? (Choose two.) throughput encapsulation acknowledgment * bandwidth segmentation reassembly * 8 Which of the following services is used to translate a web address into an IP address? DNS * WINS DHCP Telnet 9 Which SNMP component is responsible for using the majority of memory resources? network management system * agents managed devices secure ports 10 What does TCP use to begin the three-way handshaking process? The destination host sends an ACK segment. The sending host sends a SYN segment. * The sending host sends a SYN and ACK segment. The destination host sends a SYN segment. 11 Which of the following SNMP components would a router be considered? network management system agents managed devices * secure ports 12 Which of the following describes the operation of TCP window size? Window size increases as all data transfers. Window size is the TCP process used prepare data for transmission. Window size is decreased if packets are lost. * Window size of 15 means that the next byte expected is byte number 15. 13 End systems use port numbers to select the proper application. What is the smallest port number that can be dynamically assigned by a host system? 1 64 128 256 512 1024 * 14 Which of the following are components of SNMP? (Choose three.) network management system * protocol analyzer managed devices * secure ports agents * protocol inspector 15 Which of the following protocols use TCP? (Choose two.) FTP * DHCP TFTP HTTP * SYN 16 What is the purpose of TCP/UDP port numbers? indicate the beginning of a three-way handshake reassemble the segments into the correct order identify the number of data packets that may be sent without acknowledgment track different conversations crossing the network at the same time * 17 Which TCP/IP layer is responsible for dialog control? application * presentation session transport 18 At which layer of the TCP/IP model does Telnet operate? application * presentation session transport internet network access 19 Which application layer protocol allows network devices to exchange management information? SMTP SNMP * FTP TFTP EIGRP 20 Which protocols can be used to transfer files between systems? (Choose two) TFTP * DNS SNMP FTP * DHCP 21 Which protocol is used by e-mail servers to communicate with each other? FTP HTTP TFTP SMTP * POP SNMP 22 Which protocol is used by FTP to transfer files over the Internet? TCP * SMTP UDP SNMP 23 Which acknowledgement number should be sent by the receiver shown in the graphic? 3 4 6 7 * 9 12 24 Which features allow TCP to reliably and accurately transport and regulate the flow of information from source to destination? (Choose three.) sliding windows * buffers asynchronization sequencing numbers * acknowledgments * segmentation 25 TCP/IP connection-oriented sessions begin with a three-way handshake. Which items describe the handshake process? (Choose three.) acknowledge * synchronize * encapsulate negotiate * create propagate 26 Which type of institution does the domain suffix .org represent? government education network non-profit *
