Cisco Discovery - DHomesb Module 6 - V.4 in english.Q.1 A user types www.cisco.com into a web browser address textbox. What does www.cisco.comrepresent? the IP address of a web server a physical network address the closest router interface to the source the source IP address in the data transmissionQ.2 What type of server would use IMAP? DNS DHCP e-mail FTP Telnet webQ.3 Which type of server would most likely be used first by a network client in a corporateenvironment? DNS DHCP e-mail FTP Telnet web
Q.4 Which protocol is used by FTP to transfer files over the Internet? TCP SMTP UDP SNMPQ.5 Which protocols are TCP/IP application layer protocols? (Choose two.) UDP FTP IP SMTP TCPQ.6 Which of the following are layers of the TCP/IP model? (Choose three.) Application Physical Internet Network Access PresentationQ.7 You are creating a network-based video game. What influences your decision about which transportprotocol to use for the application? UDP will not disrupt the game to retransmit dropped packets. TCP provides extra acknowledgements that will ensure smooth video delivery. Both TCP and UDP can be used simultaneously to ensure speed and guaranteed delivery. Both TCP and UDP may slow transmission and disrupt game operation, so no transport protocol
should be used.Q.8 Whenever e-mail clients send letters, what device is used to translate the domain names into theirassociated IP addresses? Uniform Resource Locator Network redirector server SNMP server DNS serverQ.9 Which application is most likely used to translate www.cisco.com to 184.108.40.206? DHCP DNS FTP HTTP POP SMTPQ.10 Refer to the graphic. Which protocol is used to access this website?
IM FTP HTTP SNMP VoIPQ.11 Which port number is used by SMTP? 20 21 25 26 110Q.12 Which protocol is used by e-mail servers to communicate with each other? FTP HTTP TFTP SMTP POP SNMPQ.13 What client software enables logged in users to communicate with other logged in users in realtime? blog e-mail
web mail instant messagingQ.14 An Internet server is running both FTP and HTTP services. How does the server know which ofthese applications should handle an incoming segment? The packet header identifies it as an HTTP or FTP packet. The data in the segment is specially formatted for either HTTP or FTP. The segment destination port number identifies the application that should handle it. The source port number is associated with one of these well known server applications.Q.15 What term is used to describe how TCP/IP protocols are layered and interact to format, address,and transmit information across a network? protocol hierarchy protocol modeling protocol stack protocol layeringQ.16 What three items are contained in an Ethernet frame? (Choose three.) source IP address source MAC address destination IP address destination MAC address error-checking informationQ.17 What information is contained in an IP header? source and destination IP addresses
source and destination MAC addresses only destination IP and MAC addresses both source and destination IP and MAC addressesQ.18 Cabling issues are associated with which OSI layer? 4 2 1 3Q.19 A device receives an Ethernet frame and recognizes the MAC address as its own. What does thedevice do to the message to get to the encapsulated data? removes the IP header removes the TCP header passes data to the application layer removes the Ethernet header and trailerQ.20 A client has decoded a frame and started the de-encapsulation process. In which order does thede-encapsulation process occur? 1) remove IP header 2) remove Ethernet header and trailer 3) remove TCP header 4) pass data to the application 1) add TCP header to data 2) add an IP header 3) add frame header and trailer 4) encode the frame into bits 1) remove Ethernet header and trailer 2) remove IP header
3) remove TCP header 4) pass data to the application 1) add TCP header to data 2) add Ethernet header and trailer 3) add an IP header 4) encode the frame into bitsQ.21 What is an advantage of the use of layers in the OSI reference model? It breaks network communications into larger parts. It increases complexity. It prevents changes in one layer from affecting other layers. It requires the use of single-vendor equipment for hardware and software communications.Q.22 What is the correct order of the layers of the OSI reference model, starting at the lowest layer andworking up the model? data link, physical, transport, network, presentation, session, application physical, data link, network, session, transport, presentation, application physical, data link, network, transport, presentation, session, application physical, data link, network, transport, session, presentation, application application, session, presentation, transport, data link, network, physical
