1	What type of server would use IMAP? DNS DHCP e-mail FTP Telnet web

2	A network client in a corporate environment reboots. Which type of server would most likely be used first? DNS DHCP e-mail FTP Telnet web

3	Which protocol is used by FTP to transfer files over the Internet? TCP SMTP UDP SNMP

4	Which protocols are TCP/IP application layer protocols? (Choose two.) UDP FTP IP SMTP TCP

5	Which of the following are layers of the TCP/IP model? (Choose three.) Application Physical Internet Network Access Presentation

6

You are creating a network-based video game. What influences your decision about which transport protocol 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.

7	Whenever e-mail clients send letters, what device is used to translate the domain names into their associated IP addresses? Uniform Resource Locator Network redirector server SNMP server DNS server

8	A network administrator needs to allow web pages on the company web server to be accessed securely. What port number is used to request web content to be transmitted using a secure protocol? 53 69 80 443

9	Which port number is used by SMTP? 20 21 25 26 110

10	Which protocol is used by e-mail servers to communicate with each other? FTP HTTP TFTP SMTP POP SNMP

11	A computer user encounters an issue when printing a document. Which application could a computer user use to contact technical support to gain an immediate answer to an issue? blog e-mail web mail instant messaging virtual reality virtualization

12

An Internet server is running both FTP and HTTP services. How does the server know which of these 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.

13	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 layering

14	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 addresses

15	Cabling issues are associated with which OSI layer? 4 2 1 3

16	A device receives an Ethernet frame and recognizes the MAC address as its own. What does the device 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 trailer

17

A client has decoded a frame and started the de-encapsulation process. In which order does the de-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 bits

18	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.

19

What is the correct order of the layers of the OSI reference model, starting at the lowest layer and working 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

20	What three items are contained in an Ethernet header and trailer? (Choose three.) source IP address source MAC address destination IP address destination MAC address error-checking information
