7. What are three properties of peer-to-peer applications? (Choose three.)
* acts as both a client and server within the same communication.
*requires centralized account administration.
* hybrid mode includes a centralized directory of files.
* can be used in client-server networks.
*requires a direct physical connection between devices.
*centralized authentication is required.

8. Which application layer protocols correctly match a corresponding function? (Choose two.)
*DNS dynamically allocates IP addresses to hosts
* HTTP transfers data from a web server to a client
*POP delivers email from the client to the server email server
*SMTP supports file sharing
* Telnet provides a virtual connection for remote access

9. Which email components are used to forward mail between servers? (Choose two.)
*MDA
*IMAP
* MTA
*POP
* SMTP
*MUA

10. As compared to SSH, what is the primary disadvantage of telnet?
*not widely available
* does not support encryption
*consumes more network bandwidth
* does not support authentication

11. Which statements are correct concerning the role of the MTA in handling email? (Choose three.)
*routes email to the MDA on other servers
* receives email from the client’s MUA
*receives email via the POP3 protocol
* passes email to the MDA for final delivery
* uses SMTP to route email between servers

13. A small home network has been installed to interconnect three computers together for gaming and file sharing. What two properties represent this network type? (Choose two.)
*User accounts are centralized.
* Security is difficult to enforce.
*Specialized operating system software is required.
*File permissions are controlled by a single computer.
* A computer that responds to a file sharing request is functioning as a server.

14. Which layer of the OSI model supplies services that allow user to interface with the network?
*physical
*session
*network
*presentation

* SMB
*SMTP
*Telnet

18. What are two characteristics of clients in data networks? (Choose two.)
*use daemons
* initiate data exchanges
*are repositories of data
* may upload data to servers
*listen for requests from servers

19. What is the role of the OSI application layer?
*provides segmentation of data
*provides encryption and conversion of data
* provides the interface between the applications on either end of the network
*provides control of all the data flowing between the source and destination devices

20. How does the application layer on a server usually process multiple client request for services?
*ceases all connections to the service
*denies multiple connections to a single daemon
*suspends the current connection to allow the new connection
* uses support from lower layer functions to distinguish between connections to the service
