8- 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

- applications
- dialogs
- requests
- services
- syntax
11- 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
12- 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
- delivers email to clients via the POP3 protocol
13- Which layer of the OSI model supplies services that allow user to interface with the network?

15- 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.

18- A network administrator is designing a network for a new branch office of twenty-five users. What are the advantages of using a client-server model? (Choose two.)
- centralized administration
- does not require specialized software
- security is easier to enforce

- provides a single point of failure
19- 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
20- What is the purpose of resource records in DNS?
- temporarily holds resolved entries
- used by the server to resolve names
- sent by the client to the server during a query
- passes authentication information between the server and client
