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
lower cost implementation
provides a single point of failure
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
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 compute
A computer that responds to a file sharing request is functioning as a server
How does the application layer on a server usually process multiple client requests 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

Microsoft networks?
DHCP
DNS
SMB
SMTP
Telnet

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

What is the automated service that matches resource names with the required IP
address?
HTTP

Telnet
What is the purpose of resource records in DNS?
temporarily holds resolved entries
used by the server to resolve names
sent by the client during a query
passes authentication information between the server and client
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
What three protocols operate at the Application layer of the OSI model? (Choose
three.)
ARP
DNS
PPP
SMTP
POP
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 email server
SMTP supports file sharing
Telnet provides a virtual connection for remote access
Which email components are used to forward mail between servers? (Choose two.)
MTA
SMTP
MDA
IMAP
POP
Which layer of the OSI model supplies services that allow users to interface with the
network?
physical
session
network
presentation
application
Which statements are correct concerning the role of the MTA in handling email?
(Choose three.)
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
routes email to the MDA on other servers

server to a client browser? (Choose two.)
