HTTP | ||
FTP | ||
Telnet | ||
2. What are two forms of application layer software? (Choose two.) | ||
applications | ||
dialogs | ||
requests | ||
services | ||

3. 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 | ||
4. 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 during a query | ||
passes authentication information between the server and client | ||
5. What is the automated service that matches resource names with the required IP address? | ||
HTTP | ||
SSH | ||
FQDN | ||
DNS | ||
Telnet | ||
SMTP | ||
6. What three protocols operate at the Application layer of the OSI model? (Choose three.) | ||
ARP | ||
DNS | ||
PPP | ||
SMTP | ||
POP | ||
ICMP | ||
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 | ||
delivers email to clients via the POP3 protocol | ||
12. Which two protocols are used to control the transfer of web resources from a web server to a client browser? (Choose two.) | ||
ASP | ||
FTP | ||
HTML | ||
HTTP | ||
HTTPS | ||
IP | ||
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 | ||
application | ||
transport | ||
15. Refer to the exhibit. What is the destination port for the communication that is represented on line 5? | ||
80 | ||
1261 | ||
15533 | ||
3912 | ||
65520 | ||
16. What are two characteristics of peer-to-peer networks? (Choose two.) | ||
scalable | ||
one way data flow | ||
decentralized resources | ||
centralized user accounts | ||
resource sharing without a dedicated server | ||
17. What application layer protocol describes the services that are used for file sharing in Microsoft networks? | ||
DHCP | ||
DNS | ||
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 | ||
