IMAP

POP

HTTPS

SMTP

 

2. Which application layer protocol uses message types such as GET, PUT, and POST?

DHCP

DNS

POP3

SMTP

HTTP

 

3. Two students are working on a network design project. One student is doing the drawing, while the other student is writing the proposal. The drawing is finished and the student wants to share the folder that contains the drawing so that the other student can access the file and copy it to a USB drive. Which networking model is being used?

client-based

master-slave

peer-to-peer

point-to-point

 

4. Fill in the blank.

The HTTP message type used by the client to request data from the web server is the _GET_ message.

 

5. What part of the URL, http://www.cisco.com/index.html, represents the top-level DNS domain?

www

.com

index

http

 

6. Which two definitions accurately describe the associated application layer protocol? (Choose two.)

HTTP – enables devices on a network to obtain IP addresses

Telnet – provides remote access to servers and networking devices

DNS – resolves Internet names to IP addresses

SMTP – transfers web pages from web servers to clients

FTP – transfers email messages and attachments

 

7. Match the function to the name of the application. (Not all options are used.)

Place the options in the following order:

DHCP -> dynamically assigns IP address to clients

DNS -> maps URLs to numerical addresses

IMAP -> allows viewing of messages on email clients

HTTP -> displays web pages

SMTP -> sends email messages

 

8. The application layer of the TCP/IP model performs the functions of what three layers of the OSI model? (Choose three.)

session

presentation

physical

data link

transport

network

application

 

9. What do the client/server and peer-to-peer network models have in common?

Both models have dedicated servers.

Both models require the use of TCP/IP-based protocols.

Both models support devices in server and client roles.

Both models are used only in the wired network environment.

 

10. Which layer in the TCP/IP model is used for formatting, compressing, and encrypting data?

internetwork

session

application

network access

presentation

 

11. What is true about the Server Message Block protocol?

Different SMB message types have a different format.

Clients establish a long term connection to servers.

SMB messages cannot authenticate a session.

SMB uses the FTP protocol for communication.

 

12. Fill in the blank.

Refer to the exhibit. What command was used to resolve a given host name by querying the name servers?

NSLOOKUP

 

13. What is an advantage for small organizations of adopting IMAP instead of POP?

When the user connects to a POP server, copies of the messages are kept in the mail server for a short time, but IMAP keeps them for a long time.

POP only allows the client to store messages in a centralized way, while IMAP allows distributed storage.

Messages are kept in the mail servers until they are manually deleted from the email client.

IMAP sends and retrieves email, but POP only retrieves email.

 

14. Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

PC_3

PC_2

PC_1 and PC_3

PC_1

 

15. Which phrase describes an FTP daemon?

a program that is running on an FTP server

an application that is used to request data from an FTP server

a diagnostic FTP program

a program that is running on an FTP client

 

16. Which two tasks can be performed by a local DNS server? (Choose two.)

providing IP addresses to local hosts

allowing data transfer between two network devices

mapping name-to-IP addresses for internal hosts

forwarding name resolution requests between servers

retrieving email messages

 

17. Which three statements describe a DHCP Discover message? (Choose three.)

The source MAC address is 48 ones (FF-FF-FF-FF-FF-FF).

All hosts receive the message, but only a DHCP server replies.

The message comes from a client seeking an IP address.

The message comes from a server offering an IP address.

The destination IP address is 255.255.255.255.

Only the DHCP server receives the message.

 

18. Fill in the blank.

What is the acronym for the protocol that is used when securely communicating with a web server?

HTTPS

 

19. Which statement is true about FTP?

The client can choose if FTP is going to establish one or two connections with the server.

The client can download data from or upload data to the server.

FTP is a peer-to-peer application.

FTP does not provide reliability during data transmission.

 

20. Match a statement to the related network model. (Not all options are used.)

peer-to-peer network

[+] no dedicated server is required

[+] client and server roles are set on a per request basis

 

peer-to-peer aplication

[#] requires a specific user interface

[#] a background service is required

 

21. A manufacturing company subscribes to certain hosted services from its ISP. The services that are required include hosted world wide web, file transfer, and e-mail. Which protocols represent these three key applications? (Choose three.)

SNMP

23. What is an example of network communication that uses the client-server model?

A user uses eMule to download a file that is shared by a friend after the file location is determined.

A workstation initiates an ARP to find the MAC address of a receiving host.

A workstation initiates a DNS request when the user types www.cisco.com in the address bar of a web browser.

A user prints a document by using a printer that is attached to a workstation of a coworker.

 

24. What are two characteristics of the application layer of the TCP/IP model? (Choose two.)

the establishing of window size

responsibility for physical addressing

the creation and maintenance of dialogue between source and destination applications

responsibility for logical addressing

closest to the end user
