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

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?
1) Closest to the end user. 2) The creation and maintenance of dialogue between source and destination applications.
What are two characteristics of the application layer of the TCP/IP model? (Choose two.)
Both models support devices in server and client roles.
What do the client/server and peer-to-peer network models have in common?
The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files between a client and server on a computer network. FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server.
What is FTP?
Gnutella
What is a common protocol that is used with peer-to-peer applications such as WireShare, Bearshare, and Shareaza?
Messages are kept in the mail servers until they are manually deleted from the email client.
What is an advantage for small organizations of adopting IMAP instead of POP?
SMB clients can establish a long-term connection to the server.
What is an advantage of SMB over FTP?
A workstation initiates a DNS request when the user types www.cisco.com in the address bar of a web browser.
What is an example of network communication that uses the client-server model?
HTTPS
What is the acronym for the protocol that is used when securely communicating with a web server?
The network includes a dedicated server.
What is true about a client-server network?
Clients establish a long term connection to servers.
What is true about the Server Message Block protocol?
.com
What part of the URL, http://www.cisco.com/index.html, represents the top-level DNS domain?
the domain name mapped to mail exchange servers
What type of information is contained in a DNS MX record?
IMAP
When retrieving email messages, which protocol allows for easy, centralized storage and backup of emails that would be desirable for a small- to medium-sized business?
application
Which TCP/IP model layer is closest to the end user?
SMB
Which application layer protocol is used to provide file-sharing and print services to Microsoft applications?
HTTP
Which application layer protocol uses message types such as GET, PUT, and POST?
nslookup
Which command is used to manually query a DNS server to resolve a specific host name?
application layer
Which layer in the TCP/IP model is used for formatting, compressing, and encrypting data?
a program that is running on an FTP server.
Which phrase describes an FTP daemon?
POP3
Which protocol can be used to transfer messages from an email server to an email client?
1) Session Layer 2) Application Layer 3) Presentation Layer
Which three layers of the OSI model provide similar network services to those provided by the application layer of the TCP/IP model? (Choose three.)
1) HTTP 2) MPEG 3) GIF
Which three protocols or standards are used at the application layer of the TCP/IP model? (Choose three.)
1) All hosts receive the message, but only a DHCP server replies. 2) The message comes from a client seeking an IP address. 3) The destination IP address is 255.255.255.255.
Which three statements describe a DHCP Discover message? (Choose three.)
1) DNS - resolves internet names to IP addresses. 2) Telnet - provides remote access to servers and networking devices.
Which two definitions accurately describe the associated application layer protocol? (Choose two.)
1) Forwarding name resolution requests between servers 2) Mapping name-to-IP addresses for internal hosts
Which two tasks can be performed by a local DNS server? (Choose two.)
It is a more efficient way to manage IP addresses than static address assignment.
Why is DHCP preferred for use on large networks?
