what message type is used by a client to communicate securely with a web server

GET

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?

IMAP

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?

IMAP and FTP

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

Mapping name-to-IP addresses for internal hosts; forwarding name resolution requests between servers.

peer-to-peer network

PC_2

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?

Peer-to-peer

which application layer protocol is used to provide file-sharing and print services to Microsoft applications

Which two definitions accurately describe the associated application layer protocol?

Telnet and HTTP

which statement is true about FTP?

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

what is an example of network communication that uses the client-server model

a workstation initiates an ARP to find mac address of a receiving host.

IMAP

allows viewing of messages on email clients

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

both models are used only in the wired network environment

Peer-to-peer applications

requires a specific user interface; a background service is required.

What are two characteristics of the application layer of the TCP/IP model?

the creation and maintenance of dialogue between source and destination applications, and closest to the end user

what is the function of the Nslookup utility
