client

presentation
MKV, GIF, and JPG standards are associated with which OSI layer?

2
How many connections are required by FTP between client and server?
a home router
On a home network, which device is most likely to provide dynamic IPv4 addressing to clients on the home network?
application presentation session
These three OSI layers define the same functions as the TCP/IP model application layer.
exchange of information to initiate dialog between peers
This is a function of the OSI session layer.
application
This layer of the OSI model is concerned with the protocols that exchange data between programs running on hosts.
POST
This message type is used when uploading data files to a web server.
SMTP
This protocol is used by a client to send email to a mail server.
HTTP
This protocol is used by a web browser to establish a connection to a web server.
False
True or false? DHCP clients send a DHCP request message to available DHCP servers.
closest to the end user 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.)
GET
What message type is used by an HTTP client to request data from a web server?
.com
What part of the URL, http://www.cisco.com/index.html, represents the top-level DNS domain?
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?
It downloads a copy of email messages leaving the original on the server.
Which is a feature of IMAP?
AAAA
Which of the following DNS record types is used to resolve IPv6 addresses?
NS
Which of the following DNS resource record types resolves authoritative name servers?
Users can share whole files with other users.
Which of the following is a feature of the Gnutella protocol?
the configured default DNS server
Which of the following is displayed by the nslookup utility?
20 21
Which of these ports are used by FTP? (Choose two.)

Which peer-to-peer application allows users to share pieces of many files with each other at the same time?
POP3
Which protocol can be used to transfer messages from an email server to an email client?
HTTPS
Which protocol uses encryption?
The client can download data from or upload data to the server.
Which statement is true about FTP?
HTTP GIF MPEG
Which three protocols or standards are used at the application layer of the TCP/IP model? (Choose three.)
False
True or false? HTTP is a secure protocol
True
True or false? In a peer-to-peer network environment every peer can function as both a client and a server.
False
True or false? Resource sharing over SMB is only supported on Microsoft operating systems.
False
True or false? The peer-to-peer networking model requires the implementation of a dedicated server for data access.
DNS SMTP
Which two are protocols that belong in the OSI application layer?
mapping name-to-IP addresses for internal hosts forwarding name resolution requests between servers
Which two tasks can be performed by a local DNS server? (Choose two.)
It is a more efficient way to manage IPv4 addresses than static address assignment is.
Why is DHCP for IPv4 preferred for use on large networks?
False
True or false? A DNS server that receives a request for a name resolution that is not within its DNS zone will send a failure message to the requesting client.
True
True or false? FTP data transfers take place from client to server (push) and from server to client (pull).
