MIS307: Review ?s

In step 5 of the DHCP process, the server sends a REQUEST (or DHCPREQUEST) packet. letting the client know that it intends to use the address.

False

Internet Message Access Protocol (IMAP) or Post Office Protocol (POP) are protocols used by a client to send messages from a mail server.

False

TCP includes a sequence number to keep track of the total number of packets sent.

False

The Internet's Transmission COntrol Protocol (TCP) uses the MTU to determine the minimum size of each packet in any transmission

False

The application layer is the seventh layer of the internet model and specifies the type of connection and the electrical signals that pass through it

False

The top-level DNS servers delegate to hundreds of thousands of other top-level DNS servers.

False

Using HTTP version 1.0 a keep-alive: tells the server "please keep this connection open, I'll request more"

False

With Post Office Protocol (v3, therefore POP 3) emails remain on the mail server

False

An ARP entry is usually learned and is kept on a device for a certain amount of time, as long as it is being continually used.

True

Because there is a limit on the length of a frame that the data link layer can transmit from node to node, the transport layer breaks up the message from the application layer into several smaller segments.

True

DHCP dynamically assigns an IP address to a computer.

True

For the requests from the Web browser to be understood by the Web server, they must use the same standard protocol or language

True

HTTP response status codes indicate whether a specific HTTP request has been successfully completed.

True

In the OSI model, the application layer provides a set of utilities for applications and is the end user's access to the network

True

The DNS root servers have only one job: to delegate name resolution to other DNS servers.

True

The data link layer accepts messages from the network layer and controls the hardware that transmits them

True

With Client-Based Architecture, application software on the client computers contains presentation, application, and data access logic

True

Polling is the process of permitting all clients to transmit or receive at any time

false

Star-ring topology is most commonly used to implement wireless networks

false

With contention, a computer does not have to wait before it can transmit. A computer can transmit at anytime

false

Each network interface on your computer is identified by a series of letters known as a MAC address

false

HTTPS uses port number

443

A(n) _________ is a specially formatted request used to perform IP address to data link address resolution.

Address Resolution Protocol request

The most widely used LAN protocol is:

Ethernet

A physical circuit refers to the transmission characteristics of the connection, such as the speed at which data is being sent through the connection.

False

DNS is normally responsible for translating IP address to host names.

False

Digital transmission produces more errors than analog transmission

False

IP packets provide guaranteed delivery over the network

False

A destination port number at the transport layer identifies which application on a computer should receive the data transmission.

True

_____is the process of determining the path that a message will travel from sending computer to receiving computer.

Routing

A URL is nothing more than the address of a given unique resource on the Web.

True`

What is the most common type of cabling used in networks?

Twisted Pairs

An endpoint is a

a combination of an IP address and a port number

In a DHCP, how does your computer finally choose an IP address?

a. Sends the request to the DHCP server

In NDP Neighbor Solicitation does the following task;

are used by nodes to determine the link layer address of a neighbor, or to verify that a neighbor is still reachable via a cached link layer address.

When TCP/IP translates a network layer address into a data link layer address, it sends a special ____________ to all computers in the subnet.

broadcast message

The most common error detection method is

cyclical redundancy check

Network Address Translation

enables private IP networks that use unregistered IP addresses to connect to the internet

A protocol data unit (PDU) is a term used in telecommunications that refers to

information added or removed by a layer of the internet model

What do the twists in twisted pair cabling do to improve network communications?

reduces a specific type of interference, called EMI

The fourth layer of the OSI model is called the ____ layer

transport

Radio data transmission requires that each device has a radio receiver/transmitter and uses a specific frequency.

true
