In NDP Neighbor Solicitation does the following task: A) 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.

C) are used by nodes to respond to a Neighbor Solicitation message. D) inquire with Router Solicitation messages to locate routers on an attached link.Routers which forward packets not addressed to them generate Router Advertisements immediately upon receipt of this message rather than at their next scheduled time.

D

DNS is normally responsible for translating IP address to host names. T/F?

F

Digital transmission produces more errors than analog transmission. T/F?

F

Each network interface on your computer is identified by a series of letters known as a MAC address. T/F?

F

IPv6 uses 32-bit addresses as opposed to the 128-bit addresses used by IPv4 allowing for a substantially larger number of possible addresses. T/F?

F

In TCP/IP, the parts of the IP address that are used as the network and host addresses are fixed, so the network and host addresses can be determined without more information. T/F?

F

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

F

Polling is the process of permitting all clients to transmit or receive at any time. T/F?

F

Star ring topology can be used to connect wireless devices. T/F?

F

The Internet's Transmission Control Protocol (TCP) uses the MTU to determine the minimum size of each packet in any transmission. T/F?

F

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. T/F?

F

Using HTTP version 1.0, a keep-alive tells the server "please keep this connection open, I'll request more." T/F?

F

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

F

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

T

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

T

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. T/F?

T

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. T/F?

T

DHCP dynamically assigns an IP address to a computer. T/F?

T

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

T

In the OSI model, the application layer provides a set of utilities for applications and is the end user's access to the network. T/F?

T

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

T

TCP includes a sequence number so that the packets can be reassembled at the destination in the correct order. T/F?

T

The data link layer accepts messages from the network layer and controls the hardware that transmits them. T/F?
