Exam 5: Network and Transport Layers

In its simplest form, the __________ has two columns: the first column lists every destination network, while the second column lists the interface on which that computer should send messages, if they are destined for the network in the first column.

TCP uses _____________ so that the destination station can reassemble the packets into the correct order.

The standard port number for Telnet is 53.

UDP is not commonly used for:

_________created a service that allows organizations to transfer IPv4 addresses they don't need to another organization.

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

When using dynamic routing, routing decisions are always made by a central host or server.

The _____________ is used by a computer to determine how messages will travel through the network.

Source port address is the logical address used to identify the application that is sending the data.

The three fundamental approaches to routing are:

What is a virtual circuit?

TCP/IP is a data link protocol that is used on the Internet.

What are the differences between connectionless and connection-oriented routing? Discuss this in detail. When might UDP be used? TCP? What is a virtual circuit? What is Quality of Service routing and why is it useful?

A routing protocol used inside an autonomous system is called an exterior routing protocol.

A client computer is typically assigned a data link layer address by a:

IP addresses from 224 to 239 belong to Class D and are reserved for

The network layer address for IP is ten bytes long when using IPv4.

Part of the function of address resolution is translating the application layer address of the destination into a network layer address.

The latest version of IP is IPv7, which increases the address space from 128 bits to 256 bits.

The network layer provides guaranteed end-to-end delivery of the message.
