5AB-INT-Chapter 3

What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

• encapsulation

• flow control

• access method

• response timeout

What type of communication will send a message to all devices on a local area network?

• broadcast

• multicast

• unicast

• allcast

What process is used to place one message inside another message for transfer from the source to the destination?

• access control

• decoding

• encapsulation

• flow control

A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?

• HTTP, IP, TCP, Ethernet

• HTTP, TCP, IP, Ethernet

• Ethernet, TCP, IP, HTTP

• Ethernet, IP, TCP, HTTP

Which statement is correct about network protocols?

• Network protocols define the type of hardware that is used and how it is mounted in racks.

• They define how messages are exchanged between the source and the destination.

• They all function in the network access layer of TCP/IP.

• They are only required for exchange of messages between devices on remote networks.

Which statement is true about the TCP/IP and OSI models?

• The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.​

• The TCP/IP network access layer has similar functions to the OSI network layer.​

• The OSI Layer 7 and the TCP/IP application layer provide identical functions.

• The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.​

What is an advantage of using standards to develop and implement protocols?

• A particular protocol can only be implemented by one manufacturer.

• Products from different manufacturers can interoperate successfully.

• Different manufacturers are free to apply different requirements when implementing a protocol.

• Standards provide flexibility for manufacturers to create devices that comply with unique requirements.

What three application layer protocols are part of the TCP/IP protocol suite?

• ARP

• DHCP

• NAT

• PPP

What are proprietary protocols?

• protocols developed by private organizations to operate on any vendor hardware

• protocols that can be freely used by any organization or vendor

• protocols developed by organizations who have control over their definition and operation

• a collection of protocols known as the TCP/IP protocol suite

Which device performs the function of determining the path that messages should take through internetworks?

• a firewall

• a web server

• a DSL modem

• Router
