Amsco Chapter 21 Guided Reading Packet Answers

1. At which layer of the OSI model would a logical accost exist encapsulated?

network layer

data link layer

physical layer

ship layer

two. What are proprietary protocols?

protocols developed by private organizations to operate on any vendor hardware

protocols adult past organizations who accept control over their definition and operation

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

protocols that tin be freely used by any organization or vendor

3. Which address does a NIC utilise when deciding whether to have a frame?

Destination IP address

source Ethernet address

source MAC address

source IP address

destination MAC address

4. Match the description to the organization. (Non all options are used.)

ISOC -> The organization promotes the open evolution, development, and utilise of the net throughout the world

ISO -> This organization is the largest developer of international standars in the world for a wide variety of products and services. It is know for its Open System Interconection (OSI) reference model.

IANA -> This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers

5. Lucifer each description to its corresponding term. (Not all options are used.)

message encoding -> the process of converting information from one format into another adequate for transmission

message encapsulation -> the process of placing one message format inside another bulletin format

message sizing -> the process of breaking up a long message into individual pieces before existence sent over the network

6. Which iii layers of the OSI model are comparable in function to the awarding layer of the TCP/IP model? (Cull three.)

data link

presentation

awarding

network

session

concrete

send

7. What procedure is used to identify i bulletin inside some other message for transfer from the source to the destination?

access control

flow command

encapsulation

decoding

eight. Which statement is correct virtually network protocols?

Network protocols define the blazon of hardware that is used and how information technology is mounted in racks.

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

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

They define how messages are exchanged betwixt the source and the destination.

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

Unlike manufacturers are gratis to utilize different requirements when implementing a protocol.

Products from different manufacturers can interoperate successfully.

A detail protocol can but exist implemented by one manufacturer.

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

10. A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct social club of the protocol stack that is used to prepare the asking for manual?

HTTP, TCP, IP, Ethernet

HTTP, IP, TCP, Ethernet

Ethernet, IP, TCP, HTTP

Ethernet, TCP, IP, HTTP

11. Match the protocol role to the clarification while taking into consideration that a network client is visiting a spider web site. (Non all options are used.)

governing the manner a web server and a web client collaborate -> application protocol

talking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses -> net protocol

preparing packets to exist transmitted over the network media -> network access protocol

managing the individual conversation between spider web servers and spider web clients -> transport protocol

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

The TCP/IP network access layer has like functions to the OSI network layer.

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

The OSI Layer vii and the TCP/IP awarding layer provide identical functions.

The TCP/IP transport layer and OSI Layer 4 provide like services and functions.

13. What is an advantage of network devices using open standard protocols?

Internet access can be controlled past a single ISP in each marketplace.

A client host and a server running unlike operating systems can successfully exchange data.

Network communications is bars to information transfers between devices from the same vendor.

Competition and innovation are limited to specific types of products.

14. Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would exist used?

application, ship, Cyberspace, and network admission layers

only awarding, Internet, and network access layers

merely application and Internet layers

only awarding, ship, network, data link, and physical layers

awarding, session, transport, network, data link, and physical layers

only Internet and network access layers

fifteen. Which characteristic describes the default gateway of a host computer?

the logical address assigned to the switch interface connected to the router

the physical address of the router interface on the same network every bit the host computer

the logical accost of the router interface on the same network as the host computer

the physical address of the switch interface continued to the host estimator

16. Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the procedure? (Choose two.)

A packet with the destination IP address of RouterA.

A frame with the destination MAC accost of RouterA.

A packet with the destination IP address of RouterB.

A packet with the destination IP address of ServerB.

A frame with the destination MAC address of ServerB.

A frame with the destination MAC accost of SwitchA.

17. What three application layer protocols are function of the TCP/IP protocol suite? (Choose iii.)

DHCP

FTP

DNS

NAT

PPP

ARP

eighteen. Which PDU format is used when $.25 are received from the network medium past the NIC of a host?

frame

segment

packet

file

19. Which PDU is processed when a host calculator is de-encapsulating a bulletin at the transport layer of the TCP/IP model?

$.25

segment

frame

packet

20. What method can be used past 2 computers to ensure that packets are not dropped considering besides much data is being sent too rapidly?

Admission method

encapsulation

response timeout

flow control

21. What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with other hosts in the local network.

The host cannot communicate with hosts in other networks.

The switch will not forward packets initiated by the host.

A ping from the host to 127.0.0.one would non be successful.

The host will have to use ARP to determine the correct address of the default gateway.

22. What blazon of advice will send a message to all devices on a local expanse network?

Multicast

unicast

allcast

broadcast
