Cisco first semester Chapter II answers

001 What is the role of the TCP/IP network access layer?

Path determination and Packet switching

Data representation, coding, and control

Reliability, flow control and error detection

Specify the components that make up the physical link and how to access it

Dividing data segments into packets

002 Which of the following statements correctly indicate the role of intermediate devices in the network? (select three items)

Determining the data transfer path

Initiating data communication

re-timing and retransmission of data signals

Send data stream

Managing Data Flow

Final end point of the data stream

003 Which of the following three statements is the most accurate description of the local area network (LAN)? (select three items)

LAN typically located within a region.

Such networks are managed by an organization.

Different network segments in a LAN are generally connected by renting a connection.

Security and access control for such networks is controlled by the service provider.

LAN provide network services and application access for users in the same organization.

Each terminal of such a network is usually connected to a telecommunications service provider (TSP).

004 What is a PDU?

Frame corruption during transmission

Data reorganized on the destination device

Packets retransmitted due to loss of communication

encapsulation of specific layers

005 OSI model which two layers of functionality are the same as the TCP/IP model's network access layer? (select two items)

Network layer

Transport Layer

Physical Layer

Data Link Layer

Session Layer

006 See illustration. Which type of network is shown?

WAN

Mans

LAN

Wlan

007 which of the following features correctly represents the terminal equipment in the network?

008 What is the main function of the 4-tier port designation?

Identify devices on your local media

Identifies the number of hops between the source device and the destination device

Identify the best path through the network to the intermediary device

Identify the source and destination terminal devices being communicated

identifies the process or service that is communicating within the terminal device

009 See illustration. Which of the following sets of devices contains only terminal equipment?

A, C, D

B, E, G, H

C, D, G, H, I, J

specify how protocol layer functions are implemented

Overview of the features required for communication between tiers and tiers

Limited hardware compatibility

needs to be dependent on the protocol layer's encapsulation process

Eliminate the standardization between manufacturers

Help with intermediate devices for processing and path selection

013 What kind of equipment is considered an intermediate device?

File server

IP Phone

Notebook PC

Printer

Switch

014 See illustration. Which network term describes the data interchange process shown in the figure?

Channel

Pdu

Circulating and losing

Multiplexing

Packaging

015 What does the data link layer do during the encapsulation process?

Address is not added.

Physical Layer

Data Link Layer

Network Layer

Transport Layer

What are the key features of the 017 package? (select three items)

To modify the original data before transmission

identity data fragments belong to the same communication

Provides a unified network path for communications

ensure that data fragments can be forwarded to the correct receiving end device

Implementing a full message reorganization

Tracking the delay between terminal devices

018 what can be determined by examining the network layer header?

Destination devices on the local media

the path used to reach the destination host

Bits to be transferred through the media

The source application or process that created the data
