Network-Pro Chapter 1

Which two of the following are included as part of Data Link layer specifications?

Identifying physical network devices. Controlling how messages are propagated through the network.

Which of the following are functions of the MAC sublayer? (Select two.)

Defining a unique hardware address for each device on the network Letting devices on the network have access to the LAN

Which of the following tasks is associated with the Session layer?

Connection establishment

Which of the following geographic network types are typically managed by a city as a public utility?

Metropolitan Area Network (MAN)

In the OSI model, which of the following functions are performed at the Presentation layer? (Select two.)

Specify data format (such as file formats) Encrypt and compress data

A switch is associated with which OSI model layer?

Data Link

You have implemented a network where hosts are assigned specific roles, such as for file sharing and printing. Other hosts access those resources but do not host services of their own.

Client-server

Match each decimal value on the left with the corresponding hexadecimal value on the right. Not all decimal values have a corresponding hexadecimal value.

11->17 B->11 D->13 F->15 C->12 10->16

Which of the following topologies connects each device to a neighboring device?

Ring

At which of the following OSI layers does a router operate?

Layer 2

You want to implement a fault tolerant topology as you interconnect routers on your wide area network. Which of the following would meet your needs?

Mesh

You are an application developer and are writing a program to exchange video files through a TCP/IP network. You need to select a transport protocol that will guarantee delivery.
Which TCP/IP protocol would you implement that provides this capability?

TCP

Which of the following functions are performed at the Physical layer of the OSI model?

Movement of data across network cables

You have implemented a network where each device provides shared files with all other devices on the network.
What type of network do you have?

Peer-to-peer

In the OSI model, which of the following functions are performed at the Application layer? (Select all that apply.)

Integration of network functionality into the host operating system Enabling communication between network clients and services

The Data Link Layer of the OSI model is comprised of two sublayers. What are they? (Select two.)

MAC LLC

Which OSI model layer is responsible for guaranteeing reliable message delivery?

Transport

Your company has just acquired another company in the same city. You are given the task of integrating the two e-mail systems so that messages can be exchanged between the e-mail servers. However, each network uses an e-mail package from a different vendor.
Which TCP/IP protocol will enable messages to be exchanged between systems?

SMTP

In which of the following topologies does each device on the network act as a repeater, sending the signal to the next device?

Ring

Which of the following topologies connects all devices to a trunk cable?

Bus

You have been asked to implement a network infrastructure that will accommodate failed connections.
Which of the following network topologies provides redundancy for a failed link?

Mesh

Which of the following protocols stores email on the mail server and allows users to access it from various client devices without having to download it?

IMAP4

What protocol sends e-mail to a mail server?

SMTP

At which layer of the OSI model do hubs operate?

Physical

Match the networking function or device on the left with the OSI model layer it is associated with on the right.

Application: HTTP Presentation: ASCII Session : Session ID number Transport : Port numbers Network : Router Data Link : Switch Physical: Wireless access point

Which of the following topologies connects each network device to a central hub?

Star

During TCP/IP communications between two network hosts, information is encapsulated on the sending host and decapsulated on the receiving host using the OSI model.
Match the information format on the left with the appropriate layer of the OSI model on the right. (Not all layers have a matching information format.)

Session Layer ->(leave blank) Transport Layer Segments Network Layer Packets Data Link Layer Frames Physical Layer Bits

Which of the following devices operates at the OSI model layer 2?

Switch

Match each layer of the TCP/IP model on the left with the corresponding layer of the OSI model on the right. Each option on the left can be used more than once.

Presentation-> Application Data Link-> Network access Application-> Application Session-> Application Network-> Internet Transport-> Transport

What is the decimal format of the following binary IP address?

206.58.170.67

What device is used to create a physical star topology?

Switch

What is the binary format for the following decimal IP address?
131.9.202.111

10000011.00001001.11001010.01101111

Which protocol is used on the World Wide Web to transmit Web pages to Web browsers?

HTTP

Your company purchases a new bridge, which filters packets based on the MAC address of the destination computer. On which layer of the OSI model is this device functioning?

Data Link

Which of the following devices operates at the OSI model layer 1?

Hub

At what OSI layer does a router operate to forward network messages?

Network

Which of the following protocols includes extensive error checking to ensure that a transmission is sent and received without mistakes?

TCP

In the OSI model, what is the primary function of the Network layer?

Routes messages between networks

You have implemented an ad-hoc wireless network that doesn’t employ a wireless access point. Every wireless network card can communicate directly with any other wireless network card on the network.

What type of physical

network topology has been implemented in this type of network?

Mesh
