Chapter 1: Introduction to Networking

Remote Desktop

5. Which application embedded in Windows operating systems allows remote control of a computer and uses the RDP secure protocol for transmissions?

What is the fundamental distinction between a MAN and a WAN?

A MAN covers a small geographical area, and WAN covers a large geographical area.

What is the fundamental distinction between a layer 2 switch and a router?

A layer 2 switch belongs only to its local network, and a router belongs to two or more networks.

peer-to-peer

A network consists of five computers, all running Windows 10 Professional. All the computers are connected to a switch, which is connected to a router, which is connected to the internet. Which networking model does the network use?

star

A network consists of seven computers and a network printer, all connected directly to one switch. Which network topology does this network use?

Application layer and Session layer

A user complains that Skype drops her video conference calls and she must reconnect. At which layer of the OSI model should you begin trouble shooting? Which OSI layer is responsible for not dropping the Skype connection?

Application Layer

A user complains that he cannot access a particular website, although he is able to access other websites. At which layer of the OSI model should you begin troubleshooting this problem?

At the Network layer, what type of address is used to identify the receiving host?

IP address

Client/Server

In Question 6, suppose one computer is upgraded from Windows 10 Professional to Windows Server 2016. Which networking model can the network now support that it could not support without the upgrade?

Star-bus

In Question 8, suppose a new switch is connected to the first switch by way of a network cable, and three computers are connected to the new switch. Which network topology is now used?

HTTP

In the client-server model, what is the primary protocol used for communication between a browser and web server?

A computer is unable to access the network. When you check the LED lights near the computer's network port, you discover the lights are not lit. Which layer of the OSI model are you using to troubleshoot this problem? At which two layers does the network adapter work?

Physical Layer & Data Link layer and Physical layer

At the Data LInk layer, which type of network address is used to identify the receiving node?

Physical address, MAC address, hardware address, or Data Link layer address

What is a message called that is delivered by TCP? What is a message called that is delivered by UDP? AT which layer do the two protocols work?

Segment, Datagram, Transport layer

Active Directory

What is the name of the domain controller database that Windows Server 2016 uses to store data about user access and resources on the network?

POP3

Which email protocol allows an email client to download email messages to the local computer?

IMAP4

Which email protocol allows an email client to read mail stored on the mail server?

SSL/TLS

Which two encryption protocols might be used to provide secure transmissions for browser and web server communications?

port address

Which type of address is used at the Transport layer to identify the receiving application?
