Client-server model

In Question 11, suppose one computer is upgraded from Windows 7 Professional to Windows Server 2012 R2. Which networking model can the network now support that it could not support without the upgrade?

Star-bus topology

In Question 14, 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?

UDP, because guaranteed delivery is not as important as fast transmissions.

Is TCP or UDP normally used when streaming live video? Why?

Conversational voice, streaming live audio and video, and streaming stored audio and video

List three types of services a network might support that are considered part of unified communications or convergence.

Server Infrastructure, Desktop Infrastructure, Private Cloud, Data Platform, Business Intelligence, Messaging, Communication, and SharePoint

A frame

What is a PDU called at the Link layer?

Answer: Segment Answer: Datagram Answer: Transport layer

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?

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

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

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

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

Port number

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

In case you need to ship the switch in the future.

Why does Cisco recommend you keep the shipping container?

To protect the server against static electricity, or ESD

Why is it important to wear an ESD strap when installing a server in a rack?
