​Network

At what layer of the OSI model do the IP, ICMP, and ARP protocols operate?​

​Layer 7

HTTP, IMAP4, FTP, and Telnet are all examples of protocols that operate at what layer of the OSI model?​

fragmentation

If a Network layer protocol is aware that a packet is larger than the maximum size for its network, it will divide the packet into smaller packets in a process known as:​

HTTP (Hyper Text Transfer Protocol)

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

​bus topology

In what network topology are devices daisy-chained together in a single line?​

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

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

​Presentation

Select the layer of the OSI model that is responsible for reformatting, compressing, and/or encrypting data in a way that the application on the receiving end can read:​

demarc

The device where a telecommunications service provider network ends and an organization's network begins is referred to as what option below?​

encapsulation

The process of adding a header to the data inherited from the layer above is called what option below?​

Material Safety Data Sheet (MSDS)

The proper handling procedures for substances such as chemical solvents is typically outlined in which of the following options?

Transport layer

The segment or datagram protocol data unit exists at what layer of the OSI model?​

​multicast distribution

What is the name for a client-server model with one server and many clients, such as when an application is used to watch a live sports event?​

​frame

What is the name for the protocol data unit (PDU) ​of the Data Link layer?

Session Layer

What layer of the OSI model describes how data between applications is synced and recovered if messages don't arrive intact at the receiving application?​

SMTP

What mail protocol is used to send mail messages to a server?​

Remote Desktop Services

What service provided by Windows Server 2012 R2 allows a computer to serve up applications to other computers on the network?

​global account

When using a Windows domain, what is the domain-level account for each user known as?​

RTP (Real time transport protocol)

Which Session layer protocol is a streaming live video teleconference likely to use on the network? UDP

Remote Desktop

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

Telnet

Which client-server application allows an administrator to control a remote computer, but does not encrypt or secure the communication between client and server?

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?

They centralize user account logins ​

Which of the following is not one of the disadvantages of peer-to-peer networks?

SSL and TLS (Secure Sockets Layer & Transport Layer Security)

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

​Layer 2

​A standard network switch operates at what layer of the OSI model?

​fail-close

​An open electrical circuit as a result of a failed circuit breaker is considered to be what type of failure system?

​node

​Any computer or device on a network that can be addressed on the local network is referred to as a:

​convergence

​Using the same network to deliver multiple types of communications services, such as video, voice, and fax, is known as:

​star topology

​What physical network topology consists of all connected devices connecting to one central device, such as a switch?
