OSI Model & TCP/IP Model

What are the two primary models used when discussing network functionality?

• OSI model

• OIS model

• TCP/UDP model

• TCP/IP model

What layer of the OSI model describes methods for exchanging data frames between devices over a common media?

• Application

• Data Link

• Physical

• Session

What layer of the OSI model provides common representation of the data transferred between Application layer services?

• Application

• Data Link

• Presentation

• Session

What layer of the OSI model contains protocols used for process-to-process communication?

• Application

• Presentation

• Transport

• Data Link

What are the four layers of the TCP/IP model?

• Application, Presentation, Session, and Transport

• Application, Network, Data Link, and Physical

• Application, Transport, Internet, and Network Access

• Application, Transport, Network, and Physical

What layer of the TCP/IP model controls the hardware devices and media that makeup the network?

• Application

• Network Access

• Physical

• Transport

What layer of the TCP/IP model determines the best path through the network?

• Network Access

• Application

• Network

• Internet

The OSI Layer 3, the network layer, maps directly to what TCP/IP layer?

• Application

• Internet

• Network Access

• Transport

The TCP/IP application layer includes a number of protocols that provide specific functionality to a variety of end user applications. What is an example of an Application layer protocol?

• FTP

• TCP

• IPv4

• Ethernet

As data moves through the network, it is broken down into smaller pieces and identified so that the pieces can be put back together when they arrive at the destination. Each piece is assigned a specific name (protocol data unit [PDU]) and associated with a specific layer of the TCP/IP and OSI models. What PDU is formed at the Application layer of the OSI model?

• Segment

• Data

• Frame

• Bit
