The TCP/IP model Application layer
Uses packet sequencing and application mapping through port numbers
Represents data to the user plus encoding and dialog control
Controls the hardware devices and media make up of the network
Determines the best path through the network
The TCP/IP model Internet layer
Uses packet sequencing and application mapping through port numbers
Represents data to the user plus encoding and dialog control
controls the hardware devices and media make up of the network
Determines the best path through the network
The TCP/IP model Network Access layer
Uses packet sequencing and application mapping through port numbers
Represents data to the user plus encoding and dialog control
controls the hardware devices and media make up of the network
Determines the best path through the network
The TCP/IP model Transport layer
Uses packet sequencing and application mapping through port numbers
Represents data to the user plus encoding and dialog control
controls the hardware devices and media make up of the network
Determines the best path through the network
When a server responds to a web request, what occurs next in the encapsulation
process after the web page data is formatted and separated into TCP segments?
The client decapsulates the segment and opens the web page.
The client adds the appropriate physical address to the segments so that the server
can forward the data.
The server converts the data to bits for transport across the medium.
The server adds the source and destination IP address to each segment header to
deliver the packets to the destination.
The server adds the source and destination physical addresses to the packet header.
Which layer of the OSI model is concerned with end-to-end message delivery across the network?
Network
Transport
Data link
Application
Which layers of the OSI model are combined into Network Access layer of the TCP/IP model?
(Choose all that apply.)
Network
Presentation
Data Link
Application
Physical
Which layers of the OSI model are combined into the Application layer of the TCP/IP model?
(Choose all that apply.)
Network
Presentation
Application
Session
Transport
Which of the following are true about LANs and WANS? (Choose two.)
LANs connect groups of networks using ISPs.
LANs consist of hosts communicating with logical addresses.
WANS connect groups of networks using TSPs
WANS connect LANs
Hosts on a LAN use physical addressing to communicate.
Which of the following is associated with the OSI Network Layer (Layer 3)?
IP address
Frames
MAC address
Physical addressing
Which of the following is NOT a benefit of a layered model to describe network protocols
Prevents technology or capability changes in one layer from affecting other layers above and below
Provides a common language to describe networking functions and capabilities
Simplifies protocol design, because protocols that operate at a specific layer
have defined information that they act upon and a defined interface to the layers above and below
Prevents development of new products with use of new technologies as the model is technology dependent
Which of the following is the correct "top down" order of the OSI model?
Application, presentation, session, network, transport, data link, physical
Application, presentation, session, transport, network, data link, physical
Application, session, presentation, transport, network, data link, physical
Application, presentation, session, network, data link, transport, physical
Which of the following is the process for interweaving multiple data packets on a shared communication channel or network medium?
Multicasting
Multiplexing
Encapsulation
Multidirecting
Which of the following terms defines dividing data streams into smaller pieces suitable
for transmission?
Protocol
Multiplexing
Segmentation
Encapsulation
Which one of the following is associated with Transport Layer (Layer 4) of the OSI model?
JP
TCP
FTP
HTTP
Which OSI layer contains protocols with methods for exchanging data frames between devices over a common media?
Network
Physical
Transport
Data link
Which term describes a specific set of rules that determine the formatting
and the process of encapsulation used to forward data?
Segmentation
Protocol
Multiplexing
QoS
Reassembly
Which OSI layer is associated with IP addressing?
Network
Presentation
Transport
Data link
Which type of addressing is found at the OSI Layer 2 (Data Link)? (Choose two.)
Logical
Physical
MAC
IP
Port
A device that moves data between networks is called a (a)
A limited-use protocol owned by a company is considered to be (a)
The device that connects a workstation or server to the media is called a/an (a) card.
The elements of communication include a message source, a message destination, and
a (a) , or medium, to transport the message.
