What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)

DHCP * DNS * FTP*

. A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?

HTTP, TCP, IP, Ethernet

Match the description to the organization.

ISOC -> The organization promotes the open development, evolution, and use of the internet throughout the world ISO -> This organization is the largest developer of international standars in the world for a wide variety of products and services. It is know for its Open System Interconection (OSI) reference model. IANA -> This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers

Match each description to its corresponding term. (Not all options are used.)

Place the options in the following order: - not scored - message encoding -> the process of converting information from one format into another acceptable for transmission message encapsulation -> the process of placing one message format inside another message format - not scored - message sizing -> the process of breaking up a long message into individual pieces before being sent over the network

Which statement is true about the TCP/IP and OSI models?

The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.

What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with hosts in other networks.*

Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)

application * presentation * session*

Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?

application, transport, Internet, and network access layers*

What type of communication will send a message to all devices on a local area network?

broadcast

Which address does a NIC use when deciding whether to accept a frame?

destination MAC address

What process is used to place one message inside another message for transfer from the source to the destination?

encapsulation

What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

flow control*

What is a benefit of using a layered model for network communications?

fostering competition among device and software vendors by enforcing the compatibility of their products*

Which PDU format is used when bits are received from the network medium by the NIC of a host?

frame

What is the general term that is used to describe a piece of data at any layer of a networking model?

protocol data unit*

What are proprietary protocols?

protocols developed by organizations who have control over their definition and operation

Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?

segment

At which layer of the OSI model would a logical address be encapsulated?

network layer

Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

802.11*

What is an advantage of network devices using open standard protocols?

A client host and a server running different operating systems can successfully exchange data.*

Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process? (Choose two.)

A frame with the destination MAC address of RouterA. * A packet with the destination IP address of ServerB.*

Match the protocol function to the description while taking into consideration that a network client is visiting a web site. (Not all options are used.)

Place the options in the following order: governing the way a web server and a web client interact -> application protocol taking the segments from transport protocol, encapsulating them into packets, and assigning them with appropriate addresses -> internet protocol preparing packets to be transmitted over the network media -> network access protocol - not scored - managing the individual conversations between web servers and web clients -> transport protocol

What is an advantage of using standards to develop and implement protocols?

Products from different manufacturers can interoperate successfully.*

A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client?

TCP

Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?

TCP

Which statement is correct about network protocols?

They define how messages are exchanged between the source and the destination.*

A computer in a given network is communicating with a specific group of computers. What type of communication is this?

multicast

Which characteristic describes the default gateway of a host computer?

the logical address of the router interface on the same network as the host computer*

What is a function of Layer 4 of the OSI model?

to describe the ordered and reliable delivery of data between source and destination
