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

802.11

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

<-- Empty --> 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. <-- empty --> message sizing -> the process of breaking up a long message into individual pieces before being sent over the network.

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

What three application layer protocols are part of the TCP/IP protocol suite?

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

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

Products from different manufacturers can interoperate successfully

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

Segments are sent from the transport layer to the internet layer.

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 beween server and client?

TCP

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

application, presentation, and session

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

Which address provides a unique host address for data communications at the internet layer?

logical address

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

multicast

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

network layer

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

segment

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

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

Which statement is true about the TCP/IP and OSI models? 1. The TCP/IP transport layer and the OSI Layer 4 provide similar services and functions. 2. The TCP/IP network access layer has similar functions to the OSI network layer 3. The OSI layer 7 and the TCP/IP application layer provide identical functions. 4. The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.

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

Which statement is correct about network protocols? 1. Network protocols define the type of hardware that is used and how it is mounted on racks 2. They define how messages are exchanged between the source and the destination. 3. They all function in the network access layer of TCP/IP 4. They are only required for exchange of messages between devices on remote networks.

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

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.

Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?

ARP

What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the MAC address of any host on the local network

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.

Match the description to the organization

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

A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

The MAC address of the default gateway

If the default gateway is configured incorrectly on the host, what is the impact on communications?

The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.

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

The host cannot communicate with hosts in other networks.

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

encapsulation

What method can be used by two computer 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 devices 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

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.)

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 blank --> managing the individual conversations between web servers and web clients -> transport protocol

At which layer of the OSI model would a logical address be added during encapsulation?

network layer.

Which command is used to remove only VLAN 20 from the switch?

no vlan 20

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 characteristic describes the default gateway of a host computer?

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