network layer

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

no vlan 20

What is network access protocol?

preparing packets to be transmitted over the network media

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

protocol data unit

HostA is attempting to contact Server B. Which two statements correctly describe the addressing that HostA will generate in the process?

A frame with the destination MAC address of Router A. A packet with the destination IP address of Server B.

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.

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

Application, Presentation, Session

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

Frame

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?

HTTP

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.

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

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

TCP

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.

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

Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?

The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk.

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.

Which statement is correct about network protocols?

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

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

logical address

What is transport protocol?

managing the individual conversation between web servers and web clients

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

multicast

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

As part of the encapsulation process at the transport layer, the data stream is divided into more manageable pieces before sending them to the next layer. This process is called...

segmentation

What is internet protocol?

talking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses

the MAC address of the default gateway

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 message sizing?

the process of breaking up a long message into individual pieces before being sent over the network

What is message encoding?

the process of converting information from one format into another acceptable for transmission

What is message encapsulation?

the process of placing one message format inside another message format

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

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