networking chapter 3 exam study
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 will happen if the default gateway address is incorrectly configured on a host?
The host cannot communicate with hosts in other networks.
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
the process of determining when to begin sending messages on a network
blank (none)
the process of unpacking one message format from another message format
blank (none)
What type of communication will send a message to all devices on a local area network?
broadcast
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
Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
network access protocol
preparing packets to be transmitted over the network media
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
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 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.
What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
DHCP DNS FTP
What is an advantage of using standards to develop and implement protocols?
Products from different manufacturers can interoperate successfully.
Which statement is correct about network protocols?
They define how messages are exchanged between the source and the destination.
IANA
This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers
ISO
This organization is the largest developer of international standards in the world of a wide variety of products and services. It is known for its Open Systems Interconnection (OSI) reference model.
ISOC
This organization promotes the open development, evolution, and use of the Internet throughout the world.
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
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
application protocol
governing the way a web server and a web client interact
transport protocol
managing the individual conversations between web servers and web clients
the process of placing one message format inside another message format
message encapsulation
the process of converting information from one format into another acceptable for transmission
message encoding
the process of breaking up a long message into individual pieces before being sent over the network
message sizing
At which layer of the OSI model would a logical address be encapsulated?
network layer
EIA
none
network time protocol
none
internet protocol
talking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses
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
