Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
Segment
HostA attempts to contact ServerB on a remote network. Which two statements describe the addressing that HostA will generate in the process?
A frame with the destination MAC address of RouterA

Application protocol
Governing the way a web server and web client interact
Transport Protocol
Managing the individual conversations between web servers and web clients
Internet Protocol
Taking formatted segments from transport protocol, encapsulating them into packets, assigning them the appropriate addresses, delivering them across the best path to the destination host
Network Access Protocol
Preparing packets to be transmitted over network media
A user sends an HTTP request 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
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
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
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
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
Which protocol is responsible for controlling the size and rate of the HTTP messages exchanged between server and client?
TCP
A computer in a given network is communicating with a specific group of computers. What type of communication is this?
Multicast
What is a function of Layer 4 of the OSI model?
To describe the ordered and reliable delivery of data between source and destination
What is an advantage of network devices using open standard protocols?
A client host and server running different operating systems can successfully exchange data
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 statement describes the function of the Address Resolution Protocol?
ARP is used to discover the MAC address of any host on the local network
At which layer of the OSI model would a logical address be encapsulated?
Network layer
What is the general term that is used to describe a piece of data at any layer of a networking model?
Protocol Data Unit
PDU
Which statement is true about TCP/IP and OSI models?
The TCP/IP Transport layer and OSI Layer 4 provide similar services and functions
Which address provides a unique host address for data communications at the internet layer?
Logical addresses

TCP
Which address does an NIC use when deciding whether to accept a frame?
Destination MAC address
What are proprietary protocols?
Protocols developed by organizations who have control over their definition and operation
Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?
ARP
Address Resolution Protocol
Which command is used to remove only VLAN 20 from a switch?
no vlan 20
