TCP
Which two components are added to the PDU at the network access layer? (Choose two.)
frame header trailer
What statement describes the function of the Address Resolution Protocol?

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. (Not all options are used.)
IANA: IEEE ISO: EIA ISOC:
Which organization develops the 802 family of standards for wired and wireless LANs and MANs?
IEEE
What organization developed the OSI reference model that is used in networking?
ISO
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
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. Based on the configured network, what IP address would PC1 and PC2 use as their default gateway?
192.168.1.1
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.
Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?
ARP
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.
What is a function of Layer 4 of the OSI model?
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.
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 happens when two devices on the same subnet are communicating?
The host portion of the IP addresses will be different.
Which statement is correct about network protocols?
They define how messages are exchanged between the source and the destination.
Match the TCP/IP layer to the protocol, service, or application that works within that layer. (Not all options are used.)
application layer -------- DNS; transport layer-------UDP; internet layer--------ICMP; network access layer------WLAN
Which message delivery option is used when all devices need to receive the same message simultaneously?
broadcast
What three functions are defined by network protocols to allow communication between known source and destination IP addresses? (Choose three.)
data encoding message size delivery options
Which logical address is used for delivery of data to a remote network?
destination IP address
Which address does a NIC use when deciding whether to accept a frame?
destination MAC address
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 type of delivery uses data link layer addresses?
local delivery
Which address provides a unique host address for data communications at the internet layer?
logical address
A computer in a given network is communicating 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
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
What is the purpose of protocols in data communications?
providing the rules required for a specific type of communication to occur
Which two message timing mechanisms are used in data communications? (Choose two.)
response timeout flow control
