1. At which layer of the OSI model would a logical address be encapsulated?
network layer
You are viewing: Which Statement Is True About The Tcp/ip And Osi Models
data link layer
physical layer
transport layer
2. What are proprietary protocols?
protocols developed by private organizations to operate on any vendor hardware
protocols developed by organizations who have control over their definition and operation
a collection of protocols known as the TCP/IP protocol suite
protocols that can be freely used by any organization or vendor
3. Which address does a NIC use when deciding whether to accept a frame?
Destination IP address
source Ethernet address
source MAC address
source IP address
destination MAC address
4. Match the description to the organization. (Not all options are used.)
ISOC -> The organization promotes the open development, evolution, and use of the internet throughout the world
ISO -> This organization is the largest developer of international standars in the world for a wide variety of products and services. It is know for its Open System Interconection (OSI) reference model.
IANA -> This organization is responsible for overseeing and managing IP address allocation, domain name management, and protocol identifiers
5. Match each description to its corresponding term. (Not all options are used.)
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
message sizing -> the process of breaking up a long message into individual pieces before being sent over the network
6. Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
data link
presentation
application
network
session
physical
transport
7. What process is used to place one message inside another message for transfer from the source to the destination?
access control
flow control
encapsulation
decoding
8. Which statement is correct about network protocols?
Network protocols define the type of hardware that is used and how it is mounted in racks.

They all function in the network access layer of TCP/IP.
They are only required for exchange of messages between devices on remote networks.
They define how messages are exchanged between the source and the destination.
9. What is an advantage of using standards to develop and implement protocols?
Different manufacturers are free to apply different requirements when implementing a protocol.
Products from different manufacturers can interoperate successfully.
A particular protocol can only be implemented by one manufacturer.
Standards provide flexibility for manufacturers to create devices that comply with unique requirements.
10. 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
HTTP, IP, TCP, Ethernet
Ethernet, IP, TCP, HTTP
Ethernet, TCP, IP, HTTP
11. 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
talking the segments from the 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
managing the individual conversation between web servers and web clients -> transport protocol
12. Which statement is true about the TCP/IP and OSI models?
The TCP/IP network access layer has similar functions to the OSI network layer.
The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.
The OSI Layer 7 and the TCP/IP application layer provide identical functions.
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.
13. What is an advantage of network devices using open standard protocols?
Internet access can be controlled by a single ISP in each market.
A client host and a server running different operating systems can successfully exchange data.
Network communications is confined to data transfers between devices from the same vendor.
Competition and innovation are limited to specific types of products.
14. 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
only application, Internet, and network access layers
only application and Internet layers
only application, transport, network, data link, and physical layers
application, session, transport, network, data link, and physical layers
only Internet and network access layers
15. Which characteristic describes the default gateway of a host computer?
the logical address assigned to the switch interface connected to the router
the physical address of the router interface on the same network as the host computer
the logical address of the router interface on the same network as the host computer
Read more : Which Vaccine Route and Site is Right for You?
the physical address of the switch interface connected to the host computer
16. 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 packet with the destination IP address of RouterA.
A frame with the destination MAC address of RouterA.
A packet with the destination IP address of RouterB.
A packet with the destination IP address of ServerB.
A frame with the destination MAC address of ServerB.
A frame with the destination MAC address of SwitchA.
17. What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
DHCP
FTP
DNS
NAT
PPP
ARP
18. Which PDU format is used when bits are received from the network medium by the NIC of a host?
frame
segment
packet
file
19. Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
bits
segment
frame
packet
20. What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
Access method
encapsulation
response timeout
flow control
21. What will happen if the default gateway address is incorrectly configured on a host?
The host cannot communicate with other hosts in the local network.
The host cannot communicate with hosts in other networks.
The switch will not forward packets initiated by the host.
A ping from the host to 127.0.0.1 would not be successful.
The host will have to use ARP to determine the correct address of the default gateway.
22. What type of communication will send a message to all devices on a local area network?
Multicast
unicast
allcast
broadcast
