ARP
NAT
PPP
DHCP
DNS
FTP



3. Which statement is true about the TCP/IP and OSI models?​
The OSI Layer 7 and the TCP/IP application layer provide identical functions.
The TCP/IP network access layer has similar functions to the OSI network layer.​
The TCP/IP transport layer and OSI Layer 4 provide similar services and functions.​
The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.​



4. What process is used to place one message inside another message for transfer from the source to the destination?
access control
flow control
decoding
encapsulation



5. At which layer of the OSI model would a logical address be added during encapsulation?
transport layer
data link layer
physical layer
network layer

6 .
Option 3: message encapsulation. Press spacebar to enter matching mode. 
Match each description to its corresponding term. (Not all options are used.)


the process of determining when to begin sending messages on a network
                                                                                                            
the process of converting information from one format into another acceptable for transmission
message encoding
the process of placing one message format inside another message format
message sizing
the process of unpacking one message format from another message format
                                                                                                            
the process of breaking up a long message into individual pieces before being sent over the network
message encapsulation

7. What is an advantage of network devices using open standard protocols?
Network communications is confined to data transfers between devices from the same vendor.
Competition and innovation are limited to specific types of products.
A client host and a server running different operating systems can successfully exchange data.
Internet access can be controlled by a single ISP in each market.



8. Which characteristic describes the default gateway of a host computer?
the physical address of the switch interface connected to the host computer
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
the logical address assigned to the switch interface connected to the router



9. What are proprietary protocols?
protocols that can be freely used by any organization or vendor
protocols developed by organizations who have control over their definition and operation
protocols developed by private organizations to operate on any vendor hardware
a collection of protocols known as the TCP/IP protocol suite



10. Which statement is correct about network protocols?
They define how messages are exchanged between the source and the destination.
They all function in the network access layer of TCP/IP.
They are only required for exchange of messages between devices on remote networks.
Network protocols define the type of hardware that is used and how it is mounted in racks.



11. 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
access method
encapsulation
response timeout


12. 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 switch will not forward packets initiated by the host.
The host will have to use ARP to determine the correct address of the default gateway.
The host cannot communicate with hosts in other networks.
A ping from the host to 127.0.0.1 would not be successful.



13. What is an advantage of using standards to develop and implement protocols?
A particular protocol can only be implemented by one manufacturer.
Products from different manufacturers can interoperate successfully.
Standards provide flexibility for manufacturers to create devices that comply with unique requirements.
Different manufacturers are free to apply different requirements when implementing a protocol.



14. Which PDU format is used when bits are received from the network medium by the NIC of a host?
segment
frame
file
packet



15. What type of communication will send a message to all devices on a local area network?
multicast
allcast
unicast
broadcast



16. Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
application
transport
session
physical
network
presentation
data link



17.
Host1 connects to Switch1 and then to Router1. Router1 connects to Router2 via a serial link. Router2 connects to Switch2 and Switch2 connects to a server. Router2 also connects to an ISP via a serial link.
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, session, transport, network, data link, and physical layers
only Internet and network access layers
only application and Internet layers
only application, transport, network, data link, and physical layers
application, transport, Internet, and network access layers
only application, Internet, and network access layers



18. Which address does a NIC use when deciding whether to accept a frame?
source MAC address
destination MAC address
destination IP address
source Ethernet address
source IP address



19. 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?
Ethernet, IP, TCP, HTTP
HTTP, IP, TCP, Ethernet
Ethernet, TCP, IP, HTTP
HTTP, TCP, IP, Ethernet



20. Option 4: taking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses. Press spacebar to enter matching mode. 
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.)


application protocol
governing the way a web server and a web client interact
internet protocol
taking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses
network access protocol
preparing packets to be transmitted over the network media
network time protocol
                                                                                                            
transport protocol
managing the individual conversations between web servers and web clients



21. Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
frame
segment
bits
packet



22. 
 
HostA is connected to RouterA through SwitchA. RouterA connects to RouterB via a serial link. RouterB is connected to ServerB through SwitchB.
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 ServerB.
A frame with the destination MAC address of SwitchA.
A packet with the destination IP address of RouterA.
A packet with the destination IP address of RouterB.
A frame with the destination MAC address of ServerB.
A frame with the destination MAC address of RouterA.
