decoding
flow control
encapsulation
access control
- 2. Multiple Choice
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, IP, TCP, Ethernet
HTTP, TCP, IP, Ethernet
Ethernet, TCP, IP, HTTP

- 3. Multiple Choice
Which statement is correct about network protocols?
They all function in the network access layer of TCP/IP.
They define how messages are exchanged between the source and the destination.
Network protocols define the type of hardware that is used and how it is mounted in racks.
They are only required for exchange of messages between devices on remote networks.
- 4. Multiple Choice
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
The OSI Layer 7 and the TCP/IP application layer provide identical functions.
The first three OSI layers describe general services that are also provided by the TCP/IP internet layer.
The TCP/IP network access layer has similar functions to the OSI network layer.
- 5. Multiple Choice
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.
Different manufacturers are free to apply different requirements when implementing a protocol.
Standards provide flexibility for manufacturers to create devices that comply with unique requirements.
- 6. Multiple Choice
What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
PPP
DHCP
DNS
NAT
FTP
- 7. Multiple Choice
What are proprietary protocols?
a collection of protocols known as the TCP/IP protocol suite
protocols developed by organizations who have control over their definition and operation
protocols that can be freely used by any organization or vendor
protocols developed by private organizations to operate on any vendor hardware
- 8. Multiple Choice
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.
Internet access can be controlled by a single ISP in each market.
Network communications is confined to data transfers between devices from the same vendor.
Competition and innovation are limited to specific types of products.
- 9. Multiple Choice
Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?
only application, Internet, and network access layers
application, transport, Internet, and network access layers
only application and Internet layers
only Internet and network access layers
application, session, transport, network, data link, and physical layers
- 10. Multiple Choice
Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
session
physical
transport
presentation
application
- 11. Multiple Choice
At which layer of the OSI model would a logical address be added during encapsulation?
network layer
transport layer
data link layer
physical layer
- 12. Multiple Choice
Which PDU format is used when bits are received from the network medium by the NIC of a host?
segment
packet
frame
file
bit
- 13. Multiple Choice
Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
segment
packet
frame
bits
- 14. Multiple Choice
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 SwitchA.
A packet with the destination IP address of RouterB
A frame with the destination MAC address of RouterA
A packet with the destination IP address of ServerB.
A frame with the destination MAC address of ServerB.
- 15. Multiple Choice
Which address does a NIC use when deciding whether to accept a frame?
source Ethernet address
destination MAC address
destination IP address
source MAC address
source IP address
- 16. Multiple Choice
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.
- 17. Multiple Choice
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
the physical address of the switch interface connected to the host computer
- 18. Multiple Choice
Message Encoding
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
the process of placing one message format inside another message format
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
- 19. Multiple Choice
message sizing
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
the process of placing one message format inside another message format
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
- 20. Multiple Choice
message encapsulation
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
