What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?
encapsulation
flow control
access method
response timeout
What type of communication will send a message to all devices on a local area network?
broadcast
multicast
unicast
allcast
What process is used to place one message inside another message for transfer from the source to the destination?
access control
decoding
encapsulation
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, IP, TCP, Ethernet
HTTP, TCP, IP, Ethernet
Ethernet, TCP, IP, HTTP
Ethernet, IP, TCP, HTTP
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 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.
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 TCP/IP network access layer has similar functions to the OSI network layer.
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.
Refer to the exhibit. What is wrong with the displayed termination?
The woven copper braid should not have been removed.
The wrong type of connector is being used.
The untwisted length of each wire is too long.
The wires are too thick for the connector that is used.
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.
What three application layer protocols are part of the TCP/IP protocol suite? (Choose three.)
ARP
DHCP
DNS
FTP
NAT
What are proprietary protocols?
protocols developed by private organizations to operate on any vendor hardware
protocols that can be freely used by any organization or vendor
protocols developed by organizations who have control over their definition and operation
a collection of protocols known as the TCP/IP protocol suite
10. What is an advantage of network devices using open standard protocols?
Network communications is confined to data transfers between devices from the same vendor.
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.
Competition and innovation are limited to specific types of products.
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 and Internet layers
only Internet and network access layers
only application, Internet, and network access layers
application, transport, Internet, and network access layers
only application, transport, network, data link, and physical layers
Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)
application
transport
presentation
network
session
At which layer of the OSI model would a logical address be encapsulated?
physical layer
data link layer
network layer
transport layer
At which layer of the OSI model would a logical address be added during encapsulation?
physical layer
data link layer
network layer
transport layer
Refer to the exhibit. Host A is attempting to contact Server B. Which two statements correctly describe the addressing that Host A will generate in the process? (Choose two.)
A packet with the destination IP address of RouterB.
A frame with the destination MAC address of RouterA.
A frame with the destination MAC address of SwitchA.
A packet with the destination IP address of ServerB.
A frame with the destination MAC address of ServerB.
Which PDU is processed when a host computer is de-encapsulating a message at the transport layer of the TCP/IP model?
bits
frame
packet
segment
Which PDU format is used when bits are received from the network medium by the NIC of a host?
file
frame
packet
segment
Refer to the exhibit. The PC is connected to the console port of the switch. All the other connections are made through FastEthernet links. Which types of UTP cables can be used to connect the devices?
1 – rollover, 2 – crossover, 3 – straight-through
1 – rollover, 2 – straight-through, 3 – crossover
1 – crossover, 2 – straight-through, 3 – rollover
1 – crossover, 2 – rollover, 3 – straight-through
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.
Which characteristic describes the default gateway of a 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
the physical 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
What statement describes the function of the Address Resolution Protocol?
ARP is used to discover the IP address of any host on a different network.
ARP is used to discover the IP address of any host on the local network.
ARP is used to discover the MAC address of any host on a different network.
ARP is used to discover the MAC address of any host on the local network.
Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?
ARP
TCP
UDP
DHCP
A user sends an HTTP request to 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
the IP address of the destination host
the MAC address of the destination host
the IP address of the default gateway
Refer to the exhibit. Which statement describes the media access control methods that are used by the networks in the exhibit?
All three networks use CSMA/CA
None of the networks require media access control.
Network 1 uses CSMA/CD and Network 3 uses CSMA/CA.
Network 1 uses CSMA/CA and Network 2 uses CSMA/CD.
Network 2 uses CSMA/CA and Network 3 uses CSMA/CD.
