organization promotes the open development, evolution, and use of the Internet
throughout the world.. Press spacebar to enter matching mode.
Match the description to the organization. (Not all options are
used.)
ISOC
This organization promotes the open development, evolution, and
use of the Internet throughout the world.
ISO
This organization is the largest developer of international
standards in the world for a wide variety of products and services. It is known
for its Open Systems Interconnection (OSI) reference model.
EIA
IANA
This organization is responsible
for overseeing and managing IP address allocation, domain name management, and
protocol identifiers.
2. What three application layer protocols are part of the TCP/IP
protocol suite? (Choose three.)
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.
