encoding

access method
|
2. Refer to the graphic. Five PCs are connected
through a hub. If host H1 wants to reply to a message from host H2, which
statement is true?
|
H1 sends a unicast message to H2, but the hub
forwards it to all devices.
|
|
H1 sends a unicast message to H2, and the hub
forwards it directly to H2.
|
|
H1 sends a broadcast message to H2, and the
hub forwards it to all devices.
|
|
H1 sends a multicast message to H2, and the
hub forwards it directly to H2.
|
3. Which two statements concerning networking
standards are true?
|

type of cable used
|
|
type of data transmission
|
|
speed of transmission
|
|
type of connector required
|
|
maximum length of cable allowed
|
5. Which address does an NIC use when deciding
whether to accept a frame?
|
source IP address
|
|
source MAC address
|
|
destination IP address
|
|
destination MAC address
|
|
source Ethernet address
|
6. Which type of address is used in an Ethernet
frame header?
|
logical addresses only
|
|
IP addresses only
|
|
MAC addresses only
|
|
broadcast addresses only
|
7. What is the function of the FCS field in an
Ethernet frame?
|
detects transmission errors
|
|
provides timing for transmission
|
|
contains the start of frame delimiter
|
|
indicates which protocol will receive the
frame
|
8. What is the purpose of logical addresses in
an IP network?
|
They identify a specific NIC on a host
device.
|
|
They are used to determine which host device
accepts the frame.
|
|
They provide vendor-specific information
about the host.
|
|
They are used to determine the network that
the host is located on.
|
|
They are used by switches to make forwarding
decisions.
|
9. Which device accepts a message on one port
and always forwards the message to all other ports?
|
modem
|
|
switch
|
|
router
|
|
hub
|
10. Which two networking devices are used to
connect hosts to the access layer?
|
hub and switch
|
|
switch and router
|
|
hub and router
|
|
switch and computer
|
|
client and server
|
11. Host A needs to learn the MAC address of
Host B, which is on the same LAN segment. A message has been sent to all the
hosts on the segment asking for the MAC address of Host B. Host B responds with
its MAC address and all other hosts disregard the request. What protocol was
used in this scenario?
|
ARP
|
|
DHCP
|
|
DNS
|
|
WINS
|
12. A switch receives a frame with a
destination MAC address that is currently not in the MAC table. What action
does the switch perform?
|
It drops the frame.
|
|
It sends out an ARP request looking for the
MAC address.
|
|
It floods the frame out of all active ports,
except the origination port.
|
|
It returns the frame to the sender.
|
13. What is a benefit of having a router within
the distribution layer?
|
prevents collisions on a local network
|
|
keeps broadcasts contained within a local
network
|
|
controls which hosts have access to the
network
|
|
controls host-to-host traffic within a single
local network
|
14.
Refer to the graphic. What does the router do
after it determines that a data packet from Network 1 should be forwarded to
Network 2?
|
It sends the data packet as it was received.
|
|
It reassembles the frame with different MAC
addresses than the original frame.
|
|
It reassembles the data packet with different
IP addresses than the original data packet.
|
|
It reassembles both the packet and the frame
with different destination IP and MAC addresses.
|
15. Which table does a router use to make
decisions about the interface through which a data packet is to be sent?
|
ARP table
|
|
routing table
|
|
network table
|
|
forwarding table
|
16. If the default gateway is configured
incorrectly on the host, what is the impact on communications?
|
The host is unable to communicate on the
local network.
|
|
The host can communicate with other hosts on
the local network, but is unable to communicate with hosts on remote
networks.
|
|
The host can communicate with other hosts on
remote networks, but is unable to communicate with hosts on the local
network.
|
|
There is no impact on communications.
|
17. What device is typically used as the
default gateway for a computer?
|
a server hosted by the ISP
|
|
the router interface closest to the computer
|
|
a server managed by a central IT department
|
|
the switch interface that connects to the
computer
|
18. What type of route allows a router to
forward packets even though its routing table contains no specific route to the
destination network?
|
dynamic route
