I passed the paper, I prepared it from
www.examcheats.net I had no problems in paper.
statements are true about the operation of a full-duplex
Ethernet network? (Choose three.)
are no collisions in full-duplex mode.
B. A dedicated
switch port is required for each full-duplex node.
hub ports are preconfigured for full-duplex mode.
D. In a
full-duplex environment, the host network card must
check for the availability of the network media before
E. The host
network card and the switch port must be capable of
operating in full-duplex mode.
Ethernet is defined in the original 802.3 Ethernet and
Cisco says you only use one wire pair with a digital
signal running in both directions on the wire. It also
uses the CSMA/CD protocol to help prevent collisions
and to permit retransmitting if a collision does occur.
If a hub is attached to a switch, it must operate in
half-duplex mode because the end stations must be able
to detect collisions. Half-duplex Ethernet—typically
10BaseT—is only about 30 to 40 percent efficient as
Cisco sees it, because a large 10BaseT network will
usually only give you 3- to 4Mbps—at most.
Ethernet uses two pairs of wires, instead of one wire
pair like half duplex. Also, full duplex uses a point-to-point
connection between the transmitter of the transmitting
device and the receiver of the receiving device, which
means that with full-duplex data transfer, you get a
faster data transfer compared to half duplex. And because
the transmitted data is sent on a different set of wires
than the received data, no collisions occur. The reason
you don’t need to worry about collisions is because
now Full-duplex Ethernet is like a freeway with multiple
lanes instead of the single-lane road provided by half
duplex. Full-duplex Ethernet is supposed to offer 100
percent efficiency in both directions; this means you
can get 20Mbps with a 10Mbps Ethernet running full duplex,
or 200Mbps for FastEthernet.
are representative of a link-state routing protocol?
common view of entire topology
routing tables with neighbors
frequent periodic updates
layer header contains the address of a destination host
that is on another network?
of the TCP/IP stack combines the OSI model physical
and data link layers?
uses a connection-oriented service to deliver files
between end systems?
an acronym for File Transfer Protocol. As the name suggests,
FTP is used to transfer files between computers on a
network. You can use FTP to exchange files between computer
accounts, transfer files between an account and a desktop
computer, or access online software archives
uses the concept of areas. What are the characteristics
of OSPF areas? (Choose Three.)
OSPF area requires a loopback interface to be configured.
may be assigned any number from 0 to 65535.
0 is called the backbone area.
OSPF networks do not require multiple areas.
OSPF areas must connect to area 0.
area OSPF networks must be configured in area 1.
administrator is trying to add a new router into an
established OSPF network. The networks attached to the
new router do not appear in the routing tables of the
other OSPF routers. Given the information in the partial
configuration shown below, what configuration error
is causing this problem?
router ospf 1
network 10.0.0.0 255.0.0.0 area 0
A. The process
id is configured improperly.
B. The OSPF
area is configured improperly.
C. The network
wildcard mask is configured improperly.
D. The network
number is configured improperly.
E. The AS
is configured improperly.
F. The network
subnet mask is configured improperly.
the default maximum number of equal-cost paths that
can be placed into the routing table of a Cisco OSPF
the maximum number of parallel routes that Open Shortest
Path First (OSPF) can support, use the maximum-paths
number of parallel routes that OSPF can install in a
routing table. The range is from 1 to 16 routes.

statements describe the process identifier that is used
in the command to configure OSPF on a router? (Choose
router ospf 1
A. All OSPF
routers in an area must have the same process ID.
one process number can be used on the same router.
process identifiers can be used to run multiple OSPF
D. The process
number can be any number from 1 to 65,535.

describe the routing protocol OSPF? (Choose three.)
A. It supports
B. It is
used to route between autonomous systems.
C. It confines
network instability to one area of the network.
D. It increases
routing overhead on the network.
E. It allows
extensive control of routing updates.
F. It is
simpler to configure than RIP v2.
