The PrepKit covers 100% objectives for Cisco 640-802: CCNA: ICND1 and ICND 2 exam, in accordance with actual exam pattern and question types. Number of practice questions and study notes for each exam objective is as follows

QUESTION 101:
The PassGuide internetwork shown in the diagram is experiencing network delays.
On the basis of the information provided in the exhibit above, what is the problem?
A. The connection between Switch1 and Switch2 should be half-duplex.
B. The cable between Router1 and Switch1 should be a crossover.
C. The cable connecting Host A to Switch2 is too long.
D. The server is on a different subnet than router interface Fa0/0.
E. The cable between Switch1 and Switch2 should be straight-through.
F. None of the above
Answer: C
Explanation:
According to IEEE specifications, the maximum segment length of an Ethernet cable
should not exceed 100 meters. The total distance between an Ethernet Transmitter and
Receiver at the absolute end points of the network (maximum diameter from origin to
final destination, if the wires were stretched out to form a straight line) should be no
more than100 Meters (328 ft., 109 yards, or about the length of a football field). This
limitation results from the timing of the Ethernet signals on the cable and not necessarily
the cable characteristics, and is, therefore, a “hard” number.

QUESTION 102:
What is the IEEE standard associated with Gigabit Ethernet? (Select two answer
choices)
A. 802.11
B. 802.5
C. 802.3ab
D. 802.3ae
E. 802.3z
F. 802.3u
Answer: C, E
Explanation:
The IEEE 802.3z standard describes 1000BASE-SX.
The 1000BaseT standard was released in June 1999, defined by IEEE 802.3ab.
Incorrect Answers:
A. This describes the standard used for wireless networks.
B. This is the standard for token ring networks.
D. On June 17, 2002 the IEEE 802.3ae specification for 10 Gigabit Ethernet was
approved as an IEEE standard by the IEEE Standards Association (IEEE-SA) Standards
Board.
F. IEEE 802.3u describes the standard for 100BASE-TX.
QUESTION 103:
Which of the following can lead to the contribution of LAN traffic congestion?
(Select all that apply)
A. Too many hosts in a broadcast domain
B. Full duplex operation
C. Broadcast storms
D. Multicasting
E. Segmentation
F. Low bandwidth
Answer: A, C, F
Explanation:
Choice A is correct because the more hosts on a broadcast domain, the more traffic that is
640-802
Www.actualtest.org – The Power of Knowing
created. Choice Ccontributes to congestion because broadcast storms can become very
problematic, and lead to complete network saturation. Multicasts are similar to
broadcasts in their use on a LAN. Finally, if there is not enough bandwidth, traffic
sessions can time out. This leads to new transmissions and the re-sending of data, which
can lead to more congestion.
Incorrect Answers:
B, E. These are incorrect because full duplex operation and segmented networks actually
result in less congestion.
D. Multicasting can actually alleviate congestion issues, as single streams of information
can reach multiple hosts at the same time, instead of using a series of point to point
connections.
QUESTION 104:
On a half-duplex Ethernet LAN, two hosts attempt to send data simultaneously,
resulting in a collision. Following this collision, what will the hosts do? (Select all
valid answers)
A. The destination host sends a request to the source for retransmission.
B. The jam signal indicates that the collision has been cleared.
C. The hosts will attempt to resume transmission after a time delay has expired.
D. An electrical pulse indicates that the collision has cleared.
E. The router on the segment will signal that the collision has cleared.
F. The hosts will do nothing, as the higher layers are responsible for data error correction
and re-transmission.
Answer: C
Explanation:
When a host on an Ethernet LAN has information to send, the following steps are taken:
1. A device with a frame to send listens until Ethernet is not busy.
2. When the Ethernet is not busy, the sender begins sending the frame.
3. The sender listens to make sure that no collision occurred.
4. Once the senders hear the collision, they each send a jamming signal, to ensure that all
stations recognize the collision.
5. After the jamming is complete, each sender randomizes a timer and waits that long.
6. When each timer expires, the process starts over with step 1.
QUESTION 105:
Which of the following statements correctly describe the differences between
half-duplex and full-duplex Ethernet? (Select two answer choices.)
640-802
Www.actualtest.org – The Power of Knowing
A. Full-duplex Ethernet uses CSMA/CD to prevent collisions.
B. Half-duplex Ethernet uses a loopback circuit to detect collisions.
C. A full-duplex Ethernet card allows 20Mbps for data transmission.
D. Full-duplex Ethernet makes use of two pairs of wires for data.
E. An Ethernet hub can operate both half and full duplex simultaneously.
Answer: B, D
