Braindumps for "N10-003" Exam

Network+ (2008)

 Question 1.
If one of the links to a computer on a physical star topology is served, what will be the result?

A. The entire network will stop working.
B. The affected link and the adjacent network links will stop working.
C. Only the affected link will stop working.
D. Only the adjacent links will stop working.

Answer: C

In the star topology each computer is connected to a central point by a separate cable or wireless connection. Thus each computer has a dedicated link to the network central device and a break in the link between a particular computer and the central network device will affect only that computer.

Question 2.
When one connection to a host fails in a full mesh network, which of the following is true?

A. All hosts can communicate
B. No hosts can communicate
C. Half of the host will lose communication
D. Only the two hosts between the failed connection will lose communication

Answer: A

In a full mesh network, each node has a connection to at two other nodes. Thus, should one connection fail, it will have no effect on communication as all nodes will be connected to at least one other node.

CA, 2005, pp. 14-15.

Question 3.
Which of the following network topologies uses the most cable?

A. Star
B. Ring
C. Bus
D. Mesh

Answer: D

In the mesh topology, each node is connected to at least three other nodes. This requires more cabling than in the ring or bus topology, in which each node is connected to only two other nodes, or the star topology, in which each node is connected to a central hub or switch.

Incorrect Answers:
A: In the star topology, each node is connected to a central hub or switch. This requires less cabling than in the mesh topology, in which each node is connected to at least three other nodes.
B: In the ring topology consists of a closed loop in which each node is connected to the node ahead of it and the node behind it in the loop. This requires less cabling than in the mesh topology, in which each node is connected to at least three other nodes.
C: The bus topology is similar to the ring topology, except that the cable does not form a complete loop, but is terminated at each end. Each node, except the nodes at the end points, is connected to the node ahead of it and the node behind it along the cable. This requires less cabling than in the mesh topology, in which each node is connected to at least three other nodes.

Question 4.
Which of the following network topologies uses the least cable?

A. Star
B. Ring
C. Bus
D. Mesh

Answer: C

The bus topology consists of a single cable that connects the network nodes. Both ends of the cable are terminated just after the last node. Each node, except the nodes at the end points, is connected to the node ahead of it and the node behind it along the cable. This requires least amount of cabling.

Incorrect Answers:
A: In the star topology, each node is connected to a central hub or switch. This requires more cabling than in the bus topology, in which the nodes are connected on a single trunk cable that is terminated just after the last nodes at either end.
B: In the ring topology consists of a closed loop in which each node is connected to the node ahead of it and the node behind it in the loop. This requires more cabling than in the bus topology, in which the nodes are connected on a single trunk cable that is terminated just after the last nodes at either end and does not need to connect the ends together to form a loop.
C: In the mesh topology, each node is connected to at least three other nodes. This requires more cabling than in the ring or bus topology, in which each node is connected to only two other nodes, or the star topology, in which each node is connected to a central hub or switch.

Question 5.
Which of the following networking topology requires the MOST physical connections per node?

A. Bus
B. Ring
C. Star
D. Mesh

Answer: D

In the mesh topology, each node is connected to at least three other nodes. This requires more connections per node than in the ring or bus topology, in which each node is connected to only two other nodes, or the star topology, in which each node is connected to a central hub or switch.

Incorrect Answers:
A: In the star topology, each node is connected to a central hub or switch. This requires fewer connections per node than in the mesh topology, in which each node is connected to at least three other nodes.
B: In the ring topology consists of a closed loop in which each node is connected to the node ahead of it and the node behind it in the loop. This requires fewer connections per node than in the mesh topology, in which each node is connected to at least three other nodes.
C: The bus topology is similar to the ring topology, except that the cable does not form a complete loop, but is terminated at each end. Each node, except the nodes at the en points, is connected to the node ahead of it and the node behind it along the cable. This requires fewer connections per node than in the mesh topology, in which each node is connected to at least three other nodes.

Question 6.
At which of the following speeds does token ring operate?

A.1 Mbps, 10 Mbps (Megabit per second)
B. 1 Mbps, 4 Mbps (Megabit per second)
C. 4 Mbps, 16 Mbps (Megabit per second)
D. 10 Mbps, 100 Mbps (Megabit per second)

Answer: C

Token ring initially operated at 4 Mbps. This was later increased to 16 Mbps.

References:
David Groth and Toby Skandier, Network+ Study Guide (4th Edition), Sybex, Alameda CA, 2005, p. 65.

Question 7.
Which frequency band is used in the IEEE 802.11b standard?

A. 1.5 GHz (Gigahertz)
B. 2.4 GHz (Gigahertz)
C. 5.0 GHz (Gigahertz)
D. 7.0 GHz (Gigahertz)

Answer: B

IEEE 802.11, IEEE 802.11b and IEEE 802.11g uses the 2.4 GHz frequency band.

Incorrect Answers:
A, D: NoIEEE wireless standard uses the 1.5 GHz or the 7.0 GHz frequency bands.
C: IEEE802.11a uses the 5.0 GHz frequency band, not 802.11b.

References:
David Groth and Toby Skandier, Network+ Study Guide (4th Edition), Sybex, Alameda
CA, 2005, pp. 249-252.

Question 8.
Which standard covers the methods for performing authentication services for wireless access to a central LAN (Local Area Network)?

A. 802.5
B. 802.1x
C. 802.3
D. 802.4

Answer: B

802.1x is an authentication method for authenticating wireless users and requires them to authenticate at the WAP before they are granted access to the network.

Incorrect Answers:
A: 802.5 defines Token Ring.
C: 802.3 defines Ethernet.
D: 802.4 defines Token Bus.

References:
David Groth and Toby Skandier, Network+ Study Guide (4th Edition), Sybex, Alameda CA, 2005, pp. 63-65, 340.

Question 9.
Which of the following IEEE (Institute of Electrical and Electronics Engineers) standards represents Ethernet?

A. 802.0
B. 802.3
C. 802.5
D. 802.11

Answer: B

The IEEE 802.3 standard defines a network that uses a bus topology, baseband signaling, and a CSMA/CD network access method. This standard was developed to match the
Digital, Intel, and Xerox (DIX) Ethernet networking technology and is referred to as Ethernet.

Incorrect Answers:
A: There is not IEEE 802.0 standard.
C: IEEE 802.5 represents Token Ring, not Ethernet.
D: IEEE 802.11 represents Wireless LAN, not Ethernet.

References:
David Groth and Toby Skandier, Network+ Study Guide (4th Edition), Sybex, Alameda CA, 2005, pp. 63-66.

Question 10.
Which of the following topologies does FDDI (Fiber Distributed Data Interface) require?

A. Star
B. Bus
C. Ring
D. Mesh

Answer: C

FDDI is a token-passing network using fiber-optic cable. It is similar to Token Ring but uses two rings that counter-rotate instead of one ring. If a failure occurs, the counter-rotating rings can join together forming a ring around the fault, thus isolating the fault and allowing communications to continue.
