Question 15

Which of the following media types is least susceptible to cross talk?
A)UTP
B)STP
C)Co-axial
D)Fiber optic

Accepted Answer

The media type that is least susceptible to cross talk is fiber optic. Fiber optic is advantageous for long-distance communication because light propagates through the fiber with little attenuation compared with other electrical standards. This allows long distances to be spanned with few repeaters.
Key Takeaway: Crosstalk refers to any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. It is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel to another.

Question 16

Which of the following is a default subnet mask for a Class B network?
A)255.0.0.0
B)255.255.255.0

D)255.255.0.0

Accepted Answer

The default subnet mask for Class B is 255.255.0.0.
Key Takeaway: A class B subnet uses the first and second octets of an IP address to designate the network ID and the remaining two octets for the designation of the Host ID. The first two bits of the first octet are always set to one zero, 10 to indicate a Class B address. This leaves 14 bits to represent the Network ID giving 16,384 possible network addresses. The remaining 16 bits are available to designate the host ID, providing for 65,534 hosts per network.

Question 17

Mark is in charge of the network support team in his organization. Currently the wireless network is experiencing interference issues from a nearby wireless network using different SSIDs but operating on the same channel. What should he do to solve this problem?
A)Change the LAN WAP channel to a unique one.
B)Change the LAN WAP to the same SSID as the foreign WAP.
C)Change the WEP settings on the LAN.
D)Change the LAN WAP settings to be different than that of the foreign WAP.

Accepted Answer

To avoid interference issues between different SSIDs operating on the same channel, change the channel to a unique one.
Key Takeaway: The interference is a result of the proximity of the foreign wireless LANs. Because they are using the same channel, the wireless LANs interfere with each other's signals. The interference can be reduced by changing the channel used by the WLAN under consideration.

Question 18

David calls into his manufacturer's technical support in order to resolve an issue with his Internet/network access. The technician asks for any changes made to the computer. David says he replaced a network card on the PCI slot. What should the technician do next?

C)Check the processor speed.
D)Check the user password.

Accepted Answer

The technician should check if the NIC is working correctly. The NIC may have been reseated incorrectly or may be faulty.
Key Takeaway: When troubleshooting, you should check the condition that changed first, as this is the most likely cause of the problem. In this case, the NIC has been changed. Therefore, we should check the NIC to ensure that it is operating properly.

Question 19

Which of the following is a unique 48-bit number that uniquely identifies an adapter on the network?
A)MAC address
B)IP address
C)Default gateway
D)Subnet mask

Accepted Answer

MAC address is the 48 bit unique identifier on the NIC.
Key Takeaway: Media Access Control address (MAC address) is a unique identifier assigned to network adapters or network interface cards (NICs) by the manufacturer, primarily for unique identification on the Internet.

Question 20

David was able to connect his computer to the Internet successfully at his place. However, when he tried to connect his computer at his friend's place, it wouldn't connect to the Internet. The Internet connection is working fine since his friend is able to connect to the Internet on the same connection. What should David check for?
A)Check if his friend's connection uses automatic IP addressing or manual IP addressing.
B)Check if he can ping the loopback address.
C)Check the IP address on his computer.
D)Check if he can ping the default gateway.

Accepted Answer

If David is unable to connect his computer to the Internet, he should check if his friend's connection uses automatic IP addressing or manual IP addressing. Theremay be an issue with the addressing scheme.
Key Takeaway: There are 2 types of IP address assignment schemes: automatic IP addressing, where an IP address is provided from a DHCP server, and manual IP assignment, where the IP address is entered manually along with the default gateway and subnet mask. If David's friend is able to connect to the internet, it means that the connection is fine. He may be using a manually configured IP. So David has to configure a static IP or manual IP on his computer.
