Question 1

A facial-recognition scanner is an example of a biometric authentication device.

Accepted Answer

A facial-recognition scanner uses unique biometric data from a person's face to verify their identity, making it an example of a biometric authentication device.

Question 2

MAC addresses and IP addresses are the same thing.

Accepted Answer

MAC addresses and IP addresses are not the same thing. MAC addresses are used to identify devices on a network at the local level, while IP addresses are used to identify devices on a network at the global level. MAC addresses are assigned by manufacturers, while IP addresses are assigned by network administrators or internet service providers.

Question 3

Crosstalk interference is the tendency of signals on one twisted-pair wire to interfere with signals on the wire next to it.

Accepted Answer

This is the definition of crosstalk interference.

Question 4

Since data transmissions can pass through fiber-optic cable in only one direction, at least two fibers are required to enable transmission of data in both directions.

Accepted Answer

This statement is true. In fiber-optic cables, data transmissions occur through pulses of light traveling along the fiber. Because the light can only travel in one direction, two fibers are required for transmission in both directions. One fiber is used for sending data, and the other is used for receiving data. This is known as full-duplex communication.

Question 5

Wireless access points can provide coverage wherever employees are working with portable devices, such as in conference rooms.

Accepted Answer

Wireless access points provide wireless connectivity and coverage for portable devices, allowing employees to connect to the internet and company networks wherever they are working within the range of the access point. This includes conference rooms, meeting areas, and other locations within a building or other facility.

Question 6

A bridge sends information between two networks.

Accepted Answer

A bridge connects multiple network segments within the same network, operating at the data link layer (Layer 2) of the OSI model, to make them act as a single network. It does not connect two different networks; that function is typically performed by a router.

Question 7

MAC addresses are restricted to Macintosh computers.

Accepted Answer

MAC (Media Access Control) addresses are not restricted to Macintosh computers. They are unique identifiers assigned to network interface controllers (NICs) of any device that can connect to a network, such as computers, smartphones, printers, routers, and other network devices.

Question 8

Transmission media comprise the physical system that data take to flow between devices on the network.

Accepted Answer

Transmission media refers to the physical means through which data travels between devices on a network, such as wires, cables, or airwaves.

Question 9

Worms often try to disguise from where they are sending data by using a bogus IP addresses instead of using an authorized IP address belonging to the network.

Accepted Answer

The answer of Worms often try to disguise from where...

Question 10

A phishing attack is an attempt to access an account by repeatedly trying different passwords.

Accepted Answer

A phishing attack is not an attempt to repeatedly try different passwords. It is a type of cyber attack where a malicious individual or group attempts to deceive a victim into providing sensitive information, such as login credentials or financial information, through fraudulent means such as fake emails or websites.
