On the media types listed below, which would be considered the most difficult to implement...
- A.
Wireless
- B.
Fiber Optic
- C.
Coaxial
- D.
UTP
Correct Answer
B. Fiber OpticExplanation
Fiber optic would be considered the most difficult media type to implement because it requires specialized equipment and expertise. Fiber optic cables use light signals to transmit data, which requires precise alignment and careful handling to avoid signal loss. The installation and maintenance of fiber optic cables also tend to be more complex and expensive compared to other media types. Additionally, fiber optic technology is constantly evolving, requiring ongoing training and updates to keep up with advancements.Rate this question:

The link light on a network interface card will light when which of the following happens?
- A.
The card is powered on
- B.
The wire connecting it to the network is plugged in
- C.
The power is turned on
- D.
The NIC starts receiving data
Correct Answer
B. The wire connecting it to the network is plugged inExplanation
The link light on a network interface card will light when the wire connecting it to the network is plugged in. This indicates that there is a physical connection between the NIC and the network, allowing for data transmission. The other options, such as the card being powered on or the power being turned on, may be necessary for the NIC to function, but they do not specifically cause the link light to light up. The link light serves as a visual indicator that the connection is established and active.Rate this question:
