Which RG rating of coax is used for cable modems?
- A.
RG-58
- B.
RG-8
- C.
RG-6
- D.
RG-59
Correct Answer
C. RG-6Explanation
RG-6 is the correct answer because it is the most commonly used coaxial cable for cable modems. RG-6 cables have a higher bandwidth capacity and are better suited for transmitting high-frequency signals, making them ideal for high-speed internet connections. They have better shielding and lower signal loss compared to other RG ratings, ensuring reliable and efficient data transmission for cable modems.Rate this question:

Which UTP uses four twisted wire pairs (eight wires), is rated for 100MHz, and is capable of handling the disturbance on each pair caused by transmitting on all four pairs at the same time?
- A.
Cat-5
- B.
Cat-5e
- C.
Cat-6
- D.
Cat-6a
Correct Answer
B. Cat-5eExplanation
Cat-5e is the correct answer because it uses four twisted wire pairs (eight wires), is rated for 100MHz, and is capable of handling the disturbance on each pair caused by transmitting on all four pairs at the same time. Cat-5 is not capable of handling the disturbance caused by transmitting on all four pairs simultaneously. Cat-6 and Cat-6a have higher bandwidth ratings (250MHz and 500MHz respectively), but they are not necessary for this specific requirement.Rate this question:

Two twisted wire pairs (four wires). It's the oldest type and is only voice grade — it isn't rated for data communication. People refer to it as plain old telephone service (POTS). Before 1983, this was the standard cable used throughout the North American telephone system. POTS cable still exists in parts of the Public Switched Telephone Network (PSTN) and supports signals limited to the 1MHz frequency range.

Cat 6
Correct Answer
A. Cat 1Explanation
The given correct answer is Cat 1. This is because Cat 1 cable, also known as Category 1 cable, is the oldest type of cable and is only suitable for voice grade communication. It is not rated for data communication. The description provided matches the characteristics of Cat 1 cable, as it is referred to as plain old telephone service (POTS) and was the standard cable used before 1983 in the North American telephone system. Therefore, Cat 1 is the correct answer.Rate this question:

B. Cat 2Explanation
Cat 2 is the correct answer because it is the closest match to the given description. Cat 2 cables consist of four twisted wire pairs, which matches the description of "Four twisted wire pairs (eight wires)". Cat 2 cables have a maximum data transfer rate of 4Mbps, which matches the given information. The frequency limitation of 10MHz also aligns with Cat 2 cables, as they are designed for lower frequency applications. Additionally, Cat 2 cables are now obsolete, which matches the information provided.Rate this question:

G. Cat 6Explanation
Cat 6 cable is the correct answer because it is a twisted wire pair cable that is rated for 250MHz, making it suitable for connecting floors together. It became a standard in June 2002, indicating its reliability and widespread use. When installing a new network in a new building, Cat 6 cable is recommended due to its superior performance compared to lower category cables such as Cat 1, Cat 2, Cat 3, Cat 4, Cat 5, and Cat 5e. Additionally, running fiber optic cables between floors is also suggested for optimal network connectivity.Rate this question:

CSMA/CD
Correct Answer
Carrier Sense Multiple Access with Collision DetectionExplanation
CSMA/CD is a protocol used in Ethernet networks to control access to the shared transmission medium. "Carrier Sense" refers to the process of checking if the network is currently being used by another device before transmitting data. "Multiple Access" means that multiple devices can access the network simultaneously. "Collision Detection" is the mechanism used to detect if two devices transmit data at the same time, causing a collision. In such cases, both devices stop transmitting and wait for a random time before retransmitting. Therefore, CSMA/CD is the correct answer as it accurately describes the protocol's functionality.Rate this question:
