CISSP®- Risk Management - Identification

The video tutorial covers various wireless network technologies, starting with Lifi, which uses light for communication and is beneficial in EMI-prone areas. It then explains Zigbee, a low-power network suitable for close proximity communication. The discussion moves to satellite internet, highlighting its high latency and cost, but also its potential with advancements like Starlink. Finally, the tutorial explores cell networks, detailing the evolution from 3G to 5G, emphasizing speed, coverage, and latency improvements.

What is a key advantage of LiFi over Wi-Fi in areas with high Wi-Fi congestion?

• LiFi is unaffected by Wi-Fi congestion.

• LiFi can penetrate walls better than Wi-Fi.

• LiFi has a longer range than Wi-Fi.

• LiFi is cheaper to implement than Wi-Fi.

Which of the following is a characteristic of Zigbee networks?

• Low power consumption

• Long range

• Requires no line of sight

• High data rates

What has historically been a major drawback of satellite internet connections?

• High cost

• High speed

• Wide coverage

• Low latency

Why is the speaker interested in Starlink for satellite internet?

• It offers lower latency.

• It is the cheapest option available.

• It does not require a dish.

• It has the widest coverage.

What is a significant difference between 4G and 5G networks?

• 5G has a larger coverage area than 4G.

• 4G is faster than 5G.

• 4G has higher latency than 5G.

• 5G requires fewer antennas than 4G.

Which network technology is known for having the smallest coverage area per antenna?

• 4G

• Wi-Fi

• 5G

• 3G

What is a common feature of cell networks that ensures seamless user experience?

• Cells are spaced far apart to avoid interference.

• All cells use the same frequency.

• Cells overlap to provide full coverage.

• Each cell has its own unique network.
