Which technology can be used for last-mile circuit protection?

The choice of microwave and coaxial cables as the correct answer in the context of last-mile circuit protection is based on their roles in telecommunications and data transmission networks. Last-mile circuits refer to the final leg of the telecommunications networks that deliver internet and telephone services to customers. These circuits are crucial for ensuring the reliability and integrity of the services delivered.

Microwave cables, often used in point-to-point communication systems, facilitate line-of-sight transmission of data over long distances, making them effective for last-mile applications where traditional wired connections might be difficult or impractical. Coaxial cables, on the other hand, are commonly used for cable television and internet service providers to connect facilities to homes or businesses. They support high bandwidth and are capable of withstanding signal interference, thereby ensuring reliable connections to end-users.

Both types of cables can include protective measures designed to minimize disruptions from external factors, such as environmental changes or physical damage, which are critical for the integrity of last-mile connections.

In comparison, Wi-Fi routers primarily facilitate wireless connectivity and do not inherently protect last-mile circuits; they serve as access points rather than transmission lines. Server farms, while essential for data processing, are not involved in the actual delivery of last-mile connectivity to users. Traditional phone lines
