Which statement best describes a Leased Circuit?

A leased circuit, often referred to as a leased line, is a dedicated communication line provided by a telecommunications company that connects a single customer to a service provider's network. This type of circuit is exclusively available for the use of that specific customer, ensuring consistent performance, reliability, and a guaranteed bandwidth, as it is not shared with others.

Due to its dedicated nature, a leased circuit is ideal for businesses that require a stable and secure connection for transmitting data, voice, or video across sites. The isolation from other users also means that customers can achieve better security and control over their data traffic, a key advantage for business communications.

Shared access options, connections that operate on the general internet, and those restricted to voice communication do not accurately describe a leased circuit, as these would imply varying levels of shared resources or limited functionality, which are contrary to the exclusive and broad capabilities of leased lines.
