For a high bandwidth connection design, how many cross-connects should be created?

In a high bandwidth connection design, creating at least two or more cross-connects is essential. This approach ensures redundancy and reliability within the architecture. By having multiple cross-connects, you can maintain connectivity even if one path fails. This is particularly important in high availability environments where uptime is critical.

Additionally, multiple cross-connects can provide load balancing capabilities, allowing you to maximize the utilization of your bandwidth by distributing traffic across different paths. This improves overall performance and resilience against potential failures.

The other options suggest insufficient redundancy or entirely different configurations that may not meet high availability requirements. For instance, only one cross-connect limits the reliability of the connection, while the option suggesting only virtual circuits does not take into account the physical layer's reliability and redundancy that cross-connects provide. Hence, the selection of two or more cross-connects is appropriate for ensuring a robust and high-bandwidth connection design.
