What is a data center interconnection?

A data center interconnection refers to the logical connectivity between data centers. This connectivity enables different data centers to communicate and share resources effectively, facilitating the transfer of data, redundancy, and load balancing among various facilities. This type of interconnection is critical for businesses that rely on multiple data centers to ensure high availability and disaster recovery capabilities.

Through data center interconnection, organizations can create a more resilient network by connecting geographically dispersed data centers, improving overall performance, and optimizing resource utilization. It allows for the aggregation and distribution of services across multiple sites, which can enhance scalability and efficiency.

The other options do not accurately define what a data center interconnection entails. For instance, server redundancy focuses on having backup servers to prevent downtime, while network switch protocols are concerned with how data is forwarded within networks. A power backup system is aimed at providing uninterrupted power supply rather than connectivity between data centers. Thus, the best understanding of data center interconnection is its role in facilitating logical connectivity, making option B the correct choice.
