A network administrator is planning to expand the company's infrastructure to include a second data center. They intend to set up a DCI to ensure high availability and optimized disaster recovery processes. Which technology is most appropriate for creating a high-capacity, secure, and scalable interconnect between these data centers?
Multiprotocol Label Switching (MPLS) is most appropriate for creating DCIs due to its ability to support high-capacity bandwidth and its proficiency in managing data packets through labels, facilitating efficient data routing. MPLS also provides reliability, various Quality of Service (QoS) levels, and traffic engineering capabilities, making it ideal for interconnecting data centers. Other answers, while related to networking technologies, are not as suited. Point-to-Point Protocol is typically used for direct connections between two nodes rather than high-capacity data center interconnections, and Dark Fiber, although offering high capacity, lacks inherent routing and QoS features critical for complex DCI. Lastly, VPN is more suited for secure, single connections over the internet and does not necessarily provide the scalability required for robust DCI.
