What are the available options to interconnect private Datacenters? (Select 2)

Suggested Answer: A, B

The available options to interconnect private Datacenters are VPN and Backbone. VPN stands for Virtual Private Network, which is a secure and encrypted connection between two or more networks over the public internet. Backbone is a high-capacity network that connects different data centers across regions or countries. Both VPN and Backbone provide reliable, scalable, and secure data center interconnect (DCI) solutions for private/hybrid clouds.Reference:Nokia Cloud DCI offers a more scalable, reliable and secure way to connect data centers in private/hybrid clouds,Nokia business-critical cloud DCI solutions support multiple DCI applications, from real-time business continuity and disaster recovery, to synchronous data replication and cloud backup,Nokia partners with IP Telecom to deliver quantum-safe data center connectivity
