A network administrator has been tasked with creating a disaster recovery plan. As part of this plan, the administrator is looking for a backup site for all of the data on the company servers. What service or technology would support this requirement?

For creating a disaster recovery plan that includes a backup site for all of the data on the company servers, the service or technology that would support this requirement is a data center.

A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A data center can be used to create a secure and resilient environment where a backup of the company’s servers and data can be stored.

Here’s a brief explanation of the other options:

1. Virtualization: This technology allows you to create and manage multiple virtual instances of devices (like servers) on a single set of hardware. While virtualization is a key component of modern disaster recovery solutions because it allows for rapid provisioning and flexibility, it is not a service or technology for offsite data storage by itself.
2. Software Defined Networking (SDN): SDN is an approach to networking that uses software-based controllers or application programming interfaces (APIs) to direct traffic on the network and communicate with the underlying hardware infrastructure. It’s more about managing network resources efficiently and doesn’t directly relate to data storage for disaster recovery.
3. Dedicated Servers: These are physical servers dedicated to a single customer or task. While they can be part of a disaster recovery plan, the term ‘dedicated servers’ by itself doesn’t imply a backup site or disaster recovery functionality.

For the specified need of a backup site for disaster recovery, a data center is the most relevant because it can provide a secure and resilient offsite location to store critical backups and ensure business continuity in the event of a disaster.
