The primary advantage of an organization using Disaster Recovery as a Service (DRaaS) to help manage its disaster recovery program is B. It allows the organization to prioritize its core operations. This is because DRaaS is a cloud computing service model that allows an organization to back up its data and IT infrastructure in a third-party cloud computing environment and provide all the disaster recovery orchestration, all through a SaaS solution, to regain access and functionality to IT infrastructure after a disaster1. DRaaS can help the organization to prioritize its core operations by:

Reducing the need for provisioning and maintaining its own off-site disaster recovery environment, which can be costly, complex, and resource-intensive12

Enabling the organization to continue running its applications from the service provider’s cloud or hybrid cloud environment instead of from the disaster-affected physical servers, which can minimize the downtime, data loss, and business disruption12

Providing the organization with flexible and scalable deployment options, such as on-demand, pay-per-use, or subscription-based models, that can meet its changing business needs and budget12

Leveraging the expertise, experience, and best practices of the service provider, who can handle the disaster recovery planning, testing, and execution, and ensure compliance with the relevant standards and regulations12
