How does virtualization enhance disaster recovery in data centers?

• A. By increasing physical hardware
• B. Freeing up memory resources
• C. Supporting live migration
• D. Reducing backup times

Answer: (C)

Virtualization enhances disaster recovery in data centers primarily by supporting live migration. Live migration allows virtual machines to be moved from one physical server to another without any downtime. This capability is crucial during a disaster recovery scenario because it enables the continuous operation of applications and services, even when there are hardware failures or the need to perform maintenance. By utilizing live migration, data centers can redistribute workloads across available resources in real-time, which not only ensures high availability of services but also minimizes the impact on users. This seamless transition helps maintain business continuity and enhances overall resilience, which is vital when recovering from a disaster. While other options may seem relevant to performance and efficiency, they do not specifically address how virtualization improves the disaster recovery process in terms of maintaining uptime and service availability during critical situations. Thus, the ability to support live migration stands out as a key feature that directly contributes to effective disaster recovery strategies.
