In DRP planning, which approach describes keeping services available by operating across multiple sites to minimize downtime?

• A. Archiving
• B. Network clustering
• C. Site mirroring
• D. Active/Active

Answer: (D)

Maintaining service availability by running workloads across multiple sites is about high availability in disaster recovery planning. In an Active/Active setup, production services are live at more than one site simultaneously, with data replication between them. Because both sites are handling traffic, if one site experiences an issue, the other can continue serving requests with little to no downtime, keeping services available. This approach requires reliable data replication (synchronous or near-synchronous, or well-tuned asynchronous), load balancing to distribute traffic, and coordinated failover processes. It’s designed to minimize downtime by not relying on a single location. Archiving focuses on long-term data preservation and isn’t about keeping services online. Network clustering usually centers on coordinating multiple nodes within or across locations for high availability, but it isn’t inherently about running live workloads across separate sites to the same extent. Site mirroring creates a backup site that mirrors the primary but may not be actively handling traffic at all times, whereas Active/Active keeps multiple sites actively serving users.
