Most Effective Technique for Business Recovery

D.

The most effective technique for a Disaster Recovery Plan (DRP) to recover business as soon as possible would be "site mirroring" (option C).

Site mirroring is a technique where an exact replica of the production site is created, including servers, applications, and data. In the event of a disaster, the mirrored site can be activated and used as the primary site to ensure business continuity. Site mirroring helps to reduce downtime and minimize data loss by ensuring that data is consistently replicated in real-time or near real-time.

Archiving (option A) is not an effective technique for a DRP as it involves storing data in a separate location for long-term retention, rather than providing immediate access to data during a disaster.

Network clustering (option B) is a technique where multiple servers are interconnected to work together as a single system. While clustering can provide redundancy and failover capabilities, it may not be the most effective technique for a DRP as it does not necessarily replicate the entire production environment.

Active/Active (option D) is a technique where multiple data centers are actively processing data simultaneously, rather than as a backup or failover. While this technique can provide high availability and load balancing capabilities, it may not be the most effective technique for a DRP as it may not be cost-effective or practical for all organizations.

In summary, site mirroring is the most effective technique for a DRP as it provides a complete replica of the production environment, minimizing downtime and data loss.
