Thomas Gibson is a cloud security engineer who works in a multinational company. His organization wants to host critical elements of its applications; thus, if disaster strikes, applications can be restored quickly and completely. Moreover, his organization wants to achieve lower RTO and RPO values. Which of the following disaster recovery approach should be adopted by Thomas' organization?

Multi-Cloud Option
Suggested answer: A

Explanation:

The Warm Standby approach in disaster recovery is designed to achieve lower Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) values. This approach involves having a scaled-down version of a fully functional environment running at all times in the cloud. In the event of a disaster, the system can quickly switch over to the warm standby environment, which is already running and up-to-date, thus ensuring a quick and complete restoration of applications.

Here's how the Warm Standby approach works:

1.Prepared Environment: A duplicate of the production environment is running in the cloud, but at a reduced capacity.

1.Quick Activation: In case of a disaster, this environment can be quickly scaled up to handle the full production load.

1.Data Synchronization: Regular data synchronization ensures that the standby environment is always up-to-date, which contributes to a low RPO.

1.Reduced Downtime: Because the standby system is always running, the time to switch over is minimal, leading to a low RTO.

1.Cost-Efficiency: While more expensive than a cold standby, it is more cost-effective than a hot standby, balancing cost with readiness.
