Which setting would allow for fast recovery in a hybrid cloud environment?

1. Implementing Async Replication

2. Utilizing a single protection domain

3. Configuring optimized indirect access

4. Setting up NearSync

The correct answer is: Setting up NearSync

Setting up NearSync is designed to facilitate rapid recovery in a hybrid cloud environment by enabling a near real-time replication of data. This solution minimizes data loss by frequently synchronizing data between the primary site and a secondary site. As a result, in the event of a failure or a disaster, recovery can be executed quickly with minimal data that is lost—often within mere seconds of the last synchronization point. NearSync allows for restoring applications and services with less downtime, which is crucial in maintaining business continuity. The key advantage here lies in the ability to consistently align data across sites, so that when a recovery is necessary, the system has the most up-to-date information available for restoration. In contrast, other options may not provide the same level of speed and efficiency in recovery. For example, asynchronous replication typically involves delays as data is sent in chunks at intervals rather than instantaneously, which could lead to more significant data loss during recovery. A single protection domain may simplify management but does not enhance recovery speed significantly compared to a NearSync setup. Meanwhile, optimized indirect access is more about improving performance and access to data rather than specifically enhancing recovery speeds.
