Which replication model is used to replicate snapshots to one or more clusters?

1. Off-prem replication

2. On-prem replication

3. Remote replication

4. Local replication

The correct answer is: Remote replication

The replication model used to replicate snapshots to one or more clusters is remote replication. This feature is designed to ensure data protection and business continuity by enabling users to create and manage snapshots of their virtual machines and replicating these snapshots to other cluster locations, whether they are in separate geographical locations or different data centers. This is crucial for disaster recovery and enhances the resilience of data management. Remote replication allows for asynchronous data transfer, meaning that data can be sent to the target cluster without requiring immediate acknowledgment, thus promoting efficient use of bandwidth and minimizing the impact on operational performance. In scenarios where organizations need to maintain up-to-date backups or disaster recovery options, remote replication is a preferred solution, ensuring that data is kept safe and accessible across different sites. Other models such as on-prem replication and local replication focus on snapshots and data that remain within a single cluster or site, which does not support the need for multi-cluster management and geographic redundancy. Off-prem replication can imply a different structure or focus, potentially related to external cloud backups or services rather than the internal clustering dynamics that remote replication addresses.
