- B. A source file resource replicating synchronously from Site A to Site B and replicating asynchronously from Site A to Site C
- C. A source block resource replicating synchronously from Site A to Site B and replicating synchronously from Site A to Site C
- D. A source block resource replicating synchronously from Site A to Site B and replicating asynchronously from Site A to Site C
Answer: A
Explanation:
Explanation
Dell Unity XT MetroSync replication topology is a multi-site replication solution that allows you to replicate data synchronously between two or more Unity XT systems. In this topology, a source file resource is replicated synchronously from Site A to Site B, and also replicated synchronously from Site A to Site C. This means that data is written to the primary site and immediately replicated to the secondary site, ensuring that both sites have an exact copy of the data at all times. This type of topology is useful in cases where data loss is not acceptable and a zero RPO is needed. This topology ensures that the data is fully protected and that the environment is highly available, as in case of a primary site failure, the secondary site can take over.
