An administrator intends to configure a NearSync replication schedule with a 15-minute Recovery Point Objective (RPO) on a hybrid 3-node cluster. The current nodes in the cluster are configured with one SSD and four HDDs each. Which cost-effective modification is required to support this specific replication schedule?

NearSync replication on hybrid clusters requires a minimum of 2 SSDs per node to handle the metadata operations and provide sufficient performance for frequent snapshots. With only 1 SSD per node, the cluster cannot support NearSync's performance requirements. Adding a second SSD to each node is the most cost-effective solution that directly addresses the minimum hardware requirement for NearSync on hybrid configurations.

A. Replacing HDDs with NVMe is excessive and not cost-effective for this requirement.
B. Three nodes meet the minimum cluster size for NearSync replication.
C. Default CVM memory is sufficient for NearSync; increasing to 64GB is unnecessary.
