A converged database can reduce operational complexity because multiple data models and workload types can use a common database platform with a more consistent approach to security, upgrades, patching, and maintenance . The uploaded question source explicitly identifies option C. Oracle documentation states that Oracle AI Database is a converged, multimodel database and specifically highlights a common approach for security, upgrades, patching, and maintenance.

With separate point-solution databases, organizations may need distinct administrator skill sets, identity configurations, encryption mechanisms, backup procedures, monitoring systems, patch schedules, and replication pipelines. Consolidating appropriate workloads onto a converged database can remove portions of that duplicated operational footprint while allowing relational, JSON, graph, spatial, vector, and other capabilities to work together.

However, convergence does not mean security policies can stop being reviewed. Governance remains necessary. It also does not require every workload to use an identical physical schema or application-access mechanism; Oracle supports multiple data models and APIs precisely because applications have different access requirements.

Option D describes a disadvantage of fragmented point solutions: separate databases frequently introduce synchronization processes. The converged architecture is intended to reduce, rather than require, such duplication.
