What feature allows SAP HANA to support a 3-tier scenario using Secure User Store?

The feature that allows SAP HANA to support a 3-tier scenario using a Secure User Store is high availability. High availability in SAP HANA ensures that both the database and its services are consistently accessible, minimizing downtime and enabling continuous operation. In a 3-tier architecture, which typically consists of the presentation layer (client), application layer (middleware), and database layer, high availability is crucial for enabling seamless access to the data by ensuring that application servers can reliably connect to the database layer without interruptions.

This supports the Secure User Store by maintaining the integrity and availability of user credentials and session management across the architecture, allowing for robust security while supporting all layers. The high availability feature allows multiple instances to work together, providing failover capabilities that ensure users can continuously access the application without encountering errors due to database failures. This underpins user authentication, session management, and other essential functions needed for a secure and stable environment in multi-layered applications.

In contrast, while the other options may provide important functionalities within SAP HANA, they do not specifically address the 3-tier architecture requirement in relation to the Secure User Store as effectively as high availability does.
