Which of the following is NOT a characteristic of the SAP HANA Multiple Database Container (MDC) system?

The correct answer identifies that multiple databases in an SAP HANA Multiple Database Container (MDC) system do not require separate installations. In an MDC setup, multiple tenant databases are housed within a single HANA database instance, allowing for efficient management and resource utilization. This means that operational overhead is reduced because the administrative and infrastructural setup is consolidated rather than duplicated.

In contrast, each tenant database benefits from isolation. They operate independently, which ensures that activities in one tenant do not impact the performance or data security of others. This isolation is a vital aspect of MDC’s architecture, allowing customization and unique configurations for each tenant database without interference.

The Name Server's role in facilitating operations, including communication between the various components of the system, provides essential functionality by directing queries to the correct tenant databases and managing their interactions with the index server.

Thus, all other options highlight characteristics inherent to the MDC framework, while the notion that multiple databases need separate installations contradicts the fundamental design of the MDC system, where central installation is a key feature.
