    Which technology uses trigger-based replication?

    • A.

      Test Data Migration Server and Near Zero Downtime

    • B.

      ABAP extractors

    • C.

      Trex Engine and slandered SQL database replication

    • D.

      None of the above

    Correct Answer

    Which driver is required for the connection between HANA and BOBJ explorer?

    • A.

      JDBC

    • B.

      ODBC

    • C.

      OLTP

    • D.

      OLAP

    Correct Answer
    A. JDBC
    Explanation
    JDBC (Java Database Connectivity) is the correct driver required for the connection between HANA and BOBJ explorer. JDBC is a Java API that allows Java programs to connect to and interact with databases. In this case, it enables the connection between HANA (a database management system) and BOBJ explorer (a business intelligence tool). JDBC provides a standard set of methods for accessing and manipulating the database, making it the suitable driver for this connection. ODBC (Open Database Connectivity) is a different driver used for connecting to databases from various programming languages, but it is not the correct driver in this scenario.

By having both components installed, the system can effectively collect and transmit the required data for generating Early Watch Alerts.

    Rate this question:

  • 36. 

     Storage must be shared by SAP HANA nodes in a high availability scenario?

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In a high availability scenario, where multiple SAP HANA nodes are used, it is important for the storage to be shared among these nodes. This allows for data redundancy and ensures that if one node fails, another node can take over seamlessly without any data loss. By sharing the storage, the nodes can access the same data and maintain consistency, providing uninterrupted service to users. Therefore, the statement "Storage must be shared by SAP HANA nodes in a high availability scenario" is true.
