    Rate this question:

  • 2. 

    Regarding Info Cubes : The F Table is optimized for loading data and the E table is optimized for data Requests

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The given statement is true. In SAP BW, an InfoCube is a data storage structure that holds data for reporting purposes. The F Table, also known as the Fact Table, is optimized for loading data into the InfoCube. It stores the actual data values along with key figures and dimensions. On the other hand, the E Table, also known as the Extended Table, is optimized for data requests. It contains aggregated data that is pre-calculated and summarized for faster retrieval during reporting. Therefore, the F Table is designed for efficient data loading, while the E Table is designed for efficient data retrieval.

    Rate this question:

  • 3. 

    On activation of info Cubes the "D" table (/BIC/D...) is generated for each Dimension 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When info Cubes are activated, a table called "D" is generated for each dimension. This table is used to store the dimension data associated with the info Cube. Therefore, the statement "On activation of info Cubes the 'D' table is generated for each dimension" is true.

    Rate this question:

  • 4. 

    The dimension tables contains the data for each Characteristic with a DIM ID as the primary key of the Table

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The explanation for the given correct answer, which is False, is that dimension tables do not necessarily need to have a DIM ID as the primary key. While it is common for dimension tables to have a primary key, it can be any other suitable attribute or combination of attributes that uniquely identifies each row in the table. The primary key could be a natural key, such as a customer ID or a product code, or it could be a surrogate key generated specifically for the dimension table. Therefore, the statement that all dimension tables have a DIM ID as the primary key is incorrect.

    Rate this question:

  • 5. 

    In a ________ all descriptive attributes are located in other dimensions

    • A.

      Degenerated Dimension

    • B.

      Optimized Dimension

    • C.

      Line item Dimension

    • D.

      Non-Attribute Dimension

    Correct Answer(s)
    A. Degenerated Dimension
    C. Line item Dimension
    Explanation
    A degenerated dimension is a dimension that is created from a fact table's attribute, such as an order number or transaction ID. In this case, all descriptive attributes are located in other dimensions, and the degenerated dimension only contains a single attribute. A line item dimension, on the other hand, is used to store details about individual line items in a transaction, such as product name, quantity, and price. Therefore, the correct answer is Degenerated Dimension, Line item Dimension.

    Rate this question:

  • 6. 

    The setting _________ is used to change the method for dimention indexing in Oracle DB Only

    • A.

      Optimized Indexing

    • B.

      Low Indexing

    • C.

      High Cardinality

    Correct Answer
    C. High Cardinality
    Explanation
    High Cardinality is the correct answer because it refers to a setting used to change the method for dimension indexing in Oracle DB Only. High Cardinality indexing is used when the dimension contains a large number of distinct values, allowing for more efficient indexing and query performance. This setting is particularly useful in scenarios where the dimension has a high level of uniqueness and variability in its values.

    Rate this question:

  • 7. 

    Characteristics with an N:M relationship can be combined in the same dimension if the Maximum number of records are clearly defined and the Cartesian product of the Characteristic results only in a small dimension table 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Characteristics with an N:M relationship can be combined in the same dimension if the maximum number of records are clearly defined and the Cartesian product of the characteristic results only in a small dimension table. This means that if the number of records is limited and the resulting dimension table is not too large, it is possible to combine the characteristics. This allows for more efficient and organized data representation, making it easier to analyze and interpret the information.

    Rate this question:

  • 8. 

    The MultiProvider does not contain any data itself. Its data comes exclusively from the InfoProviders on which it is based, which are grouped together in a join operation.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The MultiProvider does not contain any data itself, but rather acts as a virtual InfoProvider that combines data from multiple InfoProviders. It does not perform a join operation to retrieve data from the underlying InfoProviders. Instead, it uses a union operation to aggregate data from the different InfoProviders. Therefore, the statement that the data in a MultiProvider comes exclusively from the InfoProviders on which it is based is false.

    Rate this question:

  • 9. 

    A MultiProvider can be made up of various combinations of the following InfoProviders: InfoCube, DataStore object, InfoObject, InfoSet, VirtualProvider, and aggregation level.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A MultiProvider is a type of InfoProvider in SAP BW that allows combining data from different InfoProviders such as InfoCube, DataStore object, InfoObject, InfoSet, VirtualProvider, and aggregation level. This allows users to create a single unified view of data from multiple sources, enabling more comprehensive reporting and analysis. Therefore, the given statement is true.

    Rate this question:

  • 10. 

    Since MultiProviders do not save any data, performance aspects do not affect the way dimensions of the MultiProvider are modeled.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because MultiProviders in SAP BW do not store any data themselves. They are virtual objects that combine data from different InfoProviders. As a result, the modeling of dimensions in a MultiProvider does not have any impact on performance since the data is not stored within the MultiProvider itself. The performance aspects are instead determined by the underlying InfoProviders that contain the actual data.

    Rate this question:

  • 11. 

    The MultiProvider also optimizes read access since _________ subqueries are executed on every InfoProvider involved in the MultiProvider.

    • A.

      Optimized

    • B.

      Parallel

    • C.

      Smaller

    Correct Answer
    B. Parallel
    Explanation
    The MultiProvider optimizes read access by executing parallel subqueries on every InfoProvider involved. This means that instead of sequentially accessing each InfoProvider, the MultiProvider can simultaneously access multiple InfoProviders, improving the efficiency and speed of the read operations.

    Rate this question:

  • 12. 

    You can include the __________ characteristic in the query selection criteria and specify the basic InfoProvider against which the query is executed.

    • B.

      0INFOPROVIDER

    • C.

      0INFOPROV

    • D.

      0SUBSET

    Correct Answer
    C. 0INFOPROV
    Explanation
    In a query, you can include the "INFOPROV" characteristic in the query selection criteria to specify the basic InfoProvider against which the query is executed. This allows you to filter the data based on the specific InfoProvider you want to retrieve information from.

    Rate this question:

  • 13. 

    Do not use more than one InfoCube with non-cumulative key figures in a MultiProvider, otherwise the numbers in the query may be incorrect.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Using multiple InfoCubes with non-cumulative key figures in a MultiProvider can lead to incorrect numbers in the query. This is because non-cumulative key figures do not aggregate correctly across multiple InfoCubes. Therefore, it is recommended to avoid using more than one InfoCube with non-cumulative key figures in a MultiProvider to ensure accurate results in the query.

    Rate this question:

  • 14. 

    The tools of the OLAP for performance optimization (such as caching and aggregation) can be used for a MultiProvider even if the InfoProviders involved does not support these tools.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because the tools of OLAP for performance optimization, such as caching and aggregation, cannot be used for a MultiProvider if the InfoProviders involved do not support these tools. In order to utilize these tools, the InfoProviders must have the necessary capabilities and functionality.

    Rate this question:

  • 15. 

    Parallel processing is not possible with InfoSets.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    InfoSets are a feature in SAP BW (Business Warehouse) that allow for data extraction and reporting. However, InfoSets do not support parallel processing. Parallel processing refers to the ability to execute multiple tasks simultaneously, which can improve performance and efficiency. Since InfoSets do not have this capability, the statement that parallel processing is not possible with InfoSets is true.

    Rate this question:

    Infosets can be based on which of the following Info providers.

    • A.

      Data Store Object

    • B.

      Master data Charateristics

    • C.

      Multiprovidors

    • D.

      Infosource

    • E.

      Infocubes

    Correct Answer(s)
    A. Data Store Object
    B. Master data Charateristics
    E. Infocubes
    Explanation
    Infosets can be based on Data Store Objects, Master Data Characteristics, and Infocubes. Infosets are virtual InfoProviders that allow users to combine data from different sources and create a unified view for reporting and analysis. Data Store Objects store detailed data at a granular level, Master Data Characteristics provide information about key attributes, and Infocubes store aggregated data for reporting purposes. By including these three InfoProviders, users can create comprehensive and meaningful Infosets that meet their reporting requirements.

    Rate this question:

  • 17. 

    Wich of the following are joins supported by InfoSets

    • A.

      Temporal Join

    • B.

      Union

    • C.

      Inner join

    • D.

      Outer join

    • E.

      Key join

    Correct Answer(s)
    A. Temporal Join
    C. Inner join
    D. Outer join
    Explanation
    InfoSets are used in SAP systems to define data sources for reporting purposes. They provide a way to combine data from different tables or views. Temporal Join, Inner Join, and Outer Join are all types of joins supported by InfoSets.

    A Temporal Join is used to join tables based on a time period, allowing for analysis of historical data.

    An Inner Join combines records from two tables based on a matching condition, resulting in only the matching records being included in the result set.

    An Outer Join includes all records from one table and the matching records from another table, even if there is no match.

    Key Join is not supported by InfoSets and therefore not included in the correct answer.

    Rate this question:

  • 18. 

    When creating an InfoSet from several characteristics, you can map transitive attributes and use these to report on master data

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When creating an InfoSet from several characteristics, it is possible to map transitive attributes. These transitive attributes can be used to report on master data. This means that the InfoSet can include additional attributes that are derived from the original characteristics, allowing for more comprehensive reporting and analysis. Therefore, the statement "When creating an InfoSet from several characteristics, you can map transitive attributes and use these to report on master data" is true.

    For InfoSets it is possible to define an InfoCube as a right operand of a left outer join.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    It is not possible to define an InfoCube as a right operand of a left outer join. In SAP BW, an InfoCube is a multi-dimensional data structure that stores consolidated and aggregated data for reporting and analysis. It cannot be used as a right operand in a join operation as it does not have the necessary characteristics and structure for joining with other tables or cubes.

    Rate this question:
