SAP Certified Associate - Data Engineer - SAP HANA Sample Questions (Q21-Q26):
NEW QUESTION # 21
You implement a referential join between Table A and Table B, but when you query the calculation view, Table B is not pruned. What could be the problem? Note: There are 2 correct answers to this question.
- A. The Country column is requested.
- B. Join cardinality is set: 1.
- C. The Keep flag is activated for the Customer column.
- D. Integrity constraint is set to RIGHT.
Answer: C,D
Explanation:
If Table B is not pruned in a referential join, the possible issues could be:
* C. The Keep flag is activated for the Customer column: This prevents pruning by forcing the inclusion of the column in query execution.
* D. Integrity constraint is set to RIGHT: This setting implies that Table B data must always be considered in the join, disabling pruning.
Pruning depends on join conditions and flags; ensuring no unnecessary constraints is essential for proper optimization.

NEW QUESTION # 24
You combine two tables in a join node using multiple columns in each table.
Why do you enable the dynamic join option? Note: There are 2 correct answers to this question.
- A. To force the calculation at the relevant level of granularity, even if this level is not the grouping level defined by the query
- B. To ensure that the join execution uses only the join columns requested in the query
- C. To allow data analysis at different levels of granularity with the same calculation view
- D. To ensure that the aggregation always happens after the join execution
Answer: B,C
Explanation:
TheDynamic Joinoption in SAP HANA calculation views enables flexibility when joining tables with multiple columns. The reasons for enabling it include:
* B. To allow data analysis at different levels of granularity with the same calculation view:
Dynamic joins adjust to the query's granularity requirements, enabling analysis at various levels without redesigning the calculation view.
* D. To ensure that the join execution uses only the join columns requested in the query: This ensures efficient execution by only processing the relevant columns, reducing unnecessary computations.
NEW QUESTION # 25
