* A. Rank: This node type is only available for graphical modeling of SAP HANA HDI Calculation Views(XS Advanced), but not for SAP HANA Calculation Views(XS Classic). It allows you to rank the data based on a measure and a ranking rule12.

* D. Graph: This node type is only available for graphical modeling of SAP HANA HDI Calculation Views(XS Advanced), but not for SAP HANA Calculation Views(XS Classic). It allows you to model graph data and perform graph operations such as shortest path, neighborhood search, and pattern matching13.

* A. Use fewer drill-down characteristics in the initial view: This can improve the query performance by reducing the amount of data that needs to be transferred and displayed at the start of the query execution. The user can drill down to more details later if needed1.

* D. Use mandatory characteristic value variables: This can improve the query performance by restricting the data selection to a smaller set of values that are relevant for the user. The user can also change the variable values later if needed1.

* E. Use include functions in the restricted key figures: This can improve the query performance by avoiding unnecessary calculations and aggregations that are done when using exclude functions. Include functions are also more efficient than selections or restricted key figures when filtering data1.
