NO.14 In SAP Web IDE, you rename a dimension calculation view that is used by a cube calculation view. You do NOT use the option to rename the runtime view and adjust the reference. Afterward, you perform the following build operations:Build the dimension calculation view as a single object.Build the entire SAP HANA database module.What is the outcome of the build operations?

The first build is successful.The second build is successful.

The first build fails.The second build fails.

The first build is successful.The second build fails.

The first build fails.The second build is successful.

NO.15 Which of the following approaches might improve the performance of joins in a CUBE calculation view?Note:
There are 2 correct answers to this question.

Use an inner join

Limit the number of joined columns

Specify the join cardinality

Define join direction in a full outer join

NO.16 Why do you use the Hidden Columns checkbox in the semantics node of your calculation view?Note: There are 2 correct answers to this question.

To ensure specific columns are NOT exposed to the reporting tool

To avoid exposing sensitive columns when defining calculated columns

To prevent passing columns in stacked calculation views

To remove a column that is also used as a Label column

NO.17 You want to map an input parameter of calculation view A to an input parameter of calculation view B using the parameter mapping feature in the calculation view editor. However, the input parameters of calculation view B are not proposed as source parameters.What might be the reason for this?

You selected the wrong parameter mapping TYPE.

Your source calculation view is of type DIMENSION.

The names of the input parameters do not match.

You already mapped the input parameters in another calculation view.

NO.18 Which of the following are warm data tier solutions?Note: There are 3 correct answers to this question.

Extension Node

Persistent memory

Native Storage Extension

Dynamic Tiering

Active / active read-enabled mode

NO.19 You import a project that includes an SAP HANA database (HDB) module to your workspace. You need to create a calculation view that uses data from a table located in an external schema within the same local database.Which of the following items do you need?Note: There are 2 correct answers to this question.

Authorization

Synonym

SQL view

Remote source

NO.20 You created a table and inserted data in it using SQL statements inside the SAP HANA Deployment Infrastructure (HDI) container of your project. You add this table as a data source to a calculation view and try to build it.What do you observe in the SAP HANA database container?

The build fails and the table is dropped.

The build fails and the table is not dropped.

The build is successful and the data preview returns expected data.

The build is successful but the data preview returns an error message.

NO.21 A calculation view consumes the data sources shown in the graphic. You want to identify which companies sold products in January AND February.

What is the optimal way to do this?

Use a union node.

Use a minus node.

Use an intersect node.

Use an aggregation node.

NO.22 You created a calculation view that combines two tables in a join node. To improve the runtime of your calculation view, you use a referential join to prune data sources.How do you check if pruning occurs?Note:
There are 2 correct answers to this question.

Use the SQL Analyzer to identify the tables used

Enable Debug Query mode to identify the columns used

Explore the number of used columns in the Performance Analysis mode

Preview the data results in the calculation view

NO.23 Why would you implement active / active read-enabled mode?

To provide offline access to data

To synchronize query results with operational data

To enhance security for data access

To improve query performance

NO.24 You are building a new calculation view A that uses calculation view B, as shown in the diagram. When you preview the calculation view A, the Account Number is not masked.

What could be the reason?

You previewed the data with the technical user in SAP Web IDE for SAP HANA.

You did not define masking in calculation view A.

The UNMASKED privilege for calculation view A has been granted.

Analytic privilege _SYS_BI_CP_ALL has been assigned.

NO.25 You have configured static cache for your calculation view and run a query against it, but the cache results are not being used.What might be the reason for this?

You did not define any columns in the cache setting.

The cache data retention period has expired.

The query requests only a subset of the cached results.

You did not define a filter in the cache setting.

NO.26 What are some best practices when developing calculation views?Note: There are 2 correct answers to this question.

Include all data flow logic within one calculation view.

Model star schemas using a sequence of join nodes.

Avoid defining joins on calculated columns.

Aggregate at the lowest possible node.

NO.27 Why would you partition a table in an SAP HANA Cloud database?Note: There are 2 correct answers to this question.

To improve response time when multiple users access the same table

To overcome the 2 billion record limit

To improve data replication performance on large row tables

To improve query performance when accessing large column tables

NO.28 When modeling in the SAP Web IDE for SAP HANA, which object do you build to provide access to tables in external schemas?

Virtual Table

Synonym

Association

Alias

NO.29 What are the limitations of using a full outer join in a star join node?Note: There are 2 correct answers to this question.

It must appear in the last DIMENSION in the star join node.

It CANNOT be mixed in the same star join node with other join types.

Only one column can be included in the join condition.

It is restricted to one DIMENSION in a star join node.

NO.30 You set the Null Handling property for an attribute but do not set a default value.What is displayed when null values are found in a column of data type NVARCHAR?

“?”

“Null”

“0”

NO.31 Why does SAP issue warnings about the use of imperative or procedural SQLScript statements?

They could modify the database.

They call multiple processing engines.

They introduce potential security risks.

They can limit parallelization of query execution.
