NEW QUESTION 46
Which keywords do you use to define an OData association? There are 3 correct answers to this question.

JOIN

DEPENDENT

UNION

MULTIPLICITY

PRINCIPAL

NEW QUESTION 47
In an SQL Script procedure, which feature do you use to initialize IN/OUT table parameters? Please choose the correct answer.

IS_EMPTY

DEFAULT EMPTY

DEFAULT

SET

According to the SAP HANA Developer Guide, you can use the DEFAULT EMPTY clause to initialize IN/OUT table parameters in an SQL Script procedure. This clause specifies that the table parameter is initially empty when the procedure is called, and that the caller can pass an empty table or no table at all. This is useful when you want to use the table parameter as a temporary table inside the procedure, and return the result to the caller. For example, PROCEDURE proc1 (IN/OUT tab1 TABLE(col1 INT, col2 VARCHAR(10)) DEFAULT EMPTY) … The other options are incorrect, because:
* IS_EMPTY is a function that returns a boolean value indicating whether a table is empty or not. It is not a clause that can be used to initialize table parameters.
* DEFAULT is a clause that can be used to assign a default value to scalar parameters, not table parameters.
* SET is a statement that can be used to assign values to variables or parameters, not a clause that can be used to initialize table parameters.

NEW QUESTION 48
Why do you use associations in your persistence model for SAP HANA extended application services, advanced model (XS advanced)? Please choose the correct answer.

To enforce database-level constraints

To define the relationships between contexts and views

To define multiplicity and key of an entity relation

To set relationships between multiple contexts

NEW QUESTION 49
What are the issue categories that SQL Script Code Analyser scans for? There are 3 correct answers to this question.

Performance

Privileges

Security

Business logic

Consistency

The SQL Script Code Analyser is a tool that scans SQL Script code for potential issues and provides suggestions for improvement. The tool can be accessed from the SAP Web IDE for SAP HANA or from the SAP HANA database explorer. The tool scans for issues in the following categories:
* Performance: This category covers issues that may affect the execution time or resource consumption of the SQL Script code, such as inefficient joins, missing indexes, unnecessary data transfers, etc. The tool provides recommendations for optimizing the code, such as using parallel processing, avoiding nested loops, using table variables, etc.
* Security: This category covers issues that may expose the SQL Script code to security risks, such as SQL injection, privilege escalation, data leakage, etc. The tool provides recommendations for securing the code, such as using parameterized queries, escaping literals, applying proper authorization checks, etc.
* Consistency: This category covers issues that may affect the readability, maintainability, or portability of the SQL Script code, such as coding style, naming conventions, documentation, compatibility, etc.
* The tool provides recommendations for improving the code quality, such as using consistent indentation, avoiding hard-coded values, adding comments, following best practices, etc.
The other options are incorrect because privileges and business logic are not issue categories that the SQL Script Code Analyser scans for. Privileges are handled by the SAP HANA Deployment Infrastructure framework, which automatically grants the necessary privileges to the technical users and roles that access the HDI container objects. Business logic is the domain-specific logic that defines the functionality and behavior of the SQL Script code, and it is not within the scope of the tool to verify or validate it. References:

NEW QUESTION 50
You need to create a native SAP HANA application that fully leverages the SAP HANA platform. How do you implement data-intensive calculations?
Please choose the correct answer.

Push the calculations onto the application layer.

Push the calculations onto the database layer

Push the calculations onto the presentation layer.

Distribute calculations between application layer and presentation layer.

To create a native SAP HANA application that fully leverages the SAP HANA platform, you should implement data-intensive calculations on the database layer, using SQLScript or calculation views. SQLScript is a scripting language that allows you to write stored procedures, functions, and triggers that perform complex calculations and data transformations on the SAP HANA database. Calculation views are graphical or scripted views that define data models based on tables, views, or other calculation views, and apply filters, joins, aggregations, and other operations on the data. By pushing the calculations onto the database layer, you can take advantage of the in-memory processing, parallelization, and optimization capabilities of SAP HANA, and reduce the data transfer and network latency between the application layer and the database layer123.
The other options are not correct because they do not fully leverage the SAP HANA platform, and they may result in poor performance, high resource consumption, and increased complexity. Pushing the calculations onto the application layer means that you use a programming language, such as Java or Node.js, to perform the calculations on the application server, which may not be as efficient or scalable as the database server. Pushing the calculations onto the presentation layer means that you use a UI framework, such as SAPUI5 or SAP Fiori, to perform the calculations on the client device, such as a browser or a mobile device, which may not have enough processing power or memory to handle large or complex data sets. Distributing the calculations between the application layer and the presentation layer means that you split the calculations into different parts and execute them on different layers, which may introduce inconsistency, redundancy, and dependency issues.

NEW QUESTION 51
Which OData capacity do you use when you need to restrict the number or selection of exposed columns?
Please choose the correct answer.

Parameter entity sets

Aggregation

Key specification

Property projection

Property projection is an OData capability that allows you to restrict the number or selection of exposed columns in an OData service. Property projection is achieved by using the $select query option, which specifies a subset of properties to be included in the response. The $select query option can be applied to a single entity, a collection of entities, or a complex type. Property projection can be used to reduce the payload size and improve the performance of the OData service.
For example, suppose you have an OData service that exposes a Products entity set with the following properties: ID, Name, Category, Price, and Description. If you want to restrict the number or selection of exposed columns to only ID and Name, you can use the $select query option as follows:
GET /Products?$select=ID,Name
The result is: { “@odata.context”: “$metadata#Products(ID,Name)”, “value”: [ { “ID”: 1, “Name”: “Laptop” }, { “ID”: 2, “Name”: “Mouse” }, { “ID”: 3, “Name”: “Keyboard” } ] }
The following OData capabilities are not used to restrict the number or selection of exposed columns, but for other purposes:
* Parameter entity sets: Parameter entity sets are a way to define entity sets that require one or more parameters to be specified in the request. Parameter entity sets can be used to implement function imports or actions that return a collection of entities. Parameter entity sets can also be used to filter or sort the results based on the parameters.
* Aggregation: Aggregation is a way to apply aggregate functions, such as sum, count, min, max, or average, to the properties of an entity set or a complex type. Aggregation can be used to perform calculations or analysis on the data. Aggregation is achieved by using the $apply query option, which specifies a transformation pipeline with various operators, such as groupby, aggregate, filter, or order by.
* Key specification: Key specification is a way to define the key properties of an entity type, which uniquely identify an entity instance within an entity set. Key specification is part of the entity type definition in the metadata document of the OData service. Key specification can be used to retrieve a single entity by its key values.

NEW QUESTION 57
From which tool can you run the XS command line? Please choose the correct answer.

Local operating system shell

SAP HANA studio

SAP WeblDE for SAP HANA

SAP HANA cockpit

The XS command line is a tool that allows you to administer and manage the XS advanced runtime environment and the applications deployed on it. You can run the XS command line from the local operating system shell of your machine, as long as you have installed the XS CLI client package and added the bin folder to the PATH environment variable1. You can also run the XS command line from the SAP HANA system, where the XS advanced runtime is installed, by logging in as user XSA_ADMIN or <sid>adm2.
The other options, SAP HANA studio, SAP Web IDE for SAP HANA, and SAP HANA cockpit, are not tools that can run the XS command line. SAP HANA studio is an Eclipse-based tool that allows you to develop, model, and administer SAP HANA databases and applications, but it does not support XS advanced features3. SAP Web IDE for SAP HANA is a web-based tool that allows you to develop, test, and deploy SAP HANA applications using XS advanced features, but it does not provide a command line interface4. SAP HANA cockpit is a web-based tool that allows you to monitor and manage SAP HANA databases and applications, but it does not provide a command line interface either5.

NEW QUESTION 59
You configure an OData service for a transactional SAPUI5 application. What is the default data access behavior of the OData service? Please choose the correct answer.

Read: Yes Create: Yes Update: Yes Delete: Yes

Read: Yes Create: Yes Update: Yes Delete: No

Read: Yes, Create: No Update: Yes Delete: No

Read: Yes, Create: No Update: No Delete: No

To configure an OData service for a transactional SAPUI5 application, you need to use the SAP Cloud Application Programming Model (CAP) and the SAP Fiori Elements framework. The CAP provides a declarative and consistent way to define and expose data models and services as OData v4 endpoints. The SAP Fiori Elements framework provides generic UI templates and controllers that can consume OData v4 services and support CRUD (Create, Read, Update, Delete) operations. The default data access behavior of the OData service is to allow all CRUD operations, unless you specify otherwise in the service definition or the annotations.
The other options are not correct because:
* B. Read: Yes Create: Yes Update: Yes Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Deletable annotation to false for the entity or the entity set in the service definition or the annotations.
* C. Read: Yes, Create: No Update: Yes Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Creatable annotation to false for the entity or the entity set in the service definition or the annotations.
* D. Read: Yes, Create: No Update: No Delete: No: This is not the default data access behavior of the OData service, but it can be achieved by setting the @Creatable and @Updatable annotations to false for the entity or the entity set in the service definition or the annotations.

NEW QUESTION 60
Which tool do you use to create a calculation view in a multi-target application? Please choose the correct answer.

SAP Web IDE for SAP HANA

SAP HANA database explorer

SAP HANA Web-based Development Workbench

SAP HANA studio

To create a calculation view in a multi-target application, you need to use the SAP Web IDE for SAP HANA, which is a web-based development environment that supports the full development lifecycle of SAP HANA applications. The SAP Web IDE for SAP HANA provides graphical and code-based editors for creating calculation views, as well as other database artifacts, such as tables, views, procedures, functions, and more.
You can also use the SAP Web IDE for SAP HANA to create and deploy multi-target applications, which are modular applications that consist of multiple components, such as database modules, Node.js modules, Java modules, HTML5 modules, etc. The other options are incorrect because the SAP HANA database explorer, the SAP HANA Web-based Development Workbench, and the SAP HANA studio do not support the creation of calculation views in a multi-target application. The SAP HANA database explorer is a web-based tool that allows you to browse, manage, and query SAP HANA databases, but not to create or edit database artifacts.
The SAP HANA Web-based Development Workbench is a deprecated tool that was used to create and edit SAP HANA XS classic applications, but not multi-target applications. The SAP HANA studio is a desktop tool that was used to create and edit SAP HANA native applications, but not multi-target applications.
