NO.40 You developed a multi-target application that contains only a database module. Which environment are the runtime objects created in? Please choose the correct answer.

Java Runtime Environment (JRE)

SAP HANA Runtime Tools (HRTT)

SAP Web IDE for SAP HANA

HANA Deployment Infrastructure Container

A multi-target application (MTA) is a single application that consists of multiple modules that are developed using different technologies and designed to run on different target runtime environments. A database module is a module that contains database artifacts, such as tables, views, procedures, or functions, that are deployed to a SAP HANA database. A HANA Deployment Infrastructure (HDI) container is a logical grouping of database objects that are isolated from other containers and schemas in the same database. An HDI container has its own technical user, roles, and privileges, and can be accessed only through a service binding. When a database module is built, the SAP Web IDE for SAP HANA or the SAP Business Application Studio automatically creates an HDI container and binds it as a resource to the database module. It also creates the runtime objects, such as physical tables or views, in the schema associated with the HDI container. Therefore, the runtime objects of a database module are created in the HDI container, which is the correct answer. The other options are incorrect because they are not the environments where the runtime objects of a database module are created. The Java Runtime Environment (JRE) is a software environment that provides the minimum requirements for executing a Java application. The SAP HANA Runtime Tools (HRTT) are a set of tools that enable developers to create, run, and debug SAP HANA native applications in Eclipse. The SAP Web IDE for SAP HANA is a web-based development environment that supports the development of MTA projects and modules. References:

NO.45 Which Git command do you use to consolidate all changes from one branch with another branch using a single commit? Please choose the correct answer.

Commit

Rebase

Merge

Push

The Git command that you use to consolidate all changes from one branch with another branch using a single commit is merge. The merge command is used to integrate changes from another branch into the current branch. The target of this integration (i.e. the branch that receives changes) is always the currently checked out HEAD branch. The merge command can create a merge commit, which is a special commit that has two or more parent commits and records the result of the merge. Alternatively, the merge command can also perform a fast-forward merge, which is a simple update of the HEAD pointer without creating a new commit, if the current branch is an ancestor of the other branch.
For example, suppose you have two branches, master and feature, and you want to consolidate all changes from feature into master using a single commit. You can use the following commands:
git checkout master # switch to the master branch git merge feature # merge the feature branch into the master branch This will create a merge commit on the master branch that has two parents: the previous tip of the master branch and the tip of the feature branch. The merge commit will contain all the changes from the feature branch as well as the changes from the master branch.
The following Git commands are not used to consolidate all changes from one branch with another branch using a single commit, but for other purposes:
* Commit: The commit command is used to create a new commit on the current branch that records the changes made in the working tree and the index. The commit command does not integrate changes from another branch, but only from the local repository.
* Rebase: The rebase command is used to reapply a series of commits from one branch on top of another branch. The rebase command does not create a single commit, but rather modifies the history of the current branch by rewriting the commits and changing their parent commits. The rebase command can be used to achieve a linear history, but it can also cause conflicts and inconsistencies if used on public branches.
* Push: The push command is used to transfer commits from the local repository to a remote repository.
The push command does not integrate changes from another branch, but only from the local repository to the remote repository. The push command can also update the remote branch pointers to reflect the
* transferred commits.

Association

NO.48 How do you debug a Node.js module in SAP Web IDE for SAP HANA? Please choose the correct answer.

Set the enabled parameter to true in the section debugger of the xsengine.ini file.

Add the sap.hana .xs.debugger::Debugger role to the HDI Container’s #RT User.

Start the debugger from the XS command line interface and run the program in SAP Web IDE for SAP HANA.

Attach the debugger to the application in the SAP Web IDE for SAP HANA.

NO.49 What are the nodes where filter expressions can be used in a calculation view? There are 2 correct answers to this question.

Aggregation

Star join

Union

Rank

Filter expressions can be used in a calculation view to restrict or modify the data that is displayed or processed by the view. Filter expressions can be used in the following nodes of a calculation view12:
* Aggregation: An aggregation node is a node that applies aggregation functions, such as sum, count, or average, to the data that is passed from the previous node. Filter expressions can be used in an aggregation node to filter the data before or after the aggregation, or to define the aggregation level or the measure attributes. For example, you can use a filter expression to show only the sales data for a specific region or product category, or to calculate the average revenue per customer.
* Union: A union node is a node that combines the data from two or more nodes that have the same structure and data types. Filter expressions can be used in a union node to filter the data from each input node, or to filter the data from the output node. For example, you can use a filter expression to exclude the duplicate rows from the union result, or to show only the data that matches a certain condition from each input node.
The other options are not correct because filter expressions cannot be used in these nodes of a calculation view. A star join node is a node that joins a fact table with one or more dimension tables, based on the common key attributes. A star join node does not support filter expressions, but it supports input parameters, which are variables that can be used to filter the data at runtime. A rank node is a node that ranks the data according to a specified order and criteria. A rank node does not support filter expressions, but it supports rank filters, which are conditions that can be used to limit the number or percentage of rows in the rank result.

NO.52 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.
