Choose the correct explanation for each product: SAP Business One SAP Business ByDesign SAP Business All-in-One SAP Business Suite.
It consists of a number of modular enterprise software products that support end-to-end company processes. It is part of the Business Process Platform (BPP). SAP Business Suite SAP ERP Operations SAP NetWeaver SAP ERP Corporate Services.
The Business Process Platform (BPP) is a prerequisite for the deployment of a service-oriented architecture (SOA) for business applications. It is composed of the following parts: (There are three correct answers) The SAP Business Suite, which provides ready-to-execute software for business processes Reusable enterprise services for use in composite applications SAP NetWeaver ABAP messaging channels User and process administration.
It is an open integration and application platform for all SAP applications and certain SAP partner applications. It supports open standards. It is interoperable with the most important technology standards such as Java 2 Platform, Java Enterprise Edition (Java EE), and Microsoft .NET. SAP NetWeaver SAP Customer Relationship Management (SAP CRM) SAP R/3 Enterprise The Internet Communication Manager (ICM).
SAP Enterprise Resource Planning (ERP) is a central application of the SAP Business Suite. The central software component of SAP ERP is: SAP ERP Central Component (SAP ECC) SAP R/3 SAP R/3 4.6C SAP R/2 SAP ERP Corporate Services (SAP CS).
It is not currently used as the technical basis for an SAP ECC system. However, other SAP NetWeaver components, such as SAP Process Integration (PI) and SAP Composition Environment (CE), already require this SAP NetWeaver release level. SAP NetWeaver AS 7.10 (or SAP NetWeaver 7.1) SAP NetWeaver AS 6.10 (or SAP NetWeaver 6.1) SAP R/3 Java application server.
With ..., new technologies based on highly scalable infrastructure were implemented to process HTTP requests directly from the Internet or to send them as HTTP client requests to the Internet. Before this, an Internet Transaction Server was required to deal with these requests. SAP Web AS 6.10 SAP Web AS 8.10 SAP R/3 SAP Enterprise Resource Planning (ERP).
The kernel uses the ... to directly handle HTTP requests, allowing for new web-based applications—for example, Business Server Pages (BSPs). Incoming web requests are received by the ..., which uses the URL to decide where to forward the request. Internet Communication Manager (ICM) HTTP Admin Tool SAP Product Lifecycle Management (SAP PLM) SAP ERP Corporate Services.
It is a platform that allows both ABAP and Java to exist and function within the same system. SAP NetWeaver server Software Deployment Manager (SDM) Java application server Internet Communication Manager (ICM).
Choose the correct option: Dispatcher/Java Dispatcher ABAP Work Processes/Java Server Work Processes ABAP Gateway ICM Software Deployment Manager (SDM).
ABAP Messaging Channels - Data objects with specific data types are allowed as messages. Messages that can be sent and received are: (There are three correct answers) Text strings Byte strings Content that can be serialized in accordance with fixed protocols. Helper classes are available for serializations and deserializations Boolean Data strings.
What is correct to say about ABAP messaging channels: (There are four correct answers) Are a method of communication between ABAP programs, via messages that can be used from SP03 Enable a new type of communication between AS ABAP programs, which goes beyond the limits of an application server Messages can be exchanged between any AS ABAP programs, including communication between different user sessions and application services Are implemented as repository objects that can be accessed in sender and receiver programs via an interface-based and class-based (API) Any data object can be sent by being serialized by the sender and deserialized by the receiver The length of messages that can be sent is currently restricted to approximately 15,000 bytes. Character strings are converted to the UTF-8 format.
What is correct to say about ABAP push channels: (There are two correct answers) ABAP push channels can be used only from SP02 and enable bidirectional communication with the Internet for ABAP programs using the WebSocket protocol Like HTTP, the WebSocket protocol, based on TCP, makes push communication possible This protocol reduces the number of connections between client and server ABAP push channels can be used to make AS ABAP into a WebSocket server for WebSocket clients.
Talking about an SAP NetWeaver Application Server, select the correct properties from an instance: (There are four correct answers) Always has exactly one dispatcher Starts when the dispatcher starts Requires at least two dialog work processes, but has at least a minimum number of work processes defined by the system Is also called the application server in the software-oriented view of the client server model Has at least one dispatcher, but the maximum number of dispatchers are defined by the system servel model Always has exactly one dialog work process.
Talking about an SAP NetWeaver Application Server, what is correct to say about instances: (There are three correct answers) Each instance runs on one dedicated physical server An instance is an administrative unit that combines SAP system components that provide one or more services The services provided by an instance are started or stopped together Each instance has its own memory buffer areas All running instances share the same memory buffer area.
The Kernel and Administration services component is... a runtime environment for ABAP applications that is hardware independent, operating system independent, and database independent. a method of communication between ABAP programs,via messages that can be used from SP02 a central application of the SAP Business Suite an open integration and application platform for all SAP applications.
The tasks of the kernel and administration services component are as follows: (There are five correct answers) Running applications User and process administration Database access Communication Control and administration of AS ABAP Push Channel Protocol maintenance Defines the elements for user interaction Connect a work process to a consumer.
The following definition talks about which component from kernel and administration services: All ABAP applications run on software processes (virtual machines) within this component. Running applications User and process administration Database access Communication Control and administration of AS ABAP.
The following definition talks about which component from kernel and administration services: This component is responsible for the tasks that usually belong to an operating system. Users log onto the SAP NetWeaver Application Server and run ABAP applications within it; they do not have direct contact with the actual operating system of the host. AS ABAP is the only user of the host operating system. Running applications User and process administration Database access Communication Control and administration of AS ABAP.
The following definition talks about which component from kernel and administration services: Each ABAP Application Server is linked to a database system consisting of a database management system (DBMS) and the database itself. The ABAP applications do not communicate directly with the database. Instead, they use administration services. As we will discuss shortly, these services handle the SAP table buffering on the application server, the translation from Open SQL to Native SQL for the database, and the management of SAP-specific concepts (for example, the client number or the structure of a cluster table). Running applications User and process administration Database access Communication Control and administration of AS ABAP.
The following definition talks about which component from kernel and administration services: ABAP applications can communicate both with other SAP systems and with external systems. It is also possible to access ABAP applications from external systems using a Business Application Programming Interface (BAPI) or a Remote Function Call (RFC). The services required for communication are all part of the kernel and administration services component. Running applications User and process administration Database access Communication Control and administration of AS ABAP.
The following definition talks about which component from kernel and administration services: This component contains programs that allow you to monitor and control the SAP NetWeaver Application Server while it is running and to change its runtime parameters. Running applications User and process administration Database access Communication Control and administration of AS ABAP.
Software-Oriented View - The classic configuration of an SAP system contains the following three software layers: (There are three correct answers) Database layer Application layer Presentation layer Communication layer Flow logic layer.
What is correct to say about the database layer: (There are four correct answers) It consists of a central database system made up of the database management system and the database itself The database contains the master data and transaction data for your ABAP application programs It also contains the control and customizing data for the application and the SAP NetWeaver Application Server and the ABAP application programs themselves The development objects (programs, screen definitions, menus, function modules, and so on) are all stored in a special part of the database known as the Repository It consists of one or more ABAP application servers and a message server It is the interface between the SAP system and its users.
What is correct to say about application layer: (There are four correct answers) The software components of the application layer of AS ABAP consist of one or more ABAP application servers and a message server Each application server contains a set of services used to run the SAP NetWeaver Application Server Theoretically, you only need one application server to run an SAP NetWeaver Application Server, but the services are normally distributed across more than one application server The message server allows for communication between the application servers The software components of the application layer of AS ABAP consist allways of more than one ABAP application servers and a message server It also contains the control and customizing data for the application and the SAP NetWeaver Application Server and the ABAP application programs themselves.
What is correct to say about the presentation layer: (There are three correct answers) It is the interface between the SAP system and its users It sends the user’s input to the application server and receives data for display from it While an SAP GUI component is running, it remains linked to a user’s terminal session in the AS ABAP It consists of one or more ABAP application servers and a message server It sends the user’s input to the database layer and receives data for display from it.
There are a number of benefits to the distribution of the SAP system over three layers: (There are two correct answers) It centralizes the system load leading to better system performance provides high scalability, because the software components can be distributed among different hardware virtually without restriction. In the presentation layer, you can meet increasing demand by installing additional ABAP application servers.
User oriented view - Choose the right options: (There ar two correct answers) All ABAP programs run on the ABAP application servers of AS ABAP (AS ABAP stack) The database layer of the multitier architecture of an ABAP-based SAP system is made up of all of the ABAP application servers These application servers execute ABAP applications and communicate with the presentation components, the database, and each other through the message server ABAP application server also contains a dispatcher, a gateway, and unshared memory.
What is correct to say about Work process: (There are two correct answers) are components that execute an application For a dialogwork process, each work process executes more than one dialog step simultaneously Each work process is linked to a memory area that contains the context of the executing application.This context contains the data for the application After the work process completes the dialog step, the link to the user and the program context is mantained.
What is correct to say about Dispatcher: (There are three correct answers) It provides the link between the work process and the user logged onto the application server It receives requests from an SAP GUI or web browser and directs the requests to a free work process Once the work process completes the dialog step, the resulting screen output is returned to the appropriate user before the link is released Its purpose is to communicate internally with other ABAP application servers Are components that execute an application.
It is the interface for the communication protocols of AS ABAP(RFC and CPI/C). Its purpose is to communicate internally with other ABAP application servers within this system, externally with other SAP systems, or externally with non-SAP systems. Gateway Work processes Dispatcher.
What is correct to say about ABAP application server: (There are four correct answers) All work processes use a common main memory area called general memory to save contexts or to locally buffer constant data Resources that work processes share or use (for example, programs and buffered table contents) are placed in shared memory Local buffering of data in the shared memory of the ABAP application server reduces the number of database reads required When you start an AS ABAP, each ABAP application server registers its work processes with the database layer and receives a single dedicated channel for each work process A work process can only make database changes within a single database logical unit of work (LUW) It is possible to change the work process registration while the system is running and also reassign a database channel from one work process to another.
Work process components: Screen processor ABAP processor Database interface.
There are two different ways of accessing SAP database tables using ABAP: Native SQL and Open SQL Oracle and DB2 access management MySQL and Oracle tools Native SQL and Free SQL.
What is correct to say about Open SQL: (There are three correct answers) Open SQL statements are a subset of standard SQL that is partially integrated in ABAP. These statements allow you to access data irrespective of the database system Open SQL consists of the Data Manipulation Language (DML), that allows you to read (SELECT) and change (INSERT, MODIFY, UPDATE, and DELETE) data The tasks of the Data Definition Language (DDL) and Data Control Language (DCL) are not integrated Open SQL goes beyond standard SQL to provide statements that, in conjunction with other ABAP constructions, can simplify or speed up database access It allows you to buffer certain tables on the ABAP application server, saving excessive database access.
Talking about buffer tables on the ABAP application server, what is correct to say: (There are two correct answers) The ABAP Processor is responsible for managing the buffer with the database. Database table buffers are stored totally in the working memory of the current work process In cases where the AS ABAP is distributed across more than one ABAP application server, the data in the various buffers is synchronized at set intervals by the buffer management. You must remember that the data in the buffer may not always be up to date. You should only use the buffer for data that does not change often or where the data does not need to be current.
What is correct to say about Native SQL: (There are three correct answers) Is only loosely integrated into ABAP and allows access to all of the functions contained in the programming interface of the respective database system You can primarily use the database-specific SQL statements You can use the full SQL language scope of the respective database and through the database-dependent layer makes all programs using Native SQL prepared for all database systems SAP recommends that ABAP applications contain more Native SQL as possible, because it brings more performance The database-dependent layer hides the differences between database systems from the rest of the database interface. When you use Native SQL, the function of the database-dependent layer is minimal.
Talking about Work processes types, select the correct explanation: Dialog work processes Update work processes Background work processes Enqueue work process Spool work process.
A dialog step is the program processing that occurs after a screen is released by a user or, put another way, the processing that occurs during a screen change (even if the same screen is being redisplayed). After the completion of a dialog step, the work process is released while the next screen is processed by the user on the presentation server. True False.
A repository object is one of the components (program, screen definitions, menus, function modules, and so on) stored in a special part of the database known as the Repository. True False.
The Internet Communication Manager (ICM)… Replaced SAP ITS Allows SAP NetWeaver Application Server to process HTTP requests Allows the ABAP stack and the Java stack to exchange data.
The Java stack and the ABAP stack of an SAP NetWeaver Application Server must always be installed together. True False.
A work process… Stays linked toa screen through the dispatcher Becomes inactive while waiting for a user Uses a common memory area called shared memory.
Each work process… (Select all that apply.) (There are three correct answers) Is independent of other work processes Uses a pool of database connections established when the SAP NetWeaver Application Server ABAP started Uses a database connection to a work process established when the SAP NetWeaver Application Server ABAP started Can only make database changes within a single database LUW Can make database changes spanning multiple database LUWs.
Each work process is assigned a type of task that can be performed. Which statements related to this are true? Select all that apply. (There are three correct answers) To switch a work process type requires a restart of the SAP NetWeaver Application Server ABAP All work processes have the same structure All work processes communicate with the database All work processes communicate with the dispatcher A work process can communicate directly with an external system through a Remote Function Call It is possible to have multiple enqueue work processes on an SAP NetWeaver Application Server It is possible to have multiple spool work processes on an ABAP application server.
What is the difference between SAP Basis and SAP NetWeaver? There is no difference; the name change was driven by marketing alone All versions of SAP NetWeaver require the use of Unicode All versions of SAP NetWeaver include the ability to handle HTTP requests.
The dispatcher handles all communication between users, work processes, and other (external) systems True False.
The ABAP messaging channels (AMC) uses the WebSocket protocol to gain two way communication instead of HTTP. True False.
