Sample Questions

  1. Which of the following are the benefits of SAP Router?

Note: There are three correct answers to the question

a. Increases network security
b. Determines the language version of the online help displays
c. Offers its customers access to support
d. Required for remote support connections
e. Simplifies Network configuration

Answer: a, d, e

 Explanation:

  • SAP router increases network security simplifies network configuration and allows you to make indirect network connections. SAP router is required for remote support connections.
  • SAP router Functions Controls and logs connections to your SAP system, for example, from an SAP service center
  • Sets up indirect connection when programs involved in the connection cannot communicate with each other due to the network configuration
  • Improves network security by means of:
    • A password, which helps to protect your connection and data from unauthorized external access
    • Access from particular SAP routers only
    • Access of only encrypted connect ions from a known partner by using the Secure Network Communication (SNC) layer
  • Increases performance and stability by reducing the SAP system workload in a LAN when communicating with a WAN
  1. Which of the following steps are needed to install additional languages?

Note: There are three correct answers to the question

a. Classifying the language
b. Scheduling of language transport or import
c. Scheduling of language supplementation
d. Supplementing of periodic language for newly generated texts
e. Regenerating the language texts for translation

Answer: a, b, c

Explanation:

We need to classify the language, schedule language transport or import and schedule language supplementation to install additional languages.

Depending on the release status the SAP system supports up to 40 different languages. The language with which a user works is specified through entry on the logon screen by a system default or by a default set ting in the user master record.

This language must first be imported into the SAP system before users can log on with the desired language. Only German (DE) and English (EN) are initially installed after a new installation of an SAP system. lf required you can use transaction SMLT to import additional languages.

If you select a language (other than DE, EN, or Japanese) you should note that the selected language is not fully translated. The texts that are not translated in the selected language must be provided using a supplemental language. This supplement al language must be a completely translated language. This can also be recursively configured so that you use a number of supplemental languages.

  1. Which protocol is used to implement the cross system standard scenarios?

a. Transmission control Protocol
b. Remote Function Call
c. Internet Protocol
d. SAP Mail Transfer Protocol

Answer: b

Explanation:

When using standard cross-system SAP processes such as an SAP ERP Central Component system connected to an external system that is for example not RFC-enabled it is useful to install a standalone SAP Gateway instance.

These cross-system standard scenarios are implemented through Remote Function Call (RFC).For example, for Human Resource (HR) reasons, (such as time registration), you use third-party software to read the access cards of the employees entering or leaving the company. This information needs to be transferred to your SAP ERP Central Component (HR) system to be processed.

It the time registration software is not RFC enabled, you can install a standalone SAP Gateway instance on the host of the third-party software. The time registration software can communicate with the SAP Gateway instance, for example, through Transmission Control Protocol (TCP) or Internet Protocol (IP).

Within your SAP ERP Central Component system you can use the standard RFC-based scenarios to communicate through the standalone SAP Gateway with the time registration software.

  1. Which of the following are the advantages of SAPinst compared to R3setup?

Note: There are two correct answers to the question

a. Set back to correct your entries during the input phase without restarting the installation
b. It does not abort because of errors occurred during the installation
c. It records installation progress in a multiple log file
d. You cannot start SAPinst GUI on a remote server

Answer: a, c

Explanation:

The System Landscape Implementation Manager (SAPinst) offers these main advantages compared to R3SETUP:

  • SAPinst lets you step back to correct your entries during the input phase without restarting the installation.
  • SAPinst does not abort because of errors. Instead, it stops the installation and you can retry the installation after solving the problem. Alternatively, you can abort the installation manually if you want.
  • SAPinst continues an aborted installation directly from the point of failure.
  • SAPinst records installation progress in a single log file, log.
  • You can start SAPinst GUI on a remote computer if you want.
  • SAPinst has a graphical user interface (GUI), SAPinst GUI, which allows you to monitor the progress of the installation and see all messages issued by SAPinst
  1. An SAP System must be installed on which file system of Windows?

a. FAT
b. HPFS
c. NTFS
d. None of the above

Answer:  c

 Explanation:

An SAP system must be installed on an NTFS file system.

NTFS (New Technology File System) is the standard file system of Windows NT, including its later versions Windows 2000Windows XPWindows Server 2003Windows Server 2008,Windows Vista, and Windows 7.

Do not install the SAP directories on a FAT partition. Check the partition on which you plan to install the SAP system for the correct file system.

Follow this procedure to check the file system of the installation partition:

  • Open Windows Explorer.
  • Select the root directory.
  • Choose Properties.
  • Switch to the General tab to see the type of file system that is in use
  1. Which of the following preparations are required before installing or run the SAPinst in the context of Windows?

a. Java Software Development Kit to be installed
b. Clean up the JDK\ext directory
c. Set the JAVA_HOME environment variable
d. All of the above

Answer: d

 Explanation:

SAPinst is a Java-based tool, the Java Software Development Kit (abbreviated as SDK or JDK) must be installed on all hosts where SAPinst will run. After installing the Java SDK, some rework is mandatory.

Check the Java \ext directory to see if there is already <parser_name>.jar files. If exist, rename them for the current installation. Remember to rename the files back to their original names after the installation procedure is complete. SAPinst needs the JAVA_HOME environment variable to be set on the host(s) where SAPinst will run.  Check if the system variable JAVA_HOME is set to the Java home directory; if it is not set create a new variable.

You have to add the Java home directory to the Path variable. Enter %JAVA_HOME%\bin at the end of the Variable Value field. Use a semicolon (;) to separate the entry from the previous entry!

  1. Which of the following value to be set for the DISPLAY environment variable to run the SAPinst in the context of UNIX?

a. <host_name>0.0
b. <host_name>1.0
c. <host_name>2.0
d. None of the above

Answer:  a

 Explanation:

Make sure that DISPLAY is set to <hostname>:0.0, where<hostname> is the host on which SAPinst GUI is to be displayed. Typically, this is the hostname or IP address of your local host.

  1. Which of the following statement is true for Unicode SAP system installation in the context of UNIX?

a. The setting of the library path environment variable is required only for the central system and the database instance installation
b. The setting of the library path environment variable is does not required
c. The setting of the library path environment variable is required only specific instances
d. The setting of the library path environment variable is required for all SAP instance installations

Answer:  d

 Explanation:

Non-Unicode SAP system installation:

– The setting of the library path environment variable is required only for the central system and the database instance installation.

Unicode SAP system installation:

– The setting of the library path environment variable is required for all SAP instance installations.

  1. SAPinst first checks the availability and location of the required installation CDs or Software packages during the installation process. Which file contains the information about these software packages or installation CDs?

a. dialog.xml
b. Message.asc
c. Label.asc
d. None of the above

Answer:  c

 Explanation:

 SAPinst first checks the and finally verify the availability and location of the required installation CDs or Software packages. The information of these CDs or Packages is stored in a file called LABEL.ASC.

During the Installation process, System displays a CD browser which takes the location of the file LABEL.ASC in the “PACKAGE LOCATION” column and also ticks the check box “CHECK LOCATION”.

  1. If you want to install one SAP system from another SAP system having the same database system and operating system, which installation method can be used to copy the SAP system?

a. Homogeneous System copy
b. Heterogeneous System copy
c. Migration System copy
d. All of the above

Answer: a

Explanation:

    • You perform a homogeneous system copy if your target system is on the same operating system and database system as your source system. The database contents are copied from the source system to the target system.
    • You perform a heterogeneous system copy if you want to change the operating system or database system. Migration is another term for a heterogeneous system copy.

When you perform a system copy, all software units or usage types in the source system are copied to the target system. This means that none of the usage types in the target system can be excluded from the system copy, nor can you select usage types.

  1. Which of the following user is required to enable communication between ABAP and JAVA stack?

a. SAPUSER
b. SAPJSF
c. SAPJER
d. None of the above

Answer: b

Explanation:

The user SAPJSF is required to enable communication between ABAP and Java stack. User SAPJSF will be created using the function module.

The communication user SAPJSF is used during the user authentication that takes place between the JEEE Security service and the SAP Web Application Server by RFC communication.

During the installation of the SAP Web Application Server and/or the activation of the J2EE Engine, the communication user is automatically created and received the role SAP_BC_JSF_COMMUNICATION_RO.

This means that the user has only read access to all user data and can. The role contains the authorization with which the communications user can authenticate the end user. During the installation or activation of the SAP J2EE Engine, the system prompts you to specify a password for the communication user. The communication user is then automatically created.

  1. If the dialog instance is installed on the same host as the central instance, which of the following statement is correct?

a. Both instances must be assigned to same number
b. Both instances must be assigned to different numbers
c. No number assignment is required
d. All of the above

Answer: b

Explanation:

If more than one instance running on the same host, both instances must be assigned different numbers. So, if you are installing dialog instance on the same host as the central instance, you must assign different numbers. You can specify a value from 00 to 97.

  1. Which of the following is the default message server port number in the central instance installation?

a. 30<Instance Number>
b. 35<Instance Number>
c. 36<Instance Number>
d. 33<Instance Number>

Answer: c

Explanation:

The default message server port number in the central instance installation is 36<Instance Number>. Instance number is the same number given for the central instance.

Instance Number is the two digit number given at the time of installation.

The port number of the message server port must be the same as the one on the central instance host

  1. Which of the following work process types are there in the SAP System?

 Note: There are three correct answers to the question

a. Update Work process
b. Spool Work Process
c. Instance Work Process
d. Dialog work process
e. Gateway work Process

Answer: a, b, d

Explanation:

The ICM (Internet Communication Manager) is not a work process but a service of the SAP Net Weaver Application Server; similarly, the gateway. The instance itself is not a work process. In addition to the correct work process types listed above, there are also background work processes and Enqueue work processes.

      • Dialog work processes (D) deal with requests from an active user to execute dialog steps. Each dispatcher needs at least two dialog work processes.
      • The Update work processes (U or V) execute database update requests. Update requests are part of an SAP LUW that bundle the database operations resulting from the dialog in a database LUW for processing in the background. It is possible to configure more than one per dispatcher.
      • The Enqueue work process (E) administers a lock table in the shared memory area. The lock table contains the logical database locks for Net Weaver AS ABAP and is an important part of the SAP LUW concept. In NW AS, you may only have one lock table. You may therefore also only have one ABAP application server with Enqueue work processes. Normally, a single Enqueue work process is sufficient to perform the required tasks.
      • Background work processes process (B) programs that can be executed without user interaction (background jobs). Each SAP system needs at least two background work processes. You can configure more than one background work process per dispatcher.
      • The spool work process (S) passes sequential datasets to a printer or to optical archiving. Each ABAP SAP System contains at least one spool work process. It is possible to configure more than one spool work process per dispatcher
  1. Which of the following technology ABAP based SAP systems use to process user requests?

a. Work process Multiplexing
b. Dispatcher handling
c. VM container technology
d. Communication Manager

Answer: a

Explanation:

Dialog Work Process Multiplexing: The processing of a transaction that consists of multiple screens is usually executed using multiple, different dialog work processes. This distribution is called work process multiplexing. Work process multiplexing means that a system function whose content is logically connected but consists of multiple sub steps can be processed by various dialog work processes.

These steps, where the content is connected, are described as transactions. A transaction that consists of multiple screens, such as screens 100 and 200 can also be processed by multiple dialog work processes.

The figure shows two screens of a transaction (100 and 200), for which the input is handled by two different dialog work processes. The multiplexing procedure is used exclusively for dialog work processes. All other work process types process entire functions; that is, complete business processes.

As dialog work processes may therefore process only parts of transactions that are connected from a business point of view; the update procedure with the update work process is widely used in SAP systems.
