     SWAPS in transaction ST02 are an indication of high CPU utilization. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. SWAPS in transaction ST02 are not an indication of high CPU utilization. SWAPS refer to the process of moving data between the main memory and the disk when the available memory is not sufficient. It is a measure of memory usage and not directly related to CPU utilization. High SWAPS may indicate a lack of memory, but it does not necessarily imply high CPU utilization.

     Which of the following profile parameters affect activation of dynamic work processes? Choose the correct answer.

    •  rdisp/wp_no_dia

    •  rdisp/wp_no_btc 

    •  rdisp/wp_no_enq 

    •  rdisp/dynamic_wp_check

    Correct Answer
    A.  rdisp/dynamic_wp_check
    Explanation
    The profile parameter "rdisp/dynamic_wp_check" affects the activation of dynamic work processes. This parameter determines whether the system should check for the availability of dynamic work processes before executing a transaction. If this parameter is set to "1", the system will check for available work processes dynamically. If it is set to "0", the system will not perform this check. This parameter helps in managing the workload efficiently by activating additional work processes only when needed.

  • 5. 

     Virtual memory is made up of OS swap or page file and physical memory components. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true. Virtual memory is indeed made up of OS swap or page file and physical memory components. The OS swap or page file is a portion of the hard drive that is used as an extension of the computer's physical memory. When the physical memory becomes full, the operating system moves some data from the RAM to the swap file to free up space for other processes. This allows the computer to efficiently manage memory and run multiple programs simultaneously.

    Rate this question:

  • 6. 

    In transaction ST02, there is a problem if there is a lot of swapping in the SAP buffers. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In transaction ST02, there is a problem if there is a lot of swapping in the SAP buffers. This statement is true. Swapping refers to the process of moving data between the main memory and the disk when there is limited memory available. If there is excessive swapping in the SAP buffers, it can lead to performance issues and slow down the system. Therefore, it is considered a problem if there is a lot of swapping in the SAP buffers.

    Rate this question:

  • 7. 

     Which of the following parameters lead to the allocation of heap memory for dialog processes? Choose the correct answers.

    •  em/initial_size_MB 

    • Em/max_size_MB 

    •  rdisp/roll_SHM 

    •  Ztta/roll_extension

    Correct Answer(s)
    A. Em/max_size_MB 
    A.  Ztta/roll_extension
    Explanation
    The parameters "em/max_size_MB" and "Ztta/roll_extension" lead to the allocation of heap memory for dialog processes. The "em/max_size_MB" parameter determines the maximum size of the extended memory (heap memory) that can be allocated for a dialog process, while the "Ztta/roll_extension" parameter determines the size of the extended memory (heap memory) used for roll area extensions in a dialog process.

    Rate this question:

  • 8. 

     The user’s context is initially stored in the heap area in the shared memory.. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false. The user's context is not initially stored in the heap area in the shared memory. The user's context typically includes information such as the program counter, registers, and stack pointer, and it is usually stored in the stack area of the memory. The heap area is used for dynamically allocated memory, while the shared memory is a region of memory that can be accessed by multiple processes or threads.

    Rate this question:

  • 9. 

    Which of the following from the Operating System Monitor (transaction ST06) indicates that there is some hardware bottleneck in the SAP system if it happens all the time? 

    •  High CPU utilization near 100%

    •  High CPU idle time

    •  High swap/paging activity

    •  High DB time

    Correct Answer(s)
    A.  High CPU utilization near 100%
    A.  High swap/paging activity
    Explanation
    High CPU utilization near 100% indicates that the CPU is constantly busy and unable to handle the workload efficiently. This can be a sign of a hardware bottleneck as the CPU is unable to keep up with the demands of the system. High swap/paging activity also suggests a hardware bottleneck as it indicates that the system is frequently using disk space as virtual memory, which can slow down performance. Both of these factors point to a potential hardware limitation in the SAP system.

    Rate this question:

  • 10. 

    There is hardware bottleneck in the CPU if processing time is more than twice the CPU time. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because a hardware bottleneck occurs when the processing time is significantly longer than the CPU time. If the processing time is more than twice the CPU time, it indicates that the CPU is not able to handle the workload efficiently, resulting in a bottleneck. This can lead to slower overall performance and reduced efficiency in processing tasks.

    •  SQL statement which requires many records to be transferred to the ABAP program.

    •  SQL statement which uses index during data retrieval

    •  SQL statement which reads many blocks but retrieves only a few records from the database.

    •  SQL statement which uses table buffering.

    Correct Answer(s)
    A.  SQL statement which requires many records to be transferred to the ABAP program.
    A.  SQL statement which reads many blocks but retrieves only a few records from the database.
    Explanation
    An expensive SQL statement is one that requires a large number of records to be transferred to the ABAP program or reads many blocks but retrieves only a few records from the database. These operations can be time-consuming and resource-intensive, leading to slower performance and increased costs. SQL statements that use indexes during data retrieval or table buffering can actually improve performance by optimizing data access and reducing the need for full table scans.

    Programs which show database request time > 40 % (response time – wait time) in the transaction profile of ST03 are potential candidates for containing expensive SQL statements. Determine whether this statement is true or false.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true. In the transaction profile of ST03, if the database request time is greater than 40% of the response time minus the wait time, it indicates that the SQL statements used in the program are taking a significant amount of time to execute. This suggests that the program may contain expensive SQL statements, which could be optimized to improve performance.

    Which of the following are valid options for table buffering types? Choose the correct answers.

    •  Single record buffered

    • Generic area buffered

    •  Fully buffered

    •  Client specific buffered

    Correct Answer(s)
    A.  Single record buffered
    A. Generic area buffered
    A.  Fully buffered
    Explanation
    The valid options for table buffering types are "Single record buffered," "Generic area buffered," and "Fully buffered." These buffering types are used in different scenarios to optimize data access and improve performance in SAP systems. "Single record buffered" buffers only one record at a time, "Generic area buffered" buffers a range of records, and "Fully buffered" buffers the entire table. These buffering types allow for faster data retrieval and reduce the need for frequent database access, improving overall system performance.

    Rate this question:

     Which of the following parameter controls the buffer synchronization behavior in the SAP system? Choose the correct answer.

    • Rdisp/ddlogmode

    • Rdisp/switch_bufmode

    •  rdisp/bufremode

    •  rdisp/auto_buf

    Correct Answer
    A.  rdisp/bufremode
    Explanation
    The parameter "rdisp/bufremode" controls the buffer synchronization behavior in the SAP system. This parameter determines whether the buffer should be removed or not when a process is terminated. By setting this parameter to a specific value, the system can be configured to either remove the buffer or keep it intact when a process is terminated.

    Rate this question:

  • 21. 

     Table buffering is recommended for which of the following scenarios ? Choose the correct answers.

    • Tables that are seldom changed.

    •  Large tables that are often accessed.

    •  Customizing data.

    •  Transaction data.

    Correct Answer(s)
    A. Tables that are seldom changed.
    A.  Customizing data.
    Explanation
    Table buffering is recommended for tables that are seldom changed and for customizing data. Table buffering involves storing frequently accessed data in the application server's memory, which improves performance by reducing the number of database accesses. This is particularly useful for tables that are seldom changed, as it allows for faster retrieval of data without the need to constantly access the database. Additionally, customizing data, which refers to data that is specific to a particular system or organization, can also benefit from table buffering as it often remains unchanged and is frequently accessed.

    • True

    • False

    • I am a shadow

    • A shadow in the dark

    Correct Answer
    A. False
    Explanation
    The statement is false because SQL trace (transaction ST05) provides information on SQL statement execution and performance, not on table accesses, database activities, ABAP requests, or invalidations.

    Rate this question:

    Which of the following types of RFC calls guarantees multiple communications steps in a specific order? 

    •  Asynchronous RFC

    •  Transactional RFC

    • Queued RFC

    • Synchronous RFC

    Correct Answer
    A. Queued RFC
    Explanation
    Queued RFC calls guarantee multiple communication steps in a specific order. In a Queued RFC, the system stores the request in a queue and processes it in the order it was received. This ensures that the communication steps are executed sequentially and in the desired order. Unlike other types of RFC calls, Queued RFCs allow for reliable and ordered message processing, making them suitable for scenarios where strict sequencing is required.

    Rate this question:

  • 24. 

     What is RFC+CPIC time in synchronous RFC? Choose the correct answer.

    •  Time needed to establish the RFC communication to the RFC server.

    •  Time needed to establish the RFC communication plus roll out time, roll wait time, and roll in time.

    • Roll wait time caused by RFC communication

    •  GUI time.

    Correct Answer
    A.  Time needed to establish the RFC communication plus roll out time, roll wait time, and roll in time.
    Explanation
    The RFC+CPIC time in synchronous RFC refers to the time needed to establish the RFC communication to the RFC server, as well as the roll out time, roll wait time, and roll in time. This means that it includes the time required for establishing the communication channel and also the time for data transfer and processing. Additionally, it takes into account any delays caused by the roll out, roll wait, and roll in processes. The GUI time, on the other hand, is not relevant to the RFC+CPIC time in synchronous RFC.
