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

    • Asynchronous RFC

    • Transactional RFC

    • Synchronous RFC

    • Queued RFC

    Correct Answer
    A. Queued RFC
    Explanation
    Queued RFC calls guarantee multiple communication steps in a specific order. In a Queued RFC, the system queues the RFC request and processes it in the order it was received. This ensures that the steps are executed sequentially, maintaining the desired order of communication. Asynchronous RFC does not guarantee a specific order as it allows parallel processing. Transactional RFC ensures atomicity and consistency but not a specific order. Synchronous RFC also does not guarantee a specific order as it waits for a response before proceeding.

    What happens when a buffered table is updated by an SQL request? There are 2 correct answers to this question.

    • The database is updated and the buffer of the current application server is invalidated.

    • Changes are written to table DDLOG, which is read at a certain interval to invalidate the buffered content on the other application servers.

    • The buffered table is updated at all application servers and the database is updated afterward asynchronously by report DDLOG.

    • Changes are written to table DDLOG, which is read at a certain interval to update the content of the database.

    Correct Answer(s)
    A. The database is updated and the buffer of the current application server is invalidated.
    A. Changes are written to table DDLOG, which is read at a certain interval to invalidate the buffered content on the other application servers.
    Explanation
    When a buffered table is updated by an SQL request, the first correct answer states that the database is updated and the buffer of the current application server is invalidated. This means that the changes made to the table are immediately reflected in the database, and the buffer in the current application server is cleared to ensure that the most up-to-date data is retrieved. The second correct answer explains that the changes are written to table DDLOG, which is periodically read to invalidate the buffered content on the other application servers. This ensures that all application servers have the latest data by periodically updating their buffers based on the changes recorded in table DDLOG.

    When you are investigating a database performance issue you find an often used expensive SQL statement that is doing a full table scan to access a small amount of data. No suitable index exists. How can you improve the performance of this query?

    • By creating an index using selective fields from the where clause.

    • By updating the statistics, so the optimizer will create an appropriate index.

    • By creating an index using all fields from the where clause.

    • By educating end users to use the program that calls this SQL statement correctly.

    Correct Answer
    A. By creating an index using selective fields from the where clause.
    Explanation
    To improve the performance of the query, creating an index using selective fields from the where clause is the best option. By doing this, the database can quickly locate the relevant data without having to perform a full table scan. This selective index will only include the necessary fields mentioned in the where clause, optimizing the query's performance by reducing the amount of data that needs to be scanned.

    • Not enough CPU resource available to hold the object in the buffer.

    • Not enough user activity to preserve the object in the buffer.

    • Not enough space left in the buffer for buffering the new object.

    • Not enough directory entries to buffer the new object.

    Correct Answer(s)
    A. Not enough space left in the buffer for buffering the new object.
    A. Not enough directory entries to buffer the new object.
    Explanation
    The two correct reasons for buffer swaps visible in the transaction Buffer Monitor (ST02) are not enough space left in the buffer for buffering the new object and not enough directory entries to buffer the new object. These reasons suggest that the buffer is running out of capacity to store new objects, either because there is not enough physical space available or because there are not enough directory entries to keep track of the objects in the buffer. This can lead to buffer swaps, where objects are removed from the buffer to make room for new ones.

    • In a Windows system, more than 20% of RAM paged out per hour.

    • In a Unix system, more than 20% of RAM paged in / swapped in per hour.

    • In a Windows system, more than 25% of RAM paged in per hour.

    Correct Answer(s)
    A. In a Unix system, more than 20% of RAM paged out/ swapped out per hour.
    A. In a Windows system, more than 25% of RAM paged in per hour.
    Explanation
    A memory bottleneck can be recognized in a Unix system when more than 20% of RAM is paged out or swapped out per hour. This indicates that the system is constantly moving data between RAM and disk, which can slow down the overall performance. In a Windows system, a memory bottleneck can be identified when more than 25% of RAM is paged in per hour. This suggests that the system is frequently loading data from disk into RAM, which can also impact the system's performance.

    Where and when is ABAP heap memory allocated?

    • In the local memory of the work process, when required

    • In the server memory of the work process, when required

    • In the system memory of the work process, when required

    • In the shared memory of the work process, when required

    Correct Answer
    A. In the local memory of the work process, when required
    Explanation
    ABAP heap memory is allocated in the local memory of the work process when required. This means that when a program or process in ABAP requires memory to store data, it will allocate that memory in the local memory of the work process. This memory is specific to that particular work process and is not shared with other processes or programs. The allocation happens dynamically as and when required, allowing for efficient memory usage.

    When you run transaction Table Call Statistics (ST10), which of the following indicates that a table should be unbuffered? There are 3 correct answers to this question

    • Tables with a high number of invalidations

    • Tables with a high number of "Rows affected"

    • Tables with a large buffer size

    • Tables with buffer state 'pending'

    • Tables with more direct reads than sequential reads

    Correct Answer(s)
    A. Tables with a high number of invalidations
    A. Tables with a high number of "Rows affected"
    A. Tables with a large buffer size
    Explanation
    When running transaction Table Call Statistics (ST10), a high number of invalidations, a high number of "Rows affected," and a large buffer size all indicate that a table should be unbuffered. Invalidations occur when data in the table is changed, which can cause performance issues if the table is buffered. "Rows affected" refers to the number of rows that are modified or accessed, which can also cause performance issues if the table is buffered. A large buffer size indicates that the table is consuming a significant amount of memory, which may be unnecessary if the table is not frequently accessed.

    With transaction Operating System Monitor (STO6) - Top 40 CPU Processes, you identified a process with unusually high CPU utilization. What are next steps to check the root cause? There are 2 correct answers to this question.

    • If it is a database process, you use the database monitor (ST04) and check if this activity can be tuned or moved to another time.

    • If this process leaves 10% or less overall CPU idle time, there is no need for further action because there is still headroom.

    • If it is an SAP work process, you compare the process ID (PID) to the list of transactions in SM50 to find out what activity is causing the load.

    • If it is the SAP gateway process, you might check if update processing can be moved to another instance.

    Correct Answer(s)
    A. If it is a database process, you use the database monitor (ST04) and check if this activity can be tuned or moved to another time.
    A. If it is an SAP work process, you compare the process ID (PID) to the list of transactions in SM50 to find out what activity is causing the load.
    Explanation
    To identify the root cause of the process with high CPU utilization, there are two next steps to consider. Firstly, if it is a database process, the database monitor (ST04) can be used to analyze if the activity can be optimized or scheduled for a different time. Secondly, if it is an SAP work process, comparing the process ID (PID) to the list of transactions in SM50 can help determine the specific activity causing the high load. These steps will help in identifying and addressing the root cause of the high CPU utilization.

    Which of the following is not a component of dialog response time? Choose the correct answer.

    • Wait time

    • Roll In/Out time

    • Database Request time

    • CPU idle time

    Correct Answer
    A. CPU idle time
    Explanation
    The question asks for a component that is not a part of dialog response time. Dialog response time refers to the time it takes for a system to respond to a user's input or request. The options given are wait time, roll in/out time, database request time, and CPU idle time. Wait time, roll in/out time, and database request time are all factors that can contribute to the overall response time. However, CPU idle time does not directly affect the dialog response time as it refers to the amount of time the CPU is not actively processing tasks.

    Which option represents "Generic area buffered"?

    • During the first access to a table, all table content is copied to the table buffer on the SAP instance.

    • You set some of key fields for a table to be used to determine the data to be buffered during access.

    • You set all key fields of a table to specify which records are buffered on the SAP instance.

    • Each individual record accessed is buffered on the SAP instance.

    Correct Answer
    A. You set some of key fields for a table to be used to determine the data to be buffered during access.
    Explanation
    This option represents "Generic area buffered" because it states that only some of the key fields for a table are set to determine the data to be buffered during access. This means that not all records are buffered, but only those that meet the specified criteria.

    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. A hardware bottleneck in the CPU occurs when the processing time is more than twice the CPU time. This means that the CPU is not able to handle the workload efficiently, resulting in slower processing times. A bottleneck can occur due to various reasons such as outdated hardware, insufficient processing power, or high demand on the system. When a hardware bottleneck occurs, it is necessary to upgrade the CPU or optimize the system to improve performance.

    • Distribute processes that do not need to run on this specific hardware to other hardware with unused capacity.

    • Increase CPU capacity to avoid that memory is being paged.

    • Optimize the database interface so that unneeded data is not being paged out.

    • Identify users/programs that cause high memory consumption and optimize expensive SQL statements and suboptimal programming.

    Correct Answer(s)
    A. Distribute processes that do not need to run on this specific hardware to other hardware with unused capacity.
    A. Identify users/programs that cause high memory consumption and optimize expensive SQL statements and suboptimal programming.
    Explanation
    To address the high paging rates, one possible countermeasure is to distribute processes that do not need to run on the specific hardware to other hardware with unused capacity. This helps to alleviate the memory usage on the overloaded hardware and prevent excessive paging. Another countermeasure is to identify users/programs that cause high memory consumption and optimize expensive SQL statements and suboptimal programming. By optimizing these aspects, the memory usage can be reduced, resulting in lower paging rates.

    when you run transaction table call statistics ST10, which of the following indicates that a table should be unbuffered? 3 right 

    • Tables with a high num of invalidations

    • Tables with a high num of 'rows affected'

    • Tables with a large buffer size

    • Tables with buffer state 'pending'

    • Tables with more direct reads than sequential reads

    Correct Answer(s)
    A. Tables with a high num of invalidations
    A. Tables with a high num of 'rows affected'
    A. Tables with a large buffer size
    Explanation
    Tables with a high number of invalidations, tables with a high number of 'rows affected', and tables with a large buffer size indicate that a table should be unbuffered. High invalidations suggest that the data in the table is frequently changing, making it inefficient to keep it in the buffer. Tables with a high number of 'rows affected' indicate that a large number of rows are being modified, which can also make buffering less efficient. Lastly, tables with a large buffer size may indicate that the table is too large to be effectively buffered, and unbuffering it can improve performance.

    • 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 is removed from the memory after a work process is finished or if it remains in memory for reuse.

    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? Choose 2 correct answers.

    • 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
    If the CPU utilization is consistently near 100%, it indicates that the system is using the maximum processing power available and there may be a hardware bottleneck causing the system to slow down. Similarly, high swap/paging activity suggests that the system is frequently accessing the disk to swap data between memory and disk, which can indicate a lack of available memory or a slow disk subsystem. Both of these scenarios can indicate hardware bottlenecks in the SAP system.

    Why are parts of user contexts stored in SM50 (extended?) memory instead of local memory of a system?

    • To speed up context switches (roll-in/ roll-out)

    • To speed up context switches (dialog time/ roll-out)

    • To speed up context switches (roll-in/ enqueue time)

    • To speed up context switches (roll-in/ processing time)

    Correct Answer
    A. To speed up context switches (roll-in/ roll-out)
    Explanation
    Parts of user contexts are stored in SM50 (extended) memory instead of local memory of a system to speed up context switches during roll-in and roll-out processes. Storing user contexts in SM50 memory allows for faster retrieval and loading of the necessary data when a context switch occurs, improving the overall efficiency and performance of the system.

    What are some of the reasons for using the extended memory concept in SAP systems? There are 3 correct answers to this question.

    • Without extended memory, a release of allocated memory in the OS paging file would not be possible.

    • The large size of extended memory avoids context switches where possible.

    • Fast context switches are needed in SAP systems because many users share few work processes.

    • Extended memory is accessed through pointers, therefore fast context switches are possible.

    • SAP transactions usually consist of more than one step or screen.

    Correct Answer(s)
    A. Fast context switches are needed in SAP systems because many users share few work processes.
    A. Extended memory is accessed through pointers, therefore fast context switches are possible.
    A. SAP transactions usually consist of more than one step or screen.
    Explanation
    The extended memory concept is used in SAP systems for several reasons. Firstly, fast context switches are needed because many users share a limited number of work processes. This allows for efficient multitasking and ensures that users can quickly switch between different tasks. Secondly, extended memory is accessed through pointers, which enables fast context switches to occur. This means that data can be accessed and processed quickly, improving system performance. Lastly, SAP transactions often involve multiple steps or screens, so having extended memory allows for the storage of large amounts of data and ensures smooth execution of these transactions.
