Which of the following is not a component of dialog response time?
- A.
Wait time
- B.
Roll In/Out
- C.
Database Request
- D.
CPU idle time
Correct Answer
D. CPU idle timeExplanation
CPU idle time is not a component of dialog response time. Dialog response time refers to the time it takes for a system or application to respond to a user's input or request. It includes factors such as wait time (time spent waiting for a response), roll in/out (time to load or unload data), and database request (time to retrieve or update data from a database). CPU idle time, on the other hand, refers to the time when the CPU is not actively processing any tasks. It is not directly related to the response time of a dialog.Rate this question:

Virtual memory is made up of OS swap or page file and physical memory components.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Virtual memory is a memory management technique used by operating systems to provide the illusion of having more physical memory than is actually available. It is made up of two main components: the OS swap or page file, which is a portion of the hard drive used as an extension of physical memory, and the physical memory itself, which includes RAM. This allows the operating system to store data that is not currently being used in physical memory and retrieve it when needed. Therefore, the statement that virtual memory is made up of OS swap or page file and physical memory components is true.Rate this question:

The executing work process has a long-running action with "semaphore".
Correct Answer(s)
A. The executing work process has a long-running action with "sequential read".
C. The executing work process has a long-running action with "direct read".Explanation
The presence of a long-running action with "sequential read" and "direct read" in the executing work process indicates potentially expensive SQL statements in programs with transaction Local Work Process Overview (SM50). These actions suggest that the work process is spending a significant amount of time reading data sequentially or directly from the database, which can be a sign of inefficient or poorly optimized SQL queries. By identifying these actions, one can focus on optimizing the corresponding SQL statements to improve performance and potentially reduce costs.Rate this question:

You are investigating a performance problem. In transaction Work Process Overview (SM50 or SM66) you see that many work processes stay in status 'running' with action 'read directly' and 'sequential read' for a long time. What do you do next?
- A.
Analyze the database.
- B.
Analyze the SAP memory configuration.
- C.
Perform a LAN Check by Ping.
- D.
Check the 'Top 40 CPU Processes' in transaction Operating System Monitor (ST06(n))
Correct Answer
A. Analyze the database.Explanation
The correct answer is to analyze the database. This is because the given information suggests that the work processes are spending a long time in the 'running' status with actions related to reading data from the database. Therefore, it is logical to investigate the performance of the database to identify any issues or bottlenecks that may be causing the delay in processing. Analyzing the SAP memory configuration, performing a LAN check, or checking the top CPU processes may be relevant in other scenarios, but in this specific case, analyzing the database is the most appropriate next step.Rate this question:

Where can you find the top expensive SQL statements on the system?
- A.
In the cursor cache of the DBS Cockpit.
- B.
In the transaction Operating System Monitor (ST06(n)).
- C.
In transaction SQL trace (ST05 or ST12).
- D.
In transaction Work Process Overview (SM50 and SM66).
Correct Answer
A. In the cursor cache of the DBS Cockpit.Explanation
The cursor cache of the DBS Cockpit is the correct answer because it is the specific location where the top expensive SQL statements on the system can be found. The other options mentioned (transaction Operating System Monitor, transaction SQL trace, and transaction Work Process Overview) do not specifically mention the cursor cache of the DBS Cockpit as the location to find the top expensive SQL statements.Rate this question:

In which sequence do dialog work processes allocate memory as of SAP NetWeaver 7.40?
- A.
Extended memory, Heap memory
- B.
Heap memory, Extended memory
- C.
Local memory, Extended memory, Heap memory
- D.
Heap memory, Extended memory, PRIV memory
Correct Answer
A. Extended memory, Heap memoryExplanation
In SAP NetWeaver 7.40, dialog work processes allocate memory in the sequence of extended memory first and then heap memory. Extended memory is used for storing large amounts of data that cannot fit in the main memory, while heap memory is used for dynamic memory allocation during program execution. This sequence ensures that the dialog work processes first utilize the extended memory for data storage and then use the heap memory for any additional memory requirements.Rate this question:

Which of the following areas of an instance's shared memory has a corresponding file on hard disk to which SAP system will copy data that would not fit in that shared memory area?
- A.
PROC buffer.
- B.
Paging buffer.
- C.
SAP buffer (programs, tables, and so on).
- D.
Extended memory (user contexts).
Correct Answer
B. Paging buffer.Explanation
The paging buffer in an instance's shared memory is used to store data that cannot fit in the shared memory area. This data is copied to a corresponding file on the hard disk by the SAP system. This allows the system to free up space in the shared memory area and retrieve the data from the hard disk when needed. The other options, such as PROC buffer, SAP buffer, and extended memory, do not involve copying data to the hard disk.Rate this question:

What are some of the negative effects of incorrect table buffering settings? There are 2 correct answers
- A.
If a buffered table is seldom changed, there is a risk of reading outdated data.
- B.
If a buffered table is accessed too often, there is a risk that the statistics of the database optimizer will become outdated.
- C.
If a buffered table is very large, there is a risk that other buffered tables will be swapped out because of missing free space.
- D.
If the content of a buffered table is changed very often, the process to refill the table buffer can reduce the overall system performance.
Correct Answer(s)
C. If a buffered table is very large, there is a risk that other buffered tables will be swapped out because of missing free space.
D. If the content of a buffered table is changed very often, the process to refill the table buffer can reduce the overall system performance.Explanation
If a buffered table is very large, there is a risk that other buffered tables will be swapped out because of missing free space. This means that if the table is taking up a lot of memory space, it may cause other tables to be removed from the buffer in order to make space for it. This can result in slower performance and increased response times for accessing those other tables.
If the content of a buffered table is changed very often, the process to refill the table buffer can reduce the overall system performance. This means that if the data in the table is frequently updated or modified, the buffer needs to be constantly refilled with the updated data. This process can be resource-intensive and can slow down the overall system performance.Rate this question:

In the transaction profile of transaction Workload Monitor (ST03n), how do you identify a poorly performing program that may be causing overall performance problems? There are 2 correct answers
- A.
Its total response time and average response time are high.
- B.
Its average CPU time and/or database time are high.
- C.
Its number of steps is very low.
- D.
Its average CPU time is greater than the average processing time.
Correct Answer(s)
A. Its total response time and average response time are high.
B. Its average CPU time and/or database time are high.Explanation
The correct answers suggest that a poorly performing program can be identified by looking at its total response time and average response time, as well as its average CPU time and/or database time. If these metrics are high, it indicates that the program is taking longer to respond and is consuming a significant amount of CPU or database resources, which may be causing overall performance problems. The number of steps or the comparison between average CPU time and average processing time are not reliable indicators of a poorly performing program.Rate this question:

In transaction Workload Analysis Monitor (ST03n), average roll-wait time for task type DIALOG is high. Which of the following can cause this issue? There are 2 correct answers
- A.
Not enough dialog work processes configured.
- B.
Problems with the external RFC communication.
- C.
SAP roll Area is too small.
- D.
Communication problems with the GUI front end.
Correct Answer(s)
B. Problems with the external RFC communication.
D. Communication problems with the GUI front end.Explanation
Problems with the external RFC communication can cause a high average roll-wait time for task type DIALOG in transaction Workload Analysis Monitor (ST03n). This is because if there are issues with the external RFC communication, it can lead to delays in data retrieval or processing, causing the dialog tasks to wait for longer periods of time. Similarly, communication problems with the GUI front end can also contribute to a high roll-wait time as it can result in delays or interruptions in the user interface interactions, leading to longer wait times for the dialog tasks.Rate this question:

What are some possible effects if the program buffer was made too small in configuration? There are 3 correct answers
- A.
An increased number of work processes accessing table REPOLOAD
- B.
Increased load and generation time in transaction ST03.
- C.
An increased number of program buffer swaps visible in transaction ST02.
- D.
An increased number of work processes entering PRIV mode.
- E.
Increased GUI time caused by unbuffered objects.
Correct Answer(s)
A. An increased number of work processes accessing table REPOLOAD
B. Increased load and generation time in transaction ST03.
C. An increased number of program buffer swaps visible in transaction ST02.Explanation
If the program buffer was made too small in configuration, it would lead to an increased number of work processes accessing table REPOLOAD. This is because the program buffer stores frequently accessed programs, and if it is too small, more work processes would need to access the table directly. Additionally, it would result in an increased load and generation time in transaction ST03, as the system would need to generate programs more frequently. Lastly, there would be an increased number of program buffer swaps visible in transaction ST02, indicating that the buffer is constantly being filled and emptied, causing performance issues.Rate this question:

How can SAP shared memory be accessed?
- A.
Shared memory is only accessible on operating system level.
- B.
Shared memory is accessible by all processes across all instances.
- C.
Shared memory is accessible only by dialog work processes of one instance.
- D.
Shared memory is accessible by all processes of one instance.
Correct Answer
D. Shared memory is accessible by all processes of one instance.Explanation
Shared memory is a form of memory that can be accessed by multiple processes within a single instance of SAP. This means that any process running within that instance can read from and write to the shared memory. It allows for efficient data sharing and communication between different processes, improving overall system performance. However, shared memory is not accessible across different instances or on the operating system level, limiting its scope to processes within a single SAP instance.Rate this question:
