Exam SY0-601 topic 1 question 87 discussion

Definitely memory leak ' key sentence' -> The administrator increases the virtual memory allocation, which improves conditions, but performance degrades again after a few days. Memory leak occurs when programmers create a memory in heap and forget to delete it. The consequences of memory leak is that it reduces the performance of the computer by reducing the amount of available memory. Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly .

Memory leak

A memory leak is a bug in a computer application that causes the application to consume more and more memory the longer it runs. In extreme cases, the application can consume so much memory that the operating system crashes. Memory leaks are typically caused by an application that reserves memory for short-term use but never releases it. For example, imagine a web application that collects user profile data to personalize users’ browsing experiences. However, it collects this data every time a user accesses a webpage, and it never releases the memory used to store the data. An initial indicator of a memory leak is a system running slower and slower until it is rebooted. It’s possible to detect memory leaks by looking at the memory usage per application in operating system tools, such as the Windows Task Manager.

D. Memory leak

I love these questions, answer is right in the question :) I bet we get at least 15 of those on the test, yeah? A+, AZ-900, SC-900, all of em seem to follow the same scheming.

The output from the analysis tool indicates that there is a memory issue, specifically a memory leak. A memory leak occurs when a program fails to release memory that is no longer needed, leading to the gradual consumption of memory over time. In this case, the timeAttend.exe process is causing the memory leak, and terminating the process has resolved the performance degradation issue.

A memory leak occurs when a program or process does not release memory resources properly after it is no longer needed. As a result, memory consumption continues to increase over time, leading to degraded performance and potential system instability. In this case, the system administrator observed degraded performance on the virtual server, which improved temporarily after increasing the virtual memory allocation. However, the performance degraded again after a few days. The output of the analysis tool indicates that there are 4608 bytes in 18 blocks of memory that are "definitely lost" at the time of exit. By terminating the "timeAttend.exe" process and observing that the system performance does not degrade afterward, it suggests that the memory leak issue was related to the "timeAttend.exe" process. Terminating the process would release the allocated memory, resolving the memory leak and improving system performance.

The issue that is most likely occurring is a memory leak. A memory leak occurs when a program allocates memory dynamically, but does not free it properly. Over time, this results in a gradual increase in memory usage, leading to degraded system performance and eventually to a crash. The output from the analysis tool shows that timeAttend.exe is the cause of the memory leak, as it has 4608 bytes in 18 blocks of memory that are definitely lost. Terminating the timeAttend.exe process and observing improved system performance confirms this diagnosis.

WHO IS STONEFACE?

memory leak

I think B. API attack

Memory leaks are usually caused by failure to deallocate memory that has been allocated.

Thank you Stoneface!

Well spotted stoneface. Agree with you on D for this one.
