Output 1:

Output 2:

Output 3:

Which of the following should the administrator do to provide the BEST solution for the reported issue?

A. Configure memory allocation policies during business hours and prevent the Java process from going into a zombie state while the server is idle.
B. Configure a different nice value for the Java process to allow for more users and prevent the Java process from restarting during business hours.
C. Configure more CPU cores to allow for the server to allocate more processing and prevent the Java process from consuming all of the available resources.
D. Configure the swap space to allow for spikes in usage during peak hours and prevent the Java process from stopping due to a lack of memory.

I choose answer D. The system killed the java process because of lack of memory, but no one has configured a swap partition! That will help. A swap partition is generally recommended as one of the two main partitions created during a linux installation.

C. Configure more CPU cores to allow for the server to allocate more processing and prevent the Java process from consuming all of the available resources. Adding more CPU cores can help distribute the load and handle higher CPU demands, potentially resolving the issue of high CPU usage by the Java process.

Given this, the best solution would be to configure the swap space to allow for spikes in usage during peak hours and prevent the Java process from stopping due to a lack of memory. This can be done by increasing the size of the swap space or adding more swap space. This will provide a buffer for the system when it runs out of physical memory, preventing the OOM killer from being invoked and the Java process from being killed. So, the correct answer is D. Configure the swap space to allow for spikes in usage during peak hours and prevent the Java process from stopping due to a lack of memory.
