Question 5

After deploying a new application to a high load production system, a memory leak has been detected which causes OutOfMemory exceptions. After fixing this, a system administrator needs to gather JVM heap dumps and restart the server in case a memory leak is detected in the future. How should the system administrator handle this without writing a script? Create a health policy which will:

A. use the Job Manager to put server in maintenance mode, gather JVM heap dump and restart the server.

B. take the server out of maintenance mode, gather JVM heap dump and restart the server.

C. put the server in maintenance mode, gather JVM heap dump and restart the server.

D. send the SNMP trap to generate the heap dump and restart the server.

Correct Answer: C
