How do you modify the Java HotSpot Startup command to enable this feature and save the dump in the directory D:\hprof-dumps\?
- A. Add-xx:+HeapDumponoutofMemoryError-xx:Dumppath=D\hprof-dumps.
- B. Add -xx:+DumpHeaponoutofmemory-xx:Dumppath=D:\hprof.

You want to configure WebLogic Server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.
You also want to use the default store for transaction logs.
Which statement is true?
- A. This scenario is common, and so the default configuration of the default store works.
- B. Before the crash, you need to update the path to the default store for the managed server. The path should be to some shared storage location.
- C. This scenario is not possible. You must use clustered managed servers to recover transactions from a crashed server.
- D. After the crash, obtain a copy of the managed server's default store from the administration server. Move it to the same relative location on the new hardware before starting the managed server there.
- E. This scenario is not possible. You must use the JDBC store to recover transactions from a crashed server.
