You are troubleshooting an application and suspect that the issue lies with the use of Java Virtual Machine threads. Because of firewall restrictions, you cannot use web-based consoles to access the WebLogic Server diagnostic information.
Which command-line operations could you use to investigate the internal state of JVM threads?

• A.* Log in to the Managed Server VM via SSH* Use the Linux command: kill -SIGDUMP
  < pid>, where <pid> is the process id of the JVM
• B.* Log in to the Managed Server VM via SSH* Run the script
  < wlserver_home>/server/bin/setWLSEnv.sh to set the Java classpath* Run java weblogic.Admin - url localhost:<listen port> -username <wluser> -password <wl passwd> GETSTATE to initiate a JVM thread dump, applying appropriate values for the arguments in angle brackets
• C.* Log in to the Managed Server VM via SSH* Run the java -Xcheck: jni MyApp with the verbose : gc option
• D.* Log in to the Managed Server VM via SSH* Use ps to determine the process id (pid) of the Java Process that is running the WebLogic instance* Run: kill-3 <pid> to output the thread dump to the stdout stream of the process

You have created an Oracle Java Cloud Service instance using an Oracle Database as a Service instance named DBaaS.

You have a Java EE application developed and tested in your on-premises environment.
You want to deploy this application to an Oracle Java Cloud Service instance.
Which procedure should you follow to deploy the application to the Oracle Java Cloud Service instance?

• A.Using WLST in the one-premises environment, deploy the application archive directly to the service instance
• B.Using WebLogic Server Administration Console in the on-premises environment, deploy the application archive to the service instance
• C.Using SCP, copy the applications subdirectory from on-premises to the VM running the Managed Server in the Oracle Java Cloud Service instance. Then, stop and start the WebLogic servers in the service instance
• D.Using SCP, copy the applications archive [EAR] file to a directory in the VM running the Administration Server in the Oracle Java Cloud Service instance. Then, using WebLogic Server Administration Console in the service instance, deploy the application
