Use the WLS Administration Console and note the JMS configuration information from the on-premises environment
Use the zip utility and package the managed server files in the domain in the on-premises environment
Use the database export [or expdp] utility to export JMS resources in the on-premises environment
Use the WLS pack utility to pack the JMS resources in the one-premises environment

Correct answer: B

You are tasked with tuning your Oracle Java Cloud Service application environment.

Identify the correct sequence of activities for Oracle’s recommended performance tuning methodology.

Configure the Oracle Java Cloud Service compute shape and clusters, set up Oracle Database Cloud – Database as a Service, develop and deploy application, configure a Continuous Integration environment, and develop performance test cases
Understand performance objectives, measure performance metrics, locate bottlenecks in the system, minimize impact of bottlenecks, and achieve performance objectives
Tune the EJBs and message-driven beans, the JDBC data source, the WebLogic JMS components, the Resource Adapters, the Web Applications, and the Web Services
Review the Oracle Java Cloud Service Console metrics, the Fusion Middleware Control metrics, the WebLogic Server console diagnostics, the Java Mission Control flight recordings, and the operating system performance monitoring console.
Tune the database, the application, the Weblogic Server configuration, the JVM, and the operating system

Correct answer: D

You created a Database Cloud Service instance. Now you are attempting to create an Oracle Java Cloud Service instance. However, when you reach the main Oracle Java Cloud Service configuration screen, you find that your database instance is not available for selection. This prevents creation of the JCS instance. You check and determine that your database instance is running.

What is preventing creation of your Oracle Java Cloud Service instance?

Your subscription to the Database Cloud Service has expired
The public key that you provided to the JCS instance is unable to establish an SSH connection to the database instance
You selected an incompatible combination of WebLogic Server and Database Versions
When creating the Database Cloud Service instance, the backup storage configuration was not configured to “Both local and Cloud Storage”

Upon initial creation of a service instance in Oracle Java Cloud Service, administrative user accounts for the WebLogic Server domain and the underlying Compute Cloud Service virtual machines are automatically created.

Which statement about the administrative accounts is true?

The password for the virtual machine opc user or oracle user can be changed through the Oracle Compute Cloud Service console
For the opc user to become root on the WebLogic Administration Server virtual machine, the private key corresponding to the public key that was used when the service instance was created should first be attached to the virtual machine
The WebLogic Administrator user name and password should be used to disable or enable the load balancer through the Oracle Traffic Director Administration Console
The oracle user cannot be used to log in to the WebLogic Administration Server virtual machine
