QUESTION NO: 1
You have created a service instance in Oracle Java Cloud Service. You have full access to the underlying infrastructure and product software. You access services and resources on a virtual machine by using a Secure Shell utility such as PuTTY or OpenSSH.
What three things should you do to run WLST commands local to the WebLogic Administration Server virtual machine? (Choose three)

A. Create an SSH tunnel between your local machine and the WebLogic Administration Server virtual machine B. Get the SSH private key corresponding to the public key used when the service instance was created C. Obtain the IP address of the WebLogic Administration Server virtual machine D. Open an SSH session to the WebLogic Administration Server virtual machine E. Create a new SSH private/public key pair

Correct Answer: B,C,D

QUESTION NO: 2

QUESTION NO: 3
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?

A. The WebLogic Administrator user name and password should be used to disable or enable the load balancer through the Oracle Traffic Director Administration Console B. The password for the virtual machine opc user or oracle user can be changed through the Oracle Compute Cloud Service console C. The oracle user cannot be used to log in to the WebLogic Administration Server virtual machine D. 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

QUESTION NO: 7
You are assisting on Oracle Java Cloud Service (JCS) customer who has reported slow response times in their production system. The customer has provided you with details of the number of concurrent users, the number and size of application requests, their data volumes, and their desired CPU utilization. You have only a limited time window during which you can change the production environment.
What is the optimal order of priority for your initial remedial actions?

A. 1. Use the WebLogic Diagnostic Framework to gather performance metrics2. Tune the WebLogic environment based on diagnostic results3. Monitor application performance in JCS Control Console and Fusion Middleware Control console B. 1. Use Oracle Fusion Middleware Control to configure a dashboard with custom metrics2. Use Java Mission Control to monitor JVM heap usage3. Take Java Threads dumps and search for locked threads C. 1. Log in to the JCS virtual hosts and use Linux command line tools to monitor performance2. Change the Linux kernel parameters to improve performance3. Apply patches to the OS and the WebLogic Server D. 1. Monitor system metrics such as utilization of disc/CPU, network data transfers, persistent store writers, and logging volume2. Locate or identify bottlenecks in the application, database, and WebLogic configuration3. Analyze the results, suggest changes that are likely to give the maximum benefit, and then prioritize configuration changes based on the analysis. E. 1. Configure an identically sized JCS environment in an alternate data center2. Deploy the customer application to the new environment3. Implement the Oracle JCS tuning methodology to compare the results
