When creating an Oracle Java Cloud Service instance by using the REST API, you pass the following JSON document with your request:

The service instance is provisioned successfully and the sample application is automatically deployed.

Which port is valid for accessing the sample application over the HTTPS protocol?

8989
80
9001
8001
7002
7001
8002
443

Correct answer: B

Explanation:

Reference https://docs.oracle.com/en/cloud/paas/java-cloud/jscug/enabling-http-access-oracle-java-cloud-service-instance.html#GUID-A33B34F9-C91A-429F-92E3-ED78BF03AC87

The on-premises Java EE application that you are planning to migrate to Oracle Java Cloud Service instance contains JMS (Java Messaging Service) resources:

hwjms_srv [a JMS server],
hwjms_mod [a JMS module], and
hwjms_agent [a Store and Forward agent]

What should you do the first time you migrate these JMS resources?

Pack the JMS resource files at the on-premises environment and unpack the files in the Oracle Java Cloud Service instance
Copy the WLS domain configuration folder from the on-premises environment to the Oracle Java Cloud Service instance
Create the JMS resources in the Oracle Java Cloud Service instance
Create a WLS cluster in the Oracle Java Cloud Service instance and add the Managed Servers from the on-premises WLS domain

Correct answer: D

Explanation:

You have been provisioned with a Java Cloud Service instance. The WebLogic Server domain in this instance has an Administration Server and two Managed Servers. The Managed Servers are configured into a cluster.

You plan to create an additional security realm to create and test custom security policies in the WebLogic Server domain of this instance.

How many security realms can be active in a WebLogic Server domain of the Java Cloud Service instance?

three: one for the Administration Server and one for each Managed Server
two: one for the Administration Server and one for the cluster
four one for the domain and one for each WebLogic Server
one: for the domain only

Correct answer: B

You want to deploy an application to an Oracle Java Cloud Service instance. In this case, you must create an SSH tunnel to a port on the appropriate virtual machine (VM).

Which statement is true?

Specify the public IP address of the Managed Server
Specify port 22 as the local port
Specify the private key corresponding to the public key used in creating the service
Use a Linux SSH client rather than a Windows tool to create the tunnel

Correct answer: C

Explanation:

You are migrating an automobile service records application from your on-premises environment to an Oracle Java Cloud Service instance. In this application, you are using JMS services to orchestrate service records processing.

To migrate the JMS resources to the Oracle Java Cloud Service instance, which procedure should you follow at the source [on-premises] environment?

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

The Coherence feature is optional in Oracle Java Cloud Service.

Which is a true statement about the Coherence feature?

The Coherence feature is enabled only during the initial creation of a service instance in Oracle Java Cloud Service
Then the Coherence feature is enabled, only the data tier cluster is associated with the Coherence cluster
The data tier cluster is scaled independently of the application tier cluster using cloud tooling or the REST API.
The data tier cluster cannot be removed after the Coherence feature is enabled

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 have created an Oracle Java Cloud Service instance and you want to take advantage of the capabilities of the Node Manager.

Which two statements about using Node Manager in Oracle Java Cloud Service are true? (Choose two)

You can migrate servers from a failed machine to another machine
You can stop and start the Administration Server and Managed Servers
You can start and stop the VM

Correct answer: CD
