Question #1

You deploy more than one application to the same WebLogic container. The security is set on JavaEE level and all deployed JavaEE applications use the same security roles.

What is your recommendation for an architecture with those requirement

Reveal Solution Hide Solution
Correct Answer: B

Note:

* Types of Security Roles: Global Roles and Scoped Roles

There are two types of security roles in WebLogic Server:

/ A global security role can be used in any security policy. Oracle provides several default global roles that you can use out of the box to secure your WebLogic resource

/ A scoped role can be used only in policies that are defined for a specific instance of a WebLogic resource (such as a method on an EJB or a branch of a JNDI tree). You might never need to use scoped roles. They are provided for their flexibility and are an extra feature for advanced customers.

Incorrect:

Not E: Role mapping is the process whereby principals (users or groups) are dynamically mapped to security roles at runtime. In WebLogic Server, a Role Mapping provider determines what security roles apply to the principals stored a subject when the subject is attempting to perform an operation on a WebLogic resource. Because this operation usually involves gaining access to the WebLogic resource, Role Mapping providers are typically used with Authorization providers.


Question #2

When your WebLogic Server solution needs to be scaled out with additional capacity and you don't want to add additional hardware, which three techniques should you us?

Correct Answer: B, D, E

Question #3

A highly available WebLogic cluster in UNIX is configured for automatic server migration. Node Managed is configured on both machines to start managed servers.

How should you simulate a managed server failure to test whether automatic server migration is working?

Reveal Solution Hide Solution
Correct Answer: A

Note:

* It is recommended that you shutdown WebLogic Server instances through the Administration Console.

* If automatic server migration is enabled, the servers are required to contact the cluster leader and renew their leases periodically. Servers will shut themselves down if they are unable to renew their leases. The failed servers will then be automatically migrated to the machines in the majority partition.


Question #4

A customer claims that while redeploying a web application in the production system all their customers are having to log in again. What do you recommend?

Reveal Solution Hide Solution
Correct Answer: D

Restrictions on Production Redeployment Updates

WebLogic Server can host a maximum of two different versions of an application at one time.

Note:

* When you redeploy a new version of an application, you cannot change:

An application's deployment targets

An application's security model

A Web application's persistent store settings

To change any of the above features, you must first undeploy the active version of the application.

Incorrect:

* (not A)

Production redeployment enables you to update and redeploy an application in a production environment without stopping the application or otherwise interrupting the application's availability to clients. Production redeployment saves you the trouble of scheduling application downtime, setting up redundant servers to host new application versions, manually managing client access to multiple application versions, and manually retiring older versions of an application.

* (not C) Not dependant on whether the application is JRockit or Hotspot.

* (not E)

The production redeployment strategy is supported for:

Standalone Web Application (WAR) modules and enterprise applications (EARs) whose clients access the application via a Web application (HTTP).

Enterprise applications that are accessed by inbound JMS messages from a global JMS destination, or from inbound JCA requests.

All types of Web Services, including conversational and reliable Web Services, but not 8.x Web Services.

Production redeployment is not supported for:

Standalone EJB or RAR modules. If you attempt to use production redeployment with such modules, WebLogic Server rejects the redeployment request. To redeploy such modules, remove their version identifiers and explicitly redeploy the modules.

Applications that use JTS drivers. For more information on JDBC application module limitations, see JDBC Application Module Limitations in Configuring and Managing JDBC Data Sources for Oracle WebLogic Server.

Applications that obtain JDBC data sources via the DriverManager API; in order to use production redeployment, an application must instead use JNDI to look up data sources.

Applications that include EJB 1.1 container-managed persistence (CMP) EJBs. To use production redeployment with applications that include CMP EJBs, use EJB 2.x CMP instead of EJB 1.1 CMP.


Question #5

A common approach to solve application performance issues is to add more hardware. Which two reasons describe why this alone does not always solve performance problems?
