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
A. Combine all applications into a single one.
B. Define global roles on the WebLogic Domain level.
C. Use Ms Active Directory to keep the roles there.
D. Use Oracle Identity and Access Management solution to simplify the management.
E. Keep role mapping in the external WebLogic Role Mapped developed for that solution.
Answer: B
Explanation:
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?
A. Assign more than one managed server to a physical hardware that allows better CPU
utilization.
B. Assign more than one application to one managed server to better utilize threads within a single
JVM process.
C. Assign the same application to more than one managed server to load balance requests
between servers.
D. Assign the same heap size to the managed server across the cluster for easier control of
memory footprint
E. Create a virtualized environment with hypervisor for an easier solution
Answer: B,D,E
Explanation:
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?
A. Shut down the managed server from the WebLogic console.
B. Shut down the managed server using the WLST command through Node Manager.
C. Run “kill -9” once to kill the managed server process.
D. Run “kill -9” to kill the managed server process, and run “kill -9” one more time if the managed
server is restarting.
Answer: A
Explanation:
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?
A. Sessions can’t be preserved when redeploying applications. The customer needs to consider
redeployment during late nights when the traffic is low.
B. Change the flag responsible for the development mode of their environment. In the production
mode, all sessions are preserved while redeploying application.
C. Change Hotspot to JRockit. Sessions can’t be preserved on HotSpot when redeploying
application.
D. Use flag -version when redeploying the application. This will switch on the Side By Side
deployment feature and preserve existing sessions.
E. Open a service request with Oracle Support. This is unexpected behavior. Sessions are
preserved without any extra settings.
Answer: D
Explanation: 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?
A. There may be a bottleneck in the application that additional hardware would not solve.
B. Adding more hardware is costly and time consuming.
C. Adding hardware at the application layer may place additional load on an already overloaded
database, network appliance, or storage system.
D. Adding more hardware may introduce new configuration requirements that need to be tested.
