Q22. Which of the following statements best describes how the deployment supports closed-loop governance? 

A. The Metadata Repository is integrated with the operational systems to link operational metrics to the assets to ensure that the assets perform asintended. 

B. The Metadata Repositories deployed in each environment are chained to share asset usage information. 

C. A closed-loop governance framework is deployed on a clustered server to monitor the governance activities. 

D. Production systems are integrated to the developer desktops to validate the requirements against the implemented code. 

Answer: B,C 

Explanation: SOA Software’s Policy Manager and Service Manager combine to form a comprehensive closed-loop SOA Governance solution. 

Closed loop means: 

* Defining and managing actionable policies in a governance solution at design-time 

* Enforcing these policies via deep integration with a management solution at run-time 

* Auditing that these policies are being enforced 

* Using industry standards (WS-Policy, WS-MEX) where appropriate for information exchange Closed loop infrastructure enables demand and Value Management 

* Collect performance, usage and exception statistics at run-time 

* Track these statistics via the governance solution 

* Use live, audited information to drive value-based decisions about the effectiveness of different services and organizations 

* Provide developers with up to the minute information about a service in runtime to inform their decisions about which services to use 

* Manage supply and demand to ensure maximum efficiency and benefit from SOA 

The products share a common registry and metadata repository to ensure seamless integration and offer active governance. Closed-loop governance will: 

* Ensure defined policies are enforced ** When you define a policy for a service you have to KNOW categorically that it is being enforced ** Generate audit trails for run-time and design-time policy compliance 

* Measure the real-world value of SOA ** Not just theoretical value ** How many applications are using each service, and how much are they using it ** NOT how many applications have asked to use a certain capacity of each service 

* Manage, monitor and control relationships between consumers and providers ** Enforced contracts ** Capacity planning Change management 

The diagram below shows the relationships between SOA governance, security and management, demonstrating how SOA Policy Management forms a closed loop of policy, metrics, and audit. 

Q23. Which of the following are capabilities required for the Integration subsystem of the Oracle Reference Architecture Management and Monitoring Framework? 

A. Data Exchange

Q27. What does the Identity Asserter do in a J2EE framework? 

A. It informs the container of the client identity of an inbound request. 

B. It Inserts identity into Web Service credentials used for outbound service requests. 

C. It determines a user's identity based on a given set of security roles and asserts it to the container. 

D. It resolves Identity conflicts when multiple LDAPs are used. 


Explanation: Like the Authenticator, theIdentity Assertersecurity provider uses Oracle Access Manager authentication services to validate already-authenticated Oracle Access Manager users using the ObSSOCookie and to create a WebLogic-authenticated session. 

Note: If authentication is successful, the identity asserter creates a Subject, which is used to identify the user. Actions performed by the user will be associated with the Subject so that the caller's identity will be known. If outbound requests are made by the business logic, identity can be included by the container based on the Subject. 

Q28. Which three primary components form IT Strategies from Oracle (ITSO)? 

A. Enterprise Technology Strategies 

B. Maximum Availability Architecture

Q29. For a large heterogeneous environment with a large number of hosts requiring scalability and efficiency, what is the best strategy for deployment of Oracle Enterprise Manager? 

A. Use a centralized control with persistent connections to all agents to pull data. 

B. Use multiple semi-autonomous agents collecting information and periodically relaying it to a central repository. 

C. Use multiple Instances of Oracle Enterprise Manager to maximize performance. 

D. Use centralized alert filtering. 


Explanation: Oracle Enterprise Manager 11g Grid Control has the ability to scale for hundreds of users and thousands of systems and services on a single Enterprise Manager implementation. Can use two instances of Oracle Enterprise Manager for large deployments (10000 clients or more). The architecture for Oracle Enterprise Manager 10g Grid Control exemplifies two key concepts in application performance tuning: distribution and parallelization of processing. Each component of Grid Control can be configured to apply both these concepts. The components of Enterprise Manager Grid Control include: 

* The Management Agent - A process that is deployed on each monitored host and that is responsible for monitoring all services and components on the host. The Management Agent is also responsible for communicating that information to the middle-tier Management Service and for managing and maintaining the system and its services. 

* The Management Service - A J2EE Web application that renders the user interface for the Grid Control Console, works with all Management Agents to process monitoring and jobs information, and uses the Management Repository as its data store. 

* The Management Repository - The schema is an Oracle Database that contains all available information about administrators, services, and applications managed within Enterprise Manager.
