  Step 1: Oracle Virtual Assembly Builder

  Oracle Virtual Assembly Builder makes it possible for administrators to quickly configure and provision entire multi-tier application topologies onto virtualized and cloud environments. It provides a framework for capturing the configuration of

  existing software components and packaging them as self-contained building blocks known as appliances. These appliances can then be easily connected to form application blueprints known as assemblies. This innovative approach makes

  it practical for complex enterprise applications to easily be customized and provisioned in their entirety with minimal to no manual intervention onto virtualized and cloud environments.

  *

  Step 2 Software Library

  The Software Library Administration console allows you to configure and administer Software Library. To start using the Software Library, you must add at least one upload file storage location (OMS Shared location, or OMS Agent location)

  on the host where the OMS is running. A storage location in Software Library represents a repository of files, these files are either uploaded by Software Library, or generated and saved by some user-owned process.

• Question 18:

  Which three Oracle WebLogic Server Change and Compliance Management capabilities are available in Oracle Enterprise Manager?

  A. Identifying the host practices related to the Weblogic Server configuration.
  B. Tracking application security compliance violations in Web logic Server
  C. Tracking networking compliance violations
  D. Ensuring Sarbanes-Oxley and PCI compliance across the stack
  E. Ensuring WebLogic license compliance
  A. Identifying the host practices related to the Weblogic Server configuration.
  B. Tracking application security compliance violations in Web logic Server
  D. Ensuring Sarbanes-Oxley and PCI compliance across the stack

  ---

  A: Examples of information collected at regular intervals include:

  / Oracle WebLogic Server software installations, including applied patches / Oracle WebLogic Server configuration parameters (e.g. ports, JVM information, JDBC and JMS resources, startup and shutdown classes) and configuration files /

  Operating system patches, kernel parameter settings, and installed packages / Hardware components including CPU, memory, storage, and network devices

  B: Many performance degradation issues in production application environments occur due to unauthorized configuration change. Organizations using Oracle WebLogic Server and other Application Servers routinely struggle with managing

  configurations and enforcing compliance standards across all of their server deployment. Oracle Enterprise Manager provides comprehensive configuration management capabilities that help customers maximize value of their IT assets,

  increase the quality of IT services, reduce the cost of managing IT, and meet IT compliance requirements.

  D: Ensuring compliance with standards such as SOX (Sarbanes-Oxley), ITIL, and PCI, as well as with unique business standards, is a challenge. Oracle Enterprise Manager ships with several predefined policies for Oracle WebLogic Server

  and also enables users to define their own specific policies and groups to quickly demonstrate compliance with various regulations and standards.

  Note:

  / Compare the consolidation scenarios you create to determine which consolidation strategy best meets your requirements.

  Your objective is to:

  *

  Match source server resource requirements with destination servers best able to meet those requirements

  *

  Fit source server requirements with each destination server's available resources as tightly as possible, so you can get maximum usage of destination server capacity

  *

  Optionally balance the source server workload across all available destination servers Reference: Oracle Enterprise Manager Cloud Administration Guide , Using Consolidation Planner

• Question 20:

  Which three components are part of the Oracle Enterprise Manager infrastructure?

  A. Oracle Management Service (OMS)

  D. Real User Experience Insight
  E. Repository Database
  F. Oracle Universal Installer
  A. Oracle Management Service (OMS)
  B. Management Agent
  E. Repository Database

  ---

  A: The Oracle Management Service (OMS) provides the services used to coordinate the storage of management information and the automation of management activities for all entities managed in the network. It also includes facilities for serving the web-based user interface, which is the Cloud Control console.

  B: The Management Agent is the lightweight process that acts as a proxy for Enterprise Manager on the various hosts in the network where entities that Enterprise Manager manages are located. It communicates with the OMS to collect and deliver monitoring information and to coordinate management activities executed against the management entities.

  E: The Management Repository is the Oracle Database that stores all important management information for the entities managed by Enterprise Manager. The Oracle Management Service (OMS) uses the Management Repository to store and retrieve key information, such as monitoring data.
