  ---

  The WebLogic Server Management Pack Enterprise Edition provides comprehensive lifecycle management capabilities for middleware software and its underlying hardware that help customers to maximize value of their IT assets, increase the quality of IT services, reduce the cost of managing IT, and meet IT compliance requirements. Key configuration management related features of the pack include the following:

  *

  Automate discovery of configuration items

  *

  Detect configuration changes in real-time and track changes historically

  *

  (B) Compare configurations to reduce "configuration drift" and when undesired differences are detected, synchronize the configurations to make them the same again

  *

  Correlate both real-time and historical configuration changes with performance metrics *(E) Ensure compliance with unique business policies including former BEA Guardian signatures in addition to standards such as Sarbanes-Oxley (SOX) and Payment Card Industry (PCI)

  F: Manage multiple domains centrally

• Question 64:

  Which statement is true about Oracle Enterprise Manager?

  A. It enables users to provision Java EE applications (EAR and WAR files) across WebLogic Server domains.
  B. It enables users to provision APEX applications across WebLogic domains.
  C. It enables users to provision PL/SQL applications across WebLogic Servers domains.
  D. It enables users to provision Java EE applications (EAR and WAR files), but not across a WebLogic Server domain.
  A. It enables users to provision Java EE applications (EAR and WAR files) across WebLogic Server domains.

  ---

  In order to manage Java EE applications across domains, Oracle Enterprise Manager includes the ability to store Java EE applications (i.e. ear and war files) within the software library which can include multiple versions of these applications

  for quick deployments to multiple domains across your enterprise or cloud simultaneously.

  Note:

  Organizations have to be agile in order to compete globally and adapt to changes in business and technology. To achieve this objective, many large IT organizations have implemented flexible integration solutions that include Java EE

  application servers such as Oracle WebLogic Server and Fusion Middleware technologies.

• Question 65:

  When you set up Oracle Enterprise Manager Real Enterprise manager Real user Experience Insight (RUEI), what is needed to establish monitoring of SSL-encrypted HTTP traffic?

  A. Monitoring of SSL traffic is not supported by RUEI.
  B. Installation of an SSL decryption card is required in the RUEI server.
  C. A copy of the SSL key and certificate needs to be uploaded to RUEI.
  D. RUEI should negotiate a private SSL key/certificate pair with each web server.
  C. A copy of the SSL key and certificate needs to be uploaded to RUEI.

  ---

  Adding/Uploading HTTP SSL Keys

  Uploading SSL keys to the system is extremely important if most of your HTTP traffic is based on SSL sessions. Without the SSL keys being available to the system, the Collector will not be able to decrypt the SSL session traffic. In these circumstances, further configuration of cookies, user identification, and application pages would make little sense. Ensure that you upload and activate your HTTPS SSL keys as early on as possible in the configuration process. The management of SSL keys is fully described in the Oracle Real User Experience Insight User Guide.

• Question 66:

  Which statement is true when you perform out-of-place patching with Oracle Enterprise Manager?

  A. It is the recommended approach when your Oracle Home does not follow Oracle Flexible Architecture.
  B. It is the recommended approach when downtime is not a time constraint.
  C. All database are patched simultaneously.
  D. You are not able to retrieve the path recommendations because you are not connected to the network.
  E. Your original Oracle Home is available for recovery operations.
  E. Your original Oracle Home is available for recovery operations.

  ---

  Using this mechanism [out-of-place patching] means that the only downtime will take place when the Databases from the previous Home are switched to run from the new Home. If there is any issue with the Database patch, you can switch back to the previous unpatched Home since it is still available. So, patch rollback is a lot faster. Note: A new mechanism for patching has been provided in Oracle Enterprise Manager Cloud Control 12c, known as Out of Place Patching. This is now the recommended method and creates a new Oracle Home, which is then patched while the previous Home is still operational. All this is done using an out-of-box Deployment Procedure in Enterprise Manager.

• Question 67:

  Which statement is true about Oracle Enterprise Manager Cloud and Virtualization management?

  A. It can perform live migration of the Hypervisor.
  B. It can perform live migration of ANSI-compliant Virtual Machines.
  C. It can perform live migration of Oracle VMs.
  D. It can perform live migration of storage pools.
  C. It can perform live migration of Oracle VMs.

  ---

  Live Migration

  To take advantage of Enterprise Manager Ops Center's live migration capability, the server pool must be configured with the following:

  *

  Oracle VM for SPARC 2.1 or higher (2.2 is recommended)

  *

  The SPARC T4 server has a minimum firmware level of 8.1.1 (8.2.0f or higher is recommended)

  *

  All networks and storage libraries are physically presented to all servers in the server pool as well as being defined in Enterprise Manager Ops Center

  *

  All CDOMs have network connectivity to all other CDOMs in the server pool.

  *

  The agent on the CDOMs is must be online.

• Question 68:

  Which three activities can you perform by utilizing the monitoring templates in Oracle Enterprise Manager?

  A. Apply standardized monitoring settings across managed targets.
  B. Create once, and then apply monitoring and policy settings as needed.
  C. Apply a template only to targets of the same type.
  D. Clone templates across VMs.
  E. Export templates directly to tape.
  A. Apply standardized monitoring settings across managed targets.
  B. Create once, and then apply monitoring and policy settings as needed.
  C. Apply a template only to targets of the same type.

  ---

  Monitoring templates simplify the task of standardizing monitoring settings across your enterprise by allowing you to specify the monitoring settings once and apply them to your monitored targets. This makes it easy for you to apply specific monitoring settings to specific classes of targets throughout your enterprise. For example, you can define one monitoring template for test databases and another monitoring template for production databases.

• Question 69:

  Identify two true statements about the setup and use of identity management within Oracle Enterprise manager.

  A. Credentials are used to access targets that are monitored and managed by Oracle Enterprise Manager.
  B. Repository-Base Authentication is the default authentication.
  C. Single Sign-On Authentication is the default authentication.
  D. Credentials are used as the root of the data masking key.
  E. Using the SCOTT/TIGER identify, you can demonstrate but not configure Oracle Enterprise Manager.
  A. Credentials are used to access targets that are monitored and managed by Oracle Enterprise Manager.
  B. Repository-Base Authentication is the default authentication.

  ---

  B: You can also monitor the performance of the Oracle Identity Manager Repository and keep track of the number of newly provisioned/created/deleted/disabled/locked users, as well as the number of newly initiated requests.

• Question 70:

  C. Throughput
  D. Faults
  E. SQL executes
  A. Availability
  C. Throughput
