• Question 72:

  Which is true about the InfiniBand spine switch as it is used in Exalogic? (Choose two)

  A. It is a full 36-port QDR InfiniBand switch.
  B. It is included in quarter, half and full rack configurations
  C. It is only used when wiring multi-rack configurations.
  D. It is used for all InfiniBand switching required between compute nodes and the storage appliance.
  A. It is a full 36-port QDR InfiniBand switch.
  C. It is only used when wiring multi-rack configurations.

  A. 8
  B. 4
  C. 6
  D. 2
  B. 4

  Looking at the front of a full rack Exalogic X2-2 machine, you would see 4 populated InfiniBand switch gateway rack slots?

• Question 74:

  Which of the following are recommended approaches to providing an Oracle database to applications running on Exalogic? (Choose two)

  A. Install the database on the storage appliance and have the runtime environment on the compute servers use it
  B. Install the database on an Exadata machine and use it via Exalogic's InfiniBand network
  C. Install the database on an Exadata machine and use it via Exalogic's 1Gb Ethernet management network
  D. Install the database on a non-Exadata/Exalogic server and access it from Exalogic using the data center's 10Gb Ethernet network
  B. Install the database on an Exadata machine and use it via Exalogic's InfiniBand network
  D. Install the database on a non-Exadata/Exalogic server and access it from Exalogic using the data center's 10Gb Ethernet network

  ---

  The two correct approaches are 1) Install the database on an Exadata machine and use it via Exalogic's InfiniBand network and 2) Install the database on

• Question 75:

  Which two statements are true about the Exalogic X2-2 model?

  A. Exalogic hardware is pre-assembled and delivered in standard 19" 42U rack configuration.
  B. Ethernet connects individual Exalogic internal components as well as connecting externally to additional Exalogic or Exadata racks.
  C. The operating system is pre-installed at the factory.
  D. Each compute node contains a dual processor with 8 cores.
  E. Each compute node utilizes a single solid-state disk to host the operating system images and to act as high-performance swap and storage.

  C. The operating system is pre-installed at the factory.

• Question 76:

  When using OHS and the WebLogic Server proxy plugin with dynamic server lists, what, if any, configuration is required at the OHS tier when adding additional WebLogic Server instances?

  A. OHS must be restarted and up on restart; the dynamic server list will be automatically updated with newly added server(s)
  B. OHS httpd.conf must be updated with the newly added WebLogic Server(s).
  C. Nothing. Newly added WebLogic Server instances are automatically picked up and the plugin is dynamically reconfigured.
  D. The admin server must be restarted when the cluster has been reconfigured. This will, in turn, notify the web tier (OHS).
  A. OHS must be restarted and up on restart; the dynamic server list will be automatically updated with newly added server(s)
