  B. Operating system
  C. JRockit
  D. Firmware for all components
  B. Operating system
  D. Firmware for all components

  ---

  The operating system and firmware for all components are included in the Exalogic Base Image that is installed at the factory.

• Question 62:

  Which Exalogic component has direct network access to the Power Distribution Units (PDUs)? (Choose one)

  A. Cisco management switch
  B. InfiniBand switches
  C. Compute nodes
  D. Storage appliance
  A. Cisco management switch

  ---

  The Cisco management switch has direct network access to the Power Distribution Units (PDUs).

• Question 63:

  What are the redundant features of Exalogic compute nodes? (Choose three)

  A. Power supplies
  B. Cooling fans
  C. InfiniBand network access
  D. ILOM
  E. Motherboards
  A. Power supplies
  B. Cooling fans
  C. InfiniBand network access

  ---

  Cooling fans, InfiniBand network access and power supplies are redundant features.

• Question 64:

  Which is true about Exalogic rack configurations? (Choose one)

  A. An Exalogic machine can grow to include 8 racks.
  B. Exadata racks can be included in a multi-rack Exalogic cluster configuration.
  C. When expanding beyond a single rack, Exalogic becomes a cluster of independent Exalogic machines.
  D. Standard 10Gb Ethernet is used to interconnect multiple racks.
  A. An Exalogic machine can grow to include 8 racks.

• Question 65:

  Which two software components are central to providing the performance benefits delivered by an Exalogic machine?

  A. WebLogic Server
  B. Coherence
  C. SOA Suite
  D. Oracle Database
  E. Oracle VM
  A. WebLogic Server
  B. Coherence

  ---

  Coherence provides replicated and distributed (partitioned) data management and caching services on top of a reliable, highly scalable peer-to-peer clustering protocol. Coherence has no single points of failure; it automatically and transparently fails over and redistributes its clustered data management services when a server becomes inoperative or is disconnected from the network. When a new server is added, or when a failed server is restarted, it automatically joins the cluster and Coherence fails back services to it, transparently redistributing the cluster load. Coherence includes network-level fault tolerance features and transparent soft re-start capability to enable servers to self-heal.

• Question 66:

  When an Exalogic machine is connected to an Exadata machine, which network is used?

  A. Both machines are on the same InfiniBand fabric
  B. Different InfiniBand fabrics
  C. Ethernet over InfiniBand
  D. Management network
  A. Both machines are on the same InfiniBand fabric
