  A. The node will increase the size of the private region on the disks within the disk group.
  B. The node physically reads and writes data to the drives within the disk group.
  C. The node waits until all mirrored data is in sync before writting data to the disk group.
  D. The node can voluntarily give up ownership of the disk group by deporting the disk group.
  B. The node physically reads and writes data to the drives within the disk group.
  D. The node can voluntarily give up ownership of the disk group by deporting the disk group.

• Question 114:

  An administrator is deciding whether to use a global file system or a failover file system for an application. Which is a good reason to use a global file system?

  A. ZFS (and its new features) can be used as a global file system.
  B. A global file system can be accessed by all nodes of the cluster simultaneously.
  C. Writes to a global file system can have a performance benefit over failover file systems
  D. You can only configure a shared copy of application binaries in a global file system.
  B. A global file system can be accessed by all nodes of the cluster simultaneously.

• Question 115:

  If a cluster which uses a quorum server is operating normally, and the system where the quorum server process is running is rebooted, what steps must a system administrator take?

  A. Remove and re-add the quorum device.
  B. None, the cluster will automatically reconnect.
  C. Add the quorum device again using the clq add command.
  D. Force a cluster reconfiguration event in order to connect to the new process.
  B. None, the cluster will automatically reconnect.

• Question 116:

  Which two statements describe reasons for using the Sun Cluster Manager graphical application to manage the cluster (Choose two.)?

  A. It shows live status of the cluster by highlighting faulted components, without the user having to manually refresh the display.
  B. It can draw pictures of some of the hardware and other configured elements of your cluster.
  C. It has its own authentication mechanism separate from the node on which it is running. Users can log in with user names different than those on the node, and thus be authorized to accomplish tasks that they cannot accomplish on the command line.
  D. It contains wizards to guide you through properly configuring IPMP on your public network.
  A. It shows live status of the cluster by highlighting faulted components, without the user having to manually refresh the display.
  B. It can draw pictures of some of the hardware and other configured elements of your cluster.

• Question 117:

  Every multi-node cluster has to have private interconnect hardware.

  Which three items identify how the cluster uses the interconnect? (Choose three.)

  A. The global data access traverses the interconnect.
  B. The load balancer sends inbound requests to other nodes over the interconnect.
  C. The cluster needs the interconnect to decide about its cluster membership.
  D. Every application configured in the cluster gains performance benefits from the interconnect.
  E. If a node loses its public network completely, the network traffic is rerouted over the interconnect.
  A. The global data access traverses the interconnect.
  B. The load balancer sends inbound requests to other nodes over the interconnect.
  C. The cluster needs the interconnect to decide about its cluster membership.

• Question 118:

  What is the minimum number of nodes required to make a highly available cluster?

  A. One
  B. Two
  C. Four
  D. Eight
  B. Two

• Question 119:

  B. For as many clusters as you like.
  C. From two to 16 clusters maximum.
  D. None, you cannot use a server as a quorum device.
  B. For as many clusters as you like.

• Question 120:

  Sun Cluster 3.2 requires an IPMP configuration for a logical host resource. Which action does NOT lead to a persistent IPMP configuration?

  A. Let the cluster scinstall command configure the IPMP group.
  B. Modify the /etc/default/mpathd configuration file if needed.
  C. Configure the IPMP group with ifconfig at the command prompt.
  D. Configure the IPMP group in /etc/hostname.file manually.
  C. Configure the IPMP group with ifconfig at the command prompt.
