• Question 151:

  Which command will shut down all nodes of the cluster?

  A. init 0
  B. shutdown -y -g0
  C. cluster shutdown -y -g0
  D. scadmin shutdown -y -g0
  C. cluster shutdown -y -g0

• Question 152:

  How is a disk repartitioned when it is added to a diskset?

  A. The entire drive is mapped to slice 0.
  B. A small portion of the drive is mapped to slice 3 and the remainder to slice 4.
  C. A small portion of the drive is mapped to slice 7 or 6 and the remainder to slice 0.
  D. The drive is automatically converted to an EFI label regardless of the size of the drive.
  C. A small portion of the drive is mapped to slice 7 or 6 and the remainder to slice 0.

• Question 153:

  When using ZFS within the cluster, the cluster administrator should mirror the data across controller paths. Each node should have at least two separate paths to shared storage. How does the cluster administrator ensure that the paths are identical on each node so the ZFS pool can fail over without any problems?

  A. Do nothing. Even if the path names are different on each node, zpools can still fail over.
  B. ZFS automatically renames disk path names to ensure that they are identical on each node.
  C. Use the DID paths.
  D. Manually ensure that each controller has the same number on each node.
  A. Do nothing. Even if the path names are different on each node, zpools can still fail over.

• Question 154:

  Which three pieces of information are required to perform an interactive Sun Cluster configuration using scinstall while choosing the automatic quorum configuration? (Choose three.)

  A. name of the cluster
  B. name of all the nodes
  C. name of all logical hostnames
  D. DID number for the quorum device
  E. name of the transport adapters on at least the first node
  A. name of the cluster
  B. name of all the nodes
  E. name of the transport adapters on at least the first node

• Question 155:

  The scinstall command can perform automatic quorum configuration. In which case must you manually configure a quorum device if you want one?

  A. any cluster
  B. two-node cluster
  C. single-node cluster
  D. any cluster with more than two nodes
  D. any cluster with more than two nodes

• Question 156:

  Given this output from the cldg show command: Device Groups === Device Group Name:ds1 Type:SVM fallback: false

  Node List:node1, node2

  preferenced:true numsecondaries:1 diskgroup name:ds1 Which command would enable the fallback property?

  A. cldg set -p failback=true ds1
  B. cldg set -p failback=enable ds1
  C. metaset -s ds1 set failback=true
  D. cldevicegroup set failback=true ds1
  A. cldg set -p failback=true ds1

• Question 157:

  You have two local (non-shared) disks on a cluster node. You put one local metadb replica on one disk and two local metadb replicas on the other disk. What will happen if later the disk with the two replicas fails?

  A. You are guaranteed that the node stays up and running, and can reboot. As long as Solaris Volume Manager can find one valid copy of the configuration, the node will stay up.
  B. You are guaranteed to stay up and running. However, if you reboot, you may have to manually delete the broken metadb replicas before being able to join the cluster.
  C. When Solaris Volume Manager discovers you have less than 50% of your local metadbs remaining, it will fail immediately.
  D. When Solaris Volume Manager discovers you have less than 50% of your local metadbs remaining, it will prompt you to fix the broken ones and you can stay operational without rebooting.
  C. When Solaris Volume Manager discovers you have less than 50% of your local metadbs remaining, it will fail immediately.

• Question 158:

  A system administrator has received the Java ES distribution as a two-CD set, and wishes to configure an NFS server to use as an install server for Sun Cluster 3.2. What is the correct procedure?

  A. Mount and share each CD from a separate server.
  B. This is NOT possible, only the DVD distribution can be used in this case.
  C. Create a working directory, share it using NFS, and combine the contents of both CDs into it using the cpio command.
  D. Mount the first CD and share it using NFS. When prompted by the installer, unshare and unmount the CD, and repeat the process with the second CD.
  C. Create a working directory, share it using NFS, and combine the contents of both CDs into it using the cpio command.

• Question 159:

  You want to suspend a resource group to perform application maintenance. Which statement is incorrect regarding this task?

  A. The state of an application resource is reported as offline if the application administrator stops the application manually.
  B. You can still enable or disable a resource with the clrs command while the resource group is suspended.
  C. When the node which masters the resource group fails, the resource group will not be failed over to another node.
  D. If the entire cluster reboots, the suspended resource group will remain offline.
  A. The state of an application resource is reported as offline if the application administrator stops the application manually.

• Question 160:

  Which two statements identify the requirements for installing VxVM 4.x in Sun Cluster? (Choose two.)

  A. You must have a rootdg configured on all nodes.
  B. VxVM must be installed on all nodes physically connected to the shared storage.
  C. All disks must get partitioned using the Cross-Platform Data Sharing (CDS) layout.
  D. The vxio major number assigned in /etc/name_to_major file must be identical on all nodes.
  E. All disks must be traditionally partitioned using separate Solaris OS disk slices for the private region and the public region.
  B. VxVM must be installed on all nodes physically connected to the shared storage.
  D. The vxio major number assigned in /etc/name_to_major file must be identical on all nodes.
