• Question 103:

  A service engineer is at a customer site to install a two-node Sun Cluster 3.2 cluster on SPARC systems, and discovers that the customer has no shared storage available. What should the engineer do?

  A. Ask the customer to buy storage, since this is NOT a supported configuration.
  B. Try to set up a cluster using an XS4 Solaris node, to be used as third node just to have enough votes.
  C. Ask the customer to provide a Solaris server (SPARC or X64) to be used as quorum server and verify with the customer that the application does not require shared data.
  D. Use the Terminal Concentrator as a quorum device and install the cluster, because the customer application is purely compute-based and does NOT need shared data for the application.
  C. Ask the customer to provide a Solaris server (SPARC or X64) to be used as quorum server and verify with the customer that the application does not require shared data.

• Question 104:

  You have an application resource web-res representing a web resource, and you set the property Resource_dependencies_restart=ora-server-res to represent that the web resource is dependent on an Oracle resource. Which two are true? (Choose two.)

  A. The cluster RGM will try to start the web resource only if the Oracle resource is already running.
  B. If the RGM restarts the web resource it will then also restart the Oracle resource.
  C. If the RGM restarts the Oracle resource it will then also restart the web resource.
  D. The Oracle resource must be configured in the same resource group as the web resource.
  E. If the web resource fails over, the Oracle resource must be restarted.
  A. The cluster RGM will try to start the web resource only if the Oracle resource is already running.
  C. If the RGM restarts the Oracle resource it will then also restart the web resource.

• Question 105:

  With Sun Cluster 3.2 it is possible to specify typical or custom installation.

  Which two items must you provide to scinstall when perfoming a typical configuration? (Choose two.)

  A. cluster name
  B. /globaldevices size
  C. cluster transport adapters
  D. quorum disk name
  E. cluster interconnect network address and netmask
  F. number of cluster interconnects to be used and switch configuration
  A. cluster name
  C. cluster transport adapters

• Question 106:

  In a two-node cluster, you specifically want to assign the shared disk with the highest c#t#d#as the quorum device. Which two methods will allow you to get this disk properly assigned as the quorum device? (Choose two.)

  A. Specify which disk you want assigned as the quorum device as you run scinstall.
  B. Choose during scinstall to disable automatic quorum device selection. Once both nodes are booted into the cluster, use clsetup to choose the quorum device and to reset installmode.
  C. Allow scinstall to automatically configure the quorum device. Once both nodes are booted into the cluster, use clsetup first to add a second quorum device and then to remove the original one.
  D. Allow scinstall to automatically configure the quorum device. Once both nodes are booted into the cluster, use clsetup first to remove the original quorum device and then to add your chosen one.
  B. Choose during scinstall to disable automatic quorum device selection. Once both nodes are booted into the cluster, use clsetup to choose the quorum device and to reset installmode.
  C. Allow scinstall to automatically configure the quorum device. Once both nodes are booted into the cluster, use clsetup first to add a second quorum device and then to remove the original one.

• Question 107:

  When you design the network redundancy for a cluster node, you have to understand the key requirements of IPMP. Which statement is incorrect?

  D. Solaris 10 must have test addresses configured in an IPMP group with more than one adapter.

• Question 108:

  C. clnas set -p
  D. clq add -t netapp -u root

• Question 109:

  Your customer has chosen to use Solaris Volume Manager for their shared disks. A diskset named ds1 has already been created with node1 and node2 being able to master the diskset. The customer would like to build a mirrored volume to contain their application data. The diskset ds1 contains two 36 Gbyte disk drives using did devices d4 and dS. The customer would like to use as volume names d101 and d102 as the submirrors and d100 as the mirror.

  Which sequence of commands will accomplish this task?

  A. metainit d101 1 1 /dev/did/rdsk/d4s0 metainit d102 1 1 /dev/did/rdsk/d8s0 metainit d100 -m d101 metattach d100 d102
  B. metainit d101 1 1 /dev/did/rdsk/d4s0 metainit d102 1 1 /dev/did/rdsk/d8s0 metainit d100 -m d101,d102
