Oracle Solaris Cluster 3.2 System Administrator Certified Professional Exam

Question No: 131 – (Topic 2)

What are the requirements for synchronizing the time-of-day clocks between cluster nodes?

  1. You must use the supplied /etc/inet/ntp.conf.cluster file so that the nodes synchronize only between themselves. You cannot use any other configuration.

  2. You may use any NTP configuration, as long as the clocks on the nodes remain synchronized. The cluster will use /etc/ inet/ntp.conf.cluster file if you have no other configuration.

  3. You must have both a traditional /etc/inet/ntp.conf file for all nodes to synchronize with a trusted source on the public network, and an /etc/inet/ntp.conf.cluster so that the nodes synchronize among themselves.

  4. You must manually modify the /etc/inet/ntp.conf.cluster file and choose a node that will be marked with the server keyword. You must manually mark all other nodes with the client keyword.

Answer: B

Question No: 132 – (Topic 2)

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

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

  1. The global data access traverses the interconnect.

  2. The load balancer sends inbound requests to other nodes over the interconnect.

  3. The cluster needs the interconnect to decide about its cluster membership.

  4. Every application configured in the cluster gains performance benefits from the interconnect.

  5. If a node loses its public network completely, the network traffic is rerouted over the interconnect.

Answer: A,B,C

Question No: 133 – (Topic 2)

You have a two-node cluster that is using scsi-2 disk reservations for your shared storage. All your shared disks support scsi-3 and their default fencing property has not been changed. The cluster#39;s global_fencing property is set to pathcount. The quorum device is 67 and you want 67 to remain as your quorum device. Your shared devices are d3-d10.

Which set of commands will change all disks to use scsi-3?

  1. cluster set -p global_fencing=scsi3 clq refresh d7

  2. cluster set -p global_fencing=scsi3 clq add d6

    clq remove d7

  3. cluster set -p global_fencing=prefer3 clq remove d7

    clq add d7

  4. cluster set -p global_fencing=prefer3 clq add d6

clq remove d7

cldev set -p default_fencing=global d7 clq add d7

clq remove d6

Answer: D

Question No: 134 – (Topic 2)

A cluster administrator should be aware of the capabilities of weak and strong affinities. Which statement is incorrect?

  1. Weak affinities are denoted by one single or – sign.

  2. Weak affinities can be overruled by manual switchovers.

  3. Weak and strong affinities can be applied together on one resource group.

  4. If you defined a weak negative affinity between rg1 and rg2, and this affinity CANNOT be satisfied, rg1 will NOT fail over on a node failure.

Answer: D

Question No: 135 – (Topic 2)

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.)

  1. The cluster RGM will try to start the web resource only if the Oracle resource is already running.

  2. If the RGM restarts the web resource it will then also restart the Oracle resource.

  3. If the RGM restarts the Oracle resource it will then also restart the web resource.

  4. The Oracle resource must be configured in the same resource group as the web resource.

  5. If the web resource fails over, the Oracle resource must be restarted.

Answer: A,C

Question No: 136 – (Topic 2)

Which command is used to offline a resource group named nfsrg?

  1. clrg switch -n node1 nfsrg

  2. cluster offline nfsrg

  3. clrg offline nfsrg

  4. clrsdg disable nfsrg

Answer: C

Question No: 137 – (Topic 2)

Which is an advantage of Sun Cluster 3.2 integration with SMF?

  1. Sun Cluster will always start faster.

  2. Sun Cluster uses SMF to shut down and reboot nodes.

  3. The administrator can start/stop Sun Cluster using the svcadm command.

  4. An application managed by SMF need not be rewritten to be used as a cluster service.

Answer: D

Question No: 138 – (Topic 2)

The cluster administrator has installed a two-node cluster, reset the installmode, and chosen NOT to specify a quorum device.

If the administrator does NOT specify a quorum device, what happens to the cluster the next time one of the nodes is rebooted?

  1. nothing

  2. both nodes panic

  3. the other node panics

  4. the cluster prompts you to assign a quorum device

  5. the cluster automatically assigns a quorum device for you

Answer: C

Question No: 139 – (Topic 2)

Which two types of applications are managed by Sun Cluster 3.2?

  1. global applications

  2. failover applications

  3. scalable applications

  4. client applications

Answer: B,C

Question No: 140 – (Topic 2)

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

  1. Let the cluster scinstall command configure the IPMP group.

  2. Modify the /etc/default/mpathd configuration file if needed.

  3. Configure the IPMP group with ifconfig at the command prompt.

  4. Configure the IPMP group in /etc/hostname.file manually.
