• Question 2:

  Your customer has chosen to use Solaris Volume Manager for the 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.

  The customer would like to create two soft partitions named d10 and d11, with d10 5gb and d11 10gb in size.

  Which sequence of commands will accomplish this task?

  A. metainit -s ds1 d101 1 1 /dev/did/rdsk/d4s0 metainit -s ds1 d102 1 1 /dev/did/rdsk/d8s0 metainit -s ds1 d100 -m d101 metattach -s ds1 d100 d102 metainit -s ds1 d10 -p d100 5g metainit -s ds1 d11 -p d100 10g
  B. metainit d101 1 1 /dev/did/rdsk/d4s0 metainit d102 1 1 /dev/did/rdsk/d8s0 metainit d100 -m d101 metattach d100 d102 metainit d10 -p d100 5g metainit d11 -p d100 10g
  C. metainit d101 1 1 /dev/did/rdsk/d4s0 metainit d102 1 1 /dev/did/rdsk/d8s0 metainit d100 -m d101,d102 metainit d10 -p d100 5g, d11 -p d100 10g
  D. metacreate -s ds1 d101 /dev/did/rdsk/d4s0 metacreate -s ds1 d102 /dev/did/rdsk/d8s0 metamirror -s ds1 d100 d101,d102 metaspart -s ds1 d10 d100 5g metaspart -s ds1 d11 d100 10g
  A. metainit -s ds1 d101 1 1 /dev/did/rdsk/d4s0 metainit -s ds1 d102 1 1 /dev/did/rdsk/d8s0 metainit -s ds1 d100 -m d101 metattach -s ds1 d100 d102 metainit -s ds1 d10 -p d100 5g metainit -s ds1 d11 -p d100 10g

• Question 3:

  Your customer has just successfully executed the following commands:

  vxassist -g oradg make oravol 3g layout=mirror cldg sync oradg newfs /dev/vx/rdsk/oradg/oravol mkdir /oracle Now the customer is trying to mount the file system globally and gets this error message after typing the commands: mount -o global /dev/vx/dsk/oradg/oravol /oracle mount: /dev/vx/dsk/oradg/oravol or/oracle, no such file or directory The customer checks the device file and the directory on that node and determines that they do exist. What has the customer forgotten to check?

  A. The command was typed incorrectly.
  B. The mount point does not exist on all nodes.
  C. The file /dev/vx/dsk/oradg/oravol does not exist on all nodes.
  D. The customer has forgotten to synchronize the new volume information.
  B. The mount point does not exist on all nodes.

• Question 4:

  When are switches required for private interconnects?

  A. when using ZFS
  B. when using Solaris Zones
  C. when configuring a single-node cluster
  D. when a cluster has more than two nodes
  D. when a cluster has more than two nodes

• Question 5:

  You set up your cluster using the default 172.16.x.x range for the cluster transport. Yet these same IP addresses are in use on machines in a department that you need to access across the public network. What kind of problem will you experience?

  A. Your cluster nodes will refuse to communicate across the private network.
  B. Your public network adapters will be marked as FAILED.
  C. Communication to the machines using 172.16.x.x on the public network fails, because your cluster nodes wil want to route this traffic across the private network.
  D. You will remain free of problems. It is perfectly acceptable to use a range of IP addresses on your private networks that conflicts with other machines on your public network.
  C. Communication to the machines using 172.16.x.x on the public network fails, because your cluster nodes wil want to route this traffic across the private network.

• Question 6:

  You are talking to a customer on the phone and they need support. One of the first things you want to know is the version of Sun Cluster that they are running. Which command do they use in order to determine the cluster version?

  A. cluster show
  B. cluster status
  C. cat /etc/release
  D. cat /etc/cluster/release
  D. cat /etc/cluster/release

• Question 7:

  Which tasks are performed by the Sun Cluster 3.2 framework components?

  A. The CMM causes resource groups to fail over between cluster nodes.
  B. The RGM is used to start and stop the application on the cluster nodes.
  C. The CCR manages the cluster-wide agreement on the set of nodes booted into the cluster.
  D. If the RGM detects a critical problem with a node, it calls upon the cluster framework to forcibly shut down (panic) the node.
  B. The RGM is used to start and stop the application on the cluster nodes.

• Question 8:

  The cluster administrator is using ZFS to manage the shared storage for the cluster. You want to create a pool called "mypool". What is the command used to create a ZFS pool, and to verify that the pool has been created?

  A. 1) zcreate mypool c2t0d0s0 2) zstat
