• Question 43:

  A cluster administrator wants to deploy a complex cluster configuration that will include over six nodes, I/O fencing, and multiple private cluster interconnections. The administrator has a week to prepare before the actual cluster nodes become available for software installation.

  Which method will help the administrator to implement rapid cluster deployment?

  A. prepare a custom main.cf file using the sample template files

  B. generate a custom installation script using the Veritas Services and Operations Readiness Tools (SORT) website

  C. prepare a custom response file in Veritas InfoScale Operations Manager and push out to the new cluster

  D. prepare a custom response file to build the new cluster configuration

  Correct Answer: D

• Question 44:

  Refer to the exhibit.

  The exhibit shows an N-to-1 cluster configuration, in which nodes are connected to storage devices via dual-hosted SCSI cables.

  Why is this an inefficient configuration?

  

  A. Storage should be shared by more than two nodes, obtaining a N+1 cluster configuration.

  B. Clusters should have at most two nodes.

  C. NAS is preferred over SAN for shared storage.

  D. NFS is the preferred way to share storage within a cluster.

  Correct Answer: A

• Question 45:

  What happens when an administrator executes hastop-local on a system that has an online service group which is frozen persistently?

  A. HAD is killed on the system so the system state changes to faulted in the cluster.

  B. HAD shuts down gracefully but leaves the application running.

  D. The command is rejected and HAD continues to run.

  Correct Answer: A

• Question 46:

  Which action is performed by the CoordPoint agent?

  A. Is registers cluster nodes with coordination disks and coordination point servers.

• Question 47:

  Which behavior should an administrator expect when using the Veritas InfoScale Availability online upgrade process using the installer?

  A. The cluster remains online and the kernel processes are swapped during the upgrade process.

  B. The cluster is taken offline one node at a time during the package upgrade.

  C. The cluster is taken offline during the upgrade process, but the applications stay online.

  D. The cluster remains online until the next reboot and an alternative boot disk is used.

  Correct Answer: B

• Question 48:

  An administrator has a three-node cluster with low-priority heartbeat link and SCSI-3 I/0 fencing configured. Priority is given to node1, and each node is running a separate application. What will occur when all dedicated heartbeats fail at the same time?

  A. The cluster faults and the subcluster with node1 in it panics.

  B. The cluster moves all applications to node1.

  C. The cluster continues to run without impact to the application.

  D. The cluster faults and the subcluster with node1 in it remains online.

  Correct Answer: D

• Question 49:

  B. /opt/VRTSvca/bin/hagetcf

  C. /opt/VRTSvca/bin/nodedump
