Question 1

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?

Options:

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

Question 2

What are two resource types that Proxy resources can reference? (Select two.)

Options:

A.

NIC

B.

IP

C.

Mount

D.

DNS

E.

ElifNone

Question 3

How can an administrator remove existing keys from the coordinator disks?

Options:

A.

by restarting HAD, fencing, and GAB

B.

by rebooting all the cluster nodes

C.

by running the vxfenclearpre command

D.

by restarting fencing

Question 4

Which category of resources is considered by Veritas Cloud Server when determining whether a service group is online?

Options:

A.

On-Off

B.

Failover

C.

On-Only

D.

Persistent

Question 5

Refer to the exhibit.

In a three node cluster, the orasg service group is online on one of the systems. The service group has the resources and resource dependencies shown in the exhibit. All resources are critical resources and the following service group attributes have been configured:

  • ManageFaults = ALL
  • FaultPropagation = 0
  • AutoFailOver = 1

What is the expected behavior when the mnt2 resource fails?

Options:

A.

The service group fails over to one of the other systems in the cluster.

B.

The service group is taken offline and remains offline in the cluster.

C.

The mnt2 resource is taken offline, all other resources remain online.

D.

The mnt2 resource and all its parent resources are taken offline, the rest remain online.

Question 6

An administrator wants to install InfoScale Availability.

Which hardware requirement ensures successful installation of Veritas Cluster Server?

Options:

A.

at least one SCSI or Fibre Channel Host Bus Adapter per system

B.

at least one dedicated Ethernet interface per system for private interconnects

C.

all shared storage disks support SCSI-3 Persistent Reservations

D.

gigabit Ethernet using enterprise-class switches for private interconnects

Question 7

An administrator is configuring a websg service group and a dbsg service group. The administrator needs to configure Veritas Cluster Server so websg will only come online if dbsg is online somewhere in the cluster.

If dbsg faults, websg should stay online. If dbsg is unable to fail over, the websg should stay online.

Which type of service group dependency does this require?

Options:

A.

online global soft

B.

online global firm

C.

online local soft

D.

online remote soft

Question 8

An installed cluster has been licensed with the keyless licensing option. The administrator has yet to configure the cluster to be managed by Veritas InfoScale Operations Manager (VIOM). What will happen when 60 days have passed since installation?

Options:

A.

The cluster will shut down.

B.

The cluster will log messages related to licensing.

C.

The cluster will disallow administrative changes until licensed.

D.

The cluster will cease to respond if a resource faults.

Question 9

Which log can an administrator review to determine why a resource failed to come online?

Options:

A.

/etc/VRTSvcs/conf/config/main_A.log

B.

/var/VRTSvcs/log/messages_A.log

C.

/var/VRTSvcs/log/resources_A.log

D.

/var/VRTSvcs/log/engine_A.log

Question 10

As part of the consolidation efforts in a data center, the administrator decides to merge two two-node Veritas Cluster Server (VCS) clusters into a four-node VCS cluster. The source and target clusters are on the same networks for LLT communication. The administrator performs the following tasks as preparation for the merge while both clusters are still running:

  • modifies /etc/llttab files on the source cluster systems so the cluster ID is changed to the cluster ID of the target cluster
  • modifies /etc/llthosts files on all systems to include the four nodes
  • modifies /etc/gabtab files on all systems to require the four systems to seed
  • ensures the source cluster systems can see the fencing disks used by the target cluster
  • copies the fencing configuration files from the target cluster systems to the source cluster systems
  • adds the source cluster systems to the target cluster configuration using the hasys –add command

After the preparation is complete, the administrator stops the source cluster leaving the applications running, then stops the whole communication stack and restarts it in the correct order. When the administrator attempts to start the cluster again on the source cluster systems, they fail to join the four-node cluster.

Which preparation step that the administrator failed to perform is preventing the source cluster systems from joining the four-node cluster?

Options:

A.

The cluster needs to be manually seeded using gabconfig -x on the source cluster systems.

B.

The target main.cf file needs to be copied to the source cluster systems.

C.

The service group configuration of the source cluster needs to be applied to the target cluster.

D.

The cluster UUID from the target cluster needs to be copied to the source cluster.

Question 11

Which requirement must an administrator meet prior to implementing an InfoScale Availability cluster that includes both physical and virtual machines?

Options:

A.

ensure all systems in the cluster have access to virtualized storage devices

B.

ensure shared storage supports SCSI3 persistent reservations

C.

ensure shared storage supports multi-pathing

D.

ensure the systems in the SystemList for a service group have access to the same shared storage devices

Question 12

Which action is performed by the CoordPoint agent?

Options:

A.

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

B.

It monitors only the coordination point server.

C.

It monitors cluster node registrations with coordination point servers and SCSI-3 disks.

D.

It removes offline cluster nodes from the coordination point servers.
