A. VCS was started on the node where the changes were made.

B. VCS was started on the node without the changes being made.

C. VCS was started on the node with the lowest priority in the SystemList.

D. VCS was started on the node with the highest priority in the SystemList.

What is required in order to have two separate Veritas clusters share a common private heartbeat network switch?

A. GAB network IDs must be unique across the clusters.

B. All node IDs must be unique across the clusters.

C. Cluster IDs must be unique across the clusters.

D. All LLT node IDs must be unique across the clusters.

A parallel service group named net_sg is online on SystemA, SystemB, and SystemC in a threenode cluster. The service group contains a critical NIC resource and a non-critical Phantom resource. If the network device specified in the NIC attribute fails on SystemA, the net_sg service group state is _____.

A. Faulted on SystemA, online on SystemB and SystemC

B. Faulted on SystemA, SystemB, and SystemC

C. Offline on SystemA, online on SystemB and SystemC

D. Partially online on SystemA, online on SystemB and SystemC

The procedure for making changes to the Veritas Cluster Server (VCS) cluster communications involves stopping the components in the communications stack, modifying the configuration files, and restarting the stack.

In what order should the components be stopped?

A. LLT, GAB, I/O fencing

B. VCS, I/O fencing, GAB, LLT

C. VCS, I/O fencing, LLT, GAB

D. I/O fencing, VCS, GAB, LLT

What are two requirements for configuring disk-based I/O fencing on supported storage arrays? (Select two.)

A. Cluster File System Option enabled

B. Arrays with SCSI3-PR enabled

C. A minimum of two private heartbeat connections

D. LUNs visible within the vxdisk list output

E. LUNs validated with the hacf -verify command

VCS is to be installed in a secure environment where remote installation between systems is impossible. The VCS configuration parameters were captured in a file using the installation script on the first system. What can be used to read the contents of the configuration file when executing locally on the remaining systems?

A. -autoconfig

B. -configfile

C. -vcsconfig

D. -responsefile

Assume that the GroupA service group is online on SystemB.

Given the following configuration file:

group GroupA (

SystemList = { SystemA = 1, SystemB = 2 }

AutoStartList = { SystemA }

)

IP ip0 (

Device = nic0

Address = "10.10.10.10"

NetMask = "255.255.255.0"

)

NIC nic0 (

Device = nic0

NetworkType = ether

)

NIC nic1 (

Device = nic1

NetworkType = ether

)

ip0 requires nic0

What happens to the GroupA service group if the network cable connected to nic0 is unplugged on SystemB?

A. GroupA faults on SystemB and attempts to fail over to SystemA.

B. GroupA faults on SystemB and attempts to restart on SystemB.

C. IP traffic is rerouted to the nic1 interface.

D. The nic0 resource faults and GroupA stays partially online.

Before attempting to verify the operation of LLT, GAB, or the cluster, the following steps are taken:

Log in to any node in the cluster as superuser. Place the VCS command directory in your PATH variable: # export PATH=$PATH:/usr/sbin:/sbin:/opt/VRTS/bin:/opt/VRTSvcs/bin

Which command is invalid for configuration verification?

A. haconf -display

B. hastatus -summary

C. lltstat -nvv

D. gabconfig -a

An administrator is planning to configure a new application service in a Veritas cluster. In the case of an application failure, the company requires that the node with the fewest running service groups be selected as the failover target.

Which failover policy should the administrator implement to achieve this requirement?

A. Priority

B. RoundRobin

C. Quorum

D. Prerequisites

What must you do to upgrade an application in a service group under VCS control? (Choose two.)

A. Verify the application's agent supports the new version

B. Disable the application's resource type

C. Freeze the application's service group

D. Freeze the application's resource

E. Stop the application's agent on all systems
