VCS-256 Online Practice Questions and Answers

The administrator of a four-node Veritas cluster has configured notifications as highly available for all notification methods. How many notification manager resources are running when all nodes are considered?

A. only one

B. one for each ServiceGroup

C. one for each node

D. two resources (one for SMTP, one for SNMP)

Which two standard Veritas Cluster Server resource types can determine if an application is taken offline unexpectedly outside the cluster's control? (Select two.)

A. Process

B. FileOnOnly

C. CoordPoint

D. Application

E. Phantom

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

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

Which two requirements must be meet to allow an administrator to configure LLT heartbeats over UDP? (Select two.)

A. the LLT private links must be on the same subnet

B. each NIC must have an IP address configured before configuring LLT

C. the maximum transmission unit (MTU) must be set to the lowest value supported by the NICs

D. each link must have a unique UDP port

E. broadcast must be enabled for the heartbeat subnet

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.

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.

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.

C. The service group is evacuated to another system and HAD shuts down gracefully.

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

An administrator is creating a global service group. The requirement is to automatically fail over this service group to the remote cluster if the service group is faulted on all nodes in the local cluster, but only if the local cluster is still exchanging heartbeats with the remote cluster.

What is the appropriate value for the ClusterFailOverPolicy attribute in this scenario?

A. ClusterFailOverPolicy = Auto

B. ClusterFailOverPolicy = Connected

C. ClusterFailOverPolicy = Attached

D. ClusterFailOverPolicy = Online

Which service group dependency type supports two applications being online on any system in the cluster?

A. parallel

B. global

C. local

D. remote

Refer to the exhibit.

How many servers are seeded in the GAB port membership?

GAB status and membership notation

A. the GAB port membership has two nodes: 01 and 12

B. the GAB port membership has three nodes: 0,1, and 12

C. the GAB port membership has two nodes: 0 and 1

D. the GAB port membership has four nodes: 0,1,21, and 22

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

A. by restarting HAD, fencing, and GAB

B. by rebooting all the cluster nodes

C. by running the vxfenclearpre command

D. by restarting fencing

Which agent is used to automatically refresh fencing keys if they are missing on fencing servers or disks?

A. Fencing agent

B. Phantom agent

C. CoordPoint agent

D. Notifier agent

An administrator wants to make a new application highly available.

Which two capabilities must the application have to be managed be Veritas Cluster Server? (Select two.)

A. the ability to monitor each instance of the application independently.

B. the ability to be installed on shared storage

C. the ability to determine if the application is running

D. the ability to notify the administrator of the application's state

E. the ability to disconnect users from the application

What does the AdaptiveHA feature of Veritas Cluster Server (VCS) provide?

A. It uses the Priority attribute of service groups to take lower priority service groups offline when a higher priority service group fails over to the system.

B. It selects the biggest available target system to fail over an application when the service group attribute FailOverPolicy is set to BiggestAvailable.

C. It switches a service group with FailOverPolicy set to BiggestAvailable to less loaded systems in the cluster when the local system becomes overloaded.

D. It provides increased availability to the applications on the single node VCS cluster in virtual environments for planned maintenance events.

What is the purpose of the Statistics cluster attribute?

A. to collect metering data for supporting AdaptiveHA

B. to provide performance measurements to VIOM

C. to calculate availability and downtime levels

D. to calculate system and network resource usage
