VCS-256 Online Practice Questions and Answers

Due to a high security risk, a mandatory shutdown of Ethernet switches is scheduled in a data center where the switches are used for two private heartbeat links on a local cluster. A low-priority heartbeat link, which has been configured over a public interface, is unaffected by the shutdown. I/O fencing is disabled.

Which cluster behavior is expected when the private switches are both shut down for the upgrade?

A. All nodes in the cluster panic.

B. The cluster remains online, but the service groups go offline.

C. Private cluster communications are rerouted over the public network.

D. The service groups go into ADMIN-WAIT state.

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?

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.

Which requirement must be met to allow two separate Veritas InfoScale clusters to share a common private heartbeat network switch?

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

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

C. The cluster IDs must be unique across the clusters.

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

What is the minimum number of coordination point servers needed to protect data from corruption in a production seven-node cluster server environment that requires I/O fencing?

A. 1

B. 2

C. 3

D. 4

The hastatus command shows a service group in the AutoDisabled state, and Veritas Cluster Server is unsuccessful in bringing the service group online automatically. Which command can the administrator use to reset the AutoDisabled attribute?

A. hagrp –autoenable -sys

B. hagrp –flush -sys

C. hagrp –online -sys

D. hagrp –modify AutoDisabled 0

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.

Which Veritas Cluster Server components integrate into a VMware environment?

A. vSphereDisk agent and Application HA

B. Veritas High Availability Plug-In and VMwareDisks agent

C. Dynamic Multi-Pathing and Veritas InfoScale Operations Manager

D. Cluster Management Console and Enterprise Administrator

What is the purpose of the AutoClearLimit attribute?

A. It defines the number of attempts to clear the Faulted state of a resource on all nodes.

B. It defines the number of attempts to clear the Faulted state of a service group on all nodes.

C. It defines the number of attempts to clear the AutoDisabled state of a service group on a node.

D. It defines the number of attempts to clear Faulted state of a resource on a single node.

An administrator manually edits the Veritas Cluster Server configuration file while a cluster is stopped. When the cluster is restarted, all the changes made are missing. Why are the changes made to the configuration file missing?

A. The cluster was started first on the node where the changes were made.

B. The haconf –save command needs to be run after making the manual changes.

C. The cluster was started first on a node other than the one where the changes were made.

D. The haconf –dump command needs to be run prior to starting the cluster.

How is the Authority attribute of a global service group used?

A. to authorize the users who have administrative privileges over the global service group

B. to authorize the cluster on which all administrative actions should be performed for the global service group

C. to give authority for automated failover of the global service group across remote clusters

D. to specify the right to attempt bringing the global service group online in the cluster
