What is used to shut down Veritas Cluster Server (VCS) on all nodes for patch installation without affecting the availability of the applications being managed by VCS?

A. hastop -all -failover

The cluster is in ADMIN_WAIT on startup. You restore the main.cf from a backup copy and verify it. What do you use next?

A. hastart -force

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.

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.

Given the partial main.cf definition:

group GroupA (

SystemList = { SystemA = 0, SystemB = 1, SystemC = 2, SystemD = 4 }

AutoStartList = { SystemA, SystemD }

OnlineRetryLimit = 3

OnlineRetryInterval = 120)

GroupA is online on SystemA.

All other systems are up and available.

Where will GroupA fail over to when SystemA faults?

A. SystemA

B. SystemB

C. SystemC

D. SystemD

An administrator needs to manually add a new resource type to a running cluster.

What should the administrator do after installing the agent software on each Veritas Cluster Server (VCS) node?

A. Generate the appropriate hatype commands with hacf -addtype

B. Use the hatype command to add the new resource type

C. Stop and restart VCS so that the new resource type is recognized as valid

D. Use the hares command to add the new resource type to the cluster

A failover service group uses the Process agent to start and stop an application and to monitor a list of processes. After bringing the group to an ONLINE state on a cluster system, you kill the monitored processes. The Enabled and Critical attributes of the resource are both set to a value of 1. The RestartLimit attribute for the resource is still set to the default value. Which action will VCS take?

A. Increment the TotalFault attribute

B. Initiate service group failover

C. Automatically restart the application

D. Take the service group offline without failover

If the hostname is changed in the sysname file, which three additional files must be modified? (Select three.)

A. llthosts

B. gabtab

C. llttab

D. main.cf

E. types.cf

An administrator is verifying the prerequisites of an application to ensure it can be placed under Symantec Cluster Server control.

Which two prerequisites must be met to accomplish this goal? (Select two.)

A. The operating system automatically starts the application.

B. The application is available to all nodes.

C. The shutdown process should be graceful performing cleanup operations.

D. The hardware administrative IP addresses are configured by Cluster Server on all nodes.

E. The shared storage is managed by Symantec Volume Manager.

Which two should be considered when manually taking a service group offline with service group dependencies? (Select two.)

A. For all soft dependencies, the child group can go offline regardless of the state of the parent group.

B. With firm dependencies, if the parent group is online, the child group offline is rejected.

C. For the online local hard dependency, if the parent group is online, the child group online is rejected.

D. The parent group offline is rejected only when the child group is online.

E. For hard dependencies, if the parent group goes offline, the child is taken offline automatically.
