Question # 4

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?

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 # 5

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

Question # 6

Which two capabilities must an application have in order to be made highly available using 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 state

E.

The ability to disconnect users from the application

Question # 7

An administrator wants to deploy a complex cluster configuration that will include over six nodes, I/O fencing, and multiple private cluster interconnections.

Which method will help the administrator to implement rapid cluster deployment?

A.

prepare a custom main.cf file using the sample template files and copy the file to all cluster nodes

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 (VIOM) and push it out to the new cluster

D.

prepare a custom response file to build the new cluster configuration using /opt/VBTS/inscall/installer

Question # 8

Which behavior should an administrator expect when performing 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 during the update process, but the service groups are offline.

Question # 9

An administrator is evaluating the suitability of an application to be clustered using Veritas InfoScale Availability.

Which condition prevents the application from being made highly available?

A.

The application requires the use of solid state drives for performance.

B.

The application requires multiple systems accessing shared data simultaneously.

C.

The application has a dependency on the host name of the system on which it is running.

D.

After a crash, the automated clean-up takes at least one minute before the application can be restarted.

Question # 10

What happens when a split-brain occurs and I/O fencing is disabled?

A.

All nodes are placed in jeopardy membership.

B.

All service groups are autodisabled.

C.

Nodes on each side of the split try to bring service groups online.

D.

All nodes execute a stop operation.
