GAB can be configured to automatically seed the cluster through I/O fencing, even when some cluster nodes are unavailable. In which file does the autoseed_gab_timeout parameter need to be configured to enable this feature?
A. gabtab
B. main.cf
C. vxfenmode
D. vxfentab
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.
Consider the following configuration:
group websg (
SystemList = { sym1 = 1, sym2 = 2 }
AutoStartList = { sym1 }
Frozen = 1
)
While websg is online, all of the systems in the cluster are rebooted simultaneously. All of the systems finish booting and successfully join the cluster.
What will happen to the websg service group?
A. It will unfreeze on reboot and start on sym1.
B. It will remain offline on all systems.
C. It will resume its state before the reboot.
D. It will start on sym1 in a frozen state.
An administrator is configuring another application service in high availability. The application's logical IP address will rely on the same NIC used by the ClusterService service group. Data will be stored on raw devices. Which types of resources should the administrator consider to configure in the service group?
A. Application, File System, Volume, Disk Group, IP, NIC
B. Application, Volume, Disk Group, IP, Proxy
C. Application, File System, Volume, Disk Group, IP, Proxy
D. Application, Volume, Disk Group, IP, Phantom
What are two resource types that Proxy resources can reference? (Select two.)
A. NIC
B. IP
C. Quorum
D. DNS
E. ElifNone
What is a limitation of using the web-based installer?
A. The server where the web browser is launched must be the same operating system as the target system.
B. The server where the installation is launched must be the same operating system as the target system.
C. The Veritas XPortal Server process must be started on the target server.
D. The web-based installer can only be used to perform standard upgrades.
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
In the event that all heartbeats are lost on all interfaces, what should be implemented to reduce the likelihood of a split brain condition?
A. Configure AutoRestart for LLT
B. Configure and enable postonline_ipc trigger
C. Enable SCSI 2 disk reservation
D. Configure I/O Fencing
For which VCS feature is configuration optional during the install using installvcs?
A. I/O Fencing
B. Perl
C. Notification
D. Bundled Agents
