While performing a site survey to document the existing environment before implementing a new HACMP cluster， it was discovered that a port filtering firewall was being used to protect the production system. The plan is to continue using the firewall and add a second firewall to avoid a single point of failure. Each node in the two-node cluster will have all of its network adapters connected to the firewalls， and all connections to the nodes will pass through these firewalls. What must be considered about HACMP in a firewall environment？（） A、 Firewalls are not supported in a HACMP environment.B、 HACMP uses only TCP/IP so firewalls are not relevant.C、 Specific ports must be open for HACMP communications.D、 Dynamic routing must be used to properly route packets in a firewall-protected environment.
While installing the equipment for a new two-node cluster， it is discovered that the disk subsystem Rack has one connection to the power mains. The explanation given was that the disks are to be mirrored between the two disk drawers in the rack and that a failure in either of the disk drawers would simply result in half of the disk being lost. What can be done to avoid a single point of failure？（） A、 Customize HACMP to overcome quorum issues.B、 Add a second PDU to separate the power connections.C、 Use RAID5 when implementing two IO racks in a HACMP environment.D、 Add another shared disk to each volume group to avoid quorum issues during fallover.
A cluster administrator is performing fallover testing during a scheduled system outage. Node ’A’ Was forced down and eventually rebooted. When Node ’A’ reintegrates into the cluster， the resource group state is offline. No errors are found in reviewing the hacmp.out file. What could have been done to ensure the resource group was acquired when cluster processing was restarted on Node ’A’？（）A、 Nothing，HACMP does not require them automatically.B、 Force the remaining nodes down，then reintegrate them all.C、 Select reacquire resources after forced down on start menu.D、 Create a setting timer to bring the resource group online.
Company.com has a three-node cluster with six resource groups. There are two resource groups for each node. A new hardware component will be added to one of the nodes. The customer wants to move the resource groups to other nodes，but not necessarily in the normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient normal fallover order. Also，the resource groups must be moved at night when there is no one in the computer center. What can be done so that the resource group is moved at the most convenient time for the customer？（） A、 Create a custom resource group with a custom fallback timer to cause the system shutdown at he appropriate time.B、 Set the system to stop with "shutdown" command at the appropriate time and allow HACMP to relocate the resources.C、 Use a script that calls the cIRGmove command and place it in the cron or a queue to execute at the appropriate time.D、 Change the existing resource groups to a custom type and add a timer to perform a "shutdown -h" command at the appropriate time.
The user base of a three-node cluster has increased. In order to add clustered users to all nodes， which of the following steps should be performed？（） A、 On one of the nodes，add the users via C-SPOC ’Add a User to the Cluster’smit menu.B、 Use C-SPOC to synchronize the password files between cluster nodes.C、 On all of the nodes，add the users to the /etc/passwd and system security files，and then synchronize the cluster.D、 On one of the nodes，add the users to the /tec/passwd and system security files，add home directories，and use cron to automate the movement of system security files between nodes.
Company.com has a resource group that contains a database that is accessed by a web client based on another system. The communication to the database is TCP/IP. Occasionally after a failure， the end users get unusual error messages that indicate the database server is not available. It has been determined that the web server is trying to access the database server’s information before it has completed file system recovery after a failure. How can HACMP affect this problem？（） A、 HACMP can resequence the order to the starting of the various resource group elements by utilizing Dynamic Node Priority.B、 The order of dependency can be controlled though the HACMP resource group configuration if the web server was made to be part of the HACMP cluster.C、 HACMP can delay making the network label available until after the filesystem checks have completed with the "filesystem mounted before IP is configured".D、 The IP service label can be in a second resource group allowing the sequential processing of resource groups to control when the IP service label is made available.
Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server.
