The administration staff of a large computer complex is resisting the installation of HACMP. There Are concerns about the difficulty of managing and administering an HACMP cluster without an "administration only" network. Adding adapters to create an administration network is not possible due to limitations on the number of open IO slots in the servers. What can be done to address this issue？（）
A. Create HACMP persistent IP labels for administration purposes.
B. Use HWAT to ensure the correct MAC address is available at all times.
C. Nothing can be done because RPAT is a characteristic of HACMP that cannot be changed.
D. Use IP aliasing within HACMP to allow the administrators constant access to the nodes.

During a planning session， Company.com expresses concern about the behavior of the nodes When HACMP is installed. Once department is reliant on an older piece of equipment that is critical to operations and must communicate to the database server. Previous network changes indicated that this piece of equipment does not support gratuitous ARP. How can HACMP best incorporate this restriction into the cluster design？（）
A. The administrator must use Hardware Address Take over with HACMP.
B. The clsmuxpd process and the contents of the /etc/cluster/ping_client_list can address the issue.
C. HACMP does not have any facility to be compatible with older devices that have limited capabilities.
D. HACMP can use either hardware address take over，or clinfo can update the arp cache of the clients when an adapter event occurs.

Following a successful migration，it is highly recommended that concurrent Volume Groups be Converted to enhanced concurrent capable Volume Groups. In order to follow this recommendation，what step must be completed first？（）
A. The Volume Groups must be changed with chvg -E vgname.
B. The Volume Groups must be a member of a resource group and must be varied on al nodes of the cluster.
C. The Volume Groups must be a member of a resource group and must be varied off all nodes of the cluster.
D. The Volume Grups cannot be changed to enhanced concurrent capable because they must be recreated with mkvg -C vgname.

While reviewing cluster logs， and administrator notice that an event， network_down rs232a， occurred on the previous day. After verifying the physical network connections and device states， what command can be used to verify the cluster state？（）
A. clstat
B. cllsif
C. clsnapshotinfo
D. clcheck_server

A Cluster Administrator is implementing a custom resource group for a new web application. The goal is to ensure the resource group is always active. Preference should be given to the priority node at startup time，but fallback to the priority node should be scheduled during a nonbusy time. Using custom resource group options， what combination best achieve the desired resource group behavior？（）
A. Online On All Available Nodes，using a setting timer
B. Online On Home Node Only，using a fallback timer
C. Online On Home Node Only，using both setting and fallback timers
D. Online On First Available Node，using both settling and fallback timers

When the clverify utility is run，verification checks use ODM data provided by the common communication infrastructure. This provides efficient access to configuration ODMs from the other nodes. The utility manages these files by storing the copies in various directories depending on the success or failure of the verification pass. By default，this directory is "/var/hacmp/clverify/current/nodename/ if the ’current’ directory still exists when clverify stops running，this indicates which of the following？（）
A. A successful completion of clverify
B. A problem with the clverify utility
C. All nodes agree on active configuration
D. Configuration differences between current and last successful clverify

Company.com performs cluster verification every Sunday night with a corn job. The systems administrator reviews the /var/hacmp/clverify/clverify.log on Monday morning and notice that cluster verification posted a message about inconsistent filesystem names in one of the shared volume groups. What should the administrator do？（）
A. Cause a fallover to occur on the resource group.
B. Export the volume groups and re-import them on all nodes.
C. Run an importvg -L command on all the nodes in the cluster.
D. Investiage recent changes to the shared volume group and use C-SPOC to correct inconsistencies.

During an HACMP migration，two nodes of a four-node cluster have been migrated. The existing hardware of the remaining two nodes do not meet the pre-requisites of the HACMP level that is being installed. Which of the following is the best method for resolving this issue？（）
A. Upgrade the unsupported hardware and continue with the migration.
B. Restore the two nodes that have been migrated with a cluster snapshot.
C. Restore the two nodes that have not been migrated with a cluster snapshot.
D. Synchronize the cluster to allow the nodes that didn’t migrate to join the cluster.

A step in the HACMP test plan is to gracefully stop the cluster on a node and to verify that the Shared resources fallover to the standby node. To prepare for this testing step， both nodes in the two-node cluster are in a stable state with the single resource group active on Node ’A’. Which of the following is the best way to execute this portion of the test plan？（）
A. Execute "lssrc -g cluster stop" on Node ’A’
B. Execute "cat /etc//motd >/dev/kmem" on Node ’A’
C. Execute "/usr/es/sbin/cluster/utilities/sclstop -gr" on Node ’A’
D. Find the pid of cluster manager daemon on Node ’A’ and issue a "kill-9" against the pid

An administrator is reviewing the /tmp/hacmp.out after an unsuccessful fallover and notice that the event stop_server PROD_DB failed. Besides manually intervening，what step must be performed to return the cluster to a stable state？（）
A. Recover From HACMP Script Failure.
B. Release Locks Set By Dynamic Reconfiguration.
C. Rerun HACMP cluster verification and synchronization.
D. Restore HACMP configuration Database From Active Configuration.
