Due to recent changes in infrastructure， a four-node cluster has been split into two locations， but is still listed as a single site in HACMP. The location split has proceeded smoothly， the only exception being the serial heartbeats. There are constant errors causing the serial network to go up and down. What is the best solution to resolve this issue？（）
Install the dialback failsafe optional filesets.
Change the speed parameter in smitty tty to be 38400，8，N，1.
Install additional rsct filesets required for non null modem connections.
Change the parameters in the Network Module to stop RSCT from changing the speed of the line.

On an existing two-node cluster， the system is configured with RAID5 SSA as the shared disk. When adding a new node to the cluster， what must be taken into consideration？（）
Nothing，SSA can support a maximum of 8 initiators per loop.
The RAID5 implementation on SSA will only support two initiators per loop.
SSA can only support four initiators per lop when using the fat write option.
The RAID implementation can be used with three initiators only if the fast write cache option is used on all adapters.

Company.com is adding HACMP to an existing pair of nodes. One node is using EtherChannel with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node. What other considerations need to be addressed in a HACMP environment？（）
Al interfaces used for HACMP heartbeats must be identical. Differences in the interfaces will cause heartbeat failure.
The network interfaces should all be configured with the same frame type. The use of regular Ethernet frames is mandatory.
Network interfaces for HACMP must be all the same，Ethernet or 802.3. It does not matter which，as long as they are all the same.
HACMP can use any network interface supported by AIX. The options on the various interfaces are masked by the Ethernet switch and do not affect HACMP.

Company.com recently updated the programs used in an HACMP pre-event. The procedure Involved coping the new code over the old code in the appropriate directory on one of the nodes as indicated by the HACMP event entry. The cluster was synchronized. During a fallover test， the backup system did not behave as expected. What is the most likely problem？（）
The new pre-event program was node locked to a hostname
The new pre-event program was not made executable on al nodes.
The new pre-event program was not compatible with the backup machine.
The new pre-event program was not propagated to all the nodes in the cluster.

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？（）
HACMP can resequence the order to the starting of the various resource group elements by utilizing Dynamic Node Priority.
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.
HACMP can delay making the network label available until after the filesystem checks have completed with the filesystem mounted before IP is configured.
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.

A node in a three-node cluster was started， ad it acquired the following three cascading resourcegroups： ’rg1’， ’rg12’， and ’rg3’. The cluster design is to have ’rg1’ normally Node ’A’， ’rg2’ normally on Node ’B’， and rg3’ normally on Node ’C’. How can the administrator reposition the resource groups and correct the problem？（）
Change the cluster resource group definitions from cascading to rotating，synchronize the cluster，and restart HACMP
Edit the /urs/es/sbin/utilities/clhosts file to reflect he desired node-to-resource group relationships and restart HACMP
Use the clRGMove utility move rg2 o Node ’B’ and rg3 to Node ’C’，then start the cluster manager on Nodes ’B’ and ’C’ with the clstart utility
Disable Inactive Node Takeover，check the node priority list in the resource groups definitions，synchronize the cluster，and start HACMP on Nodes ’B’ and ’C’

Company.com has a two-node HACMP cluster with a single cascading resource group. Node ’A’ is the normal production node， and Node ’B’ is the standby node. One of the first steps in the HACMP test plan is to start the cluster and to verify that al elements for the resource group have been acquired. The administrator who is conducting the HACMP test starts the HACMP daemons on Node ’B’ with the ’smitty clstart" command. The administrator notices that Node ’B’ acquires the elements of the resource group， including a service IP labels，a shared volume group， and an application server that has been started. The expectation was that Node ’B’ would enter the cluster in a standby status， rather than acquiring production resources. What should the administrator do to correct this problem？（）
Change the cluster to a rotating design.
Change the Cascading without Fallback flag to true.
Change the Inactive Takeover field to false in the cluster configuration.
Nothing should be done. This is the default behavior for cascading resource groups，and node ’A’ should have been started first.

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？（）
Execute lssrc -g cluster stop on Node ’A’
Execute cat /etc//motd >/dev/kmem on Node ’A’
Execute /usr/es/sbin/cluster/utilities/sclstop -gr on Node ’A’
Find the pid of cluster manager daemon on Node ’A’ and issue a kill-9 against the pid
