Change the cluster to a rotating design.
Change the Cascading without Fallback flag to true.

第1题:
The IP subsystem fallover behavior of a two-node cluster is being testing in a large client organization. One of the tests is to simulate a network_down event and verify that HACMP movesthe single resource group to the standby node. What is the best way to simulate a network down condition?()
第2题:
A new administrator is performing fallover testing on a two-node cluster and is concerned that the cascading resource group belonging to Node ’A’ did not reintegrate properly after the cluster was restarted on Node ’A’. A stable cluster is reported by clstat,and clRGinfo reports the resource group online on Node ’B’. What type of configuration would cause this type of behavior?()
第3题:
An enterprise has three nodes: -Node ’A’ is a production database, -Node ’B’ is a production Application server, and -Node ’C’ is a test and development node. Node ’C’ is used by six programmers to develop and the production application as business critical and would like to make it highly available with HACMP. Application development and testing is not business critical. Which of the following describes the best solution?()
第4题:
An enterprise has two nodes: -Node ’A’ runs a large relational database and ha six CPUs and 32GB of memory. -Node ’B’ is an application server with three CPU’s and 16GB of memory. During peak production periods, the CPU load for Node ’A’ is normally between 30% and 40%. For Node ’B’, the CPU load is 10% to 20% during peak production periods. Which of the following describes the best solution for an HACMP cluster?()
第5题:
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?()

第7题:
There is not an adequate solution because HACMP should not be configured in this environment without a dedicated standby node.
Nodes ’A’ and ’B’ should be configured in a cluster with mutual fallover of two cascading resource groups to provide both nodes will deliver acceptable response time with both resource groups.
Nodes ’A’ and ’C’ should be configured in one cluster, and Nodes ’B’ and ’C’ in another cluster to prevent both the database and application server from falling over to Node ’C’ at the same time.
Nodes ’A’, ’B’, and ’C’ should be configured in a cluster with Node ’C’ the hot standby for both the database and application server resource groups. Workload Manager (WLM) must be configured on database and application developers from over utilizing the CPU resources.

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.
第9题:
Use the clstat command.
Use the cIRGinfor command.
Tail the /etc/hacmp.out file and wait for node_up_complete to finish successfully.
Tail the /usr/es/adm/cluster.log file and wait for node_up_complete to finish successfully.
第10题:
Turn off the IP core switch connecting the two nodes.
Issue the command stopsrc -g inetd on the node that has the resource group.
Issue the command sh /etc/rc.tcpclean on the node that has the resource group.
Simultaneously unplug all network cables from the node that has the resource group.
第11题:
Use thee cascading resource groups where ’rg1’ and ’rg2’ fallover to Node ’B’ and ’rg3’ falls over to Node ’C’
Use Dynamic Node Priority resource groups with a priority chain consisting of Node ’A’ then Node ’B’ then Node ’C’
Use three rotating resource groups with ’rg1’ and ’rg2’ falling over to node ’B’ and ’rg3’ falling over to Node ’C’
Upgrade Nodes ’B’ and ’C’ to be equal to Node ’A in CPU and memory resources to enable the cluster to synchronize three resource groups
第12题:
rg1 is configured with a delayed fallback timer
Settling time policy has not been configured for rg1
Node1 does not have sufficient resources to support rg1
Node2 is the first in the ’Default Node Priority’ list for resource group rg1
第13题:
A three-node cluster experienced a node failure. The resource groups were acquired as cexpected. The node has been repaired,and HACMP has been restarted. How does the operator determine that the node has successfully re-integrated into the cluster?()
第14题:
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?()
第15题:
The first step documented in Company.com’s HACMP test plan is to start the cluster manager on the normal service node and verify that HACMP daemons have started with the ’lssrc -g cluster" command. What daemons MUST show as active in the ’lssrc -g cluster" command to have an operational cluster?()
第16题:
An HACMP setting timer may used to allow:()
第17题:
The setting or fallback of a cluster custom resource group
The cluster time to stabilize before starting a custom resource group
A priority node time to acquire custom resource group at cluster start
A fallover node time to process custom resource states to be monitored
第18题:
The resource group DNP has been configured.
The resource group option CWOF has been enabled.
The resource group option Inactive Takeover is set.
A resource group fallback timer has been configured.
第19题:
The concurrent application must control the web interface through application monitoring.
A second resource group will be required to move the web application and IP label to a new node during a node failure.
The concurrent resource group can support multiple IP labels through IP aliasing so all IP labels are defined in the concurrent resource group.
The dynamic node priority facility in HACMP will relocate the web application and the IP label,if it is correctly defined in the application start and stop script.

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
