第1题：

While an electrician was adding additional circuits for the Data Center， the system running the Database inadvertently powered down. The fallover of the service IP labels and volume groups to the hot standby node completed as expected； however， the database did not start. The database log file indicated that the database was already started.  What is the most likely cause of this problem？（）

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.

第4题：

A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’.  What statement most accurately describes this situation？（）   

• A、 EtherChannel is needed to automatically switch the service IP address back to ’ent0’.
• B、 This is the default behavior for a network interface failure with this configuration.
• C、 Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.
• D、 The Inactive Network Takeover option should be set to "true" to forece the service address back to ’ent0’.

第5题：

During Company.com planning session， the discussion focuses on how the IP connections are  Managed after a cluster node failure. This is critical for the business since their production application is a Lotus Domino solution requiring multiple IP addresses and recovery time is critical.  What type of IPAT implementation would best address these requirements？（）  

• A、 IPAT via IP aliasing
• B、 IPAT via IP replacement
• C、 IPAT via IP aliasing using HWAT
• D、 IPAT via IP replacement using HWAT

第6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？（）   

• A、 Change the cluster to a rotating design.
• B、 Change the Cascading without Fallback flag to true.
• C、 Change the Inactive Takeover field to false in the cluster configuration.
• D、 Nothing should be done. This is the default behavior for cascading resource groups，and node ’A’ should have been started first.
