单项选择题When an emulated error notification method is complete， an administrator can view the error log  By typing the errpt command to be sure the emulation took place.  To verify that the error log entry is the result of the emulated event，the log entry resource name is set to EMULATOR，or which of the following？（）

A. A user defined Resource Name
B. A cluster defined Resource Name
C. An error daemon specific Resource Name
D. A Resource Name generated by Automatic Error Notification

单项选择题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.

单项选择题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’.

单项选择题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？（）

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
