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

单项选择题Following an unsuccessful cluster fallover test， it is determined that the nfsrg1 resource group was the problem causing the cluster to run the config_too_long evetn. The nfsrg1 resource group contains 10 nfs filesystems that are cross-mounted to the other cluster node. Without modify8ing the time until warning parameters，what can be done to enhance NFS fallover performance？（）

A. Increase the number of NFS daemons for increased performance.
B. Modify the nfsrg1 resource group to use local NFS cross-mounts.
C. Create a second resource group to manage half the NFS cross-mounts.
D. Create post events to handle the cross-mounts after fallover processing.

A. The dominate site will always assume the non-dominate site has failed and continue processing.
B. The dominate site initiates a call to the non-dominate site to verify if any of the nodes are functional.
C. The non-dominate site initiates a call to the dominate site to verify if any of the nodes are functional.
D. The nodes are completely independent and can call each other if they detect a total failure of the ZGeo_Primary network.
