Which task, or tasks, should be completed next? A cluster administrator wants to be sure that specific resource group will failover to the node with the most available processor resources. Which configuration supports the requirement? An administrator unintentionally changed the name of an online resource group on one node of a 2-node cluster. The cluster has not been synchronized since the change was made. How can the cluster configuration revert to the previous configuration without affecting the online resource group? Which action can an administrator do when the cluster has mixed versions within a rolling migration? While creating a new file collection named "custom" an administrator gets an "invalid name" error. What is the most likely reason for this error? When using PowerHA 7, a shared volume group (VG) must be configured as____________. An administrator created a 2-node PowerHA cluster. Each node is in a separate location, and each location has its own network. After starting the cluster, the network interfaces did not come up. Which action will correct this problem? Which command will show a summary of application servers in the cluster? After migrating to PowerHA 7 and restarting the cluster for the first time, the following error is reported: Starting Cluster Services on node: Jessica This may take a few minutes. Please wait... Jessica: cl_rshhad exit code = 13, see cspoc.log and/or clcomd.log for more information What is the most common cause of this error? A 2-node cluster has three multi-node disk heartbeat (MNDHB) networks and data volume groups on separate disks. Application resource groups are online on Node1. What happens if Node1 loses access to two of the three MNDHB disks? In multi-node disk heartbeat configurations running PowerHA 6, what is the recommended minimum number of LUNS to be shared between the nodes? Company policy requires logical volumes to be mirrored across separate disks and controllers for resilience. An administrator needs to create a 2-node cluster with the existing partitions. LPAR and LPAR2. The cluster will host an application with data on a shared volume group. LPAR1 and LPAR2 are currently hosted on a single Power 770. Each partition is assigned two integrated SAS controllers, each of which has internal hard disk drives (HDDs) that are currently used for rootvg. Which group of actions will create a shared volume group that complies with company storage policy? In a PowerHA 6 environment, what is recommended to ensure I/O disk-write buffers are flushed and to reduce chance of deadman switch timeouts? After upgrading one node of a 2-node cluster to PowerHA 7, an administrator discovered that the wrong disk was chosen for the repository disk. What must be modified on both nodes to correct this error without starting over from the beginning? What are the two types of application monitors that can be created? What are the two types of application monitors that can be created? If an application stop script fails during selective failover process, which action will recover the production service as soon as possible? An administrator notices that PowerHA has moved a resource group from one node to another. He looks on the vacated node, but doesn't see any problems reported in the application controller or application monitor logs. Why are the logs missing the pertinent information? A PowerHA 7 cluster is running on two fully virtualized LPARs. An administrator simulates a network failure on the cluster by running the "ifconfig enX down" command on all network interfaces on one node. The resource group moved, and clstat shows the cluster as stable on both nodes. What prevented the resource group from being active on both nodes? What cluster service settings can be defined in SMIT on one node of a cluster and automatically updated on all other nodes? An administrator wants to shut down a node which has a resource group from the HMC. Which shutdown option results in a node shutdown without failover? Complete the following statement: With a cluster using EtherChannel backup for high availability of network interfaces, the netmon.cf file setting is not needed for local network failure detection if EtherChannel backup has________: The addition of a service IP address to a resource group fails to pass verification and synchronization. What is the most likely reason? An administrator tries to replace a hot-plug Ethernet adapter using the C-CPOC > Communication Interfaces SMIT menu. When prompted, the administrator selects the incorrect adapter and does not wish to continue. When prompted to confirm adapter replacement, he selects "no". What is the first action that the administrator must take to restore cluster to the pre-maintenance condition? Which fileset must be installed to enable message authentication and encryption? An administrator wants to run the cluster test tool automated procedure. Part of this will perform a test to kill the dstrmgrES subsystem on a node, causing that node to halt. How can the administrator avoid manual intervention to restart the node? An administrator adds a new network interface to each node in a 2-node PowerHA 7 cluster, and sets the IP addresses. When is the new network interface used for heartbeating? A company is determining how they can use DLPAR operations within PowerHAto maximize the usage of their system. Which DLPAR attribute can be controlled through PowerHA? After upgrading one node of a 2-node cluster to PowerHA 7, an administrator discovered that the wrong disk was chosen for the repository disk. What must be modified on both nodes to correct this error without starting over from the beginning? While creating a new file collection named "custom" an administrator gets an "invalid name" error. What is the most likely reason for this error? Which utility can be used while a rolling migration is in progress? To provide a secure cluster environment, an administrator will use VPN tunnels for communication between the nodes in a cluster. What must be defined on the nodes for communication across the VPN tunnel? An administrator wants to configure a new3-node PowerHA 7 cluster for 3 instances of an application. Each node will host an instance under normal production mode. The administrator wants a node failover to be based on which cluster node has the most free real memory available. Which standard or user-defined dynamic node priority (DNP) attribute can be used to accomplish this? An administrator has configured a 2-node PowerHA 6 cluster, Nodel and Node2, with no non-IP networks. Sometime after configuring the cluster, the administrator noticed that Node2 appeared to have been shut down. After restarting Node2 the administrator analyzed the cluster log files in an attempt to determine the cause of the problem. The clstrmgr.debug log file contained the following information: Based on the above information, which of the following could explain why Node2 was shut down? An administrator unintentionally changed the name of an online resource group on one node of a 2-node cluster. The cluster has not been synchronized since the change was made. How can the cluster configuration revert to the previous configuration without affecting the online resource group? Which application dependency can cause problems if the application is installed on a shared disk? Complete the following statement: When planning to create PowerHA 7 nodes on Virtual I/O client partitions ________. An administrator plans to migrate a PowerHA 6 cluster with AIX 7 nodes to PowerHA 7. Which migration method should be used to minimize downtime? Which tasks will create and vary on a new volume group for an existing resource group in a 2- node cluster? When using PowerHA 7, a shared volume group (VG) must be configured as___________. When implementing PowerHA in a cross site LVM configuration, which logical volume option is required? Which operation can be done by DARE? Which command will show a summary of application servers in the cluster? A PowerHA 6 cluster has missed too many heartbeats during a large disk write operation, and has triggered the deadman switch. Which tunable can help ensure that HA Cluster Manager continues to run? The service IPs VLAN is the only routable network in a 2-node HA cluster with multiple network interfaces. What must done to enable administrative tasks to be performed remotely on the cluster nodes? What type of IP address configuration is required to enable Cluster Aware AIX (CAA) monitoring features? An administrator finds that a colleague has increased the size of a file system in an Enhanced Concurrent Volume Group using base AIX commands. How can the administrator make the cluster configuration consistent again? Failure to plan for which element will have a negative impact on PowerHA cluster availability, when using virtual I/O resources on the cluster nodes?
