IBM PowerHA SystemMirror V7.2 Implementation Practice Exam 2025: Latest Questions

During initial planning, an administrator must ensure the cluster can consistently identify each node and establish stable communication across networks. Which prerequisite is MOST important to validate before installing PowerHA SystemMirror?

A two-node PowerHA cluster uses IP address takeover for a customer-facing application. After a failover, clients must reconnect to the same address without changing their configuration. Which PowerHA feature provides this behavior?

An administrator is building an application resource group that must start filesystems before starting the application, and stop the application before unmounting filesystems. What is the BEST way to ensure correct start/stop ordering in PowerHA?

A planned maintenance requires stopping cluster services on a node without forcing a failover of resource groups currently running on that node. Which action most directly meets this requirement?

A cluster uses shared SAN LUNs. The team wants to prevent both nodes from accessing the same volume group at the same time after a split-brain condition. Which PowerHA/AIX mechanism directly addresses this risk?

An application must fail over automatically if the process becomes unresponsive, even though the node and network remain healthy. Which configuration is MOST appropriate?

A two-site design requires minimal data loss but also needs predictable failover behavior if WAN latency spikes. The application uses synchronous storage replication across sites. Which planning decision BEST aligns with these requirements?

After configuring a new resource group, a test fallover fails because the filesystem does not mount on the takeover node. The volume group appears varied on, but the mount point is missing. Which is the MOST likely root cause?

A cluster uses shared disks with persistent reservations. After an unexpected reboot of the primary node, the standby node cannot varyon the volume group during takeover and reports reservation conflicts. What is the BEST corrective action to restore automated takeover while maintaining disk fencing?

In a multi-node cluster with rotating fallover, an application occasionally starts twice on the same node after a rapid sequence of failures and recoveries. Logs show overlapping start events for the resource group. Which approach is MOST appropriate to prevent concurrent start actions and ensure serialized recovery?

An administrator wants to verify that the PowerHA cluster services are currently active on a node and that the node is recognized as part of the cluster. Which command is the most appropriate quick check?

A new cluster is being planned and the networking team can provide only one physical network per node. The architect wants to minimize single points of failure for the cluster communication path. Which design is the best practice in this constraint?

A resource group contains a service IP label and an application start script. During a planned takeover, the application starts before the service IP is fully available on the target node, causing connection failures. What is the best practice to address this?

A two-node cluster uses shared storage for application data. The team wants to reduce the time required to take over the application after a node failure by avoiding full filesystem checks at mount time when it is safe to do so. Which approach aligns with PowerHA best practices?

After replacing a network adapter on one node, the node no longer joins the cluster. The logs indicate heartbeat failures and the interface name changed (for example, en1 became en2). What is the most appropriate corrective action?

A customer needs to protect an application using shared SAN LUNs and wants automatic storage failover if one of two SAN fabrics fails. Which configuration best meets this requirement?

An administrator wants a resource group to run only on one preferred node, but still fail over to the other node automatically if the preferred node fails. When the preferred node returns, the administrator wants the resource group to move back automatically. Which resource group behavior should be configured?

A cluster is configured with application monitoring. The application intermittently hangs without terminating, and the business requires an automatic recovery action. Which monitoring approach is most appropriate?

A two-node cluster uses shared disks and has split-brain risk if communication is lost. The architect wants to ensure that in a partition, only one node continues to access shared storage. Which mechanism best addresses this requirement?

A PowerHA cluster uses storage-based replication (non-shared disks). During a site failover test, the resource group fails to start on the DR node because the replicated volume group is not varyon-able due to stale metadata and missing device definitions. What is the most appropriate preventive design step?

During a planned maintenance window, an administrator wants to move a resource group from NodeA to NodeB without triggering an automatic fallback later when NodeA returns to normal. Which setting best ensures the resource group remains on NodeB until an administrator decides otherwise?

A new two-node PowerHA cluster is being planned. The network team requires that service IP addresses must remain stable and move between nodes during failover. Which networking approach is the recommended design to meet this requirement?

After a failover test, an application comes online on the standby node but clients intermittently connect to the old node for several minutes. No errors appear in the application logs. Which action is most likely to reduce client misdirection immediately after IP takeover?

A cluster uses shared SAN LUNs with concurrent access disabled (only one node should varyon the volume group at a time). During a takeover, the resource group fails to acquire the volume group, and logs indicate the disks appear "busy". What is the best corrective action to prevent this in future failovers?

An administrator wants a single resource group to bring online: (1) a shared volume group, (2) a file system, and (3) an application that depends on that file system. Which configuration best enforces the correct startup sequence during failover?
