IBM PowerHA SystemMirror V7.2 Implementation Practice Exam: Test Your Knowledge 2025

An organization is planning to implement PowerHA SystemMirror for their critical database application. They need to ensure that the cluster can automatically recover from node failures. Which prerequisite must be satisfied before installing PowerHA SystemMirror?

A PowerHA administrator needs to configure a resource group that will support application failover between two nodes. The application requires a specific service IP address and a volume group. What type of resource group should be configured?

During a PowerHA implementation, an administrator discovers that the cluster verification utility reports persistent node communication errors. Network connectivity tests show that ping works between nodes. What is the most likely cause?

A financial institution requires that their PowerHA cluster maintains data consistency across geographically dispersed sites. They need asynchronous replication with minimal performance impact on the production system. Which PowerHA feature should be implemented?

What is the primary purpose of the PowerHA SystemMirror Cluster Aware AIX (CAA) component?

An administrator is configuring network settings for a PowerHA cluster and needs to ensure that the cluster can detect and respond to network failures quickly. Which network attribute should be tuned to reduce the time to detect network failures?

A company has a two-node PowerHA cluster with shared storage. During a planned maintenance window, the administrator needs to perform updates on one node while keeping applications running. What feature should be used?

When designing a PowerHA solution for an application that requires simultaneous access to shared data from multiple nodes, which storage configuration and resource group type combination is most appropriate?

A PowerHA cluster experiences an unexpected split-brain scenario where both nodes believe they should own the resources. Which mechanism does PowerHA use to resolve this situation?

An administrator needs to configure application monitoring in PowerHA to ensure that a custom database application is functioning correctly. The application has a specific process that must be running. What is the recommended approach?

During PowerHA installation planning, an architect must determine the minimum number of network interfaces required for a production two-node cluster following IBM best practices. How many network interfaces per node should be planned at minimum?

A PowerHA cluster's clstat command shows that one node is in the STABLE state while another node is in the ST_STABLE state. What does this output indicate?

An organization needs to implement a three-site disaster recovery solution with automatic failover between the primary and secondary sites, while the tertiary site serves as a backup. What PowerHA configuration approach should be used?

After synchronizing a PowerHA cluster configuration, an administrator notices that changes made on one node are not reflected on another node. Which command should be run to diagnose the cluster synchronization status?

A company wants to configure their PowerHA cluster to automatically vary off volume groups during a node failure and vary them on when bringing up resources on the takeover node. Which resource type must be configured in the resource group?

An administrator is planning storage for a new PowerHA implementation. The application requires high I/O performance and the ability to survive disk failures. Which storage configuration provides the best balance of performance and reliability?

During a PowerHA cluster configuration, what is the significance of defining a service IP address label versus a boot IP address?

An enterprise is implementing PowerHA for an application that requires storage replication between two data centers located 100 kilometers apart. The business requirement mandates zero data loss. Which replication solution and configuration should be implemented?

A PowerHA administrator receives alerts that a resource group is flapping between nodes, failing over and back repeatedly. What is the most likely cause and appropriate first troubleshooting step?

An organization is planning a PowerHA implementation and needs to ensure compliance with change management policies. Which PowerHA feature helps track and document cluster configuration changes?
