S0010600 IBM PowerHA SystemMirror V7.2.5 AIX Administrator Specialty Practice Exam
Exam Number: 4397 | Last updated April 17, 2026 | 352+ questions across 5 vendor-aligned objectives
PowerHA specialists who operate IBM PowerHA SystemMirror V7.2.5 on AIX target the S0010600 credential. The specialty exam validates your ability to design, configure, and operate high-availability clusters on IBM Power Systems — resource groups, application controllers, dependencies, and failover behaviors. Candidates should be fluent with AIX clustering concepts, Cluster Aware AIX, and the clmgr-based administration interface.
Soaking up 26% of the exam, Cluster Architecture covers Cluster Aware AIX, cluster types, repository disk, and networking requirements. At 22%, Resource Group Management covers resource-group creation, policy configuration, dependency modeling, and startup behavior. A further 20% targets Failover and Recovery, covering planned and unplanned failovers, node isolation handling, and cluster-healing behaviors.
Waxing the remaining domains, Storage and Replication accounts for 18% and spans GLVM, shared storage pools, and replicated-resource-group patterns. Administration and Troubleshooting represents 14% and spans clmgr operations, log analysis, and support diagnostics. Specialty questions reward real operational judgment — pick the answer that minimizes failover disruption over the theoretically purest recovery path.
Every answer links to the source. Each explanation below includes a hyperlink to the exact IBM documentation page the question was derived from. PowerKram is the only practice platform with source-verified explanations. Learn about our methodology →

10 of 352+ questions
Question #1 - Cluster Architecture
A PowerHA V7.2.5 specialist at Hampford Bank is building a new 2-node cluster on AIX.
Which V7.2.5 cluster-architecture foundation fits?
A) Omit the repository disk
B) Skip CAA and try to build a cluster with ad-hoc scripts
C) Use a single non-redundant network interface for heartbeat and client
D) Configure Cluster Aware AIX (CAA) as the cluster foundation, provision a repository disk accessible to both nodes, and define cluster networking with redundant IP paths for heartbeat and client traffic
Show solution
Correct answers: D – Explanation:
CAA repository disk redundant networking is the PowerHA V7.2.5 cluster-architecture reference. No-CAA, non-redundant networking, and no-repo-disk all fail cluster foundation. Source: Check Source
Question #2 - Cluster Architecture
A V7.2.5 admin at Carrigleigh Insurance must pick a cluster type for a two-site deployment.
Which V7.2.5 cluster-type concept fits?
A) Use unrelated clusters at each site with no PowerHA awareness
B) Use a standard local cluster for sites 500 km apart
C) Use a linked cluster (or appropriate stretched/standard cluster type per the V7.2.5 documentation) to span the sites with networking and replication that support the recovery objectives
D) Skip cluster types and run single nodes at each site
Show solution
Correct answers: C – Explanation:
Linked cluster (or equivalent site-aware type per V7.2.5) is the multi-site reference. Local-only, unrelated clusters, and single-node-per-site all fail multi-site clustering. Source: Check Source
Question #3 - Cluster Architecture
A V7.2.5 admin at Torridon Energy must configure networking for heartbeat to tolerate link failure.
Which V7.2.5 networking approach fits?
A) Provision redundant heartbeat paths (multiple networks or IP aliases) so a single link failure doesn’t cause false failover, and configure network monitoring in PowerHA to detect and react appropriately
B) Use one heartbeat link with no redundancy
C) Share the heartbeat with user traffic on a saturated link
D) Disable heartbeat entirely to avoid false positives
Show solution
Correct answers: A – Explanation:
Redundant heartbeat paths monitoring is the V7.2.5 networking reference. Single-link, saturated sharing, and disabled heartbeat all fail cluster networking. Source: Check Source
Question #4 - Resource Group Management
A V7.2.5 specialist at Dalesford Manufacturing defines a resource group containing an application, shared volume group, and service IP.
Which V7.2.5 resource-group management approach fits?
A) Place unrelated resources in a single giant RG for simplicity
B) Omit the application controller from the RG
C) Create the resource group with the VG, service IP, and application controller as members, configure startup/fallover/fallback policies per the workload’s requirements, and assign the RG to the appropriate participating nodes
D) Skip policies and accept default behavior without thought
Show solution
Correct answers: C – Explanation:
RG with VG service IP app controller tuned policies is the V7.2.5 RG reference. Missing app controller, giant RGs, and unthought defaults all fail RG design. Source: Check Source
Question #5 - Resource Group Management
A V7.2.5 admin at Fairlock Telecom has two RGs: DB and App, where App depends on DB.
Which V7.2.5 RG-management approach fits?
A) Ignore dependencies and start both RGs in parallel regardless
B) Model the dependency between the RGs so that App only starts after DB is online, and fails over appropriately if DB moves — using PowerHA’s RG-dependency configuration
C) Start App even if DB is not online
D) Combine App and DB resources into a single RG with no dependency logic
Show solution
Correct answers: B – Explanation:
Explicit RG dependency is the V7.2.5 reference. Parallel-start, ignore-DB, and forced-combination all fail RG dependency management. Source: Check Source
Question #6 - Resource Group Management
A V7.2.5 admin at Thornhurst Utility wants an RG to prefer its primary node but tolerate running on the secondary after failover.
Which V7.2.5 RG policy fits?
A) Set fallback to trigger immediately every time the primary comes back, regardless of impact
B) Set the startup policy to Online on Home Node Only (or equivalent) and the fallback policy to Never Fallback or Fallback to Higher Priority Node as the operational preference — balancing availability against service disruption from unnecessary fallback
C) Leave RG policies at default without considering workload needs
D) Set RG to never return to the primary under any condition
Show solution
Correct answers: B – Explanation:
Thoughtful startup/fallback policies matched to workload is the V7.2.5 reference. Reflex fallback, unconsidered defaults, and never-fallback all fail RG-policy tuning. Source: Check Source
Question #7 - Failover and Recovery
A V7.2.5 admin at Raintree Financial performs a planned failover for maintenance on the primary node.
Which V7.2.5 failover procedure fits?
A) Move the resource group(s) to the secondary via clmgr move resource group, verify the application starts on the secondary, complete the maintenance, and move the RG back during a controlled window per the cluster’s fallback policy
B) Power off the primary without moving RGs and hope for automatic failover
C) Skip the move and do maintenance with applications running
D) Move every RG simultaneously regardless of dependencies
Show solution
Correct answers: A – Explanation:
clmgr-driven planned move verification controlled return is the V7.2.5 planned-failover reference. Reflex power-off, live-maintenance, and mass-move-without-deps all fail planned failover. Source: Check Source
Question #8 - Failover and Recovery
A V7.2.5 cluster at Grayston Insurance experiences a network partition; the admin must decide recovery action.
Which V7.2.5 recovery behavior fits?
A) Manually start the RG on both nodes to maximize uptime
B) Rely on PowerHA’s node-isolation handling via CAA and repository disk — which prevents split-brain by denying the isolated node the ability to hold the resource group — and plan the admin’s recovery around the outcome of that arbitration
C) Disable the cluster entirely at the first sign of network issues
D) Ignore the partition and hope both sides work
Show solution
Correct answers: B – Explanation:
CAA repo-disk-based arbitration with planned recovery is the V7.2.5 partition-handling reference. Split-brain activation, cluster-disable, and ignore-and-hope all fail partition handling. Source: Check Source
Question #9 - Storage and Replication
A V7.2.5 deployment at Hollowcreek Bank spans two sites without SAN replication.
Which V7.2.5 storage-and-replication approach fits?
A) Use GLVM (Geographic Logical Volume Manager) for host-based replication of volume groups across sites, integrated with PowerHA Enterprise Edition for site-aware RG movement
B) Rely on the SAN layer to replicate even when no SAN replication exists
C) Skip replication and accept data loss on site failure
D) Use nightly rsync without PowerHA integration
Show solution
Correct answers: A – Explanation:
GLVM integrated with PowerHA EE is the V7.2.5 host-based replication reference. SAN-replication assumption, no-replication, and unintegrated rsync all fail storage-and-replication design. Source: Check Source
Question #10 - Administration and Troubleshooting
A V7.2.5 admin at Penwood Chemicals investigates a failed cluster event.
Which V7.2.5 troubleshooting approach fits?
A) Disable the cluster and rebuild it from scratch
B) Restart both nodes without diagnosis
C) Guess at the cause from cluster names alone
D) Use clmgr and the PowerHA logs (/var/hacmp/log and event logs) to reconstruct the timeline, then collect a snap (clsnap) bundle for IBM Support if the root cause isn’t obvious
Show solution
Correct answers: D – Explanation:
clmgr logs clsnap is the V7.2.5 admin/troubleshooting reference. Reflex restarts, name-based guessing, and rebuild-from-scratch all fail troubleshooting. Source: Check Source
