C9006100 IBM Certified Administrator – WebSphere Application Server Network Deployment v9.0.5 Practice Exam
Exam Number: 4384 | Last updated April 17, 2026 | 388+ questions across 5 vendor-aligned objectives
Legacy-WAS administrators who operate WebSphere Application Server Network Deployment v9.0.5 at enterprise scale target the C9006100 credential. The exam validates end-to-end WAS ND administration — cell design, deployment manager operations, application deployment, security, and performance tuning. Candidates should be fluent with the admin console, wsadmin scripting, and the JVM tuning knobs that keep traditional WAS workloads performant.
Totaling 26% of the exam, Topology and Cell Management covers cells, deployment managers, node agents, application servers, and cluster configuration. At 22%, Application Deployment covers EAR installation, fine-grained update, mapping to clusters, and session management. A further 20% targets Security, covering global security, LTPA, LDAP integration, and JAAS.
Coping with the remaining domains, Performance and Tuning accounts for 18% and spans thread-pool tuning, JVM heap management, and HTTP plugin configuration. Monitoring and Troubleshooting represents 14% and spans PMI, logs, and the JVM Tuning Assistant. WAS administrators should expect scenario questions that cross-reference HTTP plugin behavior and cluster-member weight — the right answer often depends on whether session affinity is in use.

10 of 388+ questions
Question #1 - Topology and Cell Management
A WAS ND v9.0.5 admin at Brackenholm Bank must design a cell with a deployment manager, two nodes, and a cluster spanning them.
Which v9.0.5 topology construct fits?
A) Create a cell with a deployment manager, federate two nodes, and define a cluster with members on each node — so the cluster is resilient to single-node loss and deployments propagate via the deployment manager
B) Run one unmanaged application server and call it a cell
C) Federate nodes without a deployment manager
D) Skip clustering and run single instances
Show solution
Correct answers: A – Explanation:
DMgr federated nodes cross-node cluster is the WAS ND v9.0.5 topology reference. Unmanaged servers, DMgr-less federation, and single instances all fail ND topology. Source: Check Source
Question #2 - Topology and Cell Management
A v9.0.5 admin at Thornleigh Insurance needs the deployment manager to automate routine tasks using a script.
Which v9.0.5 admin interface fits?
A) Edit XML configuration files directly while the server is running
B) Only use the admin console click-by-click
C) Use wsadmin (Jython or Jacl) to script cell operations — create servers, deploy applications, update configurations — repeatably and under version control
D) Avoid scripting entirely and re-do tasks manually each time
Show solution
Correct answers: C – Explanation:
wsadmin with Jython/Jacl is the WAS ND v9.0.5 automation reference. Click-by-click only, direct XML edits, and manual repetition all fail admin automation. Source: Check Source
Question #3 - Topology and Cell Management
A v9.0.5 admin at Brandholm Credit must add a new application server to an existing cluster.
Which v9.0.5 admin action fits?
A) Install the application only on the new member and forget the cluster mapping
B) Create the server but never synchronize nodes
C) Create a new application-server member in the cluster via the admin console (or wsadmin), map applications to the cluster so new members inherit app mappings, and synchronize nodes so the member receives config and applications
D) Skip creation and hope an existing server takes the extra load
Show solution
Correct answers: C – Explanation:
Cluster member add app mapping node sync is the WAS ND v9.0.5 reference. No-sync, forgotten mapping, and skipping all fail cluster member management. Source: Check Source
Question #4 - Application Deployment
A v9.0.5 admin at Mossgate Utility must deploy an EAR to the cluster.
Which v9.0.5 admin approach fits?
A) Skip resource-reference mapping and hope defaults work
B) Copy the EAR into one node’s filesystem and skip the install step
C) Install the EAR only to one server and call the cluster done
D) Install the EAR via the admin console (or wsadmin), map modules to the target cluster, map resource references to data sources, synchronize nodes, and start the application
Show solution
Correct answers: D – Explanation:
Admin console (or wsadmin) install cluster mapping resource mapping sync start is the v9.0.5 deployment reference. File copies, single-server installs, and skipped mappings all fail deployment. Source: Check Source
Question #5 - Application Deployment
A v9.0.5 admin at Prestonvale Finance needs to update a single JSP in a deployed EAR without redeploying the entire app.
Which v9.0.5 feature fits?
A) Use fine-grained update to install only the changed module or file, so the rest of the application continues running and only the targeted artifact is updated
B) Redeploy the full EAR for every one-file change
C) Copy the JSP directly into the deployed application directory without admin-console awareness
D) Restart the entire cell for a single JSP change
Show solution
Correct answers: A – Explanation:
Fine-grained update is the WAS ND v9.0.5 targeted-update reference. Full redeploys, filesystem copies, and full restarts all fail fine-grained update. Source: Check Source
Question #6 - Application Deployment
A v9.0.5 admin at Alderbridge Mutual must ensure HTTP sessions survive loss of a cluster member.
Which v9.0.5 session-management capability fits?
A) Use local-only sessions and accept loss on failover
B) Enable session persistence via Memory-to-Memory replication or Database persistence so sessions are replicated across cluster members and survive a failure
C) Store sessions in application files on disk
D) Skip sessions entirely
Show solution
Correct answers: B – Explanation:
M2M replication or DB persistence is the WAS ND v9.0.5 session reference. Local-only, disk files, and no-sessions all fail session survivability. Source: Check Source
Question #7 - Security
A v9.0.5 admin at Hillmarsh Insurance must enable administrative security with LDAP-backed authentication.
Which v9.0.5 admin configuration fits?
A) Enable global security without configuring a user registry
B) Enable global security, configure an LDAP user registry with the appropriate base DN and bind credentials, enable LTPA as the authentication mechanism, and restart the deployment manager and servers for the configuration to take effect
C) Keep default file-based user registry with a single admin user forever
D) Disable administrative security to simplify
Show solution
Correct answers: B – Explanation:
Global security LDAP registry LTPA restart is the WAS ND v9.0.5 admin-security reference. No-registry, file-only, and disabled security all fail admin security. Source: Check Source
Question #8 - Security
A v9.0.5 application requires JAAS configuration for a custom login module.
Which v9.0.5 admin capability configures JAAS for the custom login module?
A) Configure a JAAS application login entry in the admin console referring to the custom login module class, and package or bundle the login module so WAS can load it at runtime
B) Skip JAAS and hard-code credentials
C) Disable authentication for the application
D) Put the login module only on one node and not share it
Show solution
Correct answers: A – Explanation:
JAAS application login module packaging is the WAS ND v9.0.5 custom-auth reference. Hard-coded creds, disabled auth, and partial deployment all fail JAAS. Source: Check Source
Question #9 - Performance and Tuning
A v9.0.5 admin at Ravenwood Insurance sees a cluster member OutOfMemoryError in the heap during peak traffic.
Which v9.0.5 performance adjustment fits first?
A) Blindly double the heap without analyzing
B) Analyze heap dumps with a tool (e.g., IBM ISA, MAT) to identify the leaking or growing objects, then tune JVM heap size and GC policy per the findings — avoiding blind heap increases
C) Disable GC to ‘speed things up’
D) Restart the cluster member every hour as a workaround
Show solution
Correct answers: B – Explanation:
Heap analysis informed heap/GC tuning is the WAS ND v9.0.5 performance reference. Blind heap-doubling, disabled GC, and periodic restart workarounds all fail performance practice. Source: Check Source
Question #10 - Monitoring and Troubleshooting
A v9.0.5 admin at Galesworth Bank needs to gather runtime performance metrics.
Which v9.0.5 admin capability gathers runtime performance metrics?
A) Log every request to a flat file and analyze manually
B) Rely on SSH into nodes to guess at CPU
C) Skip monitoring entirely
D) Enable PMI (Performance Monitoring Infrastructure) with appropriate modules and consumption via the admin console, Tivoli Performance Viewer, or a management platform that queries PMI
Show solution
Correct answers: D – Explanation:
PMI monitoring consumer is the WAS ND v9.0.5 metrics reference. SSH guesses, no-monitoring, and flat-file logs all fail metrics practice. Source: Check Source
