C0006401 IBM Certified Solution Architect – WebSphere Hybrid Edition V5.0 Practice Exam
Exam Number: 4372 | Last updated April 17, 2026 | 366+ questions across 5 vendor-aligned objectives
Hybrid-edition architects who design WebSphere Hybrid Edition V5.0 solutions independent of the OpenShift bundle target the C0006401 credential. This standalone exam focuses on the WebSphere Hybrid Edition architecture itself — Liberty deployment modes, traditional WAS co-existence, and the portfolio-level licensing that makes Hybrid Edition distinctive. Candidates should understand the WAS product lineage, migration pathways, and runtime positioning within WHE.
Cornering 26% of the exam, WHE Portfolio and Licensing covers the Hybrid Edition entitlement model, traditional-to-Liberty migration paths, and deployment-mode selection. At 22%, Liberty Architecture covers feature sets, server.xml configuration, collective management, and MicroProfile selection. A further 20% targets Traditional WAS Integration, covering ND topologies, deployment manager and node agents, and co-existence patterns.
Fastening the remaining domains, Migration Planning accounts for 18% and spans Transformation Advisor reports, tWAS-to-Liberty migration, and data-source portability. Security and Performance represents 14% and spans JAAS, LDAP integration, thread-pool tuning, and HTTP plugin configuration. Because this exam sits upstream of the OpenShift bundle, avoid answering from OpenShift-first assumptions — traditional WAS topology is still very much on the exam.

10 of 366+ questions
Question #1 - WHE Portfolio and Licensing
A WebSphere Hybrid Edition V5.0 architect at Clarbrook Bank is explaining the entitlement model to a procurement team.
Which WHE V5.0 licensing statement reflects the documented model?
A) WHE V5.0 licenses Liberty and traditional WebSphere as two independent entitlements only
B) WHE V5.0 provides a single entitlement covering Liberty, traditional WebSphere, and related components, letting enterprises mix runtimes within the same entitlement rather than licensing each separately
C) WHE V5.0 licenses only Liberty — traditional WAS must be purchased separately
D) WHE V5.0 has no entitlement model at all
Show solution
Correct answers: B – Explanation:
Single blended entitlement covering Liberty traditional WAS is the WHE V5.0 licensing reference. Independent entitlements, Liberty-only coverage, and ‘no entitlement’ all misstate the model. Source: Check Source
Question #2 - WHE Portfolio and Licensing
A WHE V5.0 architect at Highbrough Insurance must recommend deployment modes for the modernization roadmap.
Which V5.0 deployment-mode selection fits?
A) Recommend deployment modes per application — Liberty on OpenShift for cloud-native, Liberty on classic servers where OpenShift isn’t yet available, and traditional WAS for applications needing its specific capabilities — within the shared entitlement
B) Mandate Liberty on OpenShift for every application regardless of readiness
C) Mandate traditional WAS for every application regardless of benefit
D) Skip selection and randomly assign runtimes
Show solution
Correct answers: A – Explanation:
Per-application mode selection within the shared entitlement is the WHE V5.0 reference. Mandates in either direction and random assignment all fail portfolio selection. Source: Check Source
Question #3 - Liberty Architecture
A Liberty architect at Mosswood Financial must control which features are loaded at runtime.
Which V5.0 Liberty configuration fits?
A) Load every available feature whether the application uses it or not
B) Declare the needed features in server.xml’s
C) Skip feature declaration and rely on random defaults
D) Hard-code features in application source
Show solution
Correct answers: B – Explanation:
server.xml featureManager declarations is the Liberty V5.0 reference for feature selection. Load-everything, random defaults, and source hard-coding all fail Liberty architecture. Source: Check Source
Question #4 - Liberty Architecture
A Liberty V5.0 deployment at Ashenvale Insurance needs centralized management of multiple Liberty servers.
Which V5.0 capability fits?
A) Use a Liberty collective with a collective controller and member servers, or equivalent orchestration (operator on OpenShift), so configuration and operations are managed centrally
B) Manage each Liberty server individually with no central control
C) Share a single server.xml across unrelated servers
D) Manually SSH into each server for every change
Show solution
Correct answers: A – Explanation:
Liberty collective management (or operator orchestration) is the V5.0 centralized-management reference. Individual-server management, shared unrelated config, and SSH-per-change all fail the pattern. Source: Check Source
Question #5 - Traditional WAS Integration
A WHE V5.0 architect at Hollarch Mutual must design a traditional WAS ND topology for a co-existing application.
Which ND topology fits?
A) Run a single unmanaged application server with no deployment manager
B) Use a deployment manager plus node agents plus application servers, deploying the application to a cluster with an HTTP plugin in front, following traditional WAS ND topology
C) Skip ND and use only Liberty for every application
D) Run the application without any WAS runtime
Show solution
Correct answers: B – Explanation:
Deployment manager node agents application servers HTTP plugin is the traditional WAS ND topology reference. Unmanaged single servers, Liberty-only, and no-runtime all fail traditional WAS design. Source: Check Source
Question #6 - Traditional WAS Integration
A WHE V5.0 co-existence pattern at Fernholm Bank must let Liberty and traditional WAS share identity across SSO boundaries.
Which V5.0 approach fits?
A) Disable authentication on one runtime to simplify flow
B) Maintain separate user stores per runtime and require repeated logins
C) Integrate both runtimes with the corporate LDAP via their respective user registries, and use a shared SSO token (LTPA or OAuth) so users authenticate once and flow between Liberty and traditional WAS applications
D) Share a single admin account across all users
Show solution
Correct answers: C – Explanation:
Shared LDAP SSO token (LTPA/OAuth) is the WHE V5.0 co-existence SSO reference. Separate stores, disabled auth, and shared admin all fail SSO design. Source: Check Source
Question #7 - Migration Planning
A WHE V5.0 architect at Penhurst Credit is planning a tWAS-to-Liberty migration.
Which V5.0 migration-planning tool fits?
A) Abandon migration planning entirely
B) Guess at migration complexity without tooling
C) Migrate every application simultaneously
D) Run Transformation Advisor across the tWAS estate to identify migration complexity and the Liberty features each application needs, then sequence the migration in waves driven by the findings
Show solution
Correct answers: D – Explanation:
Transformation Advisor-driven planning is the V5.0 migration-planning reference. Guesses, big-bang migration, and abandonment all fail migration discipline. Source: Check Source
Question #8 - Migration Planning
A WHE V5.0 tWAS-to-Liberty migration at Ridgemount Insurance has a data-source dependency (Db2 on z/OS) that must keep working.
Which V5.0 migration practice fits?
A) Ignore data-source portability and hope it works
B) Leave the tWAS data source in place and point Liberty at it via magic
C) Drop the data-source dependency
D) Port the tWAS data-source configuration to Liberty’s dataSource element with the appropriate JDBC driver, connection-pool parameters, and credential mechanism, and verify with functional tests before cutover
Show solution
Correct answers: D – Explanation:
Ported dataSource with pool settings and credentials plus verification is the V5.0 migration reference. Magic pointing, dropped deps, and hope all fail migration. Source: Check Source
Question #9 - Security and Performance
A Liberty V5.0 application at Gladhurst Bank must tune its thread-pool to avoid timeouts under peak load.
Which V5.0 Liberty practice fits?
A) Use single-threaded execution to simplify
B) Leave thread-pool defaults regardless of load
C) Adjust the executor’s coreThreads and maxThreads in server.xml (or use the autonomic executor default) per observed queue depth and response-time measurements, validating under load test
D) Disable threading entirely
Show solution
Correct answers: C – Explanation:
Measured executor tuning with validation is the Liberty V5.0 performance reference. Defaults-regardless, single-threaded, and disabled threading all fail performance tuning. Source: Check Source
Question #10 - Security and Performance
A traditional WAS front-end at Poolwick Insurance uses the HTTP plugin to route traffic from IBM HTTP Server to the app server cluster.
Which V5.0 admin practice fits?
A) Regenerate and propagate the HTTP plugin configuration after topology changes, and tune ServerIOTimeout and ConnectTimeout in the plugin-cfg.xml per observed behavior
B) Leave the plugin configuration outdated after topology changes
C) Remove the plugin and expose the app server directly
D) Edit the plugin config randomly and hope
Show solution
Correct answers: A – Explanation:
Plugin regeneration plus timeout tuning is the WHE V5.0 HTTP plugin reference. Outdated plugins, direct exposure, and random edits all fail plugin admin. Source: Check Source
