C9003400 IBM Certified Solution Architect – Cloud Pak for Business Automation v21.0.3 Practice Exam
Exam Number: 4359 | Last updated April 17, 2026 | 386+ questions across 5 vendor-aligned objectives
Business-automation architects who design Cloud Pak for Business Automation v21.0.3 solutions target the C9003400 credential. The exam validates your ability to pick the right CP4BA capability for each automation need, compose capabilities into end-to-end solutions, and defend the design against operability, compliance, and cost reviews. Candidates should be fluent with Business Automation Workflow, Automation Decision Services, Content Services, and Operational Decision Manager.
Marshaling 26% of the exam, Solution Design covers business-process modeling, capability selection, end-to-end flow design, and the trade-off between orchestration and choreography. At 22%, Deployment Topology covers operator patterns, OpenShift sizing, multi-site topologies, and v21.0.3-specific constraints. A further 20% targets Integration, covering REST APIs, IBM MQ, event integration, and the content-ingestion surface.
Framing the final sections, Governance and Versioning accounts for 18% and spans automation-asset versioning, CoE governance, and testing strategies. Security and Identity represents 14% and spans LDAP integration, role-based access, and audit. v21.0.3 has behavioral differences from v24.0.0 — read scenario questions carefully for version cues before committing to an answer.

10 of 386+ questions
Question #1 - Solution Design
A v21.0.3 architect at Langcombe Insurance is designing a claims-triage solution that runs scored rules and routes cases to adjusters.
Which v21.0.3 solution-design selection fits?
A) Model the scoring logic in Automation Decision Services for rule authoring by business analysts, and orchestrate routing and human steps in Business Automation Workflow
B) Hard-code scoring in Java and keep routing there too
C) Put scoring and routing in a shared Excel sheet
D) Skip automation and keep claims manual
Show solution
Correct answers: A – Explanation:
ADS for rules plus BAW for orchestration is the v21.0.3 solution-design reference. Hard-coded Java, Excel, and no-automation all fail the pattern. Source: Check Source
Question #2 - Solution Design
A v21.0.3 end-to-end flow at Bridgewood Retail mixes synchronous approval tasks with async event-driven steps.
Which v21.0.3 orchestration-vs-choreography decision fits?
A) Use orchestration for the step-ordered, human-approval portions and choreography for loosely-coupled asynchronous events, combining them where the flow benefits from each style
B) Use orchestration for everything regardless of coupling needs
C) Use choreography for everything including ordered approvals
D) Skip the choice and improvise per step
Show solution
Correct answers: A – Explanation:
Orchestration-for-order plus choreography-for-loose-coupling is the v21.0.3 solution-design reference. Single-style-for-all and improvisation all fail design. Source: Check Source
Question #3 - Deployment Topology
A v21.0.3 admin at Crestmarsh Bank is sizing the OpenShift cluster for a full CP4BA deployment.
Which v21.0.3 deployment-topology approach fits?
A) Follow the v21.0.3 sizing guide per capability (BAW, ODM, ADS, CSS), aggregate the requirements, and add headroom for bursts and upgrades
B) Use a single small node and scale only after failure
C) Ignore sizing because operators will autoscale
D) Size only for BAW and ignore other capabilities
Show solution
Correct answers: A – Explanation:
Per-capability sizing aggregated with headroom is the v21.0.3 topology reference. Under-sized nodes, autoscale-only, and capability omission all fail topology design. Source: Check Source
Question #4 - Deployment Topology
A v21.0.3 multi-site design at Wrenfield Insurance must tolerate loss of one data center.
Which v21.0.3 topology fits?
A) Rely on nightly tape backups alone
B) Deploy one cluster with no DR
C) Run two clusters without synchronization
D) Deploy CP4BA v21.0.3 on two OpenShift clusters across sites, replicate persistent data per the v21.0.3 multi-site reference, and drill failover regularly
Show solution
Correct answers: D – Explanation:
Multi-cluster CP4BA with replication and drills is the v21.0.3 DR-topology reference. Single-cluster, unsynced clusters, and tape-only all fail the requirement. Source: Check Source
Question #5 - Integration
A v21.0.3 workflow at Marnley Bank must consume messages from an on-premises IBM MQ queue.
Which v21.0.3 integration pattern fits?
A) Poll the queue from a script and email results
B) Use the v21.0.3 MQ integration from BAW to consume messages transactionally, preserving delivery semantics from producer to consumer
C) Screen-scrape the MQ admin UI
D) Skip MQ and ask producers to rewrite to REST
Show solution
Correct answers: B – Explanation:
BAW MQ integration with transactional semantics is the v21.0.3 integration reference. Script polling, screen-scraping, and upstream rewrites all fail the requirement. Source: Check Source
Question #6 - Integration
A v21.0.3 architect at Elsmere Credit must expose BAW to an external REST consumer with authentication and audit.
Which v21.0.3 integration design fits?
A) Skip audit because integration is internal-only
B) Open an unauthenticated REST endpoint on the public internet
C) Expose BAW via REST integration with OAuth or similar auth, log every call to the CP4BA audit facilities, and version the interface
D) Share a single long-lived token across all consumers
Show solution
Correct answers: C – Explanation:
Authenticated REST with audit and versioning is the v21.0.3 integration reference. Unauth, no-audit, and shared tokens all fail baseline integration security. Source: Check Source
Question #7 - Governance and Versioning
A v21.0.3 CoE at Bonbridge Holdings must prevent untested automations from reaching production.
Which v21.0.3 governance practice prevents untested automations from reaching production?
A) Disable governance entirely
B) Let teams promote whatever they want to production
C) Promote only on Fridays without tests
D) Enforce automation-asset versioning plus a test-gated promotion pipeline so only tested versions progress from dev to production
Show solution
Correct answers: D – Explanation:
Versioning plus test-gated promotion is the v21.0.3 governance reference. Unrestricted promotion, day-based gating, and disabled governance all fail quality. Source: Check Source
Question #8 - Governance and Versioning
A v21.0.3 asset-reuse effort at Pickmere Insurance needs a shared library of decision services across teams.
Which v21.0.3 CoE governance practice enables shared reusable decision services across teams?
A) Copy-paste decision logic between teams
B) Publish reusable ADS decision services into a governed asset library with versioning and CoE review before teams adopt them
C) Forbid reuse entirely
D) Publish without review or versioning
Show solution
Correct answers: B – Explanation:
Governed asset library with versioning is the v21.0.3 CoE reference. Copy-paste, no-reuse, and ungoverned publishing all fail governance. Source: Check Source
Question #9 - Governance and Versioning
A v21.0.3 testing requirement at Hooklands Bank must run automated regression tests on automations before promotion.
Which v21.0.3 governance practice adds automated regression testing to promotion?
A) Test only manually just before release
B) Add an automated regression-test stage to the CP4BA promotion pipeline, failing promotions that break existing tests, with results captured for audit
C) Skip regression testing to save time
D) Rely solely on production observability to catch regressions
Show solution
Correct answers: B – Explanation:
Automated regression tests in the pipeline is the v21.0.3 governance reference. Manual-only, skipping, and production-only detection all fail the requirement. Source: Check Source
Question #10 - Security and Identity
A v21.0.3 deployment at Thorton Heath Insurance must integrate with corporate LDAP for authentication.
Which v21.0.3 security configuration fits?
A) Share a single admin account
B) Create local accounts for every user
C) Configure LDAP on the Cloud Pak foundational services identity provider and map LDAP groups to CP4BA capability roles
D) Disable auth on capability UIs
Show solution
Correct answers: C – Explanation:
Foundational-services LDAP with group-to-role mapping is the v21.0.3 identity reference. Local accounts, shared admin, and disabled auth all fail baseline controls. Source: Check Source
