C0000308 IBM Certified Solution Implementer – DataPower Gateway v7.6 Practice Exam
Exam Number: 4379 | Last updated April 17, 2026 | 369+ questions across 5 vendor-aligned objectives
Gateway implementers who configure IBM DataPower Gateway v7.6 for secure API and SOA workloads target the C0000308 credential. Unlike the v10 administrator track, this implementer exam focuses on service configuration, processing policy authoring, and the deployment-phase skills of getting a DataPower service from concept to production. Candidates should be fluent with style sheets, match rules, GatewayScript, and the crypto objects that protect traffic.
Harvesting 26% of the exam, Service Configuration covers Multi-Protocol Gateway, Web Service Proxy, and XML Firewall service creation. At 22%, Processing Policy covers style sheets, match rules, GatewayScript actions, and action chaining within rules. A further 20% targets Security Policy, covering crypto objects, certificates, AAA policies, and TLS configuration.
Fluting down the remaining domains, Transformation and Routing accounts for 18% and spans XSLT, JSON-to-XML transformations, dynamic routing, and error handling. Deployment and Troubleshooting represents 14% and spans configuration export and import, multistep probe, and trace-based debugging. Implementer questions reward practical troubleshooting judgment — know where to look first when a service misbehaves.

10 of 369+ questions
Question #1 - Service Configuration
A DataPower v7.6 implementer at Stonewick Bank must expose a SOAP web service with WSDL-driven schema validation.
Which DataPower v7.6 service type exposes the SOAP web service with WSDL-driven validation?
A) Use a generic TCP service
B) Create a Multi-Protocol Gateway without any WSDL binding
C) Create an XML Firewall without a schema
D) Create a Web Service Proxy, which binds to the WSDL, enforces schema validation, and drives processing policies per operation
Show solution
Correct answers: D – Explanation:
Web Service Proxy with WSDL binding is the DataPower v7.6 SOAP reference. MPG-without-WSDL, XML Firewall-without-schema, and generic TCP all miss the SOAP service type. Source: Check Source
Question #2 - Service Configuration
A v7.6 implementer at Whitmarch Insurance needs to expose a REST API through DataPower with policy-driven header transformation.
Which DataPower v7.6 service type fits the REST API with policy-driven header transformation?
A) Expose the REST API directly without DataPower
B) Use a Web Service Proxy despite the API being REST-not-SOAP
C) Configure a Multi-Protocol Gateway with processing policies containing match rules and transform actions, routing the HTTP traffic per the configured URL patterns
D) Use a storage service
Show solution
Correct answers: C – Explanation:
MPG with processing policies is the DataPower v7.6 REST service-configuration reference. WSP for REST, direct exposure, and storage services all fail the pattern. Source: Check Source
Question #3 - Service Configuration
A v7.6 implementer at Braysmere Financial must configure an XML-only service that rejects inputs not matching the expected schema.
Which DataPower v7.6 service type rejects XML inputs that don’t match the schema?
A) Use a Multi-Protocol Gateway without schema validation
B) Use an XML Firewall service with an XML Manager and XSD-driven schema-validation action, rejecting non-conforming inputs at the gateway
C) Accept every input regardless of schema
D) Skip DataPower entirely
Show solution
Correct answers: B – Explanation:
XML Firewall with schema validation is the DataPower v7.6 XML-rejection reference. MPG-without-schema, accept-everything, and no-gateway all fail the service-config pattern. Source: Check Source
Question #4 - Processing Policy
A v7.6 implementer at Halsbridge Trust needs to apply different processing policies to different URL patterns on one service.
Which v7.6 policy-construction approach fits?
A) Skip processing policy entirely
B) Write a single match rule that ignores the URL pattern
C) Put logic in the back-end and leave DataPower as a passthrough
D) Define multiple match rules in the processing policy, each with its own URL pattern and ordered list of actions (validate, transform, route), so each URL gets the right treatment
Show solution
Correct answers: D – Explanation:
Multiple per-URL match rules with action chains is the v7.6 processing-policy reference. One-rule, back-end-only, and no-policy all fail the pattern. Source: Check Source
Question #5 - Processing Policy
A v7.6 implementer at Pridemoor Retail needs custom validation logic not provided by stock actions.
Which v7.6 action type fits?
A) Skip validation and accept every input
B) Modify DataPower’s firmware directly
C) Use a GatewayScript action to implement the custom validation, keeping the logic maintainable and testable within the policy
D) Shell out to an external process from the appliance
Show solution
Correct answers: C – Explanation:
GatewayScript actions is the DataPower v7.6 custom-logic reference. Firmware edits, no-validation, and shelling out all fail policy authoring. Source: Check Source
Question #6 - Security Policy
A v7.6 service at Carreford Insurance must require mutual TLS between client and gateway.
Which v7.6 security configuration fits?
A) Configure a TLS profile with both a crypto identification credential (server) and a validation credential (client), and enable mutual authentication so both sides present certificates
B) Use TLS without mutual authentication
C) Run the service over plaintext HTTP
D) Disable TLS to simplify testing
Show solution
Correct answers: A – Explanation:
Mutual-auth TLS profile with ID validation credentials is the v7.6 mTLS reference. One-sided TLS, plaintext, and disabled TLS all fail mTLS. Source: Check Source
Question #7 - Security Policy
A v7.6 AAA policy at Stornmere Credit must authenticate via LDAP and authorize based on a role mapping.
Which v7.6 AAA configuration fits?
A) Skip AAA and expose the service unauthenticated
B) Configure the AAA policy’s identity step for LDAP authentication, the authentication step to verify credentials, and the authorization step to evaluate role mappings against the requested resource
C) Use only authentication, skipping authorization
D) Share one service account for every caller
Show solution
Correct answers: B – Explanation:
AAA identify-authenticate-authorize with LDAP and role mapping is the v7.6 reference. Unauth, auth-only, and shared accounts all fail AAA. Source: Check Source
Question #8 - Transformation and Routing
A v7.6 implementer at Pennworth Retail must transform incoming XML to JSON before forwarding to a REST back-end.
Which v7.6 action fits?
A) Use a Transform action with an XSLT or GatewayScript that converts XML to JSON, then route the resulting JSON to the REST back-end
B) Send XML to the REST back-end and hope it accepts
C) Let the back-end handle all transformation and skip DataPower
D) Drop XML and only accept JSON from the client
Show solution
Correct answers: A – Explanation:
Transform action with XSLT/GatewayScript for XML→JSON is the v7.6 transformation reference. XML-to-REST mismatch, back-end-only, and client-restriction all fail transformation. Source: Check Source
Question #9 - Transformation and Routing
A v7.6 implementer at Greystock Bank must route messages to different back-ends based on a field in the incoming message.
Which v7.6 routing approach fits?
A) Set the routing destination dynamically via a Transform action (or explicit route-action) that inspects the incoming field and sets the back-end URL accordingly
B) Hard-code a single back-end URL and ignore the message content
C) Let the client tell DataPower where to route
D) Skip routing and reject messages that need branching
Show solution
Correct answers: A – Explanation:
Dynamic routing via transform/route actions is the v7.6 routing reference. Hard-coded URLs, client-driven routing, and rejection all fail the pattern. Source: Check Source
Question #10 - Deployment and Troubleshooting
A v7.6 implementer at Ellsbridge Bank is debugging an intermittent service failure.
Which v7.6 diagnostic tool fits?
A) Restart the appliance on every failure
B) Enable the multistep probe on the service to capture each policy step’s input, variables, and output for failing transactions, with the probe bounded in scope to avoid impact
C) Guess at the issue without instrumentation
D) Disable logging to reduce noise
Show solution
Correct answers: B – Explanation:
Multistep probe is the DataPower v7.6 diagnostic reference. Restarts, guesses, and disabled logging all fail troubleshooting. Source: Check Source
