Broadcom Service Virtualization Technical Specialist (250-574) Certification Sample Questions

01. A credit bureau's consumer sends requests in which two optional fields are sometimes present and sometimes absent, and the fields have no bearing on which response the provider returns. Matching is configured to require the full recorded structure.
What is the consequence?
a) The service will quietly fill in the missing fields from the recorded transaction before it attempts to match
b) Optional fields are excluded from comparison by definition, so nothing changes
c) Requests that differ only in whether an irrelevant field is present will fail to match
d) The service will match on whichever fields it recognizes and then log all of the rest as unexpected

02. During playback, a deployed virtual service receives a request that is not an exact match for any transaction in its image.
What determines the response the caller receives?
a) The request is rejected at the environment and the caller receives a transport-level error, because only exactly recorded requests can be served.
b) The model's matching rules, or its defined response for unmatched requests.
c) The Registry decides which deployed virtual service should answer, and that service returns its first recorded transaction.
d) The Enterprise Dashboard's monitoring rules decide which recorded response the caller receives.

03. A team has been building against a virtual service authored from an agreed contract. The providing team now changes the contract.
What does the consuming team have to do?
a) Nothing at all, because the stand-in reflects what was agreed at the time and so remains a perfectly valid baseline
b) Wait for the provider to be built and test against that instead
c) Re-record the stand-in from the provider's new implementation
d) Update the stand-in to the new contract, or keep testing against a shape nobody will deliver

04. An intermittent defect surfaces only when a downstream account service returns one particular error response. That response appears rarely in the shared environment and cannot be forced there.
Why is a virtual service the better place to chase this defect?
a) The virtual service can be configured to return that error response on demand, so the developer can reproduce the failure at will
b) A virtual service removes the network hop, which is where intermittent faults originate
c) The live downstream service holds the authoritative business logic, so reproducing the fault there is the only way to show it is genuine rather than an artifact of the stand-in
d) Rare errors are non-deterministic and cannot be reproduced anywhere

05. Which two characteristics distinguish a virtual service from a simple hand-written stub inside a test suite?
(Choose two)
a) It validates that the consumer's requests conform to the provider's contract
b) It removes the need for the consumer to handle error responses
c) Its behavior can be derived from observing real traffic rather than written by hand
d) It runs as a deployable service that any consumer can reach over the real protocol

06. A healthcare software vendor prepares a reduced patient dataset for its application developers. Before releasing it, administrators check that no unrelated hospital’s records were pulled in.
Which activity are they performing?
a) Validation of the subset
b) Refresh of the extract
c) Reservation of records for a run
d) Masking of the fields

07. A virtual service can be authored to answer a given request with a fault or error payload instead of a successful result.
What is the purpose of doing this?
a) To signal to the environment that the model needs re-recording against the provider
b) To reduce the size of the virtual service image before deployment
c) To prevent the recorded transactions from being replayed in the wrong order
d) To exercise the consumer's error handling paths

08. A food delivery platform has an integration suite that passes on most runs and fails on perhaps one in six, always on assertions about a restaurant's opening hours returned by a partner directory.
How does replacing that partner with a virtual service address the failures?
a) Tests that depend on upstream partner data are automatically marked as skipped for the remainder of that run
b) The returned data becomes the same on every run, so a failure means the code changed
c) The failing assertions are retried automatically, several times over, until the run eventually comes back green
d) The partner's own opening-hours records get corrected at source, so that every later run finds them consistent

09. A public-sector tax authority has forty automated tests. Several fail intermittently, and investigation shows each failure happens only when a particular earlier test ran first and left a filing record behind.
What property are those tests missing?
a) Ordering — the suite should pin the tests into the one sequence that reliably makes all of them pass
b) Coverage — more tests are needed so the intermittent cases are exercised deliberately
c) Independence — each test should establish and clean up the state it needs rather than inherit it
d) Assertion strength — the checks are far too specific about which filing records they expect to find in place

10. An engineer is asked which artifacts are needed before a recorded provider can be stood up as a running stand-in.
Which two are required?
(Choose two)
a) A service image holding the recorded request and response transactions
b) An environment able to run the service and answer on an endpoint
c) A copy of the provider's deployment package
d) Live network access to the provider during playback
