A team is using MBT for a system that is being developed incrementally. In the first iteration, the test objective is to verify the core functionality. In the second iteration, the objective is to verify edge cases and error handling. The team has limited modeling resources. What is the best approach?

Create a model only for edge cases, as they are more important

Create a single comprehensive model at the start that covers both core functionality and edge cases

Create a model only for core functionality and never extend it

Create a model for core functionality in the first iteration, then extend the model to include edge cases in the second iteration

A company is developing a mobile banking app. Stakeholders have expressed that the most critical aspect is security, specifically that unauthorized users must never access accounts. Which test objective should be derived from this stakeholder need to guide MBT modeling?

Verify that the app is compatible with the latest mobile operating systems

Verify that the app meets performance benchmarks under high load

Verify that all security mechanisms (e.g., authentication, authorization) prevent unauthorized access

Verify that all account balances are displayed correctly to authorized users

In model-based testing, what is the primary role of test objectives when creating an MBT model?

To define the exact test data values that will be used in every test case

To specify the programming language and tools used to implement the model

To determine the scope and focus of the model by identifying what behaviors and aspects of the system must be represented

To replace the need for a separate test plan by providing all testing details

A team is using MBT for a system with a very large state space. The test objective is to verify that the system correctly handles all error conditions. However, modeling all error conditions would result in an extremely large and complex model. What is the best approach?

Model all error conditions, regardless of the model size

Use a higher level of abstraction to group similar error conditions, reducing model complexity while still covering the key error types

Model only the most common error conditions and ignore the rest

Use a random test generation approach without a model

What is the primary source for deriving test objectives in an MBT project?

The personal preferences of the test team lead

Stakeholder needs and project goals

The internal implementation details of the system

The test automation tool's capabilities

Certified Tester Model-Based Testing

Part of the MBT Modeling domain, which makes up ~27% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~7–11 in this domain), expect 1–1 from this objective — we provide 22 practice questions to prepare you well beyond it.
