1. 1An engineering handbook lists the tasks needed to achieve an objective but deliberately leaves the techniques for carrying out each task to project teams. In the PMTE terminology, what does that task sequence define?

   1. A.A method
   2. B.A processCorrect answer: B
   3. C.A tool
   4. D.An environment

   Explanation: Estefan defines a process as a "logical sequence of tasks" and says it defines what is to be done. B matches the task sequence. A supplies how a task is performed; C supports performing a method; D supplies the surrounding conditions. Those are different PMTE roles.

2. 2A team wants author and revision metadata on selected model elements, rather than distinct values for each physical system instance. Which customization is most appropriate?

   1. A.A subclass carrying per-instance system state
   2. B.A stereotype carrying model-element metadataCorrect answer: B
   3. C.A value type specifying a physical unit
   4. D.A constraint block relating system values

   Explanation: The SysML specification states, "Where the extensions include properties that describe modeling data, not system data.". B fits model metadata. A is appropriate for system-instance properties; C for values/units; D for mathematical relationships among system properties.

3. 3A software team translates a SysML structural model into familiar UML notation. Which pair correctly identifies the UML diagram kinds most closely corresponding to a block definition diagram and an internal block diagram, respectively?

   1. A.Object diagram and deployment diagram
   2. B.Class diagram and composite structure diagramCorrect answer: B
   3. C.Package diagram and object diagram
   4. D.Composite structure diagram and class diagram

   Explanation: The specification says the two diagrams are "similar to the UML class diagram and composite structure diagram respectively". B preserves both correspondences. A and C substitute other UML structures; D reverses the definition-level and internal-structure roles.

4. 4A MARTE-annotated UML model must be analyzed by a tool with a different input format. Which forward path matches MARTE's model-driven tool-chain approach?

   1. A.Transform analysis results into XMI and then import them into the UML tool.
   2. B.Export the annotated model as XMI, transform it, then run the analysis tool.Correct answer: B
   3. C.Export XMI, treat it directly as computed analysis results, then transform those results.
   4. D.Run the analysis tool before supplying a model, then generate the input XMI.

   Explanation: "The forward path shows the way the model is expected to be transformed via the XMI output, to a format readable by an analysis tool." A: This is a feedback direction rather than the requested forward path. B: XMI to analysis-format transformation is the stated forward path. C: An exported model is not an already-computed result. D: Analysis requires the model input rather than preceding it.

5. 5A project has already decided to evaluate alternative architectures. Its lead now specifies the techniques for carrying out that evaluation. Which PMTE element is the lead defining?

   1. A.The environment
   2. B.The lifecycle model
   3. C.The methodCorrect answer: C
   4. D.The tool

   Explanation: The source states, "A Method (M) consists of techniques for performing a task". C therefore describes how the evaluation will be done. A concerns surrounding conditions, B organizes lifecycle development, and D is an instrument supporting a method; none is the specified set of techniques.

6. 6A customization requires notation beyond the standard stereotype notation. Which extension directly specifies that notation?

   1. A.An abstract-syntax extension definition
   2. B.A profile-application relationship
   3. C.A diagram extension specifying concrete notationCorrect answer: C
   4. D.A model-library class definition

   Explanation: "concrete syntax uses notation other than the standard stereotype notation" A: Abstract syntax identifies constructs and relationships rather than their new symbols. B: Profile application enables use but does not itself specify additional notation. C: Diagram extensions specify concrete syntax beyond standard stereotype notation. D: Reusable class content does not define new diagram notation.

7. 7A system-to-software handoff must carry both textual requirements with satisfaction links and engineering equations relating block properties. Which two additions to UML's diagram taxonomy directly provide these SysML representations?

   1. A.Use case and activity diagrams
   2. B.Package and sequence diagrams
   3. C.Requirement and parametric diagramsCorrect answer: C
   4. D.State machine and internal block diagrams

   Explanation: SysML calls the requirement diagram a construct for "textbased requirements" and says the parametric diagram "describes the constraints among the properties associated with blocks." C matches both needs. A describes usage and behavior; B organization and interactions; D states and internal structure rather than the requested pair.

8. 8A modeler enters a required response-time limit before running analysis, although response time is an output property. How should a MARTE integration interpret that entered value?

   1. A.As the computed response-time prediction
   2. B.As an input workload parameter rather than a response requirement
   3. C.As a required output value to compare with the computed responseCorrect answer: C
   4. D.As an uncertain execution parameter for a sensitivity study

   Explanation: "the modeler may also input required values of output properties, which can be used to determine how well the system meets its requirements" A: A target is not the computed prediction. B: A response-time target is not the input workload. C: Required output values support the stated requirement assessment. D: The entered required limit is not an uncertain execution parameter.

9. 9An enterprise combines its engineering processes, the techniques used within those processes, and supporting tools into a repeatable approach for a class of projects. What has it assembled?

   1. A.A methodologyCorrect answer: A
   2. B.A modeling language
   3. C.An acquisition milestone
   4. D.A single method

   Explanation: The report defines a methodology as a "collection of related processes, methods, and tools". A fits that combined approach. B supplies modeling notation and meaning, C is a decision point, and D is a technique-level contribution rather than the whole combination.

10. 10A team must restrict a user model to UML metaclasses directly referenced by SysML. Which choice implements that restriction?

    1. A.Apply the SysML profile strictly.Correct answer: A
    2. B.Import the SI units model library.
    3. C.Apply the SysML profile non-strictly.
    4. D.Import the Standard Profile L2 alone.

    Explanation: The SysML specification states, "only the UML metaclasses referenced by SysML are available". A invokes the strict-application restriction. B supplies units; C may allow additional metaclasses; D supplies another profile rather than enforcing SysML's restriction.
