Question 1

Choose the correct answer.

What is common practice when integrating software models into SysML system models?



Answer : C

The common practice when integrating software models into SysML system models is to define cross-relationships between a UML software model and a SysML system model. A cross-relationship is a dependency that indicates a link between elements in different models or domains. By using cross-relationships, one can establish traceability and consistency between the software model and the system model without having to merge or transform them. Cross-relationships can also support allocation of software components to hardware or other software components in the system model.

Question 2

Choose the correct answer.

What is a best practice to link actions of an activity in a SysML model to a software application described in a UML model?



Answer : D

The best practice to link actions of an activity in a SysML model to a software application described in a UML model is to use CallBehaviorActions in the UML model that call the actions in the SysML model. A CallBehaviorAction is an action that invokes a behavior and provides inputs and outputs. By using CallBehaviorActions, the software application can reuse the behavior defined in the SysML model without having to duplicate or copy it. This also ensures consistency and traceability between the models.

Question 3

Choose the correct answer

What does a model library add to a SysML model?



Answer : B

A model library is a package that contains reusable model elements that can be imported into other models. A model library can add common concepts to a SysML model, such as units, quantities, value types, etc. These concepts can be used to define properties and parameters of blocks and constraints in a consistent and standardized way.

Question 4

Choose the correct answer

A company is executing a large distributed engineering project. More than a dozen engineers are contributing to the system model, working from different locations spread across three time zones The lead engineer has decided that it is essential to maintain a single model. The department director has expressed concern that the project may have trouble employing its engineers productively while still maintaining configuration control of this common model.

Which configuration management strategy is likely to be most successful*?



Answer : C

This configuration management strategy is likely to be most successful because it allows the engineers to work on the system model collaboratively and concurrently, while maintaining configuration control and avoiding conflicts. A configuration management tool is a software tool that helps manage changes to model elements and track their versions and history. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By using a configuration management tool, the engineers can check out packages for editing, which locks the elements in that package and prevents other users from modifying them. The engineers can also view packages in read-only mode by any user at any time, which allows them to see the latest version of the model without affecting it. The engineers can also receive alerts when a package they are viewing has been modified and checked-in by another user, and see the changes highlighted. This way, the engineers can stay informed and synchronized with the model updates. By not allowing packages to remain checked out overnight, the engineers can avoid holding up the work of other users who need to access or modify those packages.

Question 5

Choose the correct answer.

Every night the computers at the data center of Bank F, located in Asia, must complete an analysis of the previous day s financial transaction dat

a. Bank F plans to merge with Bank G, located In South America, Increasing the volume of data by an order of magnitude. The design team charged with expanding the facilities to handle this additional load is modeling the data center with SysML using the MARTE profile

Which capability of MARTE will help determine whether the existing processors at the data center can handle the anticipated data increase?



Answer : A

The capability of MARTE that will help determine whether the existing processors at the data center can handle the anticipated data increase is support for schedulability analysis. Schedulability analysis is a technique for verifying that a set of tasks can be executed within given time constraints on a given platform. MARTE provides concepts and annotations for modeling tasks, resources, scheduling policies, deadlines, etc., and for performing schedulability analysis using various methods and tools.

Question 6

Choose the correct answer.

A modeling team supervisor has defined a stereotype of block named *projectBlock and wants to prevent any use of an unstereotyped block

What must the supervisor do?.



Answer : C

To prevent any use of an unstereotyped block, the supervisor must mark the extending stereotype with the {strict} keyword. This keyword indicates that only elements with this stereotype can be created as instances of the extended metaclass. In this case, only blocks with the stereotype <> can be created as instances of Block.

Question 7

Choose the correct answer.

A control unit aboard a ship sends commands to a remote-controlled submarine. which in turn sends messages to the ship after completing each major stage of its overall mission. For each distinct stage, the ship orders the submarine to perform a different set of operations. Completing any given stage takes a widely variable amount of time

Why it is appropriate to use the MARTE profile to model this system with SysML?



Answer : D

It is appropriate to use the MARTE profile to model this system with SysML because the control unit must order the submarine's operations in real time, which the MARTE profile makes it possible to model in SysML. MARTE is a UML profile that provides concepts and annotations for modeling and analyzing real-time and embedded systems. It supports modeling time-related properties and constraints, such as deadlines, periods, durations, clocks, etc., as well as resource-related properties and constraints, such as memory, CPU, power, etc. By using MARTE, one can capture the real-time requirements and behavior of the system and perform schedulability and performance analysis.
