B. "import" the profile to the model with the {required} keyword applied
C. "import" the profile to the model with the {strict} keyword applied
D. "apply" the profile to the model with the {strict} keyword applied

Choose the correct answer
How is the concept of coupling used to assess model quality?
A. Low coupling leads to poor model quality because all parts of a system must be properly coupled in order to measure the completeness of the model
B. High coupling leads to good model quality provided all blocks in a structural model exhibit the same average degree of coupling
C. Coupling has no bearing on model quality because no metrics exist for measuring the level of coupling of SysML models
D. High coupling leads to poof model quality because it decreases reuse potential and prevents independent modification of system elements

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*?
A. Use a centralized repository for the model files Allow only engineers in the eastern-most time zone to upload changes to the model files in the mornings, and the western engineers in the afternoons. Either can download and view the model files at any time. This will assure maximum productivity while minimizing the possibility of collisions
B. Co-locate the modeling team Trying to maintain configuration of a model across a distributed team is extremely difficult and may not succeed
C. Use a configuration management tool to manage model elements. Assign ownership of model elements at the package level- Only the owner of a package may make changes to elements in that package Note that each relationship between model elements must be contained within a single package
D. Use a configuration management tool to manage model elements. Allow packages to be checked out by any user for editing, which locks the elements therein contained Packages may be viewed in read-only mode by any user at any time All model users receive alerts when a package they are viewing has been modified and checked-in. and changes are highlighted Packages may not remain checked out overnight

A senior engineer has been assigned to set up a SysML model for the development of a medical device. Many stakeholders are involved, ranging from the development team to management, quality assurance, and regulatory experts. All must use the model Which choice defines a set of common tasks that will prepare the model for the stakeholders?
A. 1) Define and apply appropriate profiles
2) Create a package structure that covers the relevant aspects
3) Set up a modeling center of excellence who builds the model for the stakeholders.
B. 1) Define viewpoints for the different stakeholder concerns and set up conformant views
2) Set up model access rights (read/write/delete) for the different stakeholder groups
3) Nominate a model builder for each stakeholder group.
C. Define and apply appropriate profiles
2) Define viewpoints for the different stakeholder concerns and set up conformant views
3) Create a package structure that covers the relevant aspects
D. 1) Define one common set of SysML elements for all stakeholders.
2) Create a package structure that covers the relevant aspects
3) Set up model access rights (readVwrite/delete) for the different stakeholder groups

Choose the correct answer.
What is a common rationale for defining and applying a profile to a SysML model?
A. The profile enables separate views of the model for the different stakeholder concerns.
B. The profile extends the model with reusable elements, e.g. units.
C. The profile adds appropriate metainformation to the model to allow automated system analysis
D. The profile makes the model suitable for a modeling tool
