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 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
• 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 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
• 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

What is a fundamental goal of UPDM?

• A. to define a common means of expressing DoDAF and MODAF architectures so that they can be modeled solely in SysML
• B. to define a common means of expressing DoDAF and MODAF architectures using the same underlying metamodel
• C. to capture the common aspects of MODAF and DoDAF elements, removing the elements and views that are not common
• D. to separate the DoDAF and MOOAF metamodels but give them a common underpinning by creating a separate UML profile for each of them within UPDM

Choose the correct answer.
What is a common rationale for defining and applying a profile to a SysML model?

• A. The profile extends the model with reusable elements, e.g. units.
• B. The profile makes the model suitable for a modeling tool
• C. The profile enables separate views of the model for the different stakeholder concerns.
• D. The profile adds appropriate metainformation to the model to allow automated system analysis

Choose the correct answer.
What is common practice when integrating software models into SysML system models?

• A. The software is specified with SysML in the SysML system model.
• B. Cross-relationships are defined between a UML software model and a SysML system model
• C. A model-to-model transformation integrates a UML software model into a SysML system model
• D. The software is specified with UML in the SysML system model

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 data. 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?

• A. support for embedded systems such as the processors
• B. support for comparative analysis of processor architectures
• C. support for schedulability analysis
• D. support for modeling scheduled events that occur in different time zones
