Given the model composed of the following diagram:

The modeler has set all shown values us inputs and next intends to solve the mode that is, to calculate the outputs. Assume nothing relevant has been left out.
What is wrong with this model?

• A.Both easel and case2 should not be underlined.
• B.The modeler set a1 as an input value in case1.
• C.The slash (/) in property a1 of BlockA is an error that paramethes will assume to be a division sign.
• D.Block A cannot be used by both easel and case2.

What is one key advantage of using SysML parametrics versus traditional derived properties?

• A.it takes many more steps to specify derived properties in the typical tool compared to specifying constraint blocks.
• B.A derived property requires an additional constraint expression, whereas SysML parametrics does not.
• C.SysML parametrics supports non causal expressions, whereas a derived property involves an expression with a fixed output direction
• D.OCL-based constraint expressions can be used with SysML parametrics but not with derived properties

Consider the following two activity diagram fragments labeled Fragment 1 and Fragment 2. The JoinSpecification for Fragment 1 is completely specified, but the JoinSpecification for Fragment 2 is not.

Which join specification for Fragment 2 will make it exhibit the same behavior as fragment 1? Assume that activities with the same names exhibit the same behavior

• A.(b1 or b?) and (b3 or b4)
• B.b1 or b2 or b3 or b4
• C.(b1 or b2) and b3 and b4
• D.The question cannot be answered because Activity Diagram Fragment 1 is ambiguous
