OMG Exam OMG-OCSMP-MBI300 Topic 6 Question 62 Discussion

Actual exam question for OMG's OMG-OCSMP-MBI300 exam

Question #: 62
Topic #: 6

Choose the correct answer.

A system engineer has created the following model of a tank system composed of two tanks and a pipe connecting them:

The system engineer wants to mathematically relate the flow of water through the pipe using the following mass conservation equation: Tank_System wFlowin flowRate * Tank_System pipe endA_Area = Tank_System wFlowOut flowRate * Tank_System pipe endB_Area How would the system engineer model this in SysML?

ACreate a block to represent the mass conservation equation, use it in Tank_System. and relate its properties to the properties of wFlowin. wFlowOut. and pipe

BCreate a constraint block to represent the mass conservation equation, use it in Tank_System. and relate its parameters to the properties of wFiowin. wFlowOut. and pipe

CCreate a constraint block to represent each of wFlowin wFlowOut and the mass conservation equation; use these constraint blocks In Tank_System. and relate their parameters to the properties of pipe.

DCreate two flow properties for Tank_System (equivalent to wFlowin and wFlowOut); create a constraint block for the mass conservation equation and use it in Tank_System. and then relate the flow properties to the new constraint property.

EIt is not possible to model this because wFlowin and wFlowOut are item properties and not flow properties

This question is a real state-of-the-art conundrum! I'm going to have to consult my UML pocket guide for this one.

B for sure! As an avid UML enthusiast, I can say with confidence that StateInvariants belong on transitions in state machines.

I believe the correct answer is A) on a lifeline in a sd because StateInvariant represents a condition that must be true at that point in the interaction.

Hmm, I'm not sure about this one. Maybe C? Object nodes in activity diagrams seem like a reasonable place for a StateInvariant.
