OMG-OCSMP-MBI300 Exam - Topic 1 Question 19 Discussion

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

Question #: 19
Topic #: 1

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

E seems too dismissive, there has to be a way to model it.

Wait, is it really not possible to model this? Sounds off.

I’m leaning towards D, seems more comprehensive.

I think option B makes the most sense for modeling the equation.

I feel like option D makes sense since it talks about creating flow properties, but I'm not sure if that's the best way to relate everything in Tank_System.

I’m a bit confused about whether we should create separate constraint blocks for each flow or just one for the mass conservation equation.

I think option B sounds familiar because it mentions using a constraint block, which we practiced in a similar question about energy conservation.

I remember we discussed something about constraint blocks in class, but I'm not entirely sure if it's the right approach here.

I feel pretty good about D. The /etc/login.defs file is where you define things like password length, complexity, and expiration, so that seems like the most likely place Myron would need to go.

Hmm, this seems like a tricky one. I'll need to think through the key characteristics of an aggregation to determine which statement is true.

I'm a bit confused about the licensing grace period; I thought it was 30 days, but maybe it's actually 15?
