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?

A. Create 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

B. Create 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

C. Create 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.

D. Create 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.

E. It is not possible to model this because wFlowin and wFlowOut are item properties and not flow properties

The essentials of a laptop battery capacity model are shown In the following diagrams (where the value types W, h and Wh stand for watl, hour, and watt-hour respectively). Assume that the instance values shown are inputs, and that nothing relevant has been omitted.

The designer needs to determine what the energy_capacity of battery 1 should be to enable a laptop usage_time_capacity time of 8 hours. Which combination of the options listed in the text box in the figure will achieve this Intent with minimal changes (including minimal new aspects)?

A. O1.1 and O2 1

B. O1.1 and O2 2

C. O1 1 and O2 3

D. O1.2 and O2.1

E. O1 7 and O2.2

F. O1.2 and O2.3

G. O1 3 and O2 3

How ate use cases and requirements used for requirements analysis in SysML?

A. in a SysML model, either use cases or requirements are modeled, but never both

B. Use cases are a relic from UML and are. strictly speaking, useless in a SysML model

C. Use cases are good for capturing functional requirements. For nonfunctional requirements, the requirement element is needed

D. Use cases are the basis for all requirements in a model. Requirements refine the use cases by adding additional information through then properties.

There is a requirement to count and prioritize widgets. While it is active, the action that implements this behavior will repeatedly accept a widget and immediately output a prioritized widget. A special "final" widget will cause the action to terminate and output the total count of widgets It processed Which activity diagram fragment shows this action along with its inputs and outputs?

A. Option A

B. Option B

C. Option C

D. Option D

Choose the correct answer.

What are streaming parameters?

A. parameters that are mapped to flow ports

B. parameters in which tokens are never buffered

C. parameters through which a continuous stream of tokens pass

D. parameters through which an activity can accept or produce tokens throughout its execution

Choose the correct answer.

To "show what you know" about SysML a Systems Engineer (SE) must take a total of four examinations in order Model User (MU). Model Bulkier Fundamental (MBF), Model Builder intermediate (MBI> and Model Builder Advanced (MBA). The SE must also study before taking each exam.

Which activity diagram fragment correctly uses object state constraints to document the process of studying and taking the exams, ensuring that the exams are taken in order of increasing difficulty, and allowing for the possibility that exams may have to be repeated?

A. Option A

B. Option B

C. Option C

D. Option D

Choose the correct answer.

Which SysML construct specifies a probability distribution to the values of a property such as a basic interval distribution between min and max?

A. a range property

B. an interval property

C. a probability property

D. a distributed property

Choose the correct answer.

Given the following diagram:

What is the significance of typing the connector with an association?

A. Only items compatible with Card Connection may pass over connector c1. There are no other implications

B. If SD Card and Card Reader blocks ever have ports, they must be compatible with the Card Connection association

C. Card Connection represents the pan that d uses to connect SD Card to Card Reader, eg the arrangement of contact points

D. An association must exist between the SD Card block and Card Reader block, and not just between parts in the Digital Picture Frame block.

Choose the correct answer.

Given the following diagram fragment:

What does the multiplicity at the actor end mean?

A. At most two Initiator actor instances can perform the use case

B. Two Initiator actor instances are required to trigger the use case

C. Two Initiator actor instances are required to participate in the use case.

D. Multiplicities carry no meaning on use case diagrams

Choose the correct answer

Which statement is true about the read only keyword when it appears next to a property?

A. It states that the corresponding property is provided for reading purposes only

B. It specifies that the corresponding property cannot be redefined

C. It specifies that the value of the corresponding property cannot change during the lifetime of its owner.

D. It specifies that the value of the corresponding property can be changed by its owner, but can only be read by other blocks
