• Question 21:

  Choose the correct answer.

  A system engineer specializing in rigid body dynamics wants to model the laws of motion (LOM) so that they may be reused to analyze different types of systems. The LOM consist of the mathematical relations R1 and R2. shown here.

  (R1)s=ut + (1/2)at2

  (R2) v = u + at

  How should the system engineer represent and relate LOM. R1, and R2 in SysML?

  A. Create a block for each of LOM. R1 and R? Then create part properties in LOM that are typed by R1 and R?

  B. Create an activity for each of LOM. R1, and R2. Then, create actions in LOM that are typed by R1 and R2.

  C. Create a constraint block for each of LOM. R1. and R2 Then, create part properties in LOM that are typed by R1 and R2.

  D. Create a constraint block for each of LOM. R1, and R2- Then, create constraint properties m LOM that are typed by R1 and R2.

  Correct Answer: B

• Question 22:

  Choose the correct answer.

  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 b2 or b3 or b4

  B. (b1 or b?) and (b3 or b4)

  C. (b1 or b2) and b3 and b4

  D. The question cannot be answered because Activity Diagram Fragment 1 is ambiguous

  Correct Answer: C

• Question 23:

  Choose the correct answer.

  Which diagram shows that the control system block is in the namespace of the system block?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 24:

  Choose the correct answer. Given the following diagram:

  

  Which statement is true about the values of pressure for the bicycle parts front : Tire and rear : Tire?

  A. The pressure of each part is constrained to be 50 psi.

  B. if not redefined individually by each part, the value of pressure must be 50 psi.

  C. The values may be redefined, but they must be the same for both front and rear.

  D. To be other than 50 psi. instance specifications must be developed for front and rear tires.

  Correct Answer: C

• Question 25:

  Choose the correct answer

  How is a testCase used to validate a requirement?

  A. The testCase model element can be used in SystvIL but it only applies to software

  B. Validation of a requirement can be indicated using a satisfiedBy relationship to a testCase

  C. Only the verdict model element (which can be a property of a testCase) can have a verifies relationship to a requirement.

  D. A requirement can have a vehfiedBy relationship to a testCase even if the test has not yet been conducted or even fully specified

  E. testCase is part of the UML Testing Profile and cannot be used with SysML.

  Correct Answer: B

• Question 26:

  Choose the correct answer

  A system consists of two identical tanks each containing a different level of fluid. The tanks are connected together by a port at the bottom of each tank. This system is modeled m the following diagram:

  

  Which statement is true?

  A. The block Fluid, which types item property flow 1 ->2. has a value property press : Pressure with a default value of null

  B. The value property /rate : flow rate is a derived property, which accommodates calculating its value based on oilier properties

  C. Parts t1 and t2 each use part instances to redefine the value of property level : Height

  D. The value of /rate for item property flow 1->2 is positive for flow from t1 to t2. and negative for How in the other direction

  E. Both port p1 on pan t1. and port p1 on t2. must have values defined for value properties /rate and press

  Correct Answer: B

• Question 27:

  Choose the correct answer

  Which SysML construct is used in an activity diagram to associate an actor of a use case with the actions that actor performs?

  A. an activity partition enclosing the actions the actor performs

  B. an action allocation of the actor to the actions that actor performs

  C. an association Between the actor and the actions that actor performs

  D. an object node to represent the actor and object flows tying that actor to the actions it performs

  Correct Answer: D

• Question 28:

  Choose the correct answer.

  Where can a StateInvariant appear?

  A. on a lifeline in a sd

  B. on a transition in a stm

  C. on an object node In an act

  D. in the s rates compartment of a block on a bdd

  Correct Answer: A

• Question 29:

  Choose the correct answer.

  An engineer is building a model of a system that includes both Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) satellites.

  Which diagram fragment shows a well-designed set of domain stereotypes that can be applied to the blocks representing those system elements?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 30:

  A. whether component s0 subclasses component u3

  B. which parts of each component participate in the connection

  C. which parts of each component participate in a reference association

  D. whether any part that belongs to component s0 subclasses a pan that belongs to component u3

  Correct Answer: B
