Questions # 1:

Choose the correct answer.

Given the following diagram:

Question # 1

Which message ordering is valid?

Options:
A.

M1, M2. M3, M4

B.

M3. M1. M2, M4

C.

M3, M4. M1, M2

D.

None of these orderings is valid.

Questions # 2:

Choose the correct answer.

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

Options:
A.

A derived property requires an additional constraint expression, whereas SysML parametrics does not.

B.

OCL-based constraint expressions can be used with SysML parametrics but not with derived properties

C.

it takes many more steps to specify derived properties in the typical tool compared to specifying constraint blocks.

D.

SysML parametrics supports non causal expressions, whereas a derived property involves an expression with a fixed output direction

Questions # 3:

Choose the correct answer.

Assume the following state machine fragment Is In the A-State when the event evC arrives.

Question # 3

What is the order of behaviors that are executed after evj arrives?

Options:
A.

action 9, action 1

B.

action 2, action 9, action 1

C.

action 2, action 9, action 1, start activity X, evC

D.

stop activity X (if needed), action 2, action 9, action 1, start activity X

E.

stop activity X (If needed), action 2, action 9, action 1, action 4 start activity X

Questions # 4:

Choose the correct answer.

Given the following diagram:

Question # 4

What Is the meaning of the consider fragment?

Options:
A.

It is a constraint that prevents adding a nested ignore fragment for any one of ml. m2 or m3.

B.

It ignores all messages other than ml m2 and m3 in the scenario being described by the interaction

C.

The meaning is undefined because the diagram is ill-formed in the absence of n>3. which must be considered.

D.

It allows the invocation of the operations corresponding to messages m 1. m? and m3 only when they appear in that order

Questions # 5:

Choose the correct answer

How is a testCase used to validate a requirement?

Options:
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.

Questions # 6:

Choose the correct answer.

What are streaming parameters?

Options:
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

Questions # 7:

Choose the correct answer

What is an effective and efficient approach to project modeling standards and conventions?

Options:
A.

Every project should create its own domain specific profile to describe modeling standards and conventions

B.

Organizations should create specific modeling standards and conventions to ensure modeling consistency across projects

C.

The SysML specification alone is sufficient to describe modeling standards and conventions when the modeling tool has a proper implementation of SysML

D.

The SysML specification and the modeling tool documentation are sufficient to describe modeling standards and conventions

Questions # 8:

Choose the correct answer.

In the following bdd, A delegates both of its ports to B:

Question # 8

Which ibd correctly represents this?

A)

Question # 8

B)

Question # 8

Question # 8

Options:
A.

Option A

B.

Option B

C.

Option C

D.

Option D

Questions # 9:

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.

Question # 9

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

Options:
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

Questions # 10:

Choose the correct answer.

Given the following state machine fragment.

Question # 10

if it starts in F-State and then the event evB is received, what is the subsequent state?

Options:
A.

D-State

B.

E-State

C.

F-State

D.

G-Stale

E.

None: the diagram is ill-formed
