What is best practice to model a software application in a SysML model for a system?



Answer : A

The best practice to model a software application in a SysML model for a system is to use a block stereotyped with software to represent the software application and its interfaces. A block is a modular unit that encapsulates its structure and behavior and can be connected to other blocks via ports and connectors. A stereotype is an extension of an existing metaclass that adds additional information or semantics to a model element. By using a block stereotyped with software, the software application can be modeled as a system component with its own properties, operations, ports, flows, etc., and can be allocated to hardware blocks or other software blocks.

Question 2

Choose the correct answer Where may tagged values be defined?



Answer : B

Tagged values can be defined only as attributes of stereotypes. A tagged value is an extension of a model element with additional information that is not part of its standard properties. A tagged value is defined by an attribute of a stereotype that is applied to the model element. The attribute specifies the name and type of the tagged value.

Question 3

Choose the correct answer.

How should stereotypes be grouped to facilitate re-use in later projects?



Answer : A

Stereotypes should be grouped in profiles to facilitate re-use in later projects. A profile is a mechanism for extending UML or SysML with additional modeling elements that are not part of the standard language. A profile defines stereotypes, which are extensions of existing metaclasses. A profile can be applied to a model to make the stereotypes available for use. By grouping stereotypes in profiles, they can be easily reused in different models or projects.

Question 4

Choose the correct answer

What is the purpose of the Domain Metamodel in UPDM?



Answer : D

The purpose of the Domain Metamodel in UPDM is to define the metamodel concepts and relationships without any implementation. The Domain Metamodel captures the core concepts of DoDAF and MODAF in terms of entities, attributes, associations, and constraints. It does not specify how these concepts are implemented in UML, SysML, or any other language or tool. The Domain Metamodel serves as a requirements model for UPDM and provides traceability links between the domain concepts and the profile elements.

Question 5

Choose the correct answer.

What is a common rationale for defining and applying a profile to a SysML model?



Answer : B

A common rationale for defining and applying a profile to a SysML model is that the profile extends the model with reusable elements, such as units, quantities, value types, etc. These elements can be defined in a model library and imported into other models by applying the profile. This way, the profile enables consistent and standardized modeling of properties and parameters of blocks and constraints.

Question 6

Choose the correct answer.

A model is being built using constructs defined in a Quality profile Project requirements state that the model must only be built using the constructs defined In the Quality profile - no other metaclasses may be used.

Which diagram fragment correctly expresses this requirement?

A)

C)

D)



Answer : C

The diagram fragment that correctly expresses the requirement that the model must only be built using the constructs defined in the Quality profile is Option C. This option shows an apply relationship between the model and the profile with the {strict} keyword applied. This means that only elements with stereotypes from the Quality profile can be created as instances of the extended metaclasses. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.ibm.com/docs/SSB2MU_8.2.0/com.ibm.rhp.sysml.doc/topics/rhp_c_dm_sysml_profile_features.html


Question 7

Choose the correct answer.

A modeling team supervisor wishes to force modelers to use particular metamodeling features

What must the supervisor do?



Answer : C

To force modelers to use particular metamodeling features, the supervisor must apply the profile to the model with the {strict} keyword applied. This keyword indicates that only elements with stereotypes defined in the profile can be created as instances of the extended metaclasses. For example, if a profile defines a stereotype <<quality>> as an extension of Class, then only classes with this stereotype can be created as instances of Class when the profile is applied with the {strict} keyword.
