 A methodology is a set of principles, methods and practices that guide the execution of a project or activity. A systems engineering project always involves some kind of methodology, even if it is not explicitly defined or documented. Working spontaneously or randomly is also a form of methodology, although it may not be very effective or efficient. A systems engineering project cannot be conducted without applying any methodology at all.

The kind of models that can be exchanged using XMI are instances of MOF models. MOF (Meta-Object Facility) is a standard that defines a metamodeling architecture and a set of metamodels for creating and manipulating models. A metamodel is a model that defines the abstract syntax and semantics of another model. A model is an instance of a metamodel that conforms to its rules and constraints. XMI (XML Metadata Interchange) is a format specification that enables the interchange of objects and models through an XML formatted file. It is based on a metamodel that defines the mapping of MOF concepts to XML concepts. By using XMI, any model that is an instance of a MOF metamodel can be serialized and deserialized in terms of XML elements and attributes. This includes UML, SysML, and other modeling languages that are defined as MOF metamodels. References: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.omg.org/spec/XMI/2.5.1/About-XMI/

The typical stakeholder views of a design are composed of both behavioral and structural diagrams, depending on the purpose and perspective of the view. Behavioral diagrams show how the system or part behaves or interacts in different scenarios or states, such as activity, state and sequence diagrams. Structural diagrams show how the system or part is composed of parts, ports, connectors and properties, such as block definition and internal block diagrams. Both types of diagrams are important to convey the functionality and architecture of the system or part to different stakeholders. Use case and requirements diagrams are not sufficient to populate the stakeholder views of a design, as they only capture the functional and non-functional aspects of the system or part.

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.

The diagram fragment that correctly shows a SysML Block extending a basic UML Class is Option B. This option shows a Block with the stereotype <<block>> applied to it. This stereotype indicates that the Block is an extension of the Class metaclass. The Block inherits all the features of the Class, such as attributes, operations, associations, etc., and adds additional features specific to SysML, such as ports, flows, values, constraints, etc. References: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://sysml.org/sysml-faq/what-is-block-definition-diagram.html

The information that is required to define a viewpoint in SysML in addition to stakeholders is concerns, languages, methods, and purpose. Concerns are aspects of interest about a system that are addressed by a viewpoint. Languages are notations or modeling techniques used by a viewpoint to represent a view. Methods are processes or guidelines for constructing or interpreting views that conform to a viewpoint. Purpose is an explanation of why and how a viewpoint addresses stakeholder concerns.
