Comprehensive and Detailed In-Depth Explanation:

Theblack diamond notationinArchiMaterepresents aComposition relationship, which is used to indicatewhole-part relationshipsbetween elements.

Financial Processingis thewhole(parent element).

X, Y, and Zaresub-functions, meaning they arepart ofFinancial Processing.

Compositionisa strong relationship, meaning thesub-functions (X, Y, and Z) do not exist independently outside Financial Processing.

Analysis of Answer Choices:

✅A. The financial processing function is composed of three sub-functions X, Y, and Z.→✅Correct Answer

Composition relationshipsin ArchiMate indicate that one element ispart of anotherin a strict, whole-part hierarchy.

ArchiMate 3.2 Specification, Section 6.4.2, definesComposition as a structural relationship where the child elements belong strictly to the parent.

SinceFinancial Processing contains X, Y, and Z as integral sub-functions, this is the correct choice.

✅B. The financial processing function aggregates the three sub-functions X, Y, and Z.→❌Incorrect

Aggregationis aweakerrelationship in ArchiMate compared toComposition.

In Aggregation,the sub-functions can exist independently, whereas in Composition, theycannot.

ArchiMate 3.2 Specification, Section 6.4.1, states thatAggregation does not enforce a strict whole-part relationshiplike Composition does.

✅C. The financial processing function is influenced by the three sub-functions X, Y, and Z.→❌Incorrect

Influence relationshipsin ArchiMatedo not represent whole-part structures.

Influence is amotivation relationship, meaning it represents animpact or effect, not astructural dependency.

✅D. The financial processing function is assigned the three sub-functions X, Y, and Z.→❌Incorrect

Assignment relationshipsare used to indicate thata behavior element (e.g., function, process) is performed by an active structure element (e.g., role, actor, component).

This diagramdoes not depict an assignment relationship; instead, itshows a structural composition.

Final Answer:✅A. The financial processing function is composed of three sub-functions X, Y, and Z.

Comprehensive and Detailed In-Depth Explanation:

This diagram represents aTechnology Layer modelin ArchiMate, whereX and Z are servers, andE is a shared technology component.

X and Z are likely hardware devices (Servers), which are typically represented as Technology Nodes or Devices in ArchiMate.

E is a shared resource that both servers connect to, implying a common storage or network area storage device.

According toArchiMate 3.2,Technology Objects like Storage Devices or Infrastructure Services can be shared across multiple devices.

Analysis of Answer Choices:

✅A. The servers, represented by devices, are connected by a communication network.→❌Incorrect

There isno explicit network symbol(e.g., a communication path or a network node).

Therelationship between X, Z, and E indicates a shared resource rather than a network connection.

ArchiMate 3.2 Specification, Section 6.6.4, definesCommunication Networksseparately, and none are present here.

✅B. The servers are shown in the technology interaction E, where they collectively process data.→❌Incorrect

Technology Interaction represents behaviorin ArchiMate, meaning two or more active elements arecollaborating on a process.

E is a shared object, not an interaction process.

✅C. The servers share a common network area storage device E.→✅Correct Answer

E is a shared resource, meaningit is likely a storage device used by both servers.

ArchiMate 3.2 Specification, Section 6.6.2, states thatTechnology Objects can represent storage elementsused by multiple devices.

Thismatches the pattern of a shared Network Attached Storage (NAS) or Storage Area Network (SAN).

✅D. Technology collaboration E represents a point of access for services offered by the servers.→❌Incorrect

Technology Collaboration elementsrepresentactive behavior, not astatic resourcelike a shared storage system.

E does not behave as a collaboration element but as a shared infrastructure object.

Final Answer:✅C. The servers share a common network area storage device E.

 This is because the diagram shows the three main categories of relationships in ArchiMate: structural relationships, which model the static construction or composition of concepts; dependency relationships, which model how elements depend on or use other elements; and dynamic relationships, which model the temporal or causal connections between elements.
