In a system with a multitude of class dependencies, the following measures can be considered:

A) The dependencies between classes are the responsibility of the developers. No measures are required within the architecture: This is false. While developers do manage day-to-day class dependencies, architectural measures are necessary to address systemic issues in a mature system1.

B) Loosening of direct dependencies between classes through the introduction of interfaces: This is true. Introducing interfaces can decouple classes and allow for more flexible and maintainable code1.

C) Loosening of direct dependencies between classes through the introduction of factories: This is also true. Factories can provide a way to create instances of classes without specifying the exact class, thus reducing dependencies1.

These measures align with the iSAQB® SOFTWARE ARCHITECTURE – FOUNDATION LEVEL guidelines, which suggest that managing dependencies is crucial for maintaining and extending systems effectively1.

To demonstrate the suitability of building blocks for implementing a use-case scenario effectively, UML (Unified Modeling Language) diagrams are instrumental. Among the options:

• B: Sequence diagram is the most suitable choice because it shows how objects interact in a particular scenario of a use case, detailing the sequence of messages exchanged between objects to accomplish the functionality described in the use case. This makes it ideal for demonstrating the dynamic behavior of the system components in the scenario.

The techniques best suited to illustrate the interaction of runtime building blocks are:A. Activity diagrams - Useful for showing the flow of control among various activities and decisions in the system.B. Sequence diagrams - Ideal for depicting the order of messages exchanged between components or objects in a specific scenario.C. State diagram - Shows how a component or an object changes its state in response to events, highlighting dynamic behavior.G. Depiction of screen flows (sequence of user interactions) - Useful for visualizing the sequence of user interactions with the system, which is critical for user-centric design and runtime behavior analysis.
