• A. operating system
• B. communication
• C. set of sensors
• D. none of the mentioned

Explanation: A monitoring system needs observations of its surroundings, which it obtains through a set of sensors.

• A. Process Pipeline
• B. Environmental Control
• C. Observe and React
• D. None of the mentioned

Explanation: A process pipeline divides processing into sequential stages, with each stage assigned to a separate processor or core so different items…

• A. data distributing system
• B. data acquisition system
• C. data collector system
• D. none of the mentioned

Explanation: High-speed data acquisition systems commonly use process pipelines because incoming data can pass through collection, processing, and…

• A. Movement detector
• B. Door sensor
• C. Window sensor
• D. All of the mentioned

Explanation: A commercial burglar alarm may combine movement detectors with door and window sensors to detect different forms of intrusion.

• A. Asynchronous communication
• B. Observe and React
• C. Environmental Control
• D. Process Pipeline

Explanation: Observe-and-react, environmental-control, and process-pipeline patterns are commonly cited real-time architectural patterns.

• A. object-oriented systems
• B. architectural design
• C. SRS
• D. Both object-oriented systems and Architectural design

Explanation: UML was created primarily to model object-oriented systems, including their structure and behavior, and it is also used to document…

• A. Using large-grain components improves performance but reduces maintainability
• B. Introducing redundant data improves availability but makes security more difficult
• C. Localizing safety-related features usually means more communication so degraded performance
• D. All of the mentioned

Explanation: Each option describes a trade-off between competing quality attributes, such as performance versus maintainability or availability versus…

• A. model-view-controller
• B. architecture pattern
• C. repository pattern
• D. none of the mentioned

Explanation: The repository pattern provides a shared data store through which interacting components can exchange and access data.

• A. physical
• B. development
• C. logical
• D. process

Explanation: The process view describes the system at runtime, including interacting processes, threads, and communication.

• A. type of application
• B. distribution of the system
• C. architectural styles
• D. testing the system

Explanation: Architectural decisions cover the application type, system distribution, and selected architectural styles.

• A. architecture
• B. repository pattern
• C. model-view-controller
• D. different operating system

Explanation: Model-view-controller manages interaction by separating the data model, user interface, and controller logic.

• A. physical
• B. development
• C. logical
• D. process

Explanation: The logical view models the system’s important abstractions, commonly represented as objects or classes and their relationships.

• A. physical
• B. logical
• C. process
• D. all of the mentioned

Explanation: The physical view describes the system’s hardware configuration and maps software components onto processors or other hardware nodes.

• A. Objects are abstractions of real-world
• B. Objects can't manage themselves
• C. Objects encapsulate state and representation information
• D. All of the mentioned

Explanation: Objects are abstractions that encapsulate state and behavior and can manage their own state through operations.

• A. Complexity Metrics
• B. Cohesion Metrics
• C. Morphology Metrics
• D. Coupling Metrics

Explanation: Component-level design metrics commonly measure complexity, cohesion, and coupling.

• A. Aggregation
• B. Inheritance
• C. Dependency
• D. All of the mentioned

Explanation: An is-a relationship means that one class is a specialized form of another, which is modeled through inheritance.

• A. maximum number of nodes at any level
• B. longest path from the root to a leaf
• C. number of modules
• D. lines of control

Explanation: In an arc-to-node ratio, a denotes the number of arcs, while n denotes the number of nodes.

• A. Active Object
• B. Passive Object
• C. Multiple instance
• D. None of the mentioned

Explanation: A passive object waits for another object to request an operation or provide data, whereas an active object can initiate activity…

• A. Inheritance
• B. Polymorphism
• C. Encapsulation
• D. Abstract Classes

Explanation: Generalization represents a broader superclass and more specialized subclasses; programming languages implement this relationship through…

• A. Aggregation
• B. Polymorphism
• C. Inheritance
• D. All of the mentioned

Explanation: Polymorphism lets related objects respond to the same method name in different ways, usually through overridden methods in subclasses.
