A. operating system
B. communication
C. set of sensors
D. none of the mentioned
Explanation: If some exceptional event or sensor state is detected by the system, the monitoring system takes some action. Often, this involves raising an alarm to draw an operator’s attention to the event.
A. Data Extraction Transformation & Loading
B. Data Execution Transformation & Loading
C. Extraction Transformation & Loading
D. Execution Transformation & Loading
A. Process Pipeline
B. Environmental Control
C. Observe and React
D. None of the mentioned
Explanation: The Process Pipeline pattern makes this rapid processing possible by breaking down the required data processing into a sequence of separate transformations, with each transformation carried out by an independent process.
A. data distributing system
B. data acquisition system
C. data collector system
D. none of the mentioned
Explanation: Data acquisition systems collect data from sensors for subsequent processing and analysis.
A. Movement detector
B. Door sensor
C. Window sensor
D. All of the mentioned
Explanation: A burglar alarm system for commercial buildings include movement detectors in individual rooms, door sensors that detect corridor doors opening, and window sensors on ground-floor windows that can detect when a window has been opened
A. Asynchronous communication
B. Observe and React
C. Environmental Control
D. Process Pipeline
Explanation: These patterns can be combined and you will often see more than one of them in a single system.
A. object-oriented systems
B. architectural design
C. SRS
D. Both object-oriented systems and Architectural design
Explanation: The UML was designed for describing object-oriented systems and, at the architectural design stage, you often want to describe systems at a higher level of abstraction
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: High availability architecture can be affected by several design factors that are required to be maintained to ensure that no single points of failure exist in such design.
A. model-view-controller
B. architecture pattern
C. repository pattern
D. none of the mentioned
Explanation: The majority of systems that use large amounts of data are organized around a d database or repository.
A. physical
B. development
C. logical
D. process
Explanation: This view is useful for making judgments about non-functional system characteristics such as performance and availability.
