iSACA Cybersecurity Fundamentals Certification Practice Exam

Which of the following describes SCADA systems?

1. They are used for networking and database management

2. They control industrial processes and critical systems

3. They focus on user interface design

4. They manage IT support services for enterprises

The correct answer is: They control industrial processes and critical systems

The choice that states SCADA systems control industrial processes and critical systems accurately captures the primary function of SCADA (Supervisory Control and Data Acquisition) systems. SCADA systems are integral to the management of industrial operations, particularly in sectors such as energy, water treatment, manufacturing, and transportation. They monitor and control remote processes by gathering real-time data from sensors and devices, enabling operators to oversee operations effectively and make informed decisions based on the data collected. In industrial environments, SCADA systems provide functionalities such as data acquisition, real-time monitoring, and control, which are essential for maintaining efficient operations and ensuring safety. These systems play a crucial role in automating processes and providing operators with the tools they need to respond promptly to system alarms or failures. The other choices do not accurately describe SCADA systems. While networking and database management are relevant to many technology systems, they do not encapsulate the specific role of SCADA. User interface design is important for many software applications but is not the main focus of SCADA systems, which prioritize operational functionality instead. Similarly, managing IT support services is outside the scope of SCADA, which is primarily focused on operational technology (OT) in industrial control environments rather than information technology (IT) support.
