Which term provides network interoperability and facilitates the required scalability, performance, and QoS features?

• A. Data Distribution Service (DDS)
• B. Safety Instrumented System (SIS)
• C. Information Sharing and Analysis Center (ISAC)
• D. Logistics (Industries and Sectors)

Answer: (A)

Data Distribution Service provides network interoperability and scalable, high-performance communication by using a publish-subscribe model with a rich set of QoS policies. These QoS options let you control reliability, durability, deadlines, latency budgets, liveliness, history, and resource limits, enabling predictable performance across many nodes and vendors. DDS also supports automatic discovery and a common data model, which helps disparate systems interoperate smoothly in large distributed environments. The other terms relate to different domains—Safety Instrumented Systems focus on safety control logic, ISACs are about information sharing for cybersecurity, and logistics pertains to supply chain functions—so they don’t address the need for interoperable, QoS-driven network communication.
