Middleware in real-time systems helps to: (A) Abstract communication details and enable interoperability across heterogeneous systems (B) CPU idle exclusively (C) Disk batch-only data transfer (D) Memory-only processing 3. A key requirement for real-time middleware is: (A) Support for predictable timing and bounded latency (B) CPU idle exclusively (C) Disk batch-only tasks (D) Memory-only operations 4. Examples of real-time middleware include: (A) CPU idle exclusively (B) RT CORBA, DDS (Data Distribution Service), and OPC UA (C) Disk batch-only libraries (D) Memory-only frameworks 5. Data Distribution Service (DDS) middleware is used for: (A) Memory-only storage (B) CPU idle exclusively (C) Disk batch-only messaging (D) Publish-subscribe communication with real-time guarantees 6. Real-time CORBA middleware provides: (A) Deterministic remote procedure calls (RPCs) and scheduling control (B) CPU idle exclusively (C) Disk batch-only RPC (D) Memory-only operations 7. Middleware can help real-time systems by: (A) Disk batch-only tasks (B) CPU idle exclusively (C) Managing task coordination, resource access, and communication transparently (D) Memory-only operations 8. QoS (Quality of Service) parameters in real-time middleware include: (A) Disk batch-only parameters (B) CPU idle exclusively (C) Latency, throughput, priority, and reliability (D) Memory-only metrics 9. Real-time middleware supports which type of task communication? (A) Disk batch-only communication (B) CPU idle exclusively (C) Both time-triggered and event-triggered interactions (D) Memory-only messaging 10. Middleware can reduce the complexity of distributed real-time systems by: (A) CPU idle exclusively (B) Handling communication, synchronization, and resource management automatically (C) Disk batch-only tasks (D) Memory-only operations 11. Publish-subscribe models in middleware are advantageous because: (A) Producers and consumers are decoupled in time and space (B) CPU idle exclusively (C) Disk batch-only decoupling (D) Memory-only coupling 12. Middleware ensures temporal predictability in real-time systems by: (A) Disk batch-only guarantees (B) CPU idle exclusively (C) Providing bounded latency and priority-aware communication mechanisms (D) Memory-only timing 13. Resource management in middleware allows: (A) Fair and predictable access to shared system resources among tasks (B) CPU idle exclusively (C) Disk batch-only allocation (D) Memory-only scheduling 14. Fault tolerance in real-time middleware can be achieved by: (A) Memory-only recovery (B) CPU idle exclusively (C) Disk batch-only fault handling (D) Redundant communication paths, replication, and error detection mechanisms 15. Middleware can support heterogeneous real-time systems by: (A) Memory-only adaptation (B) CPU idle exclusively (C) Disk batch-only abstraction (D) Abstracting differences in hardware, OS, and network protocols 16. Real-time middleware typically provides: (A) CPU idle exclusively (B) APIs for communication, synchronization, and scheduling control (C) Disk batch-only services (D) Memory-only APIs 17. Middleware in safety-critical systems must comply with: (A) Disk batch-only standards (B) CPU idle exclusively (C) Standards such as ARINC 653, ISO 26262, or DO-178C (D) Memory-only guidelines 18.
