   A supplier is integrating a new brake-by-wire application onto an AUTOSAR-based ECU. The application software component (SWC) must send a pedal-position value to a second SWC on the same ECU, and both components must remain unaware of the physical memory addresses or bus protocols involved. Which AUTOSAR element is responsible for decoupling these components and carrying the data between them?

   • AThe Runtime Environment (RTE)
   • BThe Microcontroller Abstraction Layer (MCAL)
   • CThe Service Layer
   • DThe ECU Abstraction Layer (ECU Abstraction)

   A test team is analyzing a failure in an AUTOSAR-based engine control unit. The failure is traced to a driver that directly interacts with the microcontroller's internal ADC registers to read a sensor value. According to the AUTOSAR layered architecture, which layer should contain this driver?

   • AService Layer
   • BApplication Layer
   • CMicrocontroller Abstraction Layer (MCAL)
   • DECU Abstraction Layer

   An OEM is comparing AUTOSAR Classic and AUTOSAR Adaptive for a new autonomous driving domain controller. The platform needs to support high-performance computing, dynamic service discovery, and over-the-air (OTA) updates. Which of the following is the most appropriate choice and reasoning?

   • AAUTOSAR Classic, because it is better suited for high-performance computing.
   • BEither standard can be used, as they are interchangeable.
   • CAUTOSAR Classic, because it is the only standard that supports OTA updates.
   • DAUTOSAR Adaptive, because it is designed for high-performance computing and supports dynamic service discovery and OTA updates.

   How does the RTE enable communication between software components in AUTOSAR?

   • ABy requiring all components to be compiled into a single monolithic binary.
   • BBy using a shared global memory area that all components can access directly.
   • CBy providing generated code that implements the communication based on the component interfaces and connectors.
   • DBy directly connecting the components' ports via physical wires.
