   During integration testing of an AUTOSAR ECU, a test engineer finds that a sensor value is occasionally read as '0' by an application SWC, even though the sensor is functioning correctly. The SWC uses a sender-receiver port with a data element of type uint16. The RTE is configured for implicit communication. What is the most likely cause of this intermittent zero value?

   • AThe MCAL driver for the sensor is reading the value incorrectly.
   • BThe application SWC is using a client-server interface instead of a sender-receiver interface.
   • CThe RTE is using an uninitialized buffer for the receiver port, and the sender has not yet written a valid value.
   • DThe Service Layer's communication stack is dropping the CAN frames.

   A test team is performing configuration testing on a new AUTOSAR ECU. They have verified that the application SWCs are correctly integrated. However, a diagnostic service is not responding correctly to a tester request. The diagnostic service is part of the Basic Software. Which of the following is the most likely cause of this failure?

   • AThe RTE is not correctly scheduling the diagnostic service's runnable entities.
   • BThe application SWC is not correctly implementing the diagnostic interface.
   • CThe MCAL driver for the CAN controller is not optimized for the specific microcontroller.
   • DThe Diagnostic Service Layer is not correctly configured with the appropriate Diagnostic Event Manager (DEM) and Diagnostic Communication Manager (DCM) parameters.

   An automotive OEM is evaluating AUTOSAR for its next-generation vehicle platform. The primary motivation is to reduce development costs and time-to-market by reusing software across multiple vehicle models and suppliers. Which of the following AUTOSAR goals directly supports this objective?

   • AEliminating the need for hardware abstraction by allowing SWCs to directly access all microcontroller peripherals.
   • BMandating the use of a single, proprietary operating system for all ECUs.
   • CRequiring all application software to be developed by the OEM and not by suppliers.
   • DStandardization of the software architecture and interfaces to enable the exchange and reuse of SWCs between different ECUs and suppliers.
