   A test engineer is validating the integration of a new AUTOSAR SWC into an existing ECU. The SWC has a strict end-to-end latency requirement for a control loop. During integration testing, the engineer observes that the latency is higher than expected. Which of the following is the most likely cause related to the AUTOSAR architecture?

   • AThe RTE is configured with a scheduling scheme that delays the activation of the SWC's runnable entities.
   • BThe MCAL driver for the ADC is not optimized for the specific microcontroller.
   • CThe Service Layer's diagnostic module is interfering with the control loop.
   • DThe application SWC is directly accessing the CAN controller registers.

   An AUTOSAR development team is defining the architecture for a new vehicle dynamics controller. They need to specify how a 'VehicleSpeed' SWC will provide its output to a 'DashboardDisplay' SWC. The team wants to define the data flow at the architectural level before any code is generated. Which AUTOSAR concept should they use to formally define this connection?

   • ADefine a sender-receiver interface and connect the two components' ports with a connector in the VFB.
   • BDirectly write a function call in the application code of the DashboardDisplay SWC to read the VehicleSpeed SWC's global variable.
   • CUse a client-server interface where the DashboardDisplay SWC requests the speed value from the VehicleSpeed SWC.
   • DConfigure the CAN communication module to directly transmit the speed value to the DashboardDisplay SWC.

   An AUTOSAR project is moving from the system design phase to the ECU implementation phase. The system architect has defined the SWCs, their ports, and the VFB connections. The next step is to generate the RTE and the Basic Software configuration for a specific ECU. Which of the following is the correct next step in the AUTOSAR methodology?

   • ACreate a new system description that only contains the SWCs for this ECU, discarding the global system view.
   • BManually write the RTE code and the BSW configuration from scratch based on the system design documents.
   • CCompile the application SWCs directly against the hardware abstraction layer to create the ECU software.
   • DExtract the ECU-specific information from the system description and use it as input to the ECU configuration and RTE generation tools.

   In the AUTOSAR methodology, what is the typical outcome of the configuration and generation steps?

   • AA complete set of hardware schematics for the ECU.
   • BGenerated code for the RTE, Basic Software modules, and application components.
   • CA set of test cases for the system.
   • DA list of suppliers for the ECU components.
