   What is the role of a port in AUTOSAR software component communication?

   • AIt defines the physical connector on the ECU that connects to the wiring harness.
   • BIt is a memory address used to store data within a software component.
   • CIt provides a point of interaction for a software component with other components or services through an interface.
   • DIt is a type of interface that defines the data elements exchanged between components.

   A test engineer is reviewing the architecture of an AUTOSAR-based ECU and needs to identify which module is responsible for providing a uniform interface to external EEPROM, regardless of whether the EEPROM is on the microcontroller's internal SPI bus or an external I2C bus. Which layer or module provides this abstraction?

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

   A team is designing an AUTOSAR system where a 'CruiseControl' SWC needs to request a 'SetSpeed' operation from a 'SpeedActuator' SWC. The operation takes a speed value as input and returns a status. Which AUTOSAR port and interface combination should be used to model this interaction?

   • AA server port on 'CruiseControl' and a client port on 'SpeedActuator', connected via a client-server interface.
   • BA client port on 'CruiseControl' and a server port on 'SpeedActuator', connected via a client-server interface.
   • CA single port on both components, connected via a mode-switch interface.
   • DA sender port on 'CruiseControl' and a receiver port on 'SpeedActuator', connected via a sender-receiver interface.

   What is the purpose of using templates in the AUTOSAR methodology?

   • ATo define the physical layout of the ECU hardware.
   • BTo provide a standardized format for describing system and software components, enabling tool-based configuration and code generation.
   • CTo provide a set of test cases for AUTOSAR software.
   • DTo replace the need for any configuration or code generation by providing ready-to-use software.
