Top 10 AUTOSAR MCQ Practice Test – Set 13 Set 13 Focusing on AUTOSAR Communication Protocols (CAN, LIN, FlexRay, Ethernet) 1 / 10 Why is Ethernet becoming more important in AUTOSAR Adaptive? To handle over-the-air updates, ADAS communication, and service-oriented architecture To reduce brake system cost To replace mechanical steering To control airbags 2 / 10 In a CAN network, message identifiers (IDs) are also used as: Message priority (lower ID = higher priority) ECU memory address Password for communication Hardware serial number 3 / 10 Which UDS communication layer is used when running diagnostics over IP (DoIP)? FlexRay LIN Ethernet SPI 4 / 10 Transport Protocol (CAN TP / FlexRay TP / DoIP) in AUTOSAR is used to: Encrypt messages Handle long messages larger than one frame Control OS scheduling Reset watchdog 5 / 10 In AUTOSAR, PDU Router (PduR) is responsible for: Routing PDUs between communication modules (e.g., CAN, FlexRay, COM) ECU power states Safety fallback control Memory partitioning 6 / 10 Which AUTOSAR module maps application-level signals into CAN messages or PDUs? DEM NVRAM RTE COM 7 / 10 Automotive Ethernet is preferred for: Cloud services only Replacing tire sensors High data-rate needs like ADAS cameras, radar, infotainment Only diagnostics 8 / 10 FlexRay protocol is mainly used in: Safety-critical and high-speed applications (e.g., chassis, x-by-wire) Tire Pressure Monitoring Systems Audio systems in car Sunroof controls 9 / 10 LIN protocol in AUTOSAR is mainly used for: High-speed powertrain communication Low-cost, low-speed body electronics (e.g., window, mirrors) Internet connectivity Infotainment streaming 10 / 10 Which is the most widely used communication protocol in AUTOSAR Classic ECUs?
