   Which IoT-related event could trigger a cascading failure in the power grid?

   • AA connected appliance in one home runs a cycle at the wrong time.
   • BA smart streetlight stays on all night.
   • CA single smart meter fails to report usage for one household.
   • DA malware infection spreads across many smart inverters, causing them to disconnect from the grid simultaneously.

   An airport's runway lighting system is controlled by IoT devices that can be remotely managed. A cyberattack disables the lighting system during a night landing. What is the most critical safety concern?

   • AThe airport will have to cancel all flights, causing passenger delays.
   • BThe airport will lose revenue from the cancelled flights.
   • CThe pilot may be unable to see the runway clearly, leading to a hard landing or runway excursion.
   • DThe airport's security cameras will also be disabled by the attack.

   How can an IoT failure cause an outage in critical infrastructure?

   • AA smart meter fails to report usage, so the utility sends a higher bill.
   • BA sensor in a water treatment plant fails, causing the system to shut down the entire plant.
   • CA smart streetlight stays on during the day.
   • DA connected thermostat in a home loses internet connectivity.

   An airline's maintenance system uses IoT sensors on aircraft engines to stream performance data to a ground-based analytics platform. The platform's vendor applies a firmware update that inadvertently disables the sensors' tamper-detection feature. A malicious actor exploits this to send false 'normal operation' data, masking a critical engine fault. The airline must decide on a mitigation. Which approach best addresses the root cause while minimizing operational disruption?

   • AIncrease the frequency of over-the-air firmware updates to ensure the tamper-detection feature is quickly restored.
   • BEncrypt all sensor data transmissions to prevent the attacker from sending false data.
   • CImplement a secondary, independent verification system that cross-checks engine sensor data against physical inspection reports before each flight.
   • DDisconnect all engine sensors from the network and rely solely on manual pilot inspections.

   Which IoT vulnerability could lead to contamination of a municipal water supply?

   • AA smart water meter in a home displays the wrong usage.
   • BA connected pump in a well runs longer than necessary.
   • CA smart faucet in a home leaks slightly.
   • DA sensor that monitors water pH fails and reports normal when the water is actually acidic.
