   A logistics company is building a predictive maintenance model for its fleet of vehicles. The data is collected from IoT sensors on the vehicles and is streamed to a central data platform. The data science team has noticed that the sensor data contains many duplicate readings and some readings with impossible values (e.g., negative speed). Before training the model, which data preparation step is most critical?

   • APerform data normalization to scale the sensor values to a standard range.
   • BPerform feature engineering to create new features from the raw sensor data.
   • CPerform data cleansing to remove duplicates and correct or remove out-of-range values.
   • DPerform data augmentation to increase the size of the dataset.

   A government agency is deploying an AI system to analyze satellite imagery for disaster response. The data is highly sensitive and must be protected both when stored and when transmitted to the model for inference. The agency's security team has mandated that all data at rest be encrypted and that data in transit be protected. Which security control set fully satisfies the mandate?

   • AUse AES-256 encryption for the data at rest in the storage account, and use TLS 1.2 or higher for all data transfers between the storage and the inference service.
   • BUse a VPN for all data transfers and rely on the storage provider's default encryption for data at rest.
   • CApply data masking to the satellite images before storing them, and use HTTPS for data transfers.
   • DStore the data in an on-premises air-gapped server and transfer it to the inference service via a USB drive.
