A manufacturing plant installs vibration sensors on conveyor motors. Each sensor publishes a reading every 200 ms, and the plant's network team wants to minimize bandwidth usage while ensuring the data is delivered reliably even if the network briefly drops. The data engineering team plans to process the readings in near real time to detect anomalies. Which combination of ingestion protocol and processing pattern best meets these requirements?

HTTP POST requests to a REST API, then batch processing every hour

AMQP with a message broker, then batch processing at the end of each shift

MQTT over TCP with a broker, then stream processing on the incoming topic

Raw TCP sockets with custom framing, then stream processing on the raw stream

A smart-building company collects occupancy and energy usage data from sensors in office buildings. The data is transmitted over the internet to a cloud data platform. The company must comply with privacy regulations that require personal data to be protected. Which set of measures is most appropriate?

Encrypt data in transit and at rest, and implement role-based access control

Anonymize all data before transmission and store it in a public cloud

Use a public cloud without additional security measures because the cloud provider is responsible for security

Use a private network for all data transmission and store data on-premises only
