A smart agriculture company collects soil moisture readings from 10,000 sensors every minute. They need to store historical data for trend analysis and also run real-time alerts when moisture drops below a threshold. Which cloud storage and processing combination best meets these needs?

Edge storage only and no cloud processing

Relational database for all data and periodic SQL queries for alerts

Time-series database for all data and a stream processing service for alerts

Object storage for all data and batch analytics for alerts

A weather monitoring network generates 1 TB of raw sensor data per day. The team needs to run complex queries on this data for research, but only a small subset is accessed frequently. Which storage solution is most appropriate?

Local file storage on each sensor

Relational database with all data

Time-series database for all data

Object storage with a data lake and query engine

A company is choosing between AWS IoT Core, Azure IoT Hub, and Google Cloud IoT Core for a new IoT product. The product requires device management, secure connectivity, and integration with machine learning services. The team has experience with multiple cloud providers. Which factor is most important in the selection decision?

The provider's logo and brand recognition

The number of available IoT protocols supported

The provider's integration with the team's existing ML and analytics tools

The provider's data center location only

A smart city project collects traffic data from 10,000 sensors. The data is used for real-time traffic management and long-term urban planning. The budget is limited, and the data volume is large. The city wants to minimize cloud costs while maintaining real-time performance. Which strategy is most cost-effective?

Send all raw data to the cloud and store it in a time-series database

Use edge computing to filter and aggregate data before sending only relevant events to the cloud

Store all data in object storage and query it directly for real-time management

Use a large cloud instance to process all data in real time

Which security practice is essential to protect IoT data transmitted between devices and the cloud?

Using encryption protocols such as TLS

Using only HTTP for communication

Storing all data in plaintext for easier access

Disabling device authentication to reduce overhead
