Question 3: Which SQL query optimization technique is most effective when querying large datasets in a time-series database for environmental data?

Which action should you take?

Choose only one option

Using subqueries to break down large queries

Using a join over multiple tables for aggregation

Reducing the number of columns returned in SELECT queries

Using appropriate indexing strategies

Question 4: What is the most effective data integration strategy when combining real-time environmental data from remote sensors and historical data from a central database?

Which action should you take?

Choose only one option

Real-time data aggregation with data normalization

Using micro-batching techniques

Streaming data pipeline with batch processing

Integrating with a data warehouse

Question 5: How would you ensure that an environmental IT system maintains optimal performance as it scales to handle millions of real-time sensor inputs?

Which action should you take?

Choose only one option

By focusing only on horizontal scaling without optimizing software

By using a single server and adding more memory or CPU as needed

By relying on a monolithic architecture without scalability in mind

By implementing a distributed architecture with microservices, containerization, and auto-scaling cloud services

Question 6: How would you address data security challenges when integrating sensitive environmental health data from multiple sources into a central system?

Which action should you take?

Choose only one option

By focusing only on secure network protocols without securing the data itself

By implementing encryption, access control policies, and audit logging to ensure data security and privacy

By using unencrypted data and relying on user trust for security
