Your company aims to monitor the presence of individuals in meeting rooms reserved for scheduled meetings across 1000 rooms in 5 offices on 3 continents. Each room has a motion sensor reporting its status every second, including a sensor ID and various discrete data points. Analysts will use this data alongside account owner and office location information. Which database type is most suitable for this scenario?

Real Exam

Explanation:

The correct answer is B (NoSQL) because solutions like Bigtable and Datastore are ideal for storing sensor IDs and various discrete data points. They also support data joining with other sources. Datastore can be configured for multi-region data storage.

  • Option A (Flat file) is incorrect due to scalability issues.
  • Option C (Relational database) is not suitable for schema-less data.
  • Option D (Blob storage) is inappropriate for storing, analyzing schema-less data, and joining with other sources.

Refer to GCP documentation for more details on Storage Options.
