The app requires a database capable of providing high-speed, global data storage for a large volume of unstructured data, such as sensor logs and images.Which of the following Google Cloud services is most suitable for the data storage requirements of the GlobalSensorNet app?Options:A) Google BigQueryB) Cloud StorageC) Cloud SQLD) Cloud SpannerCorrect Answer: B) Cloud StorageExplanation:Option A: Google BigQuery (Incorrect)Explanation: Google BigQuery is a fully-managed, serverless data warehouse designed for large-scale data analytics and querying. While it is excellent for storing and analyzing structured data, it is not optimized for high-speed, global data storage of unstructured data such as sensor logs and images. BigQuery is more suited for querying large datasets rather than being used as a primary storage solution for unstructured data. Therefore, BigQuery is not the best option for this use case.Option B: Cloud Storage (Correct)Explanation: Google Cloud Storage is the most suitable solution for storing large volumes of unstructured data like images, sensor logs, videos, and backups. It is highly scalable, globally distributed, and designed for durability, providing high-speed access to stored data. Since the app needs to handle large amounts of unstructured data across the globe, Cloud Storage is the right choice due to its flexibility, scalability, and support for various storage classes (e.g., Nearline, Coldline, etc.). It allows for easy storage and retrieval of files, which is crucial for the "GlobalSensorNet" app's data storage needs.Option C: Cloud SQL (Incorrect)Explanation: Cloud SQL is a fully-managed relational database service for SQL-based databases like MySQL, PostgreSQL, and SQL Server. While it is great for structured data with relational needs, Cloud SQL is not ideal for storing large volumes of unstructured data like sensor logs and images. Relational databases are generally not designed to efficiently handle such data types, and they can become expensive and less performant when scaling for large datasets, especially with high-speed storage requirements.Option D: Cloud Spanner (Incorrect)Explanation: Cloud Spanner is a globally distributed relational database service that provides strong consistency and scalability for transactional data. While it is a powerful choice for applications requiring high availability and relational data management at scale, it is not the best fit for unstructured data like sensor logs and images. Cloud Spanner is designed for structured data that requires transactions and relational integrity, so it is not optimized for large volumes of unstructured data like Cloud Storage is.Get started today and ensure you are fully prepared for your Google Cloud Digital Leader exam!
