Google Professional Cloud Developer exam dumps: questions 401 to 480 of 480

Correct answers: A, C, E

• A. Correct.

  Using the Cloud SQL Auth proxy ensures secure and managed authentication to the database. It simplifies access by automatically handling IAM and encryption.

• B. Incorrect.

  While setting database credentials as environment variables is possible, it is not recommended as it may expose sensitive information without proper management tools like Secret Manager.

• C. Correct.

  Connection pooling is essential for efficient database connection management, especially in serverless environments like Cloud Run, where instances can scale rapidly.

• D. Incorrect.

  Allowing public IP access to the Cloud SQL instance may expose it to security risks and is not recommended unless absolutely necessary.

• E. Correct.

  Configuring the Cloud SQL instance to use private IP and connecting it to the same VPC as Cloud Run ensures secure and efficient network communication.

Correct answer: A

• A. Correct.

  Using a database connection pooler like Cloud SQL Auth Proxy is a recommended approach for managing connections efficiently in serverless environments such as Cloud Run. It helps reduce the number of concurrent connections to the database by pooling and reusing connections.

• B. Incorrect.

  While increasing the maximum connections of your Cloud SQL instance might temporarily alleviate the issue, it is not a scalable or cost-efficient solution. Long-term, managing connections effectively through pooling is better.

• C. Incorrect.

  Using a shared Cloud SQL user does not directly address the problem of connection management or pooling. It only standardizes access credentials across instances.

• D. Incorrect.

  Deploying a custom proxy service for connection pooling is unnecessary because Google Cloud provides native solutions like the Cloud SQL Auth Proxy, which are more secure and easier to manage.

Correct answer: A

• A. Correct.

  Cloud Bigtable is an ideal choice for real-time analytics and operational dashboard use cases as it is optimized for high-throughput, low-latency read and write operations. It is well-suited for storing large datasets like user activity logs.

• B. Incorrect.

  Cloud SQL is a relational database service that is better suited for structured data and transactional workloads rather than real-time analytics or storing vast amounts of activity data.

• C. Incorrect.

  Cloud Firestore is a NoSQL document database that is more suitable for applications requiring hierarchical or document-based data structures, not necessarily for large-scale real-time analytics.

• D. Incorrect.

  Cloud Storage is designed for storing unstructured data like files, images, and backups. It is not optimized for real-time analytics or frequent reads/writes of structured data.

Correct answers: A, D

• A. Correct.

  Correct. Cloud Firestore is a fully managed NoSQL database suited for structured data, and Cloud Storage is ideal for storing unstructured data like logs or files.

• B. Incorrect.

  Incorrect. While Cloud SQL is suitable for structured data, Cloud Pub/Sub is a messaging service and not a storage solution for unstructured data.

• C. Incorrect.

  Incorrect. Bigtable is a NoSQL database optimized for large analytical workloads, but it is not an ideal choice for typical structured data. Additionally, Cloud Logging is primarily used for log management, not directly for unstructured data storage.

• D. Correct.

  Correct. Cloud SQL is a managed relational database suitable for structured data, and Cloud Storage is ideal for storing unstructured data.

• E. Incorrect.

  Incorrect. BigQuery is optimized for analytical queries on large datasets but not for typical structured data storage. Cloud Spanner is a globally distributed relational database and not intended for unstructured data storage.

Correct answer: A

• A. Correct.

  Cloud Firestore is suitable for scalable, low-latency applications that require complex queries with multiple filters and sorting. It is a NoSQL database designed to handle real-time data synchronization and supports rich querying capabilities.

• B. Incorrect.

  Cloud SQL is a relational database that is better suited for applications requiring transactional consistency and SQL-based querying. However, it may not handle scalability and low-latency requirements as effectively as Cloud Firestore for NoSQL use cases.

• C. Incorrect.

  Cloud Spanner offers strong consistency and horizontal scalability, but it is better suited for global, relational database use cases rather than NoSQL applications with complex queries.

• D. Incorrect.

  Cloud Bigtable is optimized for analytical workloads and single-row key lookups but does not support complex querying with filters and sorting, making it less ideal for the given scenario.
