Google Professional Cloud Database Engineer Question 91
Select 3Google Cloud PlatformYou are tasked with migrating an on-premises application to Google Cloud. The application uses a relational database hosted on a local server. Before beginning the migration, you need to assess the application and database dependencies to ensure a seamless transition. Which steps should you take to identify the dependencies effectively?
- A
Analyze the application code to identify database connection strings and queries.
- B
Review the database schema for stored procedures, triggers, and dependencies.
- C
Focus solely on the database schema without analyzing the application code.
- D
Identify external systems or APIs that interact with the database or application.
- E
Perform a load test to estimate the database's current performance baseline.
Show answer and explanation
Correct answers: A, B, D
Explanation
Assessing application and database dependencies involves understanding how the application interacts with the database, identifying internal database components, and accounting for all external integrations. Focusing only on one aspect or unrelated tasks, like load testing, does not provide a complete picture.
- A. Correct.
Analyzing the application code helps identify how the application interacts with the database, such as connection strings and SQL queries, which are critical for understanding dependencies.
- B. Correct.
Reviewing the database schema is essential to identify any internal dependencies like stored procedures, triggers, or foreign key relationships.
- C. Incorrect.
Focusing solely on the database schema ignores the application-level dependencies, which can lead to incomplete migration planning.
- D. Correct.
Identifying external systems or APIs ensures that all integrations with the application and database are accounted for during migration.
- E. Incorrect.
While load testing is useful for performance benchmarking, it does not directly help in identifying application and database dependencies.
