Google Professional Cloud Database Engineer Question 92
Select 4Google Cloud PlatformYour team is migrating a traditional on-premises application to Google Cloud. The application relies on a MySQL database, which in turn depends on a caching layer and a message queue for asynchronous processing. To ensure a smooth migration, you need to assess the application and database dependencies. Which steps should you take as part of this dependency assessment?
- A
Identify all upstream and downstream systems interacting with the database.
- B
Analyze database query patterns to determine performance requirements.
- C
Review IAM permissions to ensure proper access control for the database in Google Cloud.
- D
Map the application’s caching layer to a suitable Google Cloud product like Memorystore.
- E
Evaluate the network latency between the application and the database post-migration.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Assessing application and database dependencies is a critical step in preparing for a migration. It involves identifying all systems that interact with the database, understanding workload and performance requirements, addressing key components like caching, and ensuring network considerations are accounted for. Security considerations like IAM permissions, while important, fall outside the specific scope of dependency assessment.
- A. Correct.
Correct: Identifying all systems interacting with the database ensures you don’t overlook any critical dependencies during migration.
- B. Correct.
Correct: Understanding query patterns helps ensure the target database in Google Cloud can meet performance and workload requirements.
- C. Incorrect.
Incorrect: While reviewing IAM permissions is a necessary step for securing the database, it is not part of assessing the application and database dependencies specifically.
- D. Correct.
Correct: Ensuring the caching layer is mapped to a compatible Google Cloud product is key to maintaining application performance and dependency mapping.
- E. Correct.
Correct: Evaluating network latency is essential to ensure that the application and database performance remain optimal post-migration.
