Google Cloud Professional Cloud Developer — Question 3

Your company wants to expand their users outside the United States for their popular application. The company wants to ensure 99.999% availability of the database for their application and also wants to minimize the read latency for their users across the globe.
Which two actions should they take? (Choose two.)

Answer options

• A. Create a multi-regional Cloud Spanner instance with "nam-asia-eur1" configuration.
• B. Create a multi-regional Cloud Spanner instance with "nam3" configuration.
• C. Create a cluster with at least 3 Spanner nodes.
• D. Create a cluster with at least 1 Spanner node.
• E. Create a minimum of two Cloud Spanner instances in separate regions with at least one node.
• F. Create a Cloud Dataflow pipeline to replicate data across different databases.

Correct answer: A, C

Explanation

Option A is correct as a multi-regional Cloud Spanner instance with the specified configuration ensures high availability and low latency for users in different regions. Option C is also correct because having at least 3 Spanner nodes in a cluster provides the necessary redundancy and performance needed to meet the availability requirement. The other options do not adequately address both the availability and latency needs of a global user base.
