GCP - Cloud SQL and Databases

Given this Cloud Spanner instance configuration:

instance_config = "nam3"
nodes = 3

What is the expected behavior of this setup?

AData is globally distributed across North America with 3 nodes handling requests.

BData is stored in a single region with 3 nodes for processing.

CData is stored only in Europe with 3 nodes.

DData is stored in Asia with 3 nodes but no replication.

Step-by-Step Solution

Solution:

Step 1: Interpret instance_config "nam3"
"nam3" is a multi-region config for North America, so data is distributed across multiple regions there.
Step 2: Understand nodes setting
3 nodes means the instance has 3 processing units to handle workload.
Final Answer:
Data is globally distributed across North America with 3 nodes handling requests. -> Option A
Quick Check:
nam3 = North America multi-region + 3 nodes [OK]

Quick Trick: Multi-region config + nodes = distributed data with processing power [OK]
