Which of the following is the correct region code for US West (Oregon) in Snowflake on AWS?

• A. us-east-2
• B. ca-central-1
• C. us-west-2
• D. sa-east-1

Answer: (C)

The region code for US West (Oregon) when using Snowflake on AWS is us-west-2. Snowflake on AWS uses the same AWS region identifiers, so selecting us-west-2 targets the Oregon data center. The other codes map to different locations: us-east-2 is US East (Ohio), ca-central-1 is Canada Central, and sa-east-1 is São Paulo. Choosing the correct region matters for latency, data residency, and which AWS/Snowflake resources are available in that region.
