Answer: 192

The correct answer is D (192 credits). A 3X-Large warehouse consumes 64 credits per cluster per hour. For the first hour with one cluster: 64 credits. For the second hour with two clusters: 2 × 64 = 128 credits. Total: 64 + 128 = 192 credits. This aligns with Snowflake's documented credit usage for multi-cluster warehouses and is supported by the community discussion, where all comments (with upvotes ranging from 2 to 4) unanimously select D, citing calculations (e.g., 64 + 128) and references to official documentation. Options A (64), B (128), and C (149) are incorrect as they undercount the total or lack divisibility by 64, which is the hourly rate for a 3X-Large cluster.
