Answer: ENABLE_QUERY_ACCELERATION = TRUE

The question asks for a setting that prevents both over-provisioning and auto-scaling during increased concurrency. Option D (ENABLE_QUERY_ACCELERATION = TRUE) is correct because it dynamically allocates resources for specific queries without requiring manual scaling or fixed cluster expansion, thus avoiding over-provisioning and auto-scaling. Option C (MAX_CLUSTER_COUNT = 10) is incorrect as it enables auto-scaling up to 10 clusters, contradicting the requirement to avoid auto-scaling. Option A (WAREHOUSE_SIZE = LARGE) leads to over-provisioning by allocating large fixed resources. Option B (WAREHOUSE_TYPE = SNOWPARK-OPTIMIZED) is optimized for Snowpark workloads but doesn't inherently prevent auto-scaling or over-provisioning. The community discussion supports D, with upvoted comments highlighting its dynamic resource allocation without scaling clusters.
