The question asks for two best practice recommendations for loading data into Snowflake. Option C is correct because Snowflake recommends loading files that are 100-250 MB or larger for optimal performance, as smaller files can lead to inefficiencies in parallel processing. Option D is correct because avoiding embedded characters like commas in numeric data types prevents parsing issues during data loading, especially with delimited text files. Option A is incorrect as it recommends loading very small files (25 MB or smaller), which contradicts Snowflake's best practices. Option B is incorrect because removing all dates and timestamps is not a general best practice; it depends on the data requirements. Option E is incorrect because semi-structured data types (e.g., JSON, Avro) are natively supported in Snowflake and do not need to be removed.
