Correct Answer: C
Explanation/Reference:
Explanation:
SQL Server has alerts that get more important based on the severity of the alert. Anything of severity 16 or below tends to refer to the database and deals with issues that are tied to syntax errors, violations of foreign keys, etc. While those errors are typically important, they don’t refer to anything with regards to overall health of the SQL Server. Alerts 17 through 25 do. Those are the ones your health checks are probably firing on.
