Answer to Question 1

FALSE

Answer to Question 2

The Transact-SQL IDENTITY_INSERT property allows users to control whether or not the IDENTITY constraint is in effect. To insert non-sequential data, we (1 ) use the command SET IDENTITY_INSERT tableName OFF to disable the IDENTITY constraint, (2 ) insert the non-sequential data, and (3 ) use the command SET IDENTITY_INSERT TableName ON to enable the IDENTITY constraint again.
