QUESTION 1
You administer a Microsoft SQL Server 2012 database that has multiple tables in the Sales schema.
Some users must be prevented from deleting records in any of the tables in the Sales schema.
You need to manage users who are prevented from deleting records in the Sales schema. You need to achieve this goal by using the minimum amount of administrative effort.
What should you do?

A. Create a custom database role that includes the users. Deny Delete permissions on the Sales schema for the custom database role.
B. Include the Sales schema as an owned schema for the db_denydatawriter role. Add the users to the db_denydatawriter role.
C. Deny Delete permissions on each table in the Sales schema for each user.
D. Create a custom database role that includes the users. Deny Delete permissions on each table in the Sales schema for the custom database role.

Answer: A


QUESTION 2
You administer a Microsoft SQL Server 2012 failover cluster that contains two nodes named Node A and Node B. A single instance of SQL Server is installed on the cluster.
An additional node named Node C has been added to the existing cluster.
You need to ensure that the SQL Server instance can use all nodes of the cluster.
What should you do?

A. Run the New SQL Server stand-alone installation Wizard on Node C.
B. Run the Add Node to SQL Server Failover Cluster Wizard on Node C.
C. Use Node B to install SQL Server on Node C.
D. Use Node A to install SQL Server on Node C.

Answer: B

Explanation:
http://technet.microsoft.com/en-us/library/ms191545.aspx
To add a node to an existing SQL Server failover cluster, you must run SQL Server Setup on the node that is to be added to the SQL Server failover cluster instance. Do not run Setup on the active node.
The Installation Wizard will launch the SQL Server Installation Center. To add a node to an existing failover cluster instance, click Installation in the left-hand pane. Then, select Add node to a SQL Server failover cluster.


QUESTION 3
You administer a Microsoft SQL Server 2012 database named ContosoDB. The database contains a table named Suppliers and a column named IsActive in the Purchases schemA.
You create a new user named ContosoUser in ContosoDB. ContosoUser has no permissions to the Suppliers table.
You need to ensure that ContosoUser can delete rows that are not active from Suppliers. You also need to grant ContosoUser only the minimum required permissions.
Which Transact-SQL statement should you use?

A. GRANT DELETE ON Purchases. Suppliers TC ContosoUser

B. CREATE PROCEDURE Purchases.PurgelnactiveSuppliers WITH EXECUTE AS USER = 'dbo'
AS
DELETE FROM Purchases.Suppliers WHERE IsActive = 0
GO
GRANT EXECUTE ON Purchases.PurgelnactiveSuppliers TO ContosoUser

C. GRANT SELECT ON Purchases.Suppliers TO ContosoUser

D. CREATE PROCEDURE Purchases. PurgeInactiveSuppliers AS
DELETE FROM Purchases.Suppliers WHERE IsActive = 0
GO
GRANT EXECUTE ON Purchases. PurgeInactiveSuppliers TO ContosoUser
