QUESTION 1
You need to recommend a solution for the deployment of SQL Server 2014. The solution must meet the business requirements.
What should you include in the recommendation?

A. Create a new instance of SQL Server 2014 on the server that hosts the SQL Server 2008 instance.
B. Upgrade the existing SQL Server 2008 instance to SQL Server 2014.
C. Deploy two servers that have SQL Server 2014 installed and implement Failover Clustering.
D. Deploy two servers that have SQL Server 2014 installed and implement database mirroring.

Answer: C

Explanation:
Scenario: The databases must be available if the SQL Server service fails.
Reference:
Failover Clustering Overview
Windows Server Failover Clustering (WSFC) with SQL Server


QUESTION 2
You need to recommend a solution to allow application users to perform tables. The solution must meet the business requirements.
What should you recommend?

A. Create a Policy-Based Management Policy.
B. Create a user-defined database role and add users to the role.
C. Create stored procedures that use EXECUTE AS clauses.
D. Create functions that use EXECUTE AS clauses.

Answer: D

Explanation:
* c Clause (Transact-SQL)
In SQL Server you can define the execution context of the following user-defined modules: functions (except inline table-valued functions), procedures, queues, and triggers.
Reference: Using EXECUTE AS in Modules


QUESTION 3
You need to recommend a feature to support your backup solution.
What should you include in the recommendation?

A. Transparent Data Encryption (TDE)
B. Column-level encryption
C. An NTFS file permission
D. A Secure Sockets Layer (SSL)

Answer: A

Explanation:
* Scenario: You must encrypt the backup files to meet regulatory compliance requirements. The encryption strategy must minimize changes to the databases and to the applications.
* Transparent data encryption (TDE) performs real-time I/O encryption and decryption of the data and log files. The encryption uses a database encryption key (DEK), which is stored in the database boot record for availability during recovery.
Reference: Transparent Data Encryption (TDE)


QUESTION 4
You need to recommend a solution to synchronize Database2 to App1_Db1.
What should you recommend?

A. Change data capture
B. Snapshot replication
C. Master Data Services
D. Transactional replication

Answer: D

Explanation:
Scenario:
* Data from Database2 will be accessed periodically by an external application named Application1. The data from Database2 will be sent to a database named App1_Db1 as soon as changes occur to the data in Database2.
* All data in Database2 is recreated each day and does not change until the next data creation process.
Reference:
Transactional Replication


QUESTION 5
You need to recommend a solution to improve the performance of usp.UpdateInventory. The solution must minimize the amount of development effort.
What should you include in the recommendation?

A. A table variable
B. A common table expression
C. A subquery
D. A cursor

Answer: A

Explanation:
*Scenario: Database2 will contain a stored procedure named usp_UpdateInventory. Usp_UpdateInventory will manipulate a table that contains a self-join that has an unlimited number of hierarchies.
* A table variable can be very useful to store temporary data and return the data in the table format.
table
* Example: The following example uses a self-join to find the products that are supplied by more than one vendor.
Because this query involves a join of the ProductVendor table with itself, the ProductVendor table appears in two roles. To distinguish these roles, you must give the ProductVendor table two different aliases (pv1 and pv2) in the FROM clause. These aliases are used to qualify the column names in the rest of the query. This is an example of the self-join Transact-SQL statement:
USE AdventureWorks2008R2; GO
SELECT DISTINCT pv1.ProductID, pv1.VendorID FROM Purchasing.ProductVendor pv1
INNER JOIN Purchasing.ProductVendor pv2
ON pv1.ProductID = pv2.ProductID
AND pv1.VendorID <> pv2.VendorID
ORDER BY pv1.ProductID
Incorrect:
Not B: Using a CTE offers the advantages of improved readability and ease in maintenance of complex queries. The query can be divided into separate, simple, logical building blocks. These simple blocks can then be used to build more complex, interim CTEs until the final result set is generated.
