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.

You need to recommend a database reporting solution that meets the business
What should you include in the recommendation?

  • A. Data collection
  • B. Performance Monitor
  • C. A maintenance plan
  • D. A dynamic management view

Answer : A

Explanation: * Scenario: System administrators must be able to run real-time reports on disk usage. * The data collector provides an historical report for each of the System Data collection sets. Each of the following reports use data that is stored in the management data warehouse: Disk Usage Summary Query Statistics History Server Activity History You can use these reports to obtain information for monitoring system capacity and troubleshooting system performance. Reference: System Data Collection Set Reports

Question No : 3 - Topic 1

During performance testing, you discover that database INSERT operations against the
Inventory table are slow.
You need to recommend a solution to reduce the amount of time it takes to complete the
INSERT operations.
What should you recommend?

  • A. Partition the nonclustered index.
  • B. Partition the Inventory table.snapshot replication
  • C. Create a column store index.Master Data Services
  • D. Drop the clustered index.change data capture

Answer : A

Explanation: Scenario: Database2 will contain a table named Inventory. Inventory will contain over 100 GB of data. The Inventory table will have two indexes: a clustered index on the primary key and a nonclustered index. The column that is used as the primary key will use the identity property.

Question No : 4 - Topic 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 No : 5 - Topic 1

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)
