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?



Answer : C

Scenario: The databases must be available if the SQL Server service fails.


Failover Clustering Overview

Windows Server Failover Clustering (WSFC) with SQL Server

Question 2

You have a server named Server1 that has 2 processors.

You plan to deploy multiple instances of SQL Server 2014 to Server1. Each instance will have multiple databases.

You need to recommend a method to allocate processor time to each database.

What should you include in the recommendation?

More than one answer choice may achieve the goal. Select the BEST answer.



Answer : A

SQL Server Resource Governor is a feature than you can use to manage SQL Server workload and system resource consumption. Resource Governor enables you to specify limits on the amount of CPU, physical IO, and memory that incoming application requests can use.


Incorrect:

D: PROCESS AFFINITY

Enables hardware threads to be associated with CPUs.

Question 3

You need to recommend changes to the ERP application to resolve the search issue. The solution must minimize the impact on other queries generated from the ERP application.

What should you recommend changing?

Question 4

You need to recommend a solution to allow application users to perform tables. The solution must meet the business requirements.

What should you recommend?



Answer : D

* 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.


Question 5

You have a server named Server1 that has 2 processors.

You plan to deploy multiple instances of SQL Server 2014 to Server1. Each instance will have multiple databases.

You need to recommend a method to set limits on processor time for each database.

What should you include in the recommendation?

More than one answer choice may achieve the goal. Select the BEST answer.



Answer : D

SQL Server Resource Governor is a feature than you can use to manage SQL Server workload and system resource consumption. Resource Governor enables you to specify limits on the amount of CPU, physical IO, and memory that incoming application requests can use.

Incorrect answers:

Not A: Processor affinity cannot be used to assign databases to processors.

Not B: The Microsoft SQL Server max degree of parallelism (MAXDOP) configuration option controls the number of processors that are used for the execution of a query in a parallel plan. It is not used limit the processor time for a database.

Not C: You can use Windows System Resource Manager to allocate processor and memory resources to applications, users, Remote Desktop Services sessions, and Internet Information Services (IIS) application pools. You cannot use Windows System Resource Manager to allocate resources for a database.

Question 6

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?



Answer : A

*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.

* 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.


Question 7

You need to recommend a solution to minimize the amount of time it takes to execute USP_5.

What should you include in the recommendation?



Answer : A

* Scenario: A stored procedure named USP_5 changes data in multiple databases. Security checks are performed each time USP_5 accesses a database.

* Cross-database ownership chaining occurs when a procedure in one database depends on objects in another database. A cross-database ownership chain works in the same way as ownership chaining within a single database, except that an unbroken ownership chain requires that all the object owners are mapped to the same login account. If the source object in the source database and the target objects in the target databases are owned by the same login account, SQL Server does not check permissions on the target objects.
