You administer a Microsoft SQL Server 2012 database. Users report that a billing application becomes unresponsive during busy times of the day. While investigating, you notice large number of processes taking or waiting for table locks. You suspect that SQL Server is assigning stronger locks to queries.
You start a SQL Profiler trace. Which event should you select?
You administer a Microsoft SQL Server environment. You purchase a new server and plan to migrate your database from SQL Server 2008 to SQL Server 2012. You want to evaluate to prepare for possible conflicts and issues that may arise during or after the migration. Which SQL Server tool should you use?
Your database contains a table named SalesOrders. The table includes a DATETIME column named OrderTime that stores the date and time each order is placed. There is a non-clustered index on the OrderTime column. The business team wants a report that displays the total number of orders placed on the current day. You need to write a query that will return the correct results in the most efficient manner. Which Transact-SQL query should you use?
SELECT COUNT(*) FROM SalesOrders
WHERE OrderTime = CONVERT(DATE, GETDATE())
SELECT COUNT(*) FROM SalesOrders WHERE OrderTime = GETDATE()
SELECT COUNT(*) FROM SalesOrders
WHERE CONVERT(VARCHAR, OrderTime, 112) = CONVERT(VARCHAR, GETDATE(I, 112))
SELECT COUNT(*) FROM SalesOrders
WHERE OrderTime >= CONVERT(DATE, GETDATE())
AND OrderTime < DATEADD(DAY, CONVERT(DATE, GETDATE()))
You are a database administrator for a Microsoft SQL Server 2012 instance. You need to ensure that data can be migrated from a production server to two reporting servers with minimal data to ensure that data on the reporting server is always accessible which solution should you use?
Change Data Capture
QUESTION: 240 DRAG DROP
You are a database administrator for a Microsoft SQL Server 2012 environment that contains two SQL Server instances named Server01 and Server02. The Contoso database is located on Server01. Through database mirroring, a copy of the Contoso database is on Server02. During the last manual failover of database mirroring, the recovery took longer than usual. You need to determine where the synchronization bottleneck is for the database mirroring topology. Which performance counter or counters should you use for each server? (To answer, drag the appropriate performance counter or counters to their corresponding server or servers in the answer area. Answer choices may be used once, more than once, or not at all. Answer targets may be used once or not at all. Additionally, you may need to drag the split bar between panes or scroll to view content.)
Which of the following statements will set the maximum amount of system memory that is managed by the SQL Server Memory Manager to 4GB?
You administer a Microsoft SQL Server 2012 instance. An application executes a large volume of dynamic queries. You need to reduce the amount of memory used for cached query plans. What should you do? (To answer, move the appropriate statements from the list of statements to the answer area and arrange them in the correct order.)
SQL SERVER – 2008 – Optimize for Ad hoc Workloads – Advance Performance Optimization
Every batch (T-SQL, SP etc) when ran creates execution plan which is stored in system for re-use. Due to this reason a large number of query plans are stored in system. However, there are plenty of plans which are only used once and have never re-used again. One time ran batch plans wastes memory and resources.
Let us now enable the option of optimizing ad hoc workload. This feature is available in all the versions of SQL Server 2008.
sp_CONFIGURE 'show advanced options',1 RECONFIGURE GO
sp_CONFIGURE ‘optimize for ad hoc workloads’,1 RECONFIGURE GO
SQL Server 2008 has feature of optimizing ad hoc workloads.
Which of the following files keeps track of all transactions that occur in an SQL
You have a SQL Server database named DB1. You plan to load 10 milion rows to DB1 by running bcp.exe. You need to modify DB1 to minimize the amount of space required to store the transaction logs during the load operation. The solution must ensure that you can perform a point-in- time restore. Which database setting should you modify?
Compatibility level to 120
Containment type to partial.
Recovery model to Bulk logged.
Recovery model to simple.
You administer a Microsoft SQL Server 2012 database. The database contains a customer table created by using the following definition:
You need to ensure that the minimum amount of disk space is used to store the data in the customer table. What should you do?
Implement row-level compression.
Implement page-level compression.
Convert all indexes to Column Store indexes.
Implement Unicode compression.
QUESTION: 246 HOTSPOT
You administer a Microsoft SQL Server 2012 database instance. Other applications run on the server. Some of the applications are throwing errors because of insufficient memory. You need to ensure that the other applications have sufficient memory. Which setting should you configure?
You are the administrator of a Microsoft SQL Server 2012 server. Some applications consume significant resources. You need to manage the server workload by restricting resource-intensive applications You need to dynamically limit resource consumption. What should you do?
Configure Resource Pools, Workload Groups, and Classifier Function, and then enable the Resource Governor
Set up Service Broker to ensure that application are not allowed to consume more than the specified amount of resource
Create a new rule for each application that sets the resource limit allowed
Create a new plan Guide with a Scope Type of sql and define the resource limits for each application
