QUESTION NO: 1
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview,
Product, and SalesPerson. The tables were created using the following Transact SQL statements:
You must modify the ProductReview Table to meet the following requirements:
* The table must reference the ProductID column in the Product table
* Existing records in the ProductReview table must not be validated with the Product table.
* Deleting records in the Product table must not be allowed if records are referenced by the
ProductReview table.
* Changes to records in the Product table must propagate to the ProductReview table.
You also have the following database tables: Order ProductTypes, and SalesHistory. The transact-SQL statements for these tables are not available.
You must modify the Orders table to meet the following requirements:
* Create new rows in the table without granting INSERT permissions to the table.
* Notify the sales person who places an order whether or not the order was completed.
You must add the following constraints to the SalesHistory table:
* a constraint on the SaleID column that allows the field to be used as a record identifier
* a constant that uses the ProductID column to reference the Product column of the ProductTypes table
* a constraint on the CategoryID column that allows one row with a null value in the column
* a constraint that limits the SalePrice column to values greater than four Finance department users must be able to retrieve data from the table for sales persons where the value of the SalesYTD column is above a certain threshold.
You plan to create a memory-optimized table named . The table must meet the following requirements:
* The table must hold 10 million unique sales orders.
* The table must use checkpoints to minimize I/O operations and must not use transaction logging.
* Data loss is acceptable.
Performance for queries against the SalesOrder table that use WHERE clauses with exact equality operations must be optimized.
You need to modify the environment to meet the requirements for the Orders table.
What should you create?
A. an AFTER UPDATE trigger
B. a user defined function
C. a FOR UPDATE trigger
D. a stored procedure with the RETURN statement
Answer: B
QUESTION NO: 2
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
You have a database named dbReporting. Users run a large number of read-only ad hoc queries against the database. The application and all ad hoc queries use default database transaction isolation levels. You set the value of the READ_COMMITTED_SNAPSHOT database option to ON.
You have an application that updates 10 tables sequentially and modifies a large volume of records in a single transaction. The updates are isolated from each other.
Users report an error which indicates that the version store us full.
You need to reduce the number of occurrences of the error.
Solution: You increase the maximum database size for the dbReporting database.
Does the solution meet the goal?
A. Yes
B. No
Answer: B
QUESTION NO: 3
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are a database developer for a company. The company has a server that has multiple physical disks. The disks are not part of a raid array. The server hosts three Microsoft SQL Server instances.
There are many SQL jobs that run during off-peak hours.
You must monitor the SQL Server instances in real time and optimize the server to maximize throughput, response time, and overall SQL performance.
You need to examine delays in executed threads, including errors with specific queries and batches.
A. Create a Performance Monitor Data Collector Set.
B. Create a ays .dm_os_memory_objeccs query.
C. Create a sys.dm_exec_sessions query.
D. Create a sys.dm_os_waitingtasks query.
E. Create a sp_configure 'max server memory' query.
Answer: C
QUESTION NO: 4
You use Microsoft SQL Server Profile to evaluate a query named Query1. The Profiler report indicates the following issues:
* At each level of the query plan, a low total number of rows are processed.
* The query uses many operations. This results in a high overall cost for the query.
You need to identify the information that will be useful for the optimizer.
What should you do?
A. Start a SQL Server Profiler trace for the event class Performance statistics in the Performance event category.
B. Create one Extended Events session with the sqlserver.error_reported event added.
C. Start a SQL Server Profiler trace for the event class Soft Warnings in the Errors and Warnings event category.
D. Create one Extended Events session with the sqlserver.missing_column_statistics event added.
Answer: A
Explanation
The Performance Statistics event class can be used to monitor the performance of queries, stored procedures, and triggers that are executing. Each of the six event subclasses indicates an event in the lifetime of queries, stored procedures, and triggers within the system. Using the combination of these event subclasses and the associated sys.dm_exec_query_stats, sys.dm_exec_procedure_stats and sys.dm_exec_trigger_stats dynamic management views, you can reconstitute the performance history of any given query, stored procedure, or trigger.
