HOTSPOT
You have a database named Sa les that contains the following database tables: Customer, Order, and Products.
The Products table and the Order table are shown in the following diagram.
The customer table includes a column that stores the data for the last order that the customer placed.
You plan to create a table named Leads. The Leads table is expected to contain approximately 20,000 records. Storage requirements for the Leads table must be minimized.
You need to create triggers that meet the following requirements:
In the table below, identify the trigger types that meet the requirements.
NOTE: Make only selection in each column. Each correct selection is worth one point.
Answer:
You are developing and application to track customer sales. You need to return the sum of orders that have been finalized, given a specified order identifier. This value will be used in other Transact-SOL statements. You need to create a database object. What should you create?

Answer: F
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 ensure that the performance of each instance is consistent for the same queried and query plans. What should you do?
A. Create a sys.dm_os_waiting_tasks query.
B. Create a sys.dm_exec_sessions query.
C. Create a Performance Monitor Data Collector Set.
D. Create a sys.dm_os_memory_objects query.
E. Create a sp_conftgure ‘max server memory’ query.
F. Create aSQL Profiler trace.
G. Create asys.dm_os_wait_stats query.
H. Create an Extended Event.
Answer: H

DRAG DROP
You have a database named Sales that contains the following database tables. Customer, Order, and Products.
The Products table and the order table shown in the following diagram.
The Customer table includes a column that stores the date for the last order that the customer placed.
You plan to create a table named Leads. The Leads table is expected to contain approximately 20,000 records. Storage requirements for the Leads table must be minimized.
You need to begin to modify the table design to adhere to third normal form.
Which column should you remove for each table? To answer? Drag the appropriate column names to the correct locations. Each column name may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Answer:
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:
1. The table must reference the ProductID column in the Product table
2. Existing records in the ProductReview table must not be validated with the Product table.
3. Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
4. 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-SOL statements for these tables are not available.
You must modify the Orders table to meet the following requirements:
1. Create new rows in the table without granting INSERT permissions to the table.
2. 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 Sale Price column to values greater than four Finance department users must be able to retrieve data from the SalesHistory 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 SalesOrder.
The table must meet the following requirements:
– The table must hold 10 million unique sales orders.
– The table must use checkpoints to minimize 1/0 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 enable referential integrity for the ProductReview table.
How should you complete the relevant Transact-SOL statement? To answer? Select the appropriate Transact-SOL segments in the answer area.
Select two alternatives.
A. For the first selection select: WITH CHECK
B. For the first selection select: WITH NOCHECK
C. For the second selection select: ON DELETE NO ACTION ON UPDATE CASCADE
D. For the second selection select: ON DELETECASCADE ON UPDATE CASCADE
E. For the second selection select: ON DELETE NO ACTION ON UPDATE NO ACTION
F. For the second selection select: ON DELETE CASCADE ON UPDATE NO ACTION

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 create a baseline set of metrics to report how the computer running SQL Server operates under normal load. The baseline must include the resource usage associated with the server processes. What should you do?
A. A. Create a sys.dm_os_waiting_tasks query.
B. Create a sys.dm_exec_sessions query.
