Background
You have a database named HR1 that includes a table named Employee.
You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running.
You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires.
Employee Table
You use the following Transact-SQL statements to create, configure, and populate the Employee table:

Application
You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously:
- UspA: This stored procedure updates only the EmployeeStatus column.
- UspB: This stored procedure updates only the EmployeePayRate column.
The application uses views to control access to data. Views must meet the following requirements:
- Allow user access to all columns in the tables that the view accesses.
- Restrict updates to only the rows that the view returns.
Exhibit

Users must only be able to modify data in the Employee table by using the vwEmployee view. You must prevent users from viewing the view definition in catalog views.
You need to identify the view attribute to use when creating vwEmployee.
In the table below, identify the attributes that you must use.
NOTE: Make only one selection in each column.

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 named Sales 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:
* Optimize the performance and data integrity of the tables.
* Provide a custom error if a user attempts to create an order for a customer that does not exist.
* In the Customers table, update the value for the last order placed.
* Complete all actions as part of the original transaction.
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.

Correct Answer:

Explanation

INSTEAD OF INSERT triggers can be defined on a view or table to replace the standard action of the INSERT statement.
AFTER specifies that the DML trigger is fired only when all operations specified in the triggering SQL statement have executed successfully.

You have two databases with the following settings:

You run the following Transact -SQL statements:

You need to select data from DiskTable and insert the data into MemTable. You must complete the insertion operation into MemTable as an explicit transaction without immediate durability.
Which four Transact-SQL segments should you use? To answer, move the appropriate Transact-SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.

Correct Answer:

Explanation

Box 1: BEGIN TRANSACTION
Box 2: UPDATE ... #Disktable
Box 3: IF... SELECT INTO ...#Disktable
Box 4: .. DELAYED_DURABILITY = ON
The COMMIT syntax is extended so you can force delayed transaction durability. If DELAYED_DURABILITY is DISABLED or FORCED at the database level (see above) this COMMIT option is ignored.
Syntax:
COMMIT [ { TRAN | TRANSACTION } ] [ transaction_name | @tran_name_variable ] ] [ WITH ( DELAYED_DURABILITY = { OFF | ON } ) ] References:

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 ays .dm_os_memory_objeccs query.
• B.Create a Performance Monitor Data Collector Set.
• C.Create a sys.dm_exec_sessions query.
• D.Create a sp_configure 'max server memory' query.
• E.Create a sys.dm_os_waiting^tasks query.

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 need to identify the indexes that are not being used so that you can remove them from the database.
Solution: You run the sys.dm_db_index_usage_stats dynamic management view.
Does the solution meet the goal?

• A.Yes
• B.No
