You have a trigger named CheckTriggerCreation that runs when a user attempts to create a trigger. The CheckTriggerCreation trigger was created with the ENCRYPTION option and additional proprietary business logic.
You need to prevent users from running the ALTER and DROP statements or the sp_tableoption stored procedure.
Which three Transact-SQL segments should you use to develop the solution? 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.

QUESTION NO: 3
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.

QUESTION NO: 7
You manage a database that supports an internal of Things (IOT) solution. The database records metrics from over 100 million devices every minute. The database requires 99.995 uptime.
The database uses a table named checkins that is 100 gigabytes (GB) in size. The checkins table stores metrics from the devices. The database also has a table named Archive that stores four terabytes (TB) of data. You use store produce for all access to the tables.
You observe that the wait type PAGELATCH_ to causes large amount of blocking.
You need to resolve the blocking issues while minimizing downtime for the database.
Which two actions should you perform? Each correct answer present part of the solution.

QUESTION NO: 9
You need to implement triggers to automate responses to the following events:
* SQL Server logons
* Database schema changes
* Database updates
Which trigger types should you use? To answer, drag the appropriate trigger types to the appropriate scenarios.
Each trigger type 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.
NOTE: Each correct selection is worth one point.

NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation
Box 1: LOGON
Logon triggers fire stored procedures in response to a LOGON event. This event is raised when a user session is established with an instance of SQL Server.
Box 2: INSTEAD OF INSERT
An "INSTEAD of trigger" is executed instead of the original operation, and not combining with the operation.
INSTEAD OF triggers override the standard actions of the triggering statement. It can be used to bypass the statement and execute a whole different statement, or just help us check and examine the data before the action is done.
Box 3: DDL
DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database Note:
You can write triggers that fire whenever one of the following operations occurs:
* DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user
* DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database
* Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database References:

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.
