You administer a Microsoft SQL Server 2016 instance. The instance contains a database that supports a retail sales application.
The application generates hundreds of transactions per second and is online 24 hours per day and 7 days per week. You plan to define a backup strategy for the database.
You need to ensure that the following requirements are met:
* No more than 5 minutes worth of transactions are lost.
* Data can be recovered by using the minimum amount of administrative effort.
What should you do? Choose all that apply.

You plan to install a Microsoft SQL Server 2016 instance.
The instance will support a database that has the following requirements:
* Store Excel workbooks on the file system.
* Access the workbooks through Transact-SQL.
* Include the workbooks in database backups.
* During installation, you need to ensure that the requirements will be met.
Which feature should you use?

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
Your company is developing a new business intelligence application that will access data in a Microsoft Azure SQL Database instance. All objects in the instance have the same owner.
A new security principal named BI_User requires permission to run stored procedures in the database. The stored procedures read from and write to tables in the database. None of the stored procedures perform IDENTIFY_INSERT operations or dynamic SQL commands.
The scope of permissions and authentication of BI_User should be limited to the database. When granting permissions, you should use the principle of least privilege.
You need to create the required security principals and grant the appropriate permissions.
Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

You administer a Microsoft SQL Server database named Contoso. You create a stored procedure named Sales.ReviewInvoice by running the following Transact-SQL statement:

You need to create a Windows-authenticated login named SalesGroup and ensure that SalesGroup can run the Sales.ReviewInvoice 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.

You have a database named DB1 that contains a table named Table1. You need to audit all updates to Table1.
Solution: You convert Table1 to a system-versioned temporal table. Does this meet the goal?

Overview
General Overview
ADatum Corporation has offices in Miami and Montreal.
The network contains a single Active Directory forest named adatum.com. The offices connect to each other by using a WAN link that has 5-ms latency.
A: Datum standardizes its database platform by using SQL Server
2014 Enterprise edition.
Databases
Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev.
Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases.
The Customers database contains two tables named Customers and Classifications.
The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:

The Inventory database is updated frequently.
The database is often used for reporting.
A full backup of the database currently takes three hours to complete.
Stored Procedures
A stored procedure named USP_1 generates millions of rows of data for multiple reports. USP_1 combines data from five different tables from the Sales and Customers databases in a table named Table1.
After Table1 is created, the reporting process reads data from Table1 sequentially several times. After the process is complete, Table1 is deleted.
A stored procedure named USP_2 is used to generate a product list. The product list contains the names of products grouped by category.
USP_2 takes several minutes to run due to locks on the tables the procedure accesses. The locks are caused by USP_1 and USP_3.
A stored procedure named USP_3 is used to update prices. USP_3 is composed of several UPDATE statements called in sequence from within a transaction.
Currently, if one of the UPDATE statements fails, the stored procedure fails. A stored procedure named USP_4 calls stored procedures in the Sales, Customers, and Inventory databases.
The nested stored procedures read tables from the Sales, Customers, and Inventory databases. USP_4 uses an EXECUTE AS clause.
All nested stored procedures handle errors by using structured exception handling. A stored procedure named USP_5 calls several stored procedures in the same database. Security checks are performed each time USP_5 calls a stored procedure.
You suspect that the security checks are slowing down the performance of USP_5. All stored procedures accessed by user applications call nested stored procedures.
The nested stored procedures are never called directly.
Design Requirements
Data Recovery
You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Time Objective (RTO) of 5 minutes.
You must be able to recover data from the Dev database if data is lost accidentally. You have a Recovery Point Objective (RPO) of one day.
Classification Changes
You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future. Management requests that historical data be maintained for the previous classifications. Security A group of junior database administrators must be able to manage security for the Sales database. The junior database administrators will not have any other administrative rights.
A: Datum wants to track which users run each stored procedure.
Storage
ADatum has limited storage. Whenever possible, all storage space should be minimized for all databases and all backups.
Error Handling
There is currently no error handling code in any stored procedure.
You plan to log errors in called stored procedures and nested stored procedures. Nested stored procedures are never called directly.
You need to recommend a solution to meet the security requirements of the junior database administrators.
What should you include in the recommendation?

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 maintain a Microsoft SQL Server instance that contains the following databases SalesDb1, SalesDb2, and SalesDb3. Each database has tabled named Products and Sales. The following table shows the configuration of each database.

The backup strategies for each database are described in the following table.

Each full or differential backup operation writes into a new file and uses a different sequence number. You observe the following database corruption issues.

SalesDb3 reports a number of database corruption issues related to error 823 and 824 when reading data pages.
You must display the following information about the corrupted pages:
* database name
* impacted file id
* impacted file physical name
* impacted page id
* event type that identifies the error type
* error count
Users report performance issues when they run queries against You plan to monitor query statistics and execution plans for SalesDb2 by using Query Store. The monitoring strategy must meet the following requirements:
* Perform automatic data cleanup when query store disk usage reaches 500 megabyte (MB).
* Capture queries based on resource consumption.
* Use a stale query threshold value of 60 days.
The query optimizer generates suboptimal execution plans for a number of queries on the Sales table in SalesDb2. You will create a maintenance plan that updates statistics for the table. The plan should only update statistics that were automatically created and have not been updated for 30 days. The update should be based on all data in the table.
Users reports that they encounter the following error when they query SalesDb1: "SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x5d672d9b; actual: 0xdd672d98). It occurred during a read of page (1.232) in database ID 12 at offset 0x000000001d0000 in file F:\Databases\MSSQLServer Databases\MSSQL13.MSSQL2016\MSSQL\DATA\SalesDb1.mdt." You must restore the impacted page from SalesDb1Full_1.bak. A single backup set named SalesDb1Log.bak was created since the latest full backup operation.
You need to restore the impacted page.
Which four 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.

A company has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environments host several customer databases.
You configure an Always On Availability Group for a customer. You must create log reports for the customer that detail when the log is flushed to disk on the primary and secondary replica.
You need to develop a report containing the requested information.
In the table below, identify the log type that you should use for each replica.
NOTE: Make only one selection in each column. Each correct selection is worth one point.

You administer a Microsoft SQL Server 2016 database named Contoso that contains a single user-defined database role namedBillingUsers.
All objects in Contoso are in the dbo schema.
You need to grant EXECUTE permissions for all stored procedures in Contoso to BillingUsers.
Which Transact-SQL statement should you use?

You use SQL Server 2014 Enterprise Edition.
Your database contains a partitioned table named AuditData. AuditData is partitioned by year. Partition 1 contains data from the year 2010 and prior.
Management has decided to archive all AUDITDATA records from 2010 and prior.
Management wants the records to be removed from the database entirely and provided to the backup team as a zipped text file. The data must no longer reside in the database.
There is very little tolerance for performance degradation in your environment. You need to remove all 2010 and prior data from the AuditData table by using the least amount of system resources possible. Develop the solution by selecting and arranging the required SQL actions in the correct order.
You may not need all of the actions.
