• Question 425:

  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 for the error handling of USP_3. The solution must minimize the amount of custom code required. What should you recommend?

  A. Use the @@ERROR variable in the nested stored procedures.
  B. Use a TRY CATCH block in the called stored procedures.
  C. Use the @@ERROR variable in the called stored procedures.
  D. Use the RAISERROR command in the nested stored procedures.
  B. Use a TRY CATCH block in the called stored procedures.

  You administer a SQL Server Instance at Contoso Ltd.

  A new employee named Kim Ralls must be able to read data only from the dbo.Order table in the SalesDB database.

  You create a SQL login named KimRalls. You then create a SQL user account named KimRalls in SalesDB. The user account is associated with the SQL login.

  You need to grant KimRalls the necessary permission or permissions. Your solution must follow the principle of least privilege.

• Question 428:

  B. You should configure a Server Role.
  C. You should configure a Shared SQL Server Login.
  D. You should configure a Local Security Group.
  B. You should configure a Server Role.

• Question 429:

  DRAG DROP

  You plan to deploy SQL Server 2014.

  Your company identifies the following monitoring requirements for the database:

  An e-mail message must be sent when a user logs in.

  An e-mail message must be sent if CPU utilization exceeds 90 percent

  You need to identify which feature meets each monitoring requirement.

  Which features should you identify? To answer, drag the appropriate feature to the correct monitoring requirement in the answer area.

  You support an application that stores data in a Microsoft SQL Server database. You have a query that returns data for a report that users run frequently.

  The query optimizer sometimes generates a poorly-performing plan for the query when certain parameters are used. You observe that this is due to the distribution of data within a specific table that the query uses.

  You need to ensure that the query optimizer always uses the query plan that you prefer.

  Solution: You create a plan guide for the query by using the desired query plan and the sp_create_plan_guide stored procedure.

  Does the solution meet the goal?

  A. Yes
  B. No
  B. No
