• Question 245:

  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 minimize the amount of time it takes to execute USP_1. With what should you recommend replacing Table1?

  A. A view
  B. A temporary table
  C. A table variable
  D. A function
  A. A view

• Question 248:

  Overview Application Overview

  Contoso, Ltd., is the developer of an enterprise resource planning (ERP) application.

  Contoso is designing a new version of the ERP application. The previous version of the ERP application used SQL Server 2008 R2.

  The new version will use SQL Server 2014.

  The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily. You receive several support calls reporting

  unexpected behavior in the ERP application. After analyzing the calls, you conclude that users made changes directly to the tables in the database.

  Tables

  The current database schema contains a table named OrderDetails.

  The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order. The product price is stored in a table named

  Products. The Products table was defined by using the SQL_Latin1_General_CP1_CI_AS collation.

  A column named ProductName was created by using the varchar data type. The database contains a table named Orders.

  Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12 months are stored in a table named OrdersOld.

  The previous version of the ERP application relied on table-level security.

  Stored Procedures

  The current version of the database contains stored procedures that change two tables. The following shows the relevant portions of the two stored procedures:

  

  Customer Problems

  Installation Issues

  The current version of the ERP application requires that several SQL Server logins be set up to function correctly. Most customers set up the ERP application in multiple locations and must create logins multiple times.

  Index Fragmentation Issues

  Customers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently. All of the tables affected by fragmentation have the following columns that are used as the

  clustered index key:

  

  Backup Issues

  Customers who have large amounts of historical purchase order data report that backup time is unacceptable.

  Search Issues

  Users report that when they search product names, the search results exclude product names that contain accents, unless the search string includes the accent.

  Missing Data Issues

  Customers report that when they make a price change in the Products table, they cannot retrieve the price that the item was sold for in previous orders.

  Query Performance Issues

  Customers report that query performance degrades very quickly. Additionally, the customers report that users cannot run queries when SQL Server runs maintenance tasks. Import Issues During the monthly import process, database

  administrators receive many supports call from users who report that they cannot access the supplier data. The database administrators want to reduce the amount of time required to import the data.

  Design Requirements

  File Storage Requirements

  The ERP database stores scanned documents that are larger than 2 MB. These files must only be accessed through the ERP application. File access must have the best possible read and write performance.

  Data Recovery Requirements

  If the import process fails, the database must be returned to its prior state immediately.

  Security Requirements

  You must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.

  Concurrency Requirements

  You must reduce the likelihood of deadlocks occurring when Sales.Prod and Sales.Proc2 execute.

  What should you recommend for the updates to Sales.TransactionHistory?

  A. a REPEATABLE READ isolation level
  B. implicit transactions
  C. query hints
  D. a SNAPSHOT isolation level
  A. a REPEATABLE READ isolation level

• Question 249:

  HOTSPOT

  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 SalesDb2. 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.

  You need to monitor query statistics and execution plans for SalesDb2.

  Which options should you set for the Query Store configuration? To answer, select the appropriate options in the answer area.

  

  Hot Area:

  

  

  ---

  Operation Mode: Read-Write

  Query Store Capture Mode: Auto

  Size Based Cleanup Mode: AUTO

  Operation Mode: Read-Write

  It is strongly recommended to activate size-based cleanup to makes sure that Query Store always runs in read-write mode and collects the latest data.

  Query Store Capture Mode: Auto

  Auto -Infrequent queries and queries with insignificant compile and execution duration are ignored. Thresholds for execution count, compile and runtime duration are internally determined.

  Size Based Cleanup Mode: AUTO

  It is strongly recommended to activate size-based cleanup to makes sure that Query Store always runs in read-write mode and collects the latest data.

  OFF -size based cleanup won't be automatically activated.

  AUTO - size based cleanup will be automatically activated when size on disk reaches 90% of max_storage_size_mb. This is the default configuration value.

  Size based cleanup removes the least expensive and oldest queries first. It stops at approximately 80% of max_storage_size_mb.
