• Question 365:

  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.

  Start of repeated scenario.

  You have five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the following diagram.

  

  You have an Always On Availability group named AG1. The details for AG1 are shown in the following table.

  

  Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMain that is four terabytes (TB) in size. The database has multiple data files and filegroups. One of the filegroups is read_only and is half of the

  total database size.

  Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O.

  Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two nonclustered rowstore indexes.

  You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK INSERT transaction. Changes made must not interrupt the log backup chain.

  You plan to add a new instance named Instance6 to a datacenter that is geographically distant from Site1 and Site2. You must minimize latency between the nodes in AG1.

  All databases use the full recovery model. All backups are written to the network location \\SQLBackup\. A separate process copies backups to an offsite location. You should minimize both the time required to restore the databases and the

  space required to store backups. The recovery point objective (RPO) for each instance is shown in the following table.

  

  Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION.

  You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1.

  Reporting system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader role. The user has EXECUTE permissions on the database. Queries make no changes to the data.

  The queries must be load balanced over variable read-only replicas.

  Operations system: This solution accesses data inDB1with a login that is mapped to a database user that is a member of the db_datareader and db_datawriter roles. The user has EXECUTE permissions on the database. Queries from the

  operations system will perform both DDL and DML operations.

  The wait statistics monitoring requirements for the instances are described in the following table.

  

  End of repeated scenario.

  You need to create a backup plan for Instance4.

  Which backup plan should you create?

  A. Weekly full backups, nightly differential backups, transaction log backups every 30 minutes.
  B. Weekly full backups, nightly differential. No transaction log backups are necessary.
  C. Weekly full backups, nightly differential backups, transaction log backups every 12 hours.
  D. Full backups every 60 minutes, transaction log backups every 30 minutes.
  A. Weekly full backups, nightly differential backups, transaction log backups every 30 minutes.

• Question 366:

  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 manage a Microsoft SQL Server environment. You implement Transparent Data Encryption (TDE).

  A user will assist in managing TDE.

  Which permission should you grant?

  A. DDLAdmin
  B. db_datawriter
  C. dbcreator
  D. dbo
  E. View Database State
  F. View Server State
  G. View Definition
  H. sysadmin
  G. View Definition

• Question 367:

  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.

  You need to recommend a solution that addresses the security requirement. What should you recommend?

  A. Revoke user permissions on the tables. Create stored procedures that manipulate data. Grant the users the EXECUTE permission on the stored procedures.
  B. Grant the users the SELECT permission on the tables. Create views that retrieve data from the tables. Grant the users the SELECT permission on the views.
  C. Deny the users SELECT permission on the tables. Create views that retrieve data from the tables. Grant the users the SELECT permission on the views.
  D. Deny the users the SELECT permission on the tables. Create stored procedures that manipulate data. Grant the users the EXECUTE permission on the stored procedures.
  C. Deny the users SELECT permission on the tables. Create views that retrieve data from the tables. Grant the users the SELECT permission on the views.

• Question 368:

  You create a stored procedure that retrieves all of the rows from a table named Table1.

  You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if another transaction is modifying rows in Table1 simultaneously.

  What should you recommend?

  A. Snapshot isolation
  B. A database snapshot
  C. Filegroups
  D. Indexes
  A. Snapshot isolation

• Question 369:

  You have an application that queries a database. Users report that the application is slower than expected.

  You discover that several server process identifiers (SPIDs) have PAGELATCH_UP and PAGELATCH_EX waits. The resource descriptions of the SPIDs contains 2:1:1.

  You need to resolve the issue.

  What should you do?

  A. Allocate additional processor cores to the server.
  B. Add files to the file group of the application database.
  C. Reduce the fill factor of all clustered indexes.
  D. Add data files to tempdb.
  D. Add data files to tempdb.
