Case Scenario 7 (Chapter 4 - Case Scenario 1): Consolidation at Contoso

Contoso has 20 database servers running a mix of SQL Server 2005 and SQL Server 2008. All existing database servers are running x86 versions of SQL Server. Contoso has recently deployed 20 virtual machines that have the x64 version of SQL Server 2012 Enterprise edition in their private cloud. You want to start by deploying databases from 10 instances to an instance hosted in the private cloud used for development work. During the development phase of the project, these databases should also remain hosted on their original parent instances. Each database instance has between 10 and 100 SQL logins, which all use Windows authentication.

With this information in mind, answer the following questions:

  1. What steps should you take to migrate the databases during the development phase of the project? Answer.

    You should copy the databases from the production hosts to the virtual machines in the development private cloud. You could use the backup and restore method of copying the databases or the Copy Database Wizard by using the object model to perform the copy. The key is that your strategy should ensure that the databases on the production server remain online.

    Hide the Answer.

  2. Describe the steps that you would take to migrate the SQL logins from the original instances to the new instances. Answer.

    You should use the Script Login As method of migrating the SQL logins because the problem statement says that all logins use Windows authentication. You might also consider using the script published with Knowledge Base article KB918992, which enables you to automate the migration of both SQL Server–authenticated and Windows-authenticated SQL logins, although in this case, because you don’t have to worry about migrating passwords, the Script Login As method might be simpler. You can also use the Copy Database Wizard to migrate the logins.

    Hide the Answer.

  3. What factors will influence whether you perform a backup and restore method or a detach and attach method when it comes to migrating the databases prior to deploying them in the private cloud environment? Answer.

    A detach operation takes the database offline from its current instance. Although you can make a copy of the files and then reattach on the original instance and the desti- nation instance, using the Backup and Restore method of copying a database ensures that the database remains online on the original host during the migration.

    Hide the Answer.

Case Scenario 8 (Chapter 4 - Case Scenario 2): Tailspin Toys Bulk Data

Tailspin Toys has a number of SQL Server 2012 instances deployed on traditional hardware. It is necessary to export a substantial amount of data from the database on a regular basis. The data is the entire contents of specific tables and must be written to Excel format. It is also necessary on occasion to import a substantial amount of customer data from a specially prepared file into one of the databases.

With this information in mind, answer the following questions.

  1. You have a file that contains customer names, phone numbers, and addresses. Which command-line utility would you use to import this data into a table on a database instance? Answer.

    2. You use the bcp utility to import data into the database from the command line.

    Hide the Answer.

  2. Every week, you must perform a bulk export of data from the database. What steps could you take to automate this process? Answer.

    Use the SQL Server Import and Export Wizard to create an Integration Services package. Schedule the package to execute on a periodic basis.

    Hide the Answer.

  3. You must copy the contents of several large tables to new tables on a different database hosted on the same instance. Which method could you use to accomplish this goal? Answer.

    You could use the SELECT...INTO statement to copy the contents of existing tables quickly into new tables if the new tables are associated with a different database hosted on the same instance.

    Hide the Answer.

Case Scenario 9 (Chapter 5 - Case Scenario 1): Instance-Level Permissions for Contoso’s Accountants

You are the database administrator at Contoso, and you are deploying an instance of SQL Server 2012 that members of the accounting and finance departments will use. All members of the accounting and finance departments have accounts in the Contoso Active Directory domain. There are no accounting or finance-based domain security groups. In the accounting department are 20 users who require access to the SQL Server 2012 instance. These users require specific permissions that differ from those available in the fixed server-level roles. In the next few months, members of the finance department might need similar access and permissions. You want to configure security so that the number of SQL logins is minimized but also so that members of the accounting department do not share a SQL login with members of the finance department. With this in mind, answer the following questions:

  1. What steps should you take to minimize the number of SQL Server logins when granting access to the 20 accounting users? Answer.

    2. Create a domain group and add the 20 users in the accounting department to this group. Create a SQL Server login that uses the Windows authentication type and is mapped to this domain group.

    Hide the Answer.

  2. What approach should you take when granting the custom permissions at the Database Engine instance level? Answer.

    Create a user-defined server role. Grant the custom permissions to this user-defined server role. Add the SQL Server login mapped to the group holding the accounting department user accounts to this user-defined server role. In the future, you will be able to add other logins to this role, such as a login relating to the finance users.

    Hide the Answer.

Case Scenario 10 (Chapter 5 - Case Scenario 2): Contained Databases at Fabrikam

You are the SQL Server 2012 database administrator at Fabrikam, and you are planning a new database. One of the goals in developing this new database is for you to be able to attach and detach the database as necessary from different instances without creating orphaned users. All instances that host the database will be running SQL Server 2012. All users who will access the database have accounts in the Fabrikam Active Directory domain. They should be able to connect to the database without entering a separate password. Each user might require different permissions on the database.

With this information in mind, answer the following questions:

  1. Prior to creating the database, what steps should you take to prepare the instance? Answer.

    You should configure the instance to support contained database authentication. This enables you to attach and detach the database from different instances without creating orphaned users.

    Hide the Answer.

  2. What type of security principal should you configure in the database? Answer.

    You should create contained database users that map to domain-based user accounts.

    Hide the Answer.

Case Scenario 11 (Chapter 6 - Case Scenario 1): Configuring Database Permissions

You are developing permissions for the Production database. This database has two schema, named Accounts and Manufacturing. The database has three roles, named Finance, DataProtection, and Engineering.

  1. You must ensure that principals in the Finance role can add and change data on tables in the Accounts schema. Which permissions must you grant to accomplish this goal? Answer.

    2. They will need SELECT permission to view the data, INSERT permission to add data, and UPDATE permission to modify data.

    Hide the Answer.

  2. Members of the DataProtection role must be able to back up and recover data stored in the Protection database. Which permissions must you assign this role? Answer.

    Backup permission grants permission to back up a securable. Restore permission allows a securable to be recovered from backup.

    Hide the Answer.

  3. Which permission must the Engineering role have on the Manufacturing schema if members of that role must be able to create and drop tables in the schema? Answer.

    They must be assigned the ALTER permission to create and drop tables in the schema.

    Hide the Answer.

Case Scenario 12 (Chapter 6 - Case Scenario 2): Troubleshooting Security

You are auditing the security of a subsidiary company’s SQL Server 2012 databases. A previ- ous database administrator implemented certificates and asymmetric keys for database authentication and authorization. The database administrator has since moved on, and you must determine the properties of certificates and keys, including when certificates will expire, when private keys were last backed up, and the key lengths used when generating asymmet- ric keys. With these requirements in mind, answer the following questions:

  1. Which security catalog view would you query to determine the expiration dates of database certificates? Answer.

    2. You can query the sys.certificates catalog view to determine the expiration date of database certificates.

    Hide the Answer.

  2. Which security catalog view would you query to determine when the private key for a specific certificate was last backed up? Answer.

    You can query the sys.certificates catalog view to determine the most recent date on which a certificate’s private key was backed up.

    Hide the Answer.

  3. Which security catalog view would you query to determine the key length of the asym- metric keys? Answer.

    You can query the sys.asymmetric_keys catalog view to determine the key length of asymmetric keys.

    Hide the Answer.

Case Scenario 13 (Chapter 6 - Case Scenario 3): Auditing at Fabrikam

You are configuring auditing for several databases hosted on the default instance of server SYD-SQL-A. You are working on this configuration with a colleague. With this situation in mind, answer the following questions:

  1. Which permissions do you need to be able to create a database audit specification? Answer.

    2. You need either the ALTER ANY DATABASE AUDIT permission or the ALTER or CONTROL permissions on the database.

    Hide the Answer.

  2. Which step should you take to ensure that both successful and failed audits are logged on the default instance on SYD-SQL-A? Answer.

    Configure Login Auditing at the instance level. Enabling common criteria compliance and c2 audit tracing also accomplishes this goal.

    Hide the Answer.

  3. You want to check how your colleague has configured auditing. Which catalog view would you query to determine which actions are audited at the database level? Answer.

    You can query the sys.database_audit_specifications_details catalog view to learn detailed information about auditing at the database level.

    Hide the Answer.

Case Scenario 14 (Chapter 7 - Case Scenario 1): Database Mirroring at Coho Vineyard

You are the database administrator at Coho Vineyard. You have just migrated the Winery database from a host server running SQL Server 2005 to a new server named Sydney-SQL-A running SQL Server 2012. Your organization has purchased two additional servers, named Sydney-SQL-B and Sydney-SQL-C. You have installed SQL Server 2012 on both of these serv- ers, which will host their own databases, but you will also use them to support the Winery database in a mirrored configuration. You want to configure the mirroring session in the following ways:

  • The default instance on Sydney-SQL-A will serve as the principal instance.
  • The default instance on Sydney-SQL-B will serve as the mirroring instance.
  • The default instance on Sydney-SQL-C will serve as the witness instance.

You have configured the SQL Server service accounts on each instance as follows:

  • The SQL Server Service uses a domain account named cohovineyard\syd-sql-a.
  • The SQL Server Service uses a domain account named cohovineyard\syd-sql-b.
  • The SQL Server Service uses a domain account named cohovineyard\syd-sql-c.

With this information in mind, answer the following questions:

  1. Which logins must you create on instance Sydney-SQL-B? Answer.

    2. You must create logins for accounts cohovineyard\syd-sql-a and cohovineyard\syd-sql-b so that the principal instance and the witness instance can be granted permissions on the endpoint.

    Hide the Answer.

  2. Which mode would you set to ensure that automatic failover can occur if instance Sydney-SQL-A becomes unavailable? Answer.

    You must set high-safety mode with a witness present to enable automatic failover.

    Hide the Answer.

  3. Which Transact-SQL statement would you use to make Sydney-SQL-B the primary instance when you must apply software updates that require restarting server Sydney-SQL-A? Answer.

    Use the ALTER DATABASE Winery SET PARTNER FAILOVER; statement to make the mirror instance the primary instance when applying software updates.

    Hide the Answer.

Case Scenario 15 (Chapter 7 - Case Scenario 2): Database Replication at Tailspin Toys

Tailspin Toys has offices in the cities of Melbourne, Sydney, Perth, Adelaide, Brisbane, and Hobart. Each office has its own SQL Server 2012 Enterprise edition instance. Tailspin Toys has three databases, which must be hosted in each of these cities. These databases have the following properties:

  • Airplanes Is updated frequently at the Melbourne office. Is not updated at any other office. Other offices must stay up to date with the changes made at the Melbourne office.
  • Hovercraft Is updated between 6:00 P.M. and 7:00 P.M. each weekday at the Brisbane office. Is not updated at any other office. Other offices need the updates before start of business the next morning.
  • Multicopters All sites must be able to update this database. If conflicts occur when the same row is updated at different offices, updates applied at the Adelaide office should take precedence.

With this information in mind, answer the following questions:

  1. Which type of replication should you use for the Airplanes database? Answer.

    2. Transactional replication is suitable in this circumstance because updates occur at one location but must propagate quickly to other locations.

    Hide the Answer.

  2. Which type of replication should you use for the Hovercraft database? Answer.

    Snapshot replication is appropriate in this circumstance because updates occur at one location over a brief span of time, and a substantial amount of time elapses before other branch offices must be updated.

    Hide the Answer.

  3. Which type of replication should you use for the Multicopters database? Answer.

    Merge replication is appropriate in this circumstance because each office can update the database, and automatic conflict resolution is required.

    Hide the Answer.

Case Scenario 16 (Chapter 8 - Case Scenario 1): Failover Cluster Instances at Contoso

You are designing a failover cluster instance solution at Contoso. You will deploy a four-node failover cluster at the Melbourne site. You will also deploy a failover cluster instance that has nodes in the cities of Brisbane, Sydney, Adelaide, and Perth. Each of these cities resides on a different TCP/IP subnet.

With these facts in mind, answer the following questions:

  1. Which edition of SQL Server 2012 should you deploy to support the proposed cluster configuration at the Melbourne site? Answer.

    2. You must deploy SQL Server 2012 Enterprise edition to support the proposed cluster configuration because this is the only edition that supports four nodes.

    Hide the Answer.

  2. Which host operating systems can you use to support the proposed cluster configuration at the Brisbane, Sydney, Adelaide, and Perth sites? Answer.

    You must support multi-subnet failover clustering, which requires either Windows Server 2008 R2 Enterprise or Datacenter editions. Windows Server 2008 does not support multi-subnet failover clustering.

    Hide the Answer.

  3. Which tools can you use to perform manual failover when performing maintenance? Answer.

    You can use either the Failover Cluster manager or the Move-ClusterGroup PowerShell cmdlet to perform manual failover.

    Hide the Answer.

Case Scenario 17 (Chapter 8 - Case Scenario 2): AlwaysOn Availability Groups at Fabrikam

You are planning an AlwaysOn Availability Groups deployment at Fabrikam. Fabrikam wants to deploy replica instances in the cities of Sydney, Brisbane, Canberra, and Melbourne. Fabrikam security policy dictates that you must use local virtual accounts rather than domain security accounts for the SQL Server service accounts for each of the replica instances. The Chief Information Officer (CIO) at Fabrikam wants you to configure the AlwaysOn Availability Group so that automatic failover is possible.

With these facts in mind, answer the following questions:

  1. Which editions of Windows Server 2008 R2 could you use to support the proposed configuration? Answer.

    2. You can use the Enterprise or Datacenter editions of Windows Server 2008 R2 to support the proposed configuration.

    Hide the Answer.

  2. What factors influence the choice of authentication method for the mirroring endpoints? Answer.

    Because the SQL Server service uses local accounts, you must use certificate-based authentication for the endpoints.

    Hide the Answer.

  3. Which availability mode should you configure on the primary and secondary replicas, given the project requirements? Answer.

    You must configure the synchronous-commit availability mode, given the requirement for automatic failover.

    Hide the Answer.

Case Scenario 18 (Chapter 9 - Case Scenario 1): Identifying Poor Query Performance

You have recently deployed SQL Server 2012 Enterprise edition to a new server with 128 GB of memory. The Sales application was also upgraded as part of this deployment. The sales team has identified that the performance of the end-of-month report is no longer satisfactory after the upgrade. With this information in mind, answer the following questions:

  1. Which tool would you use to identify the query that this report is using? Answer.

    2. SQL Server Profiler can be used to help identify the slow query or queries executed by the report.

    Hide the Answer.

  2. How would you identify whether the unsatisfactory performance is caused by a missing index? Answer.

    When SQL Server processes a query, the optimizer keeps a record of the indexes it attempts to use to satisfy the query. If these indexes are not found, SQL Server creates a record of the missing index. This information can be viewed by using the sys.dm _ db_missing_index_details DMV.

    Hide the Answer.

Case Scenario 19 (Chapter 9 - Case Scenario 2): Deploying Auditing

You have upgraded the SQL Server for the Payroll database from SQL Server 2008 to SQL Server 2012. Due to new regulatory requirements, you need to audit when any updates are made to the Employee table in the database. The regulation specifies that the audit information must be stored in the Application Event Log and that all events must be audited. With this information in mind, answer the following questions:

  1. Which query would you use to create the server audit? Answer.

    2. CREATE SERVER AUDIT PayrollAudit
    TO APPLICATION_LOG
    WITH (QUEUE_DELAY = 0, ON_FAILURE = SHUTDOWN);
    GO

    Hide the Answer.

  2. How would you enable the server audit? Answer.

    ALTER SERVER AUDIT PayrollAudit
    WITH
    (

    STATE = ON )

    GO

    Hide the Answer.

  3. Which query would you use to audit the Employee table? Answer.

    CREATE DATABASE AUDIT SPECIFICATION EmployeeUpdateAudit
    FOR SERVER AUDIT PayrollAudit
    ADD
    (

    UPDATE ON HumanResources.Employees
    BY PUBLIC

    )
    WITH
    (

    STATE = ON

    )
    GO

    Hide the Answer.

Case Scenario 20 (Chapter 10 - Case Scenario 1): Fabrikam Year-Query Performance Optimized Logging

You are a database administrator for Fabrikam. You are testing a query that will be used for the year-end report. This report performs many aggregate operations such as min, max, avg, sum, and standard deviation. The performance of this query is unacceptable. You will be deploying this query on SQL Server 2012. The table that is involved with the aggregate operations contains 3.5 million rows. It has a clustered index on its primary key column.

There are several queries for which you have captured execution plans due to poor performance. When you examine those plans, you notice that one large table is often causing a table scan, which is the cause of the poor performance. You also determine that a particular query, which is being supported by a non-clustered index, is not very selective. You know that the WHERE clause contains two columns, one of which is the leading column of the nonclustered index. That column by itself is not very selective, but is very selective when combined with the second column. You cannot create an index at this time. A long-term reporting solution is required that will limit the impact on the OLTP system.

  1. Without rewriting the query, which has been tested to ensure that the proper calculations are being made, how could you improve performance of the query? Answer.

    2. Because your application will be deployed on SQL Server 2012, you perform many aggregate operations, and the table contains a large number of rows, you can create a columnstore index on the table to improve query performance for the aggregate operations.

    Hide the Answer.

  2. Which indexes could be added to improve performance? Answer.

    Examine the Missing Indexes DMVs to see whether an appropriate index exists that will remove the table scan from the execution plans.

    Hide the Answer.

  3. How can you improve the multicolumn query performance? Answer.

    Manually create statistics on the two columns. This will enable the optimizer to determine that the combination of the two columns is highly selective and choose a more optimum query plan.

    Hide the Answer.

  4. How can you design a long-term reporting solution? Answer.

    Implement Readable Secondary Replicas and have the reporting application set its connection string to include the ApplicationIntent=ReadOnly clause.

    Hide the Answer.

Case Scenario 21 (Chapter 10 - Case Scenario 2): Analyzing Concurrency at Tailspin Toys

You are a database administrator for Tailspin Toys. Users of your application are reporting that they are waiting significant amounts of time after they submit an order for it to process. During this time, you see that the Marketing team has been running its latest sales promo- tion reports. You examine sys.dm_os_waiting_tasks and sys.dm_exec_sessions and notice long blocking chains. Users are also reporting Error 1205 messages.

You cannot make source code changes at this time. What steps should you take to improve concurrency in the Tailspin Toys database?
  1. The server is under heavy load, and you cannot run a SQL Profiler trace because of this. How can you capture the necessary information to diagnose and correct the deadlocks? Answer.

    2. Because you are experiencing reader-writer blocking, you can set the Read Committed Snapshot Isolation database option to improve concurrency.

    You can enable deadlock information capture to the SQL Server activity log by execut- ing the DBCC TRACEON(1222,-1) command. This captures the information without the overhead of a SQL Server Profiler trace and does not require a service restart such as setting this trace flag as a start-up parameter.

  2. A maintenance job runs four times per day. Whenever this job runs, every process that needs access to the Status table is blocked until the maintenance job is complete. When the maintenance job is not executing, there are no issues. The maintenance job is reading data and copying it to a history table. Answer.

    The maintenance job might have its transaction set to SERIALIZABLE, effectively blocking all access to the Status table. Because only read access is required, you can remove the TRANSACTION ISOLATION LEVEL SERIALIZABLE statement. This will allow all connections access to the table while the maintenance job is being executed. Also, if correct, you can add a WITH NOLOCK hint to the maintenance job to improve concurrency as long as you are aware that you might get dirty reads.

Case Scenario 22 (Chapter 11 - Case Scenario 1): SQL Server Agent at Contoso

You are configuring automation at Contoso. Over the next week, a developer will be performing maintenance on the Hovercraft database. You have a number of alerts configured that trigger specific jobs and don’t want these jobs running while maintenance is being performed on the database. You’ve also been investigating running a Windows PowerShell script on a regular basis to perform system maintenance tasks. This Windows PowerShell script should run only if the results of a Transact-SQL query are successful. Finally, you want to ensure that your colleague, Kim, is contacted if other operators are unavailable. With these facts in mind, answer the following questions:

  1. How can you ensure that the Windows PowerShell script runs only after the Transact- SQL statement executes successfully? Answer.

    2. You can configure job steps so that the next step occurs only if the first step completes successfully.

    Hide the Answer.

  2. How can you ensure that alerts are not triggered for the next week but can be triggered after the maintenance is complete? Answer.

    Disable the alerts. You can re-enable them as necessary. While disabled, the jobs will not be triggered.

Case Scenario 23 (Chapter 11 - Case Scenario 2): Fabrikam Backup Strategy

You are developing a backup strategy at Fabrikam, which uses AlwaysOn Availability Groups as a high-availability solution. A large number of user databases are hosted on servers that are not members of availability groups. You have the following requirements:

  • Backups should be taken of secondary instances for the Victoria availability group only.
  • You want to create a backup device named file_backup on each server that uses the local file e:\store\file_backup.bak.
  • You should be able to perform a point-in-time recovery on any user database at Fabrikam.

With these facts in mind, answer the following questions:

  1. Which command should you issue to configure the Victoria availability group so that backups are taken only on the appropriate replicas? Answer.

    2. Issue the ALTER AVAILABILITY GROUP [Victoria] SET (AUTOMATED_BACKUP _PREFERENCE = SECONDARY_ONLY); command.

    Hide the Answer.

  2. Which command should you issue to create the appropriate backup device on each server? Answer.

    Execute the EXEC sp_addumpdevice ‘disk’, ‘file_backup’, ‘e:\store\file_backup.bak’ command to create the appropriate backup device.

    Hide the Answer.

  3. Which recovery model should all the databases at Fabrikam use? Answer.

    All databases will need to use the full recovery model to ensure that point-in-time recovery is possible.

  • You want to determine whether the HOVERCRAFT database on server SYD-SQL-D is in the emergency state.
  • One of the four files used for the NEPTUNE database has become corrupt.

With these facts in mind, answer the following questions:

  1. Which command would you use to rebuild the system databases on SYD-SQL-A? Answer.

    2. Use the following command to rebuild the system databases on the default instance of SYD-SQL-A: setup /Q /ACTION=REBUILDDATABASE /INSTANCENAME=MSSQLSERVER

    Hide the Answer.

  2. Which Transact-SQL statement can you use to check the state of the HOVERCRAFT database? Answer.

    Use the following command to check the current state of the HOVERCRAFT database: SELECT databasepropertyex ('HOVERCRAFT', 'Status');

    Hide the Answer.

  3. Under what conditions would you be able to perform an online file restore of the corrupted file of the NEPTUNE database? Answer.

    You can perform an online file restore of the corrupted file in the NEPTUNE database if you can perform a tail-log backup, the host instance is running SQL Server 2012 Enterprise edition, and the primary file group is online.
