QUESTION 76
You administer a Microsoft SQL Server 2012 database.
You configure Transparent Data Encryption (TDE) on the Orders database by using the following statements:
CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘MyPassword1!’
CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = ‘TDE Certificate’;
BACKUP CERTIFICATE TDE_Certificate TO FILE = ”d:\TDE_Certificate.cer’ WITH PRIVATE KEY (FILE = ‘D:\TDE_Certificate.key’,
ENCRYPTION BY PASSWORD = ‘MyPassword1!’);
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
ALTER DATABASE Orders SET ENCRYPTION ON;
You attempt to restore the Orders database and the restore fails.
You copy the encryption file to the original location.
A hardware failure occurs and so a new server must be installed and configured.
After installing SQL Server to the new server, you restore the Orders database and copy the encryption files to their original location. However, you are unable to access the database.
You need to be able to restore the database.
Which Transact-SQL statement should you use before attempting the restore?
A. ALTER DATABASE Master SET ENCRYPTION OFF;
B. CREATE CERTIFICATE TDE_Certificate FROM FILE = ‘d:\TDE_Certificate.cer’ WITH PRIVATE KEY (FILE = ‘D:\TDE_Certificate.key’,
DECRYPTION BY PASSWORD = ‘MyPassword1!’);
C. CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = ‘TDE Certificate’; USE Orders; CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
D. CREATE CERTIFICATE TDE_Certificate FROM FILE = ‘d:\TDE_Certificate.cer’;
Answer: B
Explanation:
The CREATE CERTIFICATE command adds a certificate to a database in SQL Server.
Creating a certificate from a file
The following example creates a certificate in the database, loading the key pair from files.
Code
Copy
USE AdventureWorks2012;
CREATE CERTIFICATE Shipping11
FROM FILE = ‘c:\Shipping\Certs\Shipping11.cer’
WITH PRIVATE KEY (FILE = ‘c:\Shipping\Certs\Shipping11.pvk’, DECRYPTION BY PASSWORD = ‘sldkflk34et6gs%53#v00’);

AccountTransaction.AccountCode REBUILD
D. CREATE INDEX IDXAccountTransactionAccountCode ON
AccountTransaction.AccountCode WITH DROP EXISTING
Answer: A
Explanation:Reorganize: This option is more lightweight compared to rebuild. It runs through the leaf level of the index, and as it goes it fixes physical ordering of pages and also compacts pages to apply any previously set fillfactor settings. This operation is always online, and if you cancel it then it’s able to just stop where it is (it doesn’t have a giant operation to rollback).

QUESTION 83
You administer a Microsoft SQL Server 2012 failover cluster.
You need to ensure that a failover occurs when the server diagnostics returns query_processing error.
Which server configuration property should you set?
A. SqlOumperDumpFlags
B. FailureConditionLevel
C. HealthCheckTimeout
D. SqlDumperDumpPath
Answer: B
Explanation:
Use the FailureConditionLevel property to set the conditions for the Always On Failover Cluster Instance (FCI) to fail over or restart.
The failure conditions are set on an increasing scale. For levels 1-5, each level includes all the conditions from the previous levels in addition to its own conditions.
Note: The system stored procedure sp_server_diagnostics periodically collects component diagnostics on the SQL instance. The diagnostic information that is collected is surfaced as a row for each of the following components and passed to the calling thread.
1. system
2. resource
3. query process
4. io_subsystem
5. events
The system, resource, and query process components are used for failure detection.
The io_subsytem and events components are used for diagnostic purposes only.

QUESTION 84
You are the administrator of a Microsoft SQL Server 2012 server.
Some applications consume significant resources. You need to manage the server workload by restricting resource-intensive applications.
You need to dynamically limit resource consumption.
What should you do?
A. Configure Resource Pools, Workload Groups, and Classifier Function, and then enable the Resource Governor
B. Set up Service Broker to ensure that application are not allowed to consume more than the specified amount of resource
C. Create a new rule for each application that sets the resource limit allowed
D. Create a new plan Guide with a Scope Type of sql and define the resource limits for each application
Answer: A
Explanation:
In the SQL Server Resource Governor, a resource pool represents a subset of the physical resources of an instance of the Database Engine. Resource Governor enables you to specify limits on the amount of CPU, physical IO, and memory that incoming application requests can use within the resource pool. Each resource pool can contain one or more workload groups. When a session is started, the Resource Governor classifier assigns the session to a specific workload group, and the session must run using the resources assigned to the workload group.

QUESTION 89
You administer a Microsoft SQL Server 2012 database named Orders.
Orders contains a table named OrderShip that is defined as follows:
A NULL value represents a domestic order. Ninety percent of the values in CountryCode are NULL.
Customers require a procedure that will return orders for all customers from a specified country.
You create a new procedure:
Performance on this procedure is slow.
You need to alter the schema to optimize this query.
Objects created must use a minimum amount of resources.
Which Transact-SQL statement should you use?
A. CREATE NONCLUSTERED INDEX IX_CountryCode ON Ordership (CountryCode) WHERE CountryCode IS NOT NULL
B. CREATE STATISTICS ST_CountryCode ON OrderShip (CountryCode) WHERE CountryCode IS NOT NULL
C. CREATE CLUSTERED INDEX IX_CountryCode ON OrderShip (CountryCode)
D. CREATE INDEX IX_CountryCode ON OrderShip (CustomerID) WHERE CountryCode IS NOT NULL
Answer: B
Explanation:
Here creating statistics is relevant. The CREATE STATISTICS command creates query optimization statistics on one or more columns of a table, an indexed view, or an external table. For most queries, the query optimizer already generates the necessary statistics for a high-quality query plan; in a few cases, you need to create additional statistics with CREATE STATISTICS or modify the query design to improve query performance.
https://docs.microsoft.com/en-us/sql/t-sql/statements/create-statistics-transact-sql
QUESTION 90
You administer a Microsoft SQL Server 2012 database.
The database is currently configured to log ship to a secondary server.
You are preparing to cut over to the secondary server by stopping log-shipping and bringing the secondary database online.
You want to perform a tail-log backup.
You need to leave the primary database in a restoring state.
Which option of the BACKUP LOG command should you use?
A. NO_TRUNCATE
B. NORECOVERY
C. STANDBY
D. FORMAT
Answer: B
Explanation:
It is recommended that you take a tail-log backup in the following scenarios:
* If the database is online and you plan to perform a restore operation on the database, begin by backing up the tail of the log. To avoid an error for an online database, you must use the … WITH NORECOVERY option of the BACKUP Transact-SQL statement.
Note: A tail-log backup captures any log records that have not yet been backed up (the tail of the log) to prevent work loss and to keep the log chain intact. Before you can recover a SQL Server database to its latest point in time, you must back up the tail of its transaction log. The tail-log backup will be the last backup of interest in the recovery plan for the database.
