You have SQL Server on an Azure virtual machine that contains a database named DB1.
The database reports a CHECKSUM error.
You need to recover the database.
How should you complete the statements? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: SINGLE_USER
The specified database must be in single-user mode to use one of the following repair options.
Box 2: REPAIR_ALLOW_DATA_LOSS
REPAIR_ALLOW_DATA_LOSS tries to repair all reported errors. These repairs can cause some data loss.
Note: The REPAIR_ALLOW_DATA_LOSS option is a supported feature but it may not always be the best option for bringing a database to a physically consistent state. If successful, the REPAIR_ALLOW_DATA_LOSS option may result in some data loss. In fact, it may result in more data lost than if a user were to restore the database from the last known good backup.
Incorrect Answers:
REPAIR_FAST
Maintains syntax for backward compatibility only. No repair actions are performed.
Box 3: MULTI_USER
MULTI_USER

You have an Azure SQL Database instance named DatabaseA on a server named Server1.
You plan to add a new user named App1 to DatabaseA and grant App1 db_datacenter permissions. App1 will
use SQL Server Authentication.
You need to create App1. The solution must ensure that App1 can be given access to other databases by using
the same credentials.

Answer:
Explanation:
Section: [none]
Explanation:
Step 1: On the master database, run CREATE LOGIN [App1] WITH PASSWORD = 'p@aaW0rd!'
Logins are server wide login and password pairs, where the login has the same password across all databases.
Here is some sample Transact-SQL that creates a login:
CREATE LOGIN readonlylogin WITH password='1231!#ASDF!a';
You must be connected to the master database on SQL Azure with the administrative login (which you get from
the SQL Azure portal) to execute the CREATE LOGIN command.
Step 2: On DatabaseA, run CREATE USER [App1] FROM LOGIN [App1]
Users are created per database and are associated with logins. You must be connected to the database in
where you want to create the user. In most cases, this is not the master database. Here is some sample
Transact-SQL that creates a user:
CREATE USER readonlyuser FROM LOGIN readonlylogin;
Step 3: On DatabaseA run ALTER ROLE db_datareader ADD Member [App1]
Just creating the user does not give them permissions to the database. You have to grant them access. In the
Transact-SQL example below the readonlyuser is given read only permissions to the database via the
db_datareader role.
EXEC sp_addrolemember 'db_datareader', 'readonlyuser';

NEW QUESTION 98
You have an Azure Synapse Analytics Apache Spark pool named Pool1.
You plan to load JSON files from an Azure Data Lake Storage Gen2 container into the tables in Pool1. The structure and data types vary by file.
You need to load the files into the tables. The solution must maintain the source data types.
What should you do?
- A. Use a Conditional Split transformation in an Azure Synapse data flow.
- B. Use a Get Metadata activity in Azure Data Factory.
- C. Load the data by using the OPENROWSET Transact-SQL command in an Azure Synapse Analytics serverless SQL pool.
- D. Load the data by using PySpark.
Answer: C
Explanation:
Serverless SQL pool can automatically synchronize metadata from Apache Spark. A serverless SQL pool database will be created for each database existing in serverless Apache Spark pools.
Serverless SQL pool enables you to query data in your data lake. It offers a T-SQL query surface area that accommodates semi-structured and unstructured data queries.
To support a smooth experience for in place querying of data that's located in Azure Storage files, serverless SQL pool uses the OPENROWSET function with additional capabilities.
The easiest way to see to the content of your JSON file is to provide the file URL to the OPENROWSET function, specify csv FORMAT.

Box 1: Column encryption Key
Always Encrypted uses two types of keys: column encryption keys and column master keys. A column
encryption key is used to encrypt data in an encrypted column. A column master key is a key-protecting key
that encrypts one or more column encryption keys.
Incorrect Answers:
TDE encrypts the storage of an entire database by using a symmetric key called the Database Encryption Key
(DEK).
Box 2: Deterministic
Always Encrypted is a feature designed to protect sensitive data, such as credit card numbers or national
identification numbers (for example, U.S. social security numbers), stored in Azure SQL Database or SQL
Server databases. Always Encrypted allows clients to encrypt sensitive data inside client applications and never
reveal the encryption keys to the Database Engine (SQL Database or SQL Server).
Always Encrypted supports two types of encryption: randomized encryption and deterministic encryption.
Deterministic encryption always generates the same encrypted value for any given plain text value. Using
deterministic encryption allows point lookups, equality joins, grouping and indexing on encrypted columns.
Incorrect Answers:
* Randomized encryption uses a method that encrypts data in a less predictable manner. Randomized
encryption is more secure, but prevents searching, grouping, indexing, and joining on encrypted columns.
* Transparent data encryption (TDE) helps protect Azure SQL Database, Azure SQL Managed Instance, and
Azure Synapse Analytics against the threat of malicious offline activity by encrypting data at rest. It performs
real-time encryption and decryption of the database, associated backups, and transaction log files at rest
without requiring changes to the application.

NEW QUESTION 101
You have an Azure SQL database named DB1.
You need to ensure that DB1 will support automatic failover without data loss if a datacenter fails. The solution must minimize costs.
Which deployment option and pricing tier should you configure?
- A. Azure SQL Database Standard
- B. Azure SQL Database managed instance Business Critical
- C. Azure SQL Database serverless
- D. Azure SQL Database Premium
Answer: D
Explanation:
Section: [none]
Explanation:
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical database to different availability zones in the same region. To eliminate a single point of failure, the control ring is also duplicated across multiple zones as three gateway rings (GW). The routing to a specific gateway ring is controlled by Azure Traffic Manager (ATM). Because the zone redundant configuration in the Premium or Business Critical service tiers does not create additional database redundancy, you can enable it at no extra cost. By selecting a zone redundant configuration, you can make your Premium or Business Critical databases resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes to the application logic. You can also convert any existing Premium or Business Critical databases or pools to the zone redundant configuration.
Incorrect Answers:
C. This feature is not available in SQL Managed Instance.

What should you implement to meet the disaster recovery requirements for the PaaS solution?
- A. Availability Zones
- B. failover groups
- C. geo-replication
- D. Always On availability groups
Answer: B
Explanation:
Scenario: In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with minimal downtime. The solution must provide automatic failover.
The auto-failover groups feature allows you to manage the replication and failover of a group of databases on a server or all databases in a managed instance to another region. It is a declarative abstraction on top of the existing active geo-replication feature, designed to simplify deployment and management of geo-replicated databases at scale. You can initiate failover manually or you can delegate it to the Azure service based on a user-defined policy.
The latter option allows you to automatically recover multiple related databases in a secondary region after a catastrophic failure or other unplanned event that results in full or partial loss of the SQL Database or SQL Managed Instance availability in the primary region.

You have an Azure SQL database.
You discover that the plan cache is full of compiled plans that were used only once.
You run the select * from sys.database_scoped_configurationsTransact-SQL command and
receive the results shown in the following table.
You need relieve the memory pressure.
What should you configure?
- A. QUERY_OPTIMIZER_HOTFIXES
- B. OPTIMIZE_FOR_AD_HOC_WORKLOADS
- C. ACCELERATED_PLAN_FORCING
- D. LEGACY_CARDINALITY_ESTIMATION
Answer: B
Explanation:
Section: [none]
Explanation:
OPTIMIZE_FOR_AD_HOC_WORKLOADS = { ON | OFF }
Enables or disables a compiled plan stub to be stored in cache when a batch is compiled for the first time. The
default is OFF. Once the database scoped configuration OPTIMIZE_FOR_AD_HOC_WORKLOADS is enabled
for a database, a compiled plan stub will be stored in cache when a batch is compiled for the first time. Plan
stubs have a smaller memory footprint compared to the size of the full compiled plan.
Incorrect Answers:
A: LEGACY_CARDINALITY_ESTIMATION = { ON | OFF | PRIMARY }
Enables you to set the query optimizer cardinality estimation model to the SQL Server 2012 and earlier version
independent of the compatibility level of the database. The default is OFF, which sets the query optimizer
cardinality estimation model based on the compatibility level of the database.
B: QUERY_OPTIMIZER_HOTFIXES = { ON | OFF | PRIMARY }
Enables or disables query optimization hotfixes regardless of the compatibility level of the database. The default
is OFF, which disables query optimization hotfixes that were released after the highest available compatibility
level was introduced for a specific version (post-RTM).
