NEW QUESTION 1

You need to set up access to Azure SQL Database for Tier 7 and Tier 8 partners.
Which three actions should you perform in sequence? To answer, move the appropriate three actions from the list of actions to the answer area and arrange them in the correct order.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Tier 7 and 8 data access is constrained to single endpoints managed by partners for access Step 1: Set the Allow Azure Services to Access Server setting to Disabled
Set Allow access to Azure services to OFF for the most secure configuration.
By default, access through the SQL Database firewall is enabled for all Azure services, under Allow access to Azure services. Choose OFF to disable access for all Azure services.
Note: The firewall pane has an ON/OFF button that is labeled Allow access to Azure services. The ON setting allows communications from all Azure IP addresses and all Azure subnets. These Azure IPs or subnets might not be owned by you. This ON setting is probably more open than you want your SQL Database to be. The virtual network rule feature offers much finer granular control.
Step 2: In the Azure portal, create a server firewall rule Set up SQL Database server firewall rules
Server-level IP firewall rules apply to all databases within the same SQL Database server. To set up a server-level firewall rule:
In Azure portal, select SQL databases from the left-hand menu, and select your database on the SQL databases page.
On the Overview page, select Set server firewall. The Firewall settings page for the database server opens.
Step 3: Connect to the database and use Transact-SQL to create a database firewall rule
Database-level firewall rules can only be configured using Transact-SQL (T-SQL) statements, and only after you've configured a server-level firewall rule.
To setup a database-level firewall rule:
In Object Explorer, right-click the database and select New Query.
EXECUTE sp_set_database_firewall_rule N'Example DB Rule','0.0.0.4','0.0.0.4';
On the toolbar, select Execute to create the firewall rule. References:

NEW QUESTION 3

You are a data architect. The data engineering team needs to configure a synchronization of data between an on-premises Microsoft SQL Server database to Azure SQL Database.
Ad-hoc and reporting queries are being overutilized the on-premises production instance. The synchronization process must:
Perform an initial data synchronization to Azure SQL Database with minimal downtime Perform bi-directional data synchronization after initial synchronization
You need to implement this synchronization solution. Which synchronization method should you use?

• A. transactional replication
• B. Data Migration Assistant (DMA)
• C. backup and restore
• D. SQL Server Agent job
• E. Azure SQL Data Sync

Answer: E

Explanation:
SQL Data Sync is a service built on Azure SQL Database that lets you synchronize the data you select bi-directionally across multiple SQL databases and SQL Server instances.
With Data Sync, you can keep data synchronized between your on-premises databases and Azure SQL databases to enable hybrid applications.
Compare Data Sync with Transactional Replication

You need to configure data encryption for external applications. Solution:
1. Access the Always Encrypted Wizard in SQL Server Management Studio
2. Select the column to be encrypted
3. Set the encryption type to Randomized
4. Configure the master key to use the Windows Certificate Store
5. Validate configuration results and deploy the solution Does the solution meet the goal?

• A. Yes
• B. No

Answer: B

Explanation:
Use the Azure Key Vault, not the Windows Certificate Store, to store the master key.
Note: The Master Key Configuration page is where you set up your CMK (Column Master Key) and select the key store provider where the CMK will be stored. Currently, you can store a CMK in the Windows certificate store, Azure Key Vault, or a hardware security module (HSM).

NEW QUESTION 20

You manage a process that performs analysis of daily web traffic logs on an HDInsight cluster. Each of 250 web servers generates approximately gigabytes (GB) of log data each day. All log data is stored in a single folder in Microsoft Azure Data Lake Storage Gen 2.
You need to improve the performance of the process.
Which two changes should you make? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

• A. Combine the daily log files for all servers into one file
• B. Increase the value of the mapreduce.map.memory parameter
• C. Move the log files into folders so that each day’s logs are in their own folder
• D. Increase the number of worker nodes
• E. Increase the value of the hive.tez.container.size parameter

Answer: AC

Explanation:
A: Typically, analytics engines such as HDInsight and Azure Data Lake Analytics have a per-file overhead. If you store your data as many small files, this can negatively affect performance. In general, organize your data into larger sized files for better performance (256MB to 100GB in size). Some engines and applications might have trouble efficiently processing files that are greater than 100GB in size.
C: For Hive workloads, partition pruning of time-series data can help some queries read only a subset of the data which improves performance.
Those pipelines that ingest time-series data, often place their files with a very structured naming for files and folders. Below is a very common example we see for data that is structured by date:
DataSetYYYYMMDDdatafile_YYYY_MM_DD.tsv
Notice that the datetime information appears both as folders and in the filename. References:
