QUESTION
A company plans to use Azure SQL Database to support a mission-critical application.
The application must be highly available without performance degradation during maintenance windows.
You need to implement the solution.
Which three technologies should you implement? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Premium service tier
B. Virtual machine Scale Sets
C. Basic service tier
D. SQL Data Sync
E. Always On availability groups
F. Zone-redundant configuration
Correct Answer: AEF
A: Premium/business critical service tier model that is based on a cluster of database engine processes. This
architectural model relies on a fact that there is always a quorum of available database engine nodes and has minimal
performance impact on your workload even during maintenance activities.
E: In the premium model, Azure SQL database integrates compute and storage on the single node. High availability in
this architectural model is achieved by replication of compute (SQL Server Database Engine process) and storage
(locally attached SSD) deployed in 4-node cluster, using technology similar to SQL Server Always On Availability
Groups.
F: Zone redundant configuration By default, the quorum-set replicas for the local storage configurations are created in
the same datacenter. With the introduction of Azure Availability Zones, you have the ability to place the different replicas
in the quorum-sets 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).
QUESTION
A company has a Microsoft Azure HDInsight solution that uses different cluster types to process and analyze data.
Operations are continuous.
Reports indicate slowdowns during a specific time window.
You need to determine a monitoring solution to track down the issue in the least amount of time.
What should you use?
A. Azure Log Analytics log search query
B. Ambari REST API
C. Azure Monitor Metrics
D. HDInsight .NET SDK
E. Azure Log Analytics alert rule query
Correct Answer: B
Ambari is the recommended tool for monitoring the health for any given HDInsight cluster.
Note: Azure HDInsight is a high-availability service that has redundant gateway nodes, head nodes, and ZooKeeper
nodes to keep your HDInsight clusters running smoothly. While this ensures that a single failure will not affect the
functionality of a cluster, you may still want to monitor cluster health so you are alerted when an issue does arise.
Monitoring cluster health refers to monitoring whether all nodes in your cluster and the components that run on them are
available and functioning correctly. Ambari is the recommended tool for monitoring utilization across the whole cluster.
The Ambari dashboard shows easily glanceable widgets that display metrics such as CPU, network, YARN memory,
and HDFS disk usage. The specific metrics shown depend on cluster type. The “Hosts” tab shows metrics for individual
nodes so you can ensure the load on your cluster is evenly distributed.
QUESTION
A company uses Azure SQL Database to store sales transaction data. Field sales employees need an offline copy of
the database that includes last year\\’s sales on their laptops when there is no internet connection available.
You need to create the offline export copy.
Which three options can you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Export to a BACPAC file by using Azure Cloud Shell, and save the file to an Azure storage account
B. Export to a BACPAC file by using SQL Server Management Studio. Save the file to an Azure storage account C. Export to a BACPAC file by using the Azure portal
D. Export to a BACPAC file by using Azure PowerShell and save the file locally
E. Export to a BACPAC file by using the SqlPackage utility
Correct Answer: BCE
You can export to a BACPAC file using the Azure portal.
You can export to a BACPAC file using SQL Server Management Studio (SSMS). The newest versions of SQL Server
Management Studio provide a wizard to export an Azure SQL database to a BACPAC file.
You can export to a BACPAC file using the SQLPackage utility.
Incorrect Answers:
D: You can export to a BACPAC file using PowerShell. Use the New-AzSqlDatabaseExport cmdlet to submit an export
database request to the Azure SQL Database service. Depending on the size of your database, the export operation
may take some time to complete. However, the file is not stored locally.
QUESTION
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains
a unique solution that might meet the stated goals. Some questions sets might have more than one correct solution,
while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not
appear in the review screen.
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 Deterministic
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
Correct Answer: B
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)
