NEW QUESTION # 407
You have a single availability set that contains two SQL Server on Azure Virtual Machines instances.
The instances were deployed by using an Azure Marketplace SQL Server 2019 Enterprise image that has the latest cumulative updates applied. The instances are configured as the nodes of a failover cluster instance (FCI) named FCI1.
You need to ensure that client applications can connect to FCI1. The solution must meet the following requirements:
* Provide an availability SLA
* Minimize costs.
What should you create?
Answer: D
Explanation:
Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why C is Correct: a distributed network name (DNN) resource is correct because it is the feature whose normal purpose matches the stated requirement. a distributed network name (DNN) resource is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The scenario wording points to that specific behavior: You need to ensure that client applications can connect to FCI1.
Why A is Wrong: a virtual network name (VNN) resource is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why B is Wrong: a Basic Azure Load Balancer is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
Why D is Wrong: an Azure Standard Load Balancer is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
NEW QUESTION # 408
HOTSPOT
You have an Azure SQL Database managed instance named sqldbmi1 that contains a database name Sales.
You need to initiate a backup of Sales.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the
answer area.
NOTE: Each correct selection is worth one point.

Section: [none]
Explanation:
Box 1: TO URL = 'https://storage1.blob.core.windows.net/blob1/Sales.bak'
Native database backup in Azure SQL Managed Instance.
You can backup any database using standard BACKUP T-SQL command:
BACKUP DATABASE tpcc2501

NEW QUESTION # 409
You plan to migrate on-premises Microsoft SQL Server databases to Azure.
You need to identify which deployment and resiliency options meet the following requirements:
* Support user-initiated backups.
* Support multiple automatically replicated instances across Azure regions.
* Minimize administrative effort to implement and maintain business continuity.
What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: SQL Server on Azure VMs
SQL Server on Azure Virtual Machines can take advantage of Automated Backup, which regularly creates backups of your database to blob storage. You can also manually use this technique.
Box 2: Active geo-replication
Geo-replication for services such as Azure SQL Database and Cosmos DB will create secondary replicas of your data across multiple regions. While both services will automatically replicate data within the same region, geo-replication protects you against a regional outage by enabling you to fail over to a secondary region.

NEW QUESTION # 411
You plan to develop a dataset named Purchases by using Azure Databricks. Purchases will contain the following columns:
ProductID
ItemPrice
LineTotal
Quantity
StoreID
Minute
Month
Hour
Year
Day
You need to store the data to support hourly incremental load pipelines that will vary for each StoreID. The solution must minimize storage costs.
How should you complete the code? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: .partitionBy
Example:
df.write.partitionBy( " y " , " m " , " d " )
mode(SaveMode.Append)
parquet( " /data/hive/warehouse/db_name.db/ " + tableName)
Box 2: ( " Year " , " Month " , " Day " , " Hour " , " StoreID " )
Box 3: .parquet( " /Purchases " )
Reference:
https://intellipaat.com/community/11744/how-to-partition-and-write-dataframe-in-spark-without-deleting-partitions-with-no-new-data Basic Concept: This question tests monitor, configure, and optimize database resources in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: Purchases will contain the following columns:
ProductID ItemPrice LineTotal Quantity StoreID Minute Month Hour Year Day You need to store the data to support hourly incremental load pipelines that will vary for each StoreID.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
