                                              NEW QUESTION # 290
                                              You need to apply 20 built-in Azure Policy definitions to all new and existing Azure SQL Database deployments in an Azure subscription. The solution must minimize administrative effort.
                                              Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

                                              Answer:

                                              Explanation:

                                              Explanation

                                              Step 1: Create an Azure Policy Initiative
                                              The first step in enforcing compliance with Azure Policy is to assign a policy definition. A policy definition defines under what condition a policy is enforced and what effect to take.
                                              With an initiative definition, you can group several policy definitions to achieve one overarching goal. An initiative evaluates resources within scope of the assignment for compliance to the included policies.
                                              Step 2: Create an Azure Policy Initiative assignment
                                              Assign the initiative definition you created in the previous step.
                                              Step 3: Run Azure Policy remediation tasks
                                              To apply the Policy Initiative to the existing SQL databases.

                                              NEW QUESTION # 292
                                              You have eight on-premises servers that have Microsoft SQL Server 2022 installed. Each server contains multiple databases.
                                              You plan to migrate the on-premises databases to Azure.
                                              You need to analyze the servers to identify which Azure SQL services can be used to host the databases.
                                              Which two tools can you use? Each correct answer presents a complete solution.
                                              NOTE: Each correct selection is worth one point.

                                              Answer: B,E

                                              Explanation:
                                              [A] The Data Migration Assistant (DMA) can be used to identify which Azure SQL services are suitable for hosting your databases when migrating from SQL Server 2022 to Azure. DMA assesses your on-premises SQL Server databases and provides recommendations on whether they are compatible with Azure SQL Database or Azure SQL Managed Instance. It identifies potential migration blockers and compatibility issues, helping you choose the appropriate Azure SQL service.
                                              [D] Azure Migrate can be used to identify which Azure SQL services are suitable for hosting your migrated databases. It assesses on-premises SQL Server databases for migration readiness, providing recommendations on target Azure SQL service options like Azure SQL Database (single database or elastic pool), Azure SQL Managed Instance, and SQL Server on Azure VMs.
                                              Azure Migrate also helps with performance-based sizing and cost estimations for running the databases in Azure.

                                              NEW QUESTION # 293
                                              You are designing an enterprise data warehouse in Azure Synapse Analytics that will store website traffic analytics in a star schema.
                                              You plan to have a fact table for website visits. The table will be approximately 5 GB.
                                              You need to recommend which distribution type and index type to use for the table. The solution must provide the fastest query performance.
                                              What should you recommend? To answer, select the appropriate options in the answer area.
                                              NOTE: Each correct selection is worth one point.

                                              Answer:

                                              Explanation:

                                              Explanation:

                                              Box 1: Hash
                                              Consider using a hash-distributed table when:
                                              The table size on disk is more than 2 GB.
                                              The table has frequent insert, update, and delete operations.
                                              Box 2: Clustered columnstore
                                              Clustered columnstore tables offer both the highest level of data compression and the best overall query performance.

                                              NEW QUESTION # 294
                                              You have an Azure subscription.
                                              You need to deploy an Azure SQL managed instance by using an Azure Resource Manager (ARM) template.
                                              The solution must meet the following requirements:
                                              The SQL managed instance must be assigned a unique identity.
                                              The SQL managed instance must be available in the event of an Azure datacenter outage.
                                              How should you complete the template? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
