                                              NEW QUESTION # 66
                                              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 question 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 have an Azure SQL database named Sales.
                                              You need to implement disaster recovery for Sales to meet the following requirements:
                                              * During normal operations, provide at least two readable copies of Sales.
                                              * Ensure that Sales remains available if a datacenter fails.
                                              Solution: You deploy an Azure SQL database that uses the Business Critical service tier and Availability Zones.
                                              Does this meet the goal?

                                              Answer: A

                                              Explanation:
                                              Explanation
                                              Premium and Business Critical service tiers leverage the Premium availability model, which integrates compute resources (sqlservr.exe process) and storage (locally attached SSD) on a single node. High availability is achieved by replicating both compute and storage to additional nodes creating a three to four-node cluster.
                                              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).

                                              NEW QUESTION # 67
                                              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.
