You plan to deploy 10 applications to Azure. The applications will be deployed to two Azure Kubernetes Service (AKS) clusters. Each cluster will be deployed to a separate Azure region.The application deployment must meet the following requirements:Ensure that the applications remain available if a single AKS cluster fails.Ensure that the connection traffic over the internet is encrypted by using SSL without having to configureSSL on each container.Which service should you include in the recommendation?
Answer(s): A
Azure Front Door supports SSL.Azure Front Door, which focuses on global load-balancing and site acceleration, and Azure CDN Standard, which offers static content caching and acceleration. The new Azure Front Door brings together security with CDN technology for a cloud-based CDN with threat protection and additional capabilities.

HOTSPOT (Drag and Drop is not supported)You have an Azure web app named App1 and an Azure key vault named KV1.App1 stores database connection strings in KV1.App1 performs the following types of requests to KV1:GetListWrapDeleteUnwrapBackupDecryptEncryptYou are evaluating the continuity of service for App1.You need to identify the following if the Azure region that hosts KV1 becomes unavailable:To where will KV1 fail over?During the failover, which request type will be unavailable?What should you identify? To answer, select the appropriate options in the answer area.Note: Each correct selection is worth one point.Hot Area:
Box 1: A service in the paired regionThe contents of your key vault are replicated within the region and to a secondary region at least 150 miles away, but within the same geography to maintain high durability of your keys and secrets.Regions are paired for cross-region replication based on proximity and other factors.Box 2: DeleteDuring failover, your key vault is in read-only mode. Requests that are supported in this mode are:List certificatesGet certificatesList secretsGet secretsList keysGet (properties of) keysEncryptDecryptWrapUnwrapVerifySignBackup

DRAG DROP (Drag and Drop is not supported)Your company identifies the following business continuity and disaster recovery objectives for virtual machines that host sales, finance, and reporting applications in the company’s on-premises data center:The sales application must be able to fail over to a second on-premises data center.The reporting application must be able to recover point-in-time data at a daily granularity. The RTO is eight hours.The finance application requires that data be retained for seven years. In the event of a disaster, the application must be able to run from Azure. The recovery time objective (RTO) is 10 minutes.You need to recommend which services meet the business continuity and disaster recovery objectives. The solution must minimize costs.What should you recommend for each application? To answer, drag the appropriate services to the correct applications. Each service 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.Note: Each correct selection is worth one point.Select and Place:
Box 1: Azure Site RecoveryAzure Site RecoveryCoordinates virtual-machine and physical-server replication, failover, and fullback. DR solutions have low Recovery point objectives; DR copy can be behind by a few seconds/minutes. DR needs only operational recovery data, which can take hours to a day. Using DR data for long-term retention is not recommended because of the fine-grained data capture. Disaster recovery solutions have smaller Recovery time objectives because they are more in sync with the source.Remote monitor the health of machines and create customizable recovery plans.Box 2: Azure Site Recovery and Azure BackupBackup ensures that your data is safe and recoverable while Site Recovery keeps your workloads available when/if an outage occurs.Box 3: Azure Backup onlyAzure BackupBacks up data on-premises and in the cloudHave wide variability in their acceptable Recovery point objective. VM backups usually one day while database backups as low as 15 minutes.Backup data is typically retained for 30 days or less. From a compliance view, data may need to be saved for years. Backup data is ideal for archiving in such instances. Because of a larger Recovery point objective, the amount of data a backup solution needs to process is usually much higher, which leads to a longer Recovery time objective.

You need to design a highly available Azure SQL database that meets the following requirements:Failover between replicas of the database must occur without any data loss.The database must remain available in the event of a zone outage.Costs must be minimized.Which deployment option should you use?
Answer(s): B
Correct:* Azure SQL Database Business Critical (if Premium and Serverless not options, as Business Critical is more expensive)* Azure SQL Database Premium (if not Database Serverless is an option. Premium is more expensive than Serverless)* Azure SQL Database ServerlessOrder of cost:1. Azure SQL Database Serverless (least expensive)2. Azure SQL Database Premium3. Azure SQL Database Business Critical (most expensive)Incorrect:* Azure SQL Database Basic* Azure SQL Database Hyperscale* Azure SQL Database Standard* Azure SQL Managed Instance Business Critical* Azure SQL Managed Instance General PurposeNote on correct answers:* Azure SQL Database PremiumAzure SQL Database Premium tier supports multiple redundant replicas for each database that are automatically provisioned in the same datacenter within a region. This design leverages the SQL Server AlwaysON technology and provides resilience to server failures with 99.99% availability SLA and RPO=0.With the introduction of Azure Availability Zones, we are happy to announce that SQL Database now offers built-in support of Availability Zones in its Premium service tier.* Azure SQL Database ServerlessNow your new and existing serverless Azure SQL Databases allow for zone redundant configuration. This feature utilizes Azure Availability Zones to replicate databases across multiple physical locations within an Azure region. By selecting zone redundancy, you can make your serverless databases resilient to a much larger set of failures, including catastrophic datacenter outages – without any changes of the application logic.Note: The SQL Database serverless compute tier optimizes price-performance and simplifies performance management for single databases with intermittent, unpredictable usage by auto-scaling compute and billing for compute used per second.Serverless is a compute tier for single databases in Azure SQL Database that automatically scales compute based on workload demand and bills for the amount of compute used per second. The serverless compute tier also automatically pauses databases during inactive periods when only storage is billed and automatically resumes databases when activity returnsNote on incorrect answers:* Azure SQL Database BasicNeed Premium for Availability Zones.* Azure SQL Database HyperscaleHyperscale is more expensive than Premium/ Database Serverless.* Azure SQL Managed Instance Business CriticalAzure SQL Managed Instance Business Critical is more expensive.* Azure SQL Managed Instance General PurposeZone redundant configuration that is free on Azure SQL Premium is not available on Azure SQL Managed Instance.Note: There are two high availability architectural models:* Standard availability model that is based on a separation of compute and storage. It relies on high availability and reliability of the remote storage tier. This architecture targets budget-oriented business applications that can tolerate some performance degradation during maintenance activities.* Premium availability model that is based on a cluster of database engine processes. It relies on the fact that there is always a quorum of available database engine nodes. This architecture targets mission-critical applications with high IO performance, high transaction rate and guarantees minimal performance impact to your workload during maintenance activities.Note: Zone-redundant configuration for the general purpose service tier is offered for both serverless and provisioned compute. This configuration utilizes Azure Availability Zones to replicate databases across multiple physical locations within an Azure region.By selecting zone-redundancy, you can make yournew and existing serverless and provisioned generalpurpose single databases and elastic pools resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes of the application logic.
