Scenario: App1 has the following data requirements:Each instance will write data to a data store in the same availability zone as the instance. Data written by any App1 instance must be visible to all App1 instances. Azure Cosmos DB: Each partition across all the regions is replicated. Each region contains all the data partitions of an Azure Cosmos container and can serve reads as well as serve writes when multiregion writes is enabled.Incorrect Answers:B, D: GZRS protects against failures. Geo-redundant storage (with GRS or GZRS) replicates your data to another physical location in the secondary region to protect against regional outages. However, that data is available to be read only if the customer or Microsoft initiates a failover from the primary to secondary region. C: Active geo-replication is designed as a business continuity solution that lets you perform quick disaster recovery of individual databases in case of a regional disaster or a large scale outage. Once georeplication is set up, you can initiate a geo-failover to a geo-secondary in a different Azure region. The geo-failover is initiated programmatically by the application or manually by the user. Reference:https://docs.microsoft.com/en-us/azure/cosmos-db/high-availability

Box 1: Azure FilesScenario: App2 has the following file storage requirements:   Save files to an Azure Storage account. Replicate files to an on-premises location. Ensure that on-premises clients can read the files over the LAN by using the SMB protocol. Box 2: Azure File SyncUse Azure File Sync to centralize your organization's file shares in Azure Files, while keeping the flexibility, performance, and compatibility of an on-premises file server. Azure File Sync transforms Windows Server into a quick cache of your Azure file share. You can use any protocol that's available on Windows Server to access your data locally, including SMB, NFS, and FTPS. You can have as many caches as you need across the world. Reference: https://docs.microsoft.com/en-us/azure/storage/file-sync/file-sync-deployment-guide  

Directory synchronization between Azure Active Directory (Azure AD) and corp.fabrikam.com must not be affected by a link failure between Azure and the on-premises network. (This requires domain controllers in Azure). Users on the on-premises network must be able to authenticate to corp.fabrikam.com if an Internet link fails. (This requires domain controllers on-premises).
