Microsoft Azure Architect Design (AZ-301) Practice Exam

In the scenario where application servers need to auto-upload data to Azure from branch offices, the ideal choice would be Azure Blob storage. Azure Blob storage is specifically designed for unstructured data storage and can handle large amounts of data. It is accessible over HTTP or HTTPS, making it a suitable choice for remote branch offices that need to upload data to the cloud. Azure Blob storage allows for efficient scaling, redundancy, and geographic availability, which is beneficial for branch offices with varying bandwidth. It also supports various access tiers, enabling cost-effective storage management based on how frequently data is accessed. Azure File Sync, while useful for syncing files and providing file shares in the cloud, is typically used for on-premises file servers rather than direct auto-uploads from application servers. An Azure Storage account, while essential for managing different types of storage services in Azure, does not specify the use case for application servers needing auto-upload. The Azure Site Recovery vault focuses on disaster recovery solutions rather than direct file uploads or data storage needs. Hence, for the described requirement, Azure Blob storage is the most suitable solution, enabling seamless data uploading and management from branch office application servers.
