Frank, a cloud administrator in his company, needs to take backup of the OS disks of two Azure VMs that store business-critical data. Which type of Azure blob storage can he use for this purpose?
Frank, a cloud administrator in his company, needs to take backup of the OS disks of two Azure VMs that store business-critical data. Which type of Azure blob storage can he use for this purpose?
Frank should use Page blob for backing up the OS disks of Azure VMs. Page blobs are specifically designed to handle random read/write operations, which makes them ideal for storing virtual hard disks (VHDs) used by Azure VMs. They are well-suited for scenarios involving frequent and random read/write operations, such as OS disks, and support large data files efficiently. The other types of blob storage (Append blobs and Block blobs) are not designed for this purpose, with Append blobs being used for log data and Block blobs for text and binary data without random read/write support.
he can use Azure Blob Storage. Among the types of blobs available in Azure Blob Storage, Page blob is the most suitable for storing OS disks, as they support random read/write operations and can handle large data files efficiently. Therefore, the correct option is D. Append blob is designed for appending data to an existing blob, such as log data, and is not suitable for storing OS disks. Medium blob is an outdated term and not a valid blob type in Azure Blob Storage. Block blob is designed for storing text and binary data as blocks and is commonly used for storing files and data objects. However, it is not suitable for storing OS disks, as it does not support random read/write operations.
correct
EC Council v10 book: Page Block - They are used for storing the backup copies of the virtual hard disks (VHDs) of Azure VMs
sorry for the typo... it's BLOB, not block
Page blobs are intended for random read-write operations and cannot be used to store the operating system disk of a virtual machine. Hence, option D (Page blob) is not a suitable choice for Frank's requirement
D. Page blob Frank can use Page blobs in Azure blob storage to take backups of the OS disks of the Azure VMs. Page blobs are optimized for representing virtual hard disk (VHD) files and are commonly used to store OS and data disks associated with Azure Virtual Machines. They allow you to perform tasks like snapshots, incremental backups, and cloning of disks.
D. Page blob Page blobs are optimized for random read and write operations and are ideal for storing virtual machine disks, including operating system disks and data disks. They are suitable for scenarios where frequent read and write operations occur, making them the best choice for VM backups in Azure.
