Exam 312-49v10 topic 1 question 639 discussion

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.

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.

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 Medium blob is an outdated term and not a valid blob type in Azure Blob Storage.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.

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
