You are designing a plan for migrating Virtual Hard Disks (VHDs) and video files to Windows Azure Storage.
The VHDs must be optimized for random read/write operation.
The video files must be optimized for sequential access.
You need to recommend storage types for storing the VHDs and video files.
Which two storage types should you recommend? (Each correct answer presents part of the solution. Choose two.) streaming. Page blobs, which are optimized for random read/write operations and which provide the ability to write to a range of bytes in a blob. After you create or change the server image, you are ready to upload the as a template to create VM role instances.
A.
Store VHDs in Windows Azure page blob storage.
B.
Store VHDs in Windows Azure block blob storage.
C.
Store video files in Windows Azure page blob storage.
D.
Store video files in Windows Azure block blob storage.
Explanation:
You can store text and binary data in either of two types of blobs: Block blobs, which are optimized for
.vhd file that contains the image data to Windows Azure. There are two opportunities for uploading VHDs to
Windows Azure. When you initially create a VM role, you upload a base VHD to Windows Azure, which is used
Answer is correct:
Page blobs are comprised of 512-byte pages that are optimized for random read and write operations. Writes happen in place and are immediately committed. Page blobs are good for VHDs in Azure VMs and other files that have frequent, random access.
Block blobs are perfect for text files, images, and videos.
