DRAG DROP
You are developing the following applications. All applications will be hosted in Azure and data will be stored using Azure storage.
All data must be stored using the binary large object (blob) hot storage tier.
You need to select the blob storage type for each application.
Which blob storage types should you use? To answer, drag the appropriate blob types to the correct applications. Each blob type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Explanation:
Box 1 Logging: append blob
An append blob is comprised of blocks and is optimized for append operations. When you modify an append blob, blocks are added to the end of the blob only, via the Append Block operation.
Box 2 VM Manager: block blob
Block blobs let you upload large blobs efficiently.
Box 3: Accounting: page blob
Page blobs are a collection of 512-byte pages optimized for random read and write operations.

Johny noted correctly:
* Block blobs store text and binary data, up to about 4.7 TB. Block blobs are made up of blocks of data that can be managed individually.
* Append blobs are made up of blocks like block blobs, but are optimized for append operations. Append blobs are ideal for scenarios such as logging data from virtual machines.
* Page blobs store random access files up to 8 TB in size. Page blobs store virtual hard drive (VHD) files and serve as disks for Azure virtual machines. For more information about page blobs, see Overview of Azure page blobs
Johnny is correct.
