HOTSPOT
You have a server named Server1 that runs Windows Server 2012 R2. The volumes on Server1 are
configured as shown in the following table.
A new corporate policy states that backups must use Windows Azure Backup whenever possible.
You need to identify which backup methods you must use to back up Server1. The solution must use
Windows Azure Backup whenever possible.
Which backup type should you identify for each volume?
To answer, select the appropriate backup type for each volume in the answer area.

The answer isn’t correct, please see https://azure.microsoft.com/en-us/documentation/articles/backup-azure-backup-faq/
Volume1 = Windows Server Backup, because Azure doesn’t backup Bitlocker protected drives
Volume2 = Azure
Volume 3 + 4 = Windows Backup, because Azure only accepts fixed disks, no removable drives
agree:
Q11. What types of drives can I backup files and folders from?
A11. The following set of drives/volumes can’t be backup:
…
Bitlocker protected volumes: The volume must be unlocked before the backup can occur.
but some says so important statements is “use widnows azure whenewer possible” so theoretically there is posibility to unlcok the volume -> backup -> lock
http://www.aiotestking.com/microsoft/which-backup-type-should-you-identify-for-each-volume-2/
https://azure.microsoft.com/en-us/documentation/articles/backup-azure-backup-faq/ Clearly states BitLocker-protected drive volumes cannot be backed up. Nor can it back up removable media. So the correct answers (if the question is worded correctly) should be
Windows Server Backup
Windows Azure Backup
Windows Server Backup
Windows Server Backup
This answer is right, because we can unlock and lock a bitlocker drive.

the answer is right
Q12. What file and folder types can I back up from my server?
A12. The following types are supported:
Encrypted
Compressed
Sparse
Compressed + Sparse
Hard Links: Not supported, skipped
Reparse Point: Not supported, skipped
Encrypted + Compressed: Not supported, skipped
Encrypted + Sparse: Not supported, skipped
Compressed Stream: Not supported, skipped
Sparse Stream: Not supported, skipped
Answer is WRONG!
It should be…
Vol 1 – Windows Server Backup
Vol 2 – Windows Azure Backup
Vol 3 – Windows Server Backup
Vol 4 – Windows Server Backup
Here’s why….first – lets get Vol 3 & 4 out of the way. We can all agree that the Azure Backup FAQ says that they don’t backup removable disks unless it presents as a “local disk”. You can read that for yourself here: https://azure.microsoft.com/en-us/documentation/articles/backup-azure-backup-faq/ <- see Question 11.
Lets now focus on Vo1. It's bitlocker protected. Now look at Q11 again in the FAQ in the link I just posted. Here it is again edited for my point…
Q11. What types of drives can I backup files and folders from?
A11. The following set of drives/volumes can't be backup:
Bitlocker protected volumes: The volume must be unlocked before the backup can occur.
Read it carefully. "Must be unlocked before the backup can occur". Now…think about that. If it is unlocked it is no longer bitlocker protected. Azure Backup cannot backup a drive where bitlocker is in place.
To backup a bitlockered drive, you have to "work around" the bitlocker protection. Basically unprotecting your drive (making it like Volume2 in the image above), backing it up, then re-encrypting it. This is not "backing up a drive with bitlocker protection". It is backing up a drive "that's just had the bitlocker protection removed". <- see the difference?
tl:dr
"Hey TDAC – can you steal my car if it's locked?"
Me: "Sure can if you give me the keys."
You should be aware of some other limitations as well. Windows Azure Backup can’t be used when:
A non-NTFS volume is used
The drive type isn’t fixed
A volume is read-only
A volume is offline
A volume is on a network share
