You need to recommend a solution that meets the security requirements for the mailbox
databases. What should you include in the recommendation?
A.
Resilient File System (ReFS)
B.
Transparent Data Encryption (TDE)
C.
BitLocker Drive Encryption (BitLocker)
D.
Encrypting Files System (EFS)
So what are the actual security requirements?
ReFS is actually RECOMMENDED for Exchange 2016 Database Volumes.
Transparent Data Encryption is more related to SQL (I think)
BitLocker Drive Encryption is more related to Physical Servers (which in most cases are not used any more)
Encrypted File System is kinda old technology (I wouldn’t bother)
So depending on the Requirements we would expect ReFS for virtual server configuration or BitLocker for physical servers
Yes, You are right.
REQ: Exchange Server mailbox databases must be encrypted while at rest.
Only EFS & BitLocker provide encryption (TDE is related to SQL) and Exchange does not support EFS, so the correct answer is C.
