Which user accounts will be synchronized?

An organization deploys an Office 365 tenant.
User accounts must be synchronized to Office 365 by using the Windows Azure Active Directory Sync tool.
You have the following password policies:
– Passwords for the on-premises Active Directory Domain Services (AD DS) user accounts are at least six characters long.
– Passwords for Office 365 user accounts are at least eight characters long.
You need to ensure that the user accounts will be synchronized. Which user accounts will be synchronized?

A.
All user accounts

B.
No user accounts

C.
User accounts with a password length of at least 8 characters

D.
User accounts with a password length of at least 14 characters

Explanation:

After deploying ADFS tenant password policies are handled by the local Active Directory Environment, and not Office 365 Azure. All users will be synchronized and
will utilize the AD DS six character long password policy.

When you enable password sync, the password complexity policies configured in the on-premises Active Directory override any complexity policies that may be
defined in the cloud for synchronized users. This means any password that is valid in the customer’s on-premises Active Directory environment can be used for
accessing Azure AD services.
As synchronization copies users info from local AD to Azure office 365 AD. 6 characters “local” will be accepted within 8 characters”cloud” Its true that After
deploying ADFS tenant password policies are handled by the local Active Directory Environment, and not Office 365 Azure, however. This is not the case in this
question! its not ADFS Also, my understanding that old DirSync doesn’t synchronize passwords from ADDS to Azure AD. only the new Azure Active Directory Sync
AADS.
