You are the administrator of your company's ONTAP 9.7 storage system. Your system hosted CIFS shares in your Active Directory environment for several years without any problems. Suddenly users report to you that they can no longer access their CIFS shares.
What is the reason for this problem? (Choose the best answer.)
The reason users can no longer access their CIFS shares is likely because the user account used to join the SMB server to the Active Directory expired. In an environment where CIFS shares are authenticated against Active Directory, the SMB server depends on a valid AD account to facilitate those connections. If this account expires, authentication to the shares will fail, resulting in users being unable to access them.
Correct answer is D. deally, if the time difference between the storage system and the DC is greater than 5 minutes, only then a CIFS authentication failure will occur. https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_determine_if_a_Windows_Domain_Controller_is_a_suitable_NTP_server_for_Data_ONTAP_8_and_later
D 100% agreed. All kinds of connection/authentication issues can occur with time not synced.
D is the good answer because all users report...., no all users can be expired at the same time
