A database volume on a Dell PowerStore cluster has a Protection Policy that is applied with a single snapshot rule. The policy takes a snapshot every hour and retains them for 48 hours. The storage administrator must present a copy of the database volume to a test environment
Which action does the storage administrator take to meet this requirement?
- A . Restore the snapshot to a new test volume
- B . Create a thin clone of the database volume and map it to the test host
- C . Create a new snapshot policy for the test volume
- D . Create a snapshot of the database volume and map it to the test host
B
Explanation:
A thin clone is a writeable copy of a volume, which shares the same data blocks as the parent volume. This allows the administrator to provide a copy of the production database volume to the test environment without affecting the production data. It also allows to test the data without affecting the production data, and also it doesn’t require additional storage space.
Which encryption algorithm is used for SMB shares on Dell EMC Unity?
- A . AES-CCM
- B . AES128-GCM
- C . AES-CMAC
- D . HMAC-SHA256
B
Explanation:
This provides improved security and encryption traffic performance for SMB3 by changing the encryption algorithm from AES-CCM-128 to AESGCM-128.

What are differences between the Dell Unity XT 380F array and the Dell Unity XT 880F array?
- A . Dell Unity XT 380F has converged network adapter ports. Dell Unity XT 880F has embedded mezzanine ports.
- B . Dell Unity XT 380F supports dynamic storage pools. Dell Unity XT 880F does not support dynamic storage pools.
- C . Dell Unity XT 380F has embedded mezzanine ports. Dell Unity XT 880F has converged network adapter ports.
- D . Dell Unity XT 380F does not support dynamic storage pools. Dell Unity XT 880F supports dynamic storage pools.
A
Explanation:
The Dell Unity XT 380F array is equipped with converged network adapter (CNA) ports, while the Dell Unity XT 880F array features embedded mezzanine ports. These differences in port configurations reflect the varied performance and connectivity options available in different models of the Unity XT series.
