From which storage platforms does a migration import data to a Dell PowerStore cluster?
- A . Dell EqualLogic PS series Unity, Dell Compellent SC Series, and PowerVault ME
- B . PowerMax. Dell EqualLogic PS senes Dell Compellent SC Series and Unity
- C . VNXe Unity Dell Compellent SC Series and Dell EqualLogic PS series
- D . Unity VNX2 Dell EqualLogic PS series and Dell Compellent SC Series
D
Explanation:
A migration import allows data to be transferred from an existing storage platform to a Dell PowerStore cluster. The platforms that support migration import to a Dell PowerStore cluster include Unity, VNX2, Dell EqualLogic PS series and Dell Compellent SC Series. These platforms are EMC storage systems, which are now owned by Dell Technologies.
A storage administrator is deploying a new Dell Unity XT 880F system. The system will be used over FC by several hosts running production databases. The system will also be used over iSCSI to several hosts running tesVdev workloads. The administrator wants to prevent the test/dev hosts from using more than 5000 IOPS
What Unity XT feature can be used for this configuration?
- A . Thin clones
- B . LUN masking
- C . Host I/O limits
- D . FASTVP
C
Explanation:
Dell Unity XT’s Host I/O limits feature allows you to set limits on IOPS for individual hosts connected over iSCSI. This can be used to restrict the test/dev hosts to a maximum of 5000 IOPS
What storage resources are affected with a refresh option on a Dell EMC PowerStore array?
- A . Thin clones and volumes only
- B . Snapshots, thin clones, and volumes
- C . Thin clones, volumes, and replicas
- D . Thin clones and snapshots only
Which are benefits of choosing the highest capacity flash drives when designing a Dell Unity XT All-Flash system?
- A . Enhances data security and system boot time
- B . Lowers physical space power and cooling requirements
- C . Decreases ware-leveling, performance and redundancy requirements
- D . Reduces maintenance and rebuild time
B
Explanation:
Choosing the highest capacity flash drives when designing a Dell Unity XT All-Flash system can provide several benefits, including lower physical space, power and cooling requirements. Additionally, higher capacity drives can also improve system boot time, reduce maintenance and rebuild time, and decrease wear-leveling, performance, and redundancy requirements.
How many fans in a Dell EMC PowerStore node can fail before it shuts down?
- A . 1
- B . 2
- C . 3
- D . 4
A
Explanation:
A node can tolerate a single fan module fault, and the surviving fans increase their speed to compensate for the faulted module. If two fan modules fault within the same node, the node performs a protective thermal shutdown. A protective thermal shutdown gracefully powers off the node, and any resource fails over to the surviving node

CORRECT TEXT
A customer has two Dell Unity arrays a Dell Unity 550F and a Dell Unity XT 480 They are undergoing a network refresh and would like to modernize to a 25 GbE network. The customer has asked the technical architect about adding 25 GbE network cards to the Unity systems Both systems have free slots
Which option should the technical architect recommend?
A All Unity and Unity XT systems support 25 GbE.
B. The Unity XT 480 supports a 25 GbE card but the Unity 550F does not support a 25 GbE card
C. The Unity 550F supports a 25 GbE card but the Unity XT 480 does not support a 25 GbE card
D. 25 GbE is not supported on Unity or Unity XT systems
Explanation:
The Unity XT 480 can be upgraded with the 25 GbE network cards, but the Unity 550F will not be able to support them and the customer will have to consider upgrading the Unity 550F to a newer model that supports 25 GbE.
Which tool can be used to migrate file data for Windows hosts form a legacy VNX array to a new Dell Unity XT array?
- A . Robocopy
- B . SANCopy
- C . rsync
