NEW QUESTION 37
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. Create a thin clone of the database volume and map it to the test host
• B. Create a new snapshot policy for the test volume
• C. Create a snapshot of the database volume and map it to the test host
• D. Restore the snapshot to a new test volume

Answer: A

Explanation:
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.

Answer: A

 

NEW QUESTION 45
A Dell EMC SC Series customer has purchased the Storage Optimization bundle and wants to ensure that Data Progression works efficiently.
Which daily snapshot expiration period conforms to best practice when using Data Progression?

• A. 24 hours
• B. 48 hours
• C. 25 hours
• D. 72 hours

Answer: C

 

NEW QUESTION 46
What occurs immediately before the write is acknowledged to the host in a Dell PowerStore 1000T?

• A. I/O is saved within the node DRAM memory
• B. The peer node is updated
• C. Data is passed through the deduplication and compression logic
• D. Information is stored on the nonvolatile media of the NVRAM drives

Answer: B

 

NEW QUESTION 47
What is one key difference between deduplication on Dell PowerStore and Dell Unity?

• A. Unity data reduction cannot be disabled
• B. Deduplication block size is smaller on PowerStore than on Unity
• C. Deduplication block size is larger on PowerStore than on Unity
• D. Unity has no deduplication function

Answer: B

Explanation:
Explanation
Deduplication is a feature that reduces storage capacity usage by eliminating duplicate data. PowerStore and Unity both have deduplication function, but one key difference is the size of the deduplication block.
PowerStore uses a smaller block size which allows for a higher level of granularity and more efficient deduplication. On the other hand, Unity uses a larger block size which is less granular, but it is still efficient for large sequential data workloads.

 

NEW QUESTION 48
A customer must protect file storage resources through asynchronous replication to other Dell Unity XT systems in different locations.
What is the maximum number of remote systems that can be configured?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: B

Explanation:
Explanation
This allows the customer to protect their file storage resources through asynchronous replication to other Dell Unity XT systems in different locations, providing a high level of data protection and disaster recovery capabilities. The asynchronous replication feature allows the customer to replicate data between systems in a way that does not affect performance, and it allows them to recover quickly from a disaster or outage.

 

NEW QUESTION 49
In vCenter, what is the correct order of steps to create a VM in a storage container provisioned on a Dell EMC PowerStore system?

Answer:

Explanation:

Explanation
STEP1:VASA
STEP2 :POWERSTORE CONNECTIVITY
STEP3:Create vvol datastore
STEP4:create vm storage policies
STEP5:Provision VMs based on vvol datastore

 

NEW QUESTION 50

What information is needed to create the NAS server?

• A. Subnet
• B. WWPN
• C. DNS details
• D. FQDN

Answer: A

 

NEW QUESTION 51
What is the purpose of the NVMe NVRAM drives in a Dell EMC PowerStore 1000 array?

• A. Write cache and base OS
• B. Write cache and vaulting
• C. Read cache and base OS
• D. Read cache and vaulting

Answer: B

Explanation:
Explanation
The base enclosure is an all-NVMe platform, capable of supporting NVMe SSD, NVMe SCM, and NVMe NVRAM drives. You can populate slots 0 through 20 with NVMe SSD or NVMe SCM drives. Slots 21 through 24 are reserved for NVMe NVRAM drives which serve as additional system write caching.
PowerStore 1000 and PowerStore 3000 models contain two NVMe NVRAM drives in slots 23 and 24.
