NEW QUESTION # 26
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 snapshot of the database volume and map it to the test host
- B. Create a thin clone of the database volume and map it to the test host
- C. Restore the snapshot to a new test volume
- D. Create a new snapshot policy for the test volume
Answer: B
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.
NEW QUESTION # 27

NEW QUESTION # 28
A Dell PowerStore administrator has been asked to create a NAS file sharing environment for several clients.
The clients will be running either Linux (NFS) or Windows (SMB) and must have access to the same data simultaneously How can this be achieved using Dell PowerStore?
- A. Configure a snapshot rule and protection policy and apply it to the file system
- B. Configure two NAS servers place all Linux data in one and all Windows data in the other
- C. Configure file data to be replicated for access by different client types
- D. Configure multiprotocol access to required file system
Answer: D
Explanation:
Explanation
Dell PowerStore allows you to create a NAS file sharing environment for several clients by configuring multiprotocol access to the required file system. This means that the same file system can be accessed by both Linux and Windows clients using either the NFS or SMB protocols. This can be achieved by creating a file system, and configuring it to allow access using both the NFS and SMB protocols. Once the file system is set up, you can assign permissions and share the file system with the appropriate clients. This way, the clients will be able to access the same data simultaneously, regardless of whether they are running Linux or Windows and which protocol they are using. It's not necessary to replicate data for access by different client types, it would be an extra step that would consume more resources and would be unnecessary
NEW QUESTION # 29
At what granularity are blocks deduplicated on a Dell EMC PowerStore array?
- A. 8 KB
- B. 4 KB
- C. 32 KB
- D. 64 KB
Answer: B
Explanation:
Explanation
https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/storage/h18151-dell-emc-powers Deduplication uses algorithms to analyze, perform pattern detection, and attempts to store only a single instance of data. In general deduplication can work at the block, bit-level, or file level. In PowerStore, deduplication works at the block level at 4 KB granularity.
NEW QUESTION # 30
A technical architect is helping a customer prepare for a data center maintenance window All applications must failover to the disaster recovery site The customer also wants to test their disaster recovery plan What PowerStore Manager replication option should be used to address the customer's need: and from which site should the option be run?
- A. Planned failover from target site
- B. Failover from source site
- C. Failover from target site
- D. Planned failover from source site
Answer: A
Explanation:
Explanation
The technical architect should use the "Planned failover" option from the target site to address the customer's need for a disaster recovery test and to prepare for a data center maintenance window. A planned failover allows the customer to test their disaster recovery plan and make sure that all applications are able to failover to the disaster recovery site without interrupting the production environment. During a planned failover, the data is written to the target site and acknowledged to the host, but the data is not yet cutover to the target site.
This allows the customer to validate the failover and cutover only when they are ready. A "Planned failover" option should be run from the target site, this way all the data that is replicated to the target site is already available and ready to be used in case of a real disaster. A "Failover" option should only be used in case of an unplanned disaster, and the data would be lost in a certain amount of time.
