A. Synchronous replication of a file resource from Sites A to B. then B to C then C to D B. Asynchronous replication of a block resource from Sites A to B then B to C then C to D C. Synchronous replication of a block resource from Sites A to B. then B to C. then C to D D. Asynchronous replication of a file resource from Sites A to B then B to C. then C to D Answer: D Explanation: Cascade replication refers to the replication of data from one site to another, in a sequential or cascading manner. In the case of Dell Unity XT, cascade replication refers to the asynchronous replication of a file resource from one site (site A) to another (site B), then from site B to another site (site C) and so on. This means that data is replicated from one site to another in an orderly fashion, and each site functions as 8 / 9 both a source and a target for replication. This allows for multiple copies of the data to be kept in different locations, providing increased data availability and disaster recovery capabilities. It's important to note that cascade replication can also be used for block resources but is usually asynchronous. 22.How should Dell Unity XT storage pools be configured to minimize the chance of running out of space due to snapshot utilization? A. Set high and low watermarks to remove old snapshots B. Set retention to a particular date and time C. Change the number of days in the local retention policy D. Change the frequency period on the snapshot schedule Answer: A Explanation: Dell Unity XT storage pools can be configured to minimize the chance of running out of space due to snapshot utilization by setting high and low watermarks to remove old snapshots. A high watermark is set to specify the maximum amount of space that can be consumed by snapshots before the oldest snapshots are automatically removed. This is a good way to ensure that snapshots do not consume all available space, and helps to prevent the pool from running out of space. 23.DRAG DROP Match each Dell EMC Unity feature with its destination.

Cross-platform replication works with SC Series HIT integrations. D. Cross-platform replication works with PS Series HIT integrations. Answer: C 25.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 two NAS servers place all Linux data in one and all Windows data in the other B. Configure a snapshot rule and protection policy and apply it to the file system C. Configure multiprotocol access to required file system D. Configure file data to be replicated for access by different client types Answer: C 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 26.Which are benefits of choosing the highest capacity flash drives when designing a Dell Unity XT All-Flash system?
