8 levels deep for file systems

10 levels deep for file systems
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
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.
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
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.
Which front-end protocol card in Dell Unity XT 380 offloads processing to save CPU cycles for other operations? A . Fibre Channel
B. CNA fonSCSI
D. CNA for Fibre Channel
(Converged Network Adapter for iSCSI) is the front-end protocol card in Dell Unity XT 380 that offloads processing to save CPU cycles for other operations. It enables the Unity XT 380 to handle iSCSI traffic, which reduces the workload on the host server’s CPU and improves overall system performance.
What are characteristics of [email protected] on a Dell EMC Unity array? A . Impacts array only during implementation Has minimal impact on performance
B. Does not impact array during implementation Has some impact on performance for a moment
C. Impacts array for a moment after implementation Has no impact on performance
D. Does not impact array during implementation Has minimal impact on performance
controller-based [email protected] has minimal performance impact for typical mixed workloads, and no impact to other Dell EMC Unity data services due to the level at which the encryption is performed, which is after all data services have been applied.
Which feature helps to enable file service High Availability on Dell EMC PowerStore? A . NAS Network Heartbeat
B. RAID protected disk drives
C. Multiple redundant network ports with system bond
D. Redundant nodes with Live Volume enabled
Which describes cascade replication on a Dell Unity XT? 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
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 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.
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
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
A customer has invested much time using the Dell PS Series Host Integration Toolkit (HIT) to integrate SAN snapshot protection with Microsoft SQL Server native snapshot technology. The customer expresses concern about whether Dell EMC SC Series cross-platform replication supports that capability.
What should be your response? A . Recreate integration on the SC Series array and use only SC-to-SC replication for those volumes.
B. Leverage the integration investment and use only PS-to-PS replication on those volumes.
C. Cross-platform replication works with SC Series HIT integrations.
D. Cross-platform replication works with PS Series HIT integrations.
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
