DELL D-PDD-DY-23 Practice Test - Questions Answers

The FS25 enclosure is compatible with DD9900, DD6900, and DD9400, providing additional storage capacity and performance capabilities tailored for high-demand PowerProtect DD deployments.

The FS25 expansion shelf must be cabled on a separate private chain to avoid performance degradation and potential conflicts with other shelf types. This cabling rule ensures optimal data flow and stability within the PowerProtect DD system.

The best practice for fabric zoning with PowerProtect DD Virtual Tape Library (VTL) is single initiator-single target zoning. This configuration minimizes cross-talk and reduces risks of interference, resulting in a more stable and secure data transfer environment.

Copy the active tier data from the existing system to the new system.

Disconnect the cloud storage from the existing system.

Connect the cloud storage to the new system.

Copy the cloud tier metadata from the existing system to the new system.

Commit the migration operation.

When a DS60 shelf is already part of the configuration, a maximum of 5 ES40 SAS shelves can be added to maintain balance and prevent overloading the system's data handling capabilities. This limit ensures optimal performance and reliability.

By enabling Smart Scale services from DDMC, the Smart Scale architecture pools together a set of DD series appliances into a group under the data center in which they are coordinated with each other for space balancing. Smart Scale supports up to 32 systems in a system pool and four system pools in a data center.

When implementing Link Aggregation Control Protocol (LACP) on a PowerProtect DD appliance, a virtual network interface is created to aggregate the physical interfaces into a single logical link. This configuration is essential to enable LACP functionality, as it allows the system to balance network traffic effectively across multiple physical connections, enhancing redundancy and throughput. By aggregating these physical interfaces, the appliance can better handle high data volumes, providing stable and efficient access to the underlying network resources.

The virtual network interface manages the logical grouping, ensuring seamless failover and load balancing between the physical links that comprise the aggregated connection.

PowerProtect DD allows up to 750 snapshots per MTree, supporting efficient data protection and recovery with minimal impact on storage resources. This feature provides extensive backup versioning options for granular data recovery.

When a source system is in restricted mode, certain maintenance tasks, like file system cleaning, are unavailable. This restriction is typically applied during migrations to prevent data inconsistencies, ensuring a smooth transfer of data to the new system.

During the migration process from an older Data Domain system with cloud tier capabilities to a new PowerProtect DD appliance, the source system operates in a 'restricted mode.' This restricted mode limits specific functionalities, including file system cleaning. File system cleaning is a maintenance operation that reclaims storage by deduplication and cleaning up obsolete data. However, to prevent data inconsistency or interference during migration, this functionality is temporarily disabled on the source system, thus ensuring data integrity until the migration process is completed.

The restricted mode ensures that all critical operations remain stable and predictable on the source system, which is essential for a smooth migration to the new environment.
