Dell EMC Dell PowerProtect DD Deploy 2023 D-PDD-DY-23 Exam Practice Test

Answer : B

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.

Answer : A

The system show performance command provides an overview of the overall system performance statistics on the PowerProtect DD appliance. This includes key performance metrics such as throughput, IOPS, and other indicators that help in monitoring and diagnosing the system's operational performance.

Answer : D

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

Answer : D

BoostFS (Boost File System) is a specialized Dell EMC technology that integrates with backup applications to enable optimized data transfers to Dell EMC Data Domain systems. BoostFS works effectively with Dell's Avamar backup software, leveraging the Data Domain Boost technology to provide deduplication and improve backup efficiency. The BoostFS integration enables Avamar to utilize features like client-side deduplication, reducing data that needs to be transferred and stored on Data Domain systems, and enhancing performance and storage efficiency.

By using BoostFS with Dell Avamar, users benefit from enhanced backup speeds, optimized network bandwidth, and reduced load on the Data Domain system. The BoostFS integration also supports streamlined management and more effective use of storage resources, which aligns well with Dell EMC's strategy for comprehensive data protection.

Answer : A

The storage migration finalize command is used at the end of the storage migration process. This command removes any temporary configurations related to resources, enclosures, and migration destinations that were created during the migration process. It also restarts the file system, ensuring that the new configuration is fully implemented. Essentially, this command marks the official completion of the migration process, cleaning up any residual configurations and making the new storage setup fully operational.

Answer : C

The filesys report command provides detailed compression statistics, essential for administrators to monitor storage efficiency over time. This insight into compression ratios aids in storage optimization and management planning on PowerProtect DD systems.

Answer : B

PowerProtect DD appliances have specific limits on the number of libraries, slots, drives, and CAPs that can be configured. In this case, reaching the limit of 68 libraries likely exceeds the maximum allowed, preventing the configuration from being completed. Each component has its own limits, but in this scenario, the number of libraries is the bottleneck that prevents successful configuration.
