EMC D-PDD-DY-23 Online Practice Questions and Exam Preparation

EMC D-PDD-DY-23 Online Questions & Answers

• Question 61:

  The finance department requires PDFs that are no longer being accessed be sent to AWS S3. Which data movement policy is used?

  A. Recall
  B. Age-based
  C. Agg-driven
  D. Age-range
  B. Age-based

  ---

  Explanation

  An age-based data movement policy automatically moves data to a lower-cost storage tier (in this case, AWS S3) based on the age of the files. This means that PDFs that have not been accessed for a certain period will be identified and moved to AWS S3, aligning with the finance department's requirement to archive infrequently accessed data. This policy helps in managing storage efficiently and reducing costs by offloading older data to cheaper storage options.

• Question 62:

  Which methods are Dell Technologies recommended best practices when configuring the PowerProtect DD VTL feature and Storage Area Network?

  A. Port Zoning and worldwide name
  B. Persistent naming and Switch encryption
  C. Switch encryption and persistent Volume Claim
  D. Persistent binding and port zoning
  D. Persistent binding and port zoning

  ---

  Explanation

  Persistent binding: Ensures that devices are consistently mapped to the same target IDs or LUNs, even after reboots or SAN changes. This is important for maintaining stability and avoiding configuration issues in a SAN environment. Port zoning: Limits the devices that can communicate with each other on the SAN by controlling access based on physical ports or World Wide Names (WWNs). This enhances security and reduces the potential for disruptions in the SAN by minimizing access to the VTL.

• Question 63:

  An administrator must display the compression statistics for all files and directories in the file system for the last 7 days and the last 24 hours. Which command is used to gather this information?

  A. storage show
  B. mtree show
  C. filesys report
  D. quota show
  C. filesys report

  ---

  Explanation

  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.

• Question 64:

  SIMULATION

  Use the simulator to configure a new MTree with a path of /data/col1/oracle. The

  MTree size must not be allowed to exceed 200 TiB.

  When you have finished, continue to the next question.

  A. Check the answer in the Explanations.
  B. PlaceHolder
  C. PlaceHolder
  D. PlaceHolder
  A. Check the answer in the Explanations.

  ---

  Explanation

  To configure a new MTree with a specified path and size limit in PowerProtect DD, follow these steps:

  Step 1: Access the MTree Management Section

  In the DD System Manager interface, locate Data Management in the sidebar. Select MTree from the dropdown menu to manage MTrees.

  Step 2: Create a New MTree

  Click on Create MTree or Add MTree (the exact button label may vary).

  Set the Path for the MTree as /data/col1/oracle.

  Step 3: Set the MTree Size Limit

  In the MTree creation dialog, look for an option to set a Quota or Size Limit for the MTree.

  Set the Size Limit to 200 TiB to ensure the MTree does not exceed this capacity.

  Step 4: Save the Configuration

  Confirm and save your settings to create the MTree with the specified path and size restriction.

  After these steps, you should have a new MTree at /data/col1/oracle with a maximum allowed size of 200 TiB. Let me know if further assistance is required!

  

• Question 65:

  A backup administrator is tasked with verifying the compression savings of a PowerProtect DD3300. Which compression algorithm will they see enabled by default?

  A. gz
  B. lzw
  C. gzfast
  D. lz
  C. gzfast

  ---

  Explanation

  The gzfast compression algorithm is the default for PowerProtect DD3300, balancing compression efficiency and performance. It ensures data is compressed without compromising backup or restore speeds.

• Question 66:

  An administrator has a PowerProtect DD appliance with 32 CPU Cores and 128 GB RAM and 3 GB NVRAM. What is the maximum number of drives that they can configure with one VTL?

  A. 270
  B. 540
  C. 123
  D. 64
  B. 540

  ---

  Explanation

  PowerProtect DD appliances have specific scalability limits based on their hardware configuration. In this case, with the mentioned resources, the appliance can support a maximum of 540 drives in a single VTL configuration. This allows for extensive virtual tape storage capabilities, enhancing backup and recovery efficiency.

• Question 67:

  Which backup application uses BoostFS?

  A. IBM Spectrum Protect
  B. Quest vRanger
  C. Veritas NetBackup
  D. Dell Avamar
  D. Dell Avamar

  ---

  Explanation

  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.

• Question 68:

  Which command is used to verify the state of the disks in an expansion shelf attached to a PowerProtect DD system?

  A. disk show stats
  B. disk show state
  C. disk rescan
  D. disk status
  B. disk show state

  ---

  Explanation

  The disk show state command provides the current state of each disk in an expansion shelf, allowing administrators to monitor disk health and operational status effectively, which is crucial for maintaining data integrity.

• Question 69:

  An IBM Spectrum Protect administrator would like to use the benefits of DD Boost. Which technology will allow this integration?

  A. ICIFS
  B. NFS
  C. BooslFS
  D. VTL
  C. BooslFS

  ---

  Explanation

  BoostFS (Boost File System) is a DD Boost-enabled file system interface that allows applications like IBM Spectrum Protect to take advantage of DD Boost features, such as optimized deduplication, load balancing, and improved backup/ restore performance. By using BoostFS, IBM Spectrum Protect can efficiently integrate with PowerProtect DD appliances to leverage DD Boost's capabilities for faster and more efficient data transfer.
