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

• Question 51:

  DRAG DROP

  What is the correct sequence to configure and enable Cloud Tier on a PowerProtect DD system?

  Select and Place:

  

  

  Explanation

  Disable Filesystem: This step ensures that any current filesystem operations are halted to safely modify the configuration.

  Add Available Storage: This involves allocating additional storage resources for the Cloud Tier functionality.

  Enable Filesystem: After adding storage, the filesystem needs to be re-enabled to make the system operational again.

  Configure Cloud Tier: Set up the necessary parameters and options for the Cloud Tier, specifying how it will interact with the cloud storage.

  Enable Cloud Tier: Finally, this step activates the Cloud Tier, allowing data to be tiered to cloud storage according to the configured settings.

• Question 52:

  Which are two attributes of PowerProtect DD High Availability? (Select 2)

  A. PowerProtect DD nodes are configured in active/active mode.
  B. A single set of shared storage is used.
  C. PowerProtect DD nodes should have dual heads.
  D. It is supported only on DD9900 systems.
  B. A single set of shared storage is used.
  D. It is supported only on DD9900 systems.

  ---

  Explanation

  PowerProtect DD High Availability configurations are supported on the DD9900 model with a single set of shared storage, ensuring redundancy and failover capabilities, critical for enterprise-level data protection environments. PowerProtect

  DD High Availability (HA) configuration provides a continuous availability solution, particularly suited for DD9900 systems. Here are the two key attributes of DD HA:

  Single Set of Shared Storage: In the HA configuration, both nodes in the active/standby configuration share the same set of storage. This shared storage ensures that if the active node fails, the standby node can take over without data loss,

  accessing the same storage seamlessly.

  Supported Only on DD9900 Systems: The HA feature is exclusive to high-end PowerProtect DD models, specifically the DD9900. This limitation is due to the hardware requirements needed to support the robust failover and data redundancy

  capabilities inherent in an HA setup.

• Question 53:

  What is a use case of BoostFS?

  A. To increase DD Boost throughput
  B. To enable snapshot on DD Boost data
  C. To protect applications that do not support DD Boost
  D. To implement DD Boost over Fibre Channel
  C. To protect applications that do not support DD Boost

  ---

  Explanation

  BoostFS allows applications without native DD Boost support to leverage DD Boost's deduplication benefits. It provides a seamless data protection layer across various backup applications by streamlining storage and data transfer processes. BoostFS, or Boost File System, is used to enable backup functionality for applications that do not natively support DD Boost. It allows these applications to leverage Data Domain storage efficiency by providing a file system interface. BoostFS essentially provides a method for applications without DD Boost integration to still utilize deduplication and other Data Domain benefits, making it highly effective for environments that want to standardize their storage approach but have a mix of applications with and without DD Boost support.

• Question 54:

  Which Linux distributions support BoostFS?

  A. Raspbian, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server
  B. Debian, SUSE Linux Enterprise Server, and CentOS
  C. Red Hat Enterprise Linux, CentOS, and SUSE Linux Enterprise Server
  D. CentOS, Red Hat Enterprise Linux, and Debian
  C. Red Hat Enterprise Linux, CentOS, and SUSE Linux Enterprise Server

  ---

  Explanation

  BoostFS is compatible with several Linux distributions, and the listed options include:

  Red Hat Enterprise Linux (RHEL): A widely used enterprise Linux distribution known for its stability and support.

  CentOS: A community-supported distribution derived from RHEL, providing similar functionality and compatibility.

  SUSE Linux Enterprise Server: Another enterprise-level distribution that is known for its performance and support for various applications.

• Question 55:

  Which systems support the FS25 enclosure?

  A. DD9800, DD9900, and DD6900 (HA Only)
  B. DD6900 (HA Only), DD9400 (HA Only), and DD9900 (HA Only)
  C. DD3300, DD6800, and DD9900
  D. DD9900, DD6900, and DD9400
  D. DD9900, DD6900, and DD9400

  ---

  Explanation

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

• Question 56:

  Which expansion rack supports 8 TB disk drives in the PowerProtect DD appliance?

  A. ES40
  B. FS25
  C. ES30
  C. ES30

  ---

  Explanation

  The ES30 expansion shelf is designed to support larger disk drives, including 8 TB drives, enabling the PowerProtect DD appliance to scale up its storage capacity effectively. The ES40 and FS25 racks do not support 8 TB drives, making ES30 the correct choice for this requirement.

• Question 57:

  What is enabled by the following command? authorization policy set security-officer enabled

  A. Automatic Retention Lock
  B. MTree Retention Lock Revert
  C. Dual authorization process
  D. Security encryption
  C. Dual authorization process

  ---

  Explanation

  Enabling the security-officer authorization policy activates the dual authorization process, adding a layer of security by requiring approvals for certain actions. This feature is critical for environments with strict compliance and data governance requirements.

• Question 58:

  Which feature helps to ensure that data immutability is maintained on a PowerProtect DD system?

  A. DD Retention Lock
  B. Encryption
  C. Secure Multi-Tenancy
  D. DD Replicator
  A. DD Retention Lock

  ---

  Explanation

  DD Retention Lock enforces data immutability, ensuring that critical data cannot be altered or deleted until its retention period expires. This feature is essential for regulatory compliance and data integrity in long-term storage.

• Question 59:

  Which is the default IP address assigned to PowerProtect DD iDRAC?

  A. 192.168.100.100
  B. 192.168.10.100
  C. 192.168.0.120
  D. 192.160.1.120
  C. 192.168.0.120

  ---

  Explanation

  The iDRAC (Integrated Dell Remote Access Controller) for PowerProtect DD appliances is typically set to this default IP address, allowing administrators to access the management interface for remote management and monitoring. This IP address can be changed as needed to fit the network configuration.

• Question 60:

  Which condition exists for a backup infrastructure based on PowerProtect DD?

  A. Compressed files must be decompressed before being sent to PowerProtect DD.
  B. Backup clients can write data directly to the PowerProtect DD appliance.
  C. VTL can be used to move physical tapes to a DR location.
  B. Backup clients can write data directly to the PowerProtect DD appliance.

  ---

  Explanation

  PowerProtect DD appliances allow direct data writing from backup clients, which improves efficiency and data transfer rates, leveraging DD Boost and other protocols for optimized backup performance without intermediate processing. In a PowerProtect DD backup infrastructure, backup clients are designed to write data directly to the appliance. This direct write capability is supported by protocols like DD Boost, which enhances the backup performance by offloading deduplication to the client side, reducing network bandwidth usage and speeding up backups. PowerProtect DD systems are optimized to handle direct data ingestion from backup clients, streamlining the data protection process without requiring intermediate storage or decompression steps. This feature simplifies the backup architecture and improves data protection efficiency.
