EMC DES-1D12 Online Questions & Answers

• Question 81:

  A customer must protect file storage resources through asynchronous replication to other Dell Unity XT systems in different locations. What is the maximum number of remote systems that can be configured?

  A. 4
  B. 24
  C. 16
  D. 8
  B. 24

  ---

  Explanation/Reference:

  This allows the customer to protect their file storage resources through asynchronous replication to other Dell Unity XT systems in different locations, providing a high level of data protection and disaster recovery capabilities. The asynchronous replication feature allows the customer to replicate data between systems in a way that does not affect performance, and it allows them to recover quickly from a disaster or outage.

• Question 82:

  A. NAS Network Heartbeat
  B. RAID protected disk drives
  C. Multiple redundant network ports with system bond
  D. Redundant nodes with Live Volume enabled
  C. Multiple redundant network ports with system bond

• Question 83:

  For Dell EMC SC Series arrays, what is the minimum percentage of total system IOPS that should be applied to Tier 3 drives?

  A. 15%
  B. 20%
  C. 25%
  D. 100%
  B. 20%

  ---

  Explanation/Reference:

  "As a standard, tier 3 drives should encompass a minimum of 20% system IOPS potential."

• Question 84:

  Which path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type?

  A. Application Oriented
  B. Data Input
  C. Quick Configuration
  D. System Designer
  D. System Designer

  ---

  Explanation/Reference:

  The System Designer path of the size tool for Dell Unity XT uses predefined configurations that are based on array model capacity points, random workloads RAID type and drive type. This path is designed to make the sizing process quick and easy, providing recommended configurations that are optimized for specific array models and workloads. It allows the user to select an array model, and then it will provide a set of predefined configurations that meet the desired capacity, performance, and availability requirements.

• Question 85:

  When enabling a multi-protocol NAS implementation on a Dell EMC PowerStore array, what is required for an end-to-end mapping of a UNIX system?

  A. Security ID (SID) and Active Directory (AD)
  B. User ID (UID) and Group ID (GID)
  C. Group ID (GID) and Active Directory (AD)
  D. Security ID (SID) and User ID (UID)
  B. User ID (UID) and Group ID (GID)

  ---

  Explanation/Reference:

  In multiprotocol implementations (both SMB and NFS protocols enabled), an end Windows Security ID (SID) to UNIX User ID (UID) and Group ID (GID) is required.

• Question 86:

  You are designing a Dell EMC PowerStore solution with a customer. They ask if they can populate Slots 0 to 10 with NVMe SSD drives.

  What should be your response?

  A. Any drive type can be populated in the remaining slots
  B. NVMe SSDs must be populated in the remaining empty slots
  C. NVMe SCM drives are required in Slots 0 through 10
  D. NVMe SCM drives must be populated in the remaining empty slots
  B. NVMe SSDs must be populated in the remaining empty slots

• Question 87:

  A customer configures their Live Volume setup for synchronous replication with the High Availability option. They are designing a DR resiliency plan to ensure data integrity in the event of data corruption. Which Dell EMC SC Series technology should you use?

  A. Live Volume with Non-Uniform Presentation
  B. Live Volume with Uniform Presentation
  C. Synchronous Replication with High Consistency
  D. Live Volume with Managed Replication
  D. Live Volume with Managed Replication

• Question 88:

  A Dell PowerStore 9000X came online after being initially configured seven days ago. The manager Ul shows capacity but no forecasting metrics

  Why are forecasting metrics not being displayed?

  A. Forecasting was not turned on during configuration
  B. The capacity forecasting license must be installed
  C. There is not enough capacity in the appliance
  D. Forecasting will not display until 16 days after initial configuration
  B. The capacity forecasting license must be installed

  ---

  Explanation/Reference:

  Capacity forecasting requires the installation of a special license to display capacity forecasting metrics. If the license is not installed, then the forecasting metrics will not be displayed.

• Question 89:

  An administrator wants to use NAS Server Mobility to move a NAS server from SPA to SPB on a Dell Unity system What consideration must they be aware of?

  A. DNS configuration will be lost after the move
  B. NAS Server Mobility is no longer supported following a software update
  C. Any replication sessions must be in a paused state before starting the move
  D. The system must be in service mode to complete the move
  C. Any replication sessions must be in a paused state before starting the move

  ---

  Explanation/Reference:

  When using NAS Server Mobility to move a NAS server from SPA to SPB on a Dell Unity system, an administrator must be aware that any replication sessions must be in a paused state before starting the move. This means that any data replication sessions that are configured for the NAS server must be temporarily stopped to avoid data inconsistencies or data loss during the move. Once the move is complete, the replication sessions can be resumed, and data replication will continue as normal. NAS Server Mobility is still supported by Dell Unity, so it's not a concern of the move. The system does not need to be in service mode to complete the move, and the DNS configuration won't be lost after the move, the administrator should make sure that the DNS entries for the NAS server are updated to reflect the new location.

• Question 90:

  Which features were introduced in SCOS 7.3?

  A. Distributed Sparing and Live Volume ALUA
  B. Data-in-Place upgrade for SC4020 and 4K HDD support
  C. Unisphere for SC and Live Volume Auto-failover
  D. CloudlQ support and Cross Platform Replication
  A. Distributed Sparing and Live Volume ALUA
