EMC DES-1D12 Online Questions & Answers

• Question 1:

  A customer wants to asynchronously replicate file data from a production Dell Unity 550F to a remote office in the same city with a UnityVSA When attempting to replicate one of the file systems the replication option is not available.

  What should a technical architect advise the customer?

  A. Asynchronous replication is not supported to a UnityVSA
  B. The NAS server for the file system must be replicated
  C. Asynchronous replication requires a greater replication distance
  D. Only synchronous replication is supported on file systems
  C. Asynchronous replication requires a greater replication distance

  ---

  Explanation/Reference:

  Asynchronous replication can be used to replicate data over larger distances than synchronous replication. However, it cannot be used to replicate data between two UnityVSA systems within the same city. To replicate file data from a production Dell Unity 550F to a remote office in the same city with a UnityVSA, the technical architect should advise the customer to use synchronous replication.

• Question 2:

  When designing a Dell EMC Unity 480F solution, what is the maximum number of enclosures and drive slots, per bus?

  A. 10 enclosures and 250 drive slots
  B. 10 enclosures and 750 drive slots
  C. 3 enclosures and 240 drive slots
  D. 10 enclosures and 500 drive slots
  A. 10 enclosures and 250 drive slots

  ---

  Explanation/Reference:

  NOTE General DAE back-end bus configuration rules:

  Maximum number of enclosures per bus is 10.

  Maximum number of drive slots per bus is 250, up to specific system limitations for drive slots.

• Question 3:

  A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity feature could reduce failover times?

  A. QoS Failover Policy
  B. Cabinet Failover
  C. SRDF Metro
  D. Consistency Groups
  B. Cabinet Failover

• Question 4:

  A customer has a Dell EMC Unity 680F array with a single pool consisting of 10 drives configured with RAID 5 (4+1). What is the minimum number of drives required to expand the pool?

  A. 1
  B. 5
  C. 6
  D. 7
  B. 5

  A. NVMe disks
  B. SEDs
  C. 1 GbE I/O modules
  D. 25 GbE I/O modules
  A. NVMe disks

• Question 7:

  How many hierarchical snapshots are supported by Dell EMC PowerStore 9000X array?

  A. 0 levels deep for LUNs 0 levels deep for file systems
  B. 32 levels deep for LUNs 16 levels deep for file systems
  C. 10 levels deep for LUNs 10 levels deep for file systems
  D. 16 levels deep for LUNs 16 levels deep for file systems
  C. 10 levels deep for LUNs 10 levels deep for file systems

• Question 8:

  A customer with a Dell Unity 550F has recently upgraded to the Unity OE 5 0 release They want to use the Advanced Deduplication feature to reduce the used data capacity in a dynamic storage pool LUNs in the pool have the feature enabled but the pool used capacity has not reduced

  What is one way to fix this problem?

  A. Sequentially reboot both Storage Processors
  B. Free up at least 50% capacity to the pool
  C. Trespass the LUNs to the peer Storage Processor
  D. Move the LUNs to a different pool
  D. Move the LUNs to a different pool

• Question 9:

  A user is storing data on the quota tree on a Dell PowerStore system.

  What can an administrator use to limit the amount of storage that the user consumes?

  A. User quota on the tree quota
  B. A NAS server quota
  C. A bandwidth throttle quota
  D. A second tree quota
  A. User quota on the tree quota

  ---

  Explanation/Reference:

  An administrator can use a user quota to limit the amount of storage that the user consumes on a Dell PowerStore system. A user quota is a limit that is set on the quota tree, which is a hierarchical structure that organizes storage resources and sets limits on how much storage can be used at each level. The user quota is applied to a specific user or group of users and limits the amount of storage that can be consumed by that user or group of users.

• Question 10:

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

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