EMC EMC Certifications DES-1D12 Questions & Answers

• Question 31:

  How many expansion enclosures can be added to a Dell PowerStore 1000T that has 10 SCM drives in the base enclosure?

  A. 0

  B. 1

  C. 3

  D. 2

  Correct Answer: B

  Dell PowerStore 1000T supports the addition of a maximum of one expansion enclosure when it has 10 SCM drives in the base enclosure. An expansion enclosure can be added to the base enclosure and allows the system to support additional drives and increase storage capacity.

• Question 32:

  Which methods are available to migrate storage resources from one Dell PowerStore appliance to another within the same cluster?

  A. Assisted Migration and Live Migrate

  B. Migrate and Assisted Migration

  C. Assisted Migration and Volume Motion

  D. Volume Motion and Live Migrate

  Correct Answer: C

  The Dell PowerStore appliance provides two methods to migrate storage resources within the same cluster: Assisted Migration and Volume Motion. Assisted Migration: This method allows the administrator to manually initiate and control the

  migration process, and it allows for the migration of individual resources such as LUNs, file systems and snapshots.

  Volume Motion: This method allows the administrator to move a LUN or file system from one storage pool to another on the same PowerStore appliance or within the same cluster. This is done without any disruption to the hosts accessing the

  data and it can be automated with the use of policies.

  It's important to note that the Live Migrate and Migrate options are not available to migrate storage resources within the same cluster in Dell PowerStore.

• Question 33:

  A customer has implemented five new Dell PowerStore 1000T model arrays for remote office sites. The arrays are going to need more capacity than originally thought What NVRAM considerations must be evaluated before adding the new capacity?

  A. Use the DSA ordering system to determine if more NVRAM is supported for the PowerStore model

  B. Another NVRAM is only needed if adding an expansion shelf

  C. The 1000T only supports two NVRAM modules

  D. Use the Dell PowerStore Manager Ul to determine if more NVRAM is needed

  Correct Answer: D

  It's important to check if more NVRAM is needed before adding new capacity to ensure that the system has enough resources to handle the increased workload. The Dell PowerStore Manager UI can provide information on the current NVRAM usage and capacity, and can also be used to order additional NVRAM if needed.

• Question 34:

  What is a best practice for host connectivity on Dell EMC PowerStore?

  A. HBAs must be attached to a dual fabric and multi-path software is required

  B. Requires multipath software and one HBA

  C. Host must be directly attached, but there is no requirement for multipath software

  D. Requires multipath software and iSCSI

  Correct Answer: D

• Question 35:

• Question 36:

  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

  Correct Answer: D

• Question 37:

  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

  Correct Answer: C

  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 38:

  What is the maximum number of data drives that can be put in to a Dell PowerStore 1000T base enclosure?

  A. 23

  B. 21

  C. 25

  D. 24

  Correct Answer: B

  The maximum number of data drives that can be put in to a Dell PowerStore 1000T base enclosure is 21. The Dell PowerStore 1000T has a 2U form factor, and it supports a maximum of 21 drives in the base enclosure. The drives can be either SAS or NVMe, and it's important to keep in mind that the maximum capacity of the system depends on the type of drives that are used. It's important to note that the PowerStore 1000T supports up to 2 expansion shelves that can hold an additional 21 drives each, for a maximum of 63 drives in total. Also, the PowerStore 1000T supports up to 4 NVRAM modules that are used to cache metadata and improve performance.

• Question 39:

  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

  Correct Answer: A

  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 40:

  Which NVMe SSDs are supported by Dell EMC PowerStore?

  A. 960 GB, 1920 GB, 3840 GB, and 7680 GB

  B. 3840 GB, 7680 GB, and 15360 GB only

  C. 1920 GB, 3840 GB, and 7680 GB only

  D. 1920 GB, 3840 GB, 7680 GB, and 15360 GB

  Correct Answer: D
