  A. Container Integration
  B. Configured Block with Hypervisor
  C. Unified System
  D. NVMe disks
  C. Unified System

  ---

  Explanation/Reference:

  "When positioning the 380 and 380F, keep in mind that they are not NVMe-ready and will not be upgradeable to support NMVe in the future.".

• Question 92:

  How should Dell Unity XT storage pools be configured to minimize the chance of running out of space due to snapshot utilization?

  A. Set high and low watermarks to remove old snapshots
  B. Set retention to a particular date and time
  C. Change the number of days in the local retention policy
  D. Change the frequency period on the snapshot schedule
  A. Set high and low watermarks to remove old snapshots

  ---

  Explanation/Reference:

  Dell Unity XT storage pools can be configured to minimize the chance of running out of space due to snapshot utilization by setting high and low watermarks to remove old snapshots. A high watermark is set to specify the maximum amount of space that can be consumed by snapshots before the oldest snapshots are automatically removed. This is a good way to ensure that snapshots do not consume all available space, and helps to prevent the pool from running out of space.

• Question 93:

  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
  D. Requires multipath software and iSCSI

• Question 94:

  A customer has a Dell EMC SC9000 array with six SC420 enclosures running SCOS 7.3. The enclosure configuration is as follows:

  1.

  Two enclosures have write-intensive SSDs

  2.

  Four enclosures have read-intensive SSDs

  What is recommended as a general guideline for making spare drive assignments?

  A. 2 spare drives per shell
  B. Dedicated spares are not required
  C. 2 spares per drive type per array
  D. 1 spare per drive type per shell
  B. Dedicated spares are not required

  ---

  Explanation/Reference:

  "SCOS 7.3, Distributed Sparing: eliminates the need for dedicated spares by giving customers the option to distribute sparing capacity across all drives in the array."

• Question 95:

  How many replication rules can be applied to a cluster in Dell EMC PowerStore?

  A. 16
  B. 24
  C. 32
  D. 64
  C. 32

  ---

  Explanation/Reference:

  Limit per cluster = 32 replication rules

• Question 96:

  A solutions architect must present two different Dell PowerStore options to a customer Both options must contain 90 TB raw in the smallest drive configuration possible A 3000T and a 9000T are the two models requested The customer wants to know the minimum drive count necessary to perform a capacity upgrade

  Which solution should be recommended?

  A. A 6x 15 TB drives in the 3000T and 6x 15 TB drives in the 9000T both requiring upgrades in six drive increments
  B. 6x 15 TB drives in the 3000T and 12x 7 TB drives in the 9000T both supporting single drive upgrades
  C. 6x 15 TB drives in the 3000T and 6x 15 TB drives in the 9000T both supporting single drive upgrades
  D. 12x 7 TB drives in the 3000T and 6x 15 TB drives in the 9000T both requiring upgrades in six drive increments
  C. 6x 15 TB drives in the 3000T and 6x 15 TB drives in the 9000T both supporting single drive upgrades

  ---

  Explanation/Reference:

  This option provides the smallest drive configuration possible for both the 3000T and 9000T models, and allows for single drive upgrades, which is more flexible for the customer.

• Question 97:

  Which Dell EMC SC Series array allows for back-end expansion cards?

  A. SCv3000
  B. SC7020
  C. SC5020
  D. SCv3020
  B. SC7020

• Question 98:

  A Dell PowerStore protection policy contains two snapshot rules and one replication rule Which storage resources will run only the snapshot rules?

  A. Virtual Machines and File Servers
  B. Volumes and Volume Groups
  C. Virtual Machines and File Systems
  D. Volume Groups and File Systems
  B. Volumes and Volume Groups

  ---

  Explanation/Reference:

  A Dell PowerStore protection policy contains two snapshot rules and one replication rule, and it applies to specific storage resources such as volumes and volume groups. These resources will run only the snapshot rules, not the replication rule. A snapshot rule allows you to create point-in-time copies of the data, which can be used to recover data in case of data loss or corruption. Snapshot rules are applied to specific volumes or volume groups, and only these resources will be backed up with the snapshot. A replication rule allows you to replicate data to a remote site for disaster recovery or data protection. Replication rules are applied to different resources such as Virtual Machines, File Servers, File Systems, etc. In this case, the snapshot rules will be applied to Volumes and Volume Groups, and the replication rule will be applied to other resources such as Virtual Machines, File Servers, File Systems.

• Question 99:

  You are designing a Dell EMC Unity solution. You need to model expected array performance based om IOPS capability, storage capacity, and RAID type. Which Midrange Sizer design path should you take?

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