Show answer & explanation
- Question 2
A customer has invested much time using the Dell PS Series Host Integration Toolkit (HIT) to integrate SAN snapshot protection with Microsoft SQL Server native snapshot technology. The customer expresses concern about whether Dell EMC SC Series cross-platform replication supports that capability.
What should be your response?
Show answer & explanation
Correct answer: B
B
- Question 3

PowerStore Architecture · Dynamic Resiliency Engine (DRE)
A Solution Architect is designing a new Dell PowerStore T solution for a financial institution. The customer requires strict adherence to data redundancy policies that can withstand simultaneous drive failures within the same appliance without data loss.
Which Dynamic Resiliency Engine (DRE) configuration should be recommended to meet the requirement for double drive failure tolerance while maximizing usable capacity?
Show answer & explanation
Correct answer: B
PowerStore's Dynamic Resiliency Engine (DRE) allows administrators to select redundancy levels. To tolerate two simultaneous drive failures, DRE Double Parity (conceptually similar to RAID 6) is required. Single parity only protects against one drive failure.
- Question 6Intermediate
Unity Features · Data Reduction
A storage administrator is configuring a Dell Unity XT 480F system. They need to create a new storage pool that supports Advanced Deduplication.
Which prerequisite must be met to enable this feature?
Show answer & explanation
Correct answer: C
On Dell Unity systems, Advanced Deduplication is an optional extension of the data reduction capabilities. To enable Advanced Deduplication, Data Compression must be enabled first. It is supported on All-Flash pools (Dynamic Pools).
- Question 7Beginner
PowerStore Architecture · AppsON
You are designing a PowerStore X solution for an environment that requires running applications directly on the storage array using AppsON.
Which component manages the compute resources for these internal virtual machines?
Show answer & explanation
Correct answer: B
PowerStore X models utilize an onboard ESXi hypervisor to run both the PowerStoreOS (in a controller VM) and customer applications (AppsON). This allows VMs to run directly on the storage hardware.
- Question 8Intermediate
Sizing and Design · Midrange Sizer
A customer plans to use the Dell Midrange Sizer to model a Unity XT solution. They specifically need to validate that the proposed configuration can handle a workload of 50,000 IOPS with a 70/30 Read/Write ratio and 8KB block size.
Which workflow in the Midrange Sizer tool is best suited for this specific requirement?
Show answer & explanation
Correct answer: B
The Performance-Oriented Sizing workflow (often labeled 'Performance' or 'Workload' path) allows the architect to input specific IOPS, block sizes, and read/write ratios to generate a configuration that meets those specific performance KPIs. The Quick Configuration path focuses on capacity.
- Question 9BeginnerSelect 2
PowerStore Architecture · Connectivity
Which TWO protocols are supported for the Front-End connectivity on a PowerStore T model? (Select TWO)
Show answer & explanation
Correct answers: C, D
PowerStore T supports Fibre Channel (16/32Gb) and iSCSI (10/25GbE) for block storage connectivity, along with NAS protocols.
PowerStore T supports Fibre Channel (16/32Gb) and iSCSI (10/25GbE) for block storage connectivity, along with NAS protocols.
- Question 10Advanced
Unity Features · File Level Retention
An administrator receives an alert that a File System on a Unity XT array has reached 90% capacity. They decide to enable File-Level Retention (FLR) on this existing file system to prevent accidental deletion of critical data.
What will be the outcome of this action?
Show answer & explanation
Correct answer: B
On Dell Unity systems, File-Level Retention (FLR) is a property that must be set at the time of file system creation. It cannot be enabled on an existing file system that was created without it. The administrator would need to create a new FLR-enabled file system and migrate the data.
- Question 11Beginner
PowerStore Architecture · Scale-Out
True or False: A Dell PowerStore cluster can scale out to a maximum of 4 appliances.
Show answer & explanation
Correct answer: A
PowerStore supports scale-out clustering of up to 4 appliances (nodes pairs) in a single cluster, providing linear scaling of compute and storage resources.
- Question 12Intermediate
PowerStore Features · Snapshots and Clones
During a design workshop for a PowerStore solution, the customer asks about the granularity of the thin clones. They want to know if creating a thin clone of a volume group is supported and how it behaves.
What is the correct behavior of Thin Clones in PowerStore regarding Volume Groups?
Show answer & explanation
Correct answer: B
PowerStore supports cloning Volume Groups. When you clone a VG, it creates a new VG that contains independent thin clones of all the volumes that were in the source group, maintaining write-order consistency.
- Question 13Advanced
Migration and Import · Non-Disruptive Import
A consultant is performing a non-disruptive import of data from an external storage array to a PowerStore cluster. Which host-side component is essential for the Non-Disruptive Import (NDI) process to function correctly during the cutover phase?
Show answer & explanation
Correct answer: D
For Non-Disruptive Import (NDI) to PowerStore, the host OS must have the appropriate Host Plugin (for Windows, Linux, or VMware) installed. This plugin manages the path flip and I/O redirection during the import process to ensure the application stays online.
- Question 14Beginner
Unity Features · Replication
When configuring a Dell Unity XT system for asynchronous replication, what is the default RPO (Recovery Point Objective) available in the Unisphere wizard?
Show answer & explanation
Correct answer: B
While Unity supports RPOs as low as 5 minutes, the default setting presented in the Unisphere replication wizard is typically 60 minutes. Administrators can adjust this based on requirements.
- Question 15Advanced
Sizing and Design · Replication Sizing
A storage architect is sizing a solution and needs to calculate the bandwidth required for replication. The source volume has a daily change rate of 500 GB, and the replication window is 8 hours.
What is the approximate minimum bandwidth required (ignoring protocol overhead and compression benefits)?
Show answer & explanation
Correct answer: C
Calculation: 500 GB * 1024 * 8 = 4,096,000 Mbits (Total bits). Time = 8 hours * 3600 seconds = 28,800 seconds. Bandwidth = 4,096,000 / 28,800 ≈ 142 Mbps. The closest standard requirement is ~140 Mbps.
- Question 16Beginner
Management · CloudIQ
Which CloudIQ feature provides a proactive health score for Dell storage systems, ranging from 0 to 100?
Show answer & explanation
Correct answer: C
CloudIQ aggregates alerts, performance, and capacity metrics into a single Health Score (0-100) to give administrators an immediate understanding of the system's status.
