NO.61 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?

Recreate integration on the SC Series array and use only SC-to-SC replication for those volumes.

Leverage the integration investment and use only PS-to-PS replication on those volumes.

Cross-platform replication works with SC Series HIT integrations.

Cross-platform replication works with PS Series HIT integrations.

NO.62 What is the minimum number of drives in a RAID 6 dynamic pool?

* RAID 6 Dynamic Pool Configuration:
* RAID 6 provides high data protection by using double parity, allowing for two drive failures without data loss.
* Minimum Number of Drives:
* A RAID 6 dynamic pool in Dell Unity XT systems requires a minimum of 8 drives to configure.
This includes 2 drives for parity and 6 drives for data storage.
* Drive Configuration:
* The minimum configuration ensures that the system can provide the necessary data protection and redundancy while maintaining performance.
* Dell Midrange Storage References:
* Dell Unity XT documentation provides detailed guidelines on RAID configurations and the minimum requirements for various RAID levels.
* Community forums and support resources from Dell Technologies offer additional insights into RAID setup and best practices.

NO.63 A customer has three Dell PowerStore 1000Ts in a cluster and wants to add a PowerStore 5000X. What must they do?

Create a cluster with the 5000X.

Use the PowerStore CLI to add the appliance.

Reconfigure the existing cluster.

Use the PowerStore Manager to add the appliance.

* PowerStore Clustering:
* PowerStore appliances can be clustered to form a single management entity. However, adding different models within the same cluster follows specific guidelines.
* Cluster Compatibility:
* PowerStore 1000T and 5000X are different models with potentially different hardware configurations and capabilities.
* Dell recommends creating a new cluster with the PowerStore 5000X instead of mixing models within an existing cluster to ensure compatibility and optimal performance.
* Adding Appliances:
* Using the PowerStore CLI or PowerStore Manager to add appliances within the same model range is common, but mixing models generally requires creating a separate cluster.
* Dell Midrange Storage References:
* Dell PowerStore documentation provides guidelines on clustering and appliance management, highlighting the importance of model compatibility.

NO.66 Which optional I/O Module card type is supported for both Dell PowerStore T and Dell PowerStore X?

25GbE

8 Gb Fibre Channel

10GbEBaseT

32 Gb Fibre Channel

Both Dell PowerStore T and Dell PowerStore X support the 10 GbE BaseT optional I/O module card type. This card provides 10 Gbps Ethernet connectivity and can be used to connect the storage array to a network. The other options are not supported by both models. 25 GbE and 32 Gb Fibre Channel are generally faster and used for high-performance systems, while 8 Gb Fibre Channel is an older standard, and not supported by Dell PowerStore T and Dell PowerStore X.

Haswell

Ice Lake

Broadwell

Skylake

The Dell Unity XT 480 storage system uses the Broadwell CPU family. Broadwell processors are known for their efficiency and performance, making them suitable for storage systems like the Unity XT 480 that require reliable processing power for managing storage tasks.

NO.69 A customer has a Dell EMC SC9000 array with six SC420 enclosures running SCOS 7.3.
The enclosure configuration is as follows:
Two enclosures have write-intensive SSDs
Four enclosures have read-intensive SSDs
What is recommended as a general guideline for making spare drive assignments?

2 spare drives per shell

Dedicated spares are not required

2 spares per drive type per array

1 spare per drive type per shell

“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.”

NO.70 Which parameters can be selected when sizing a Dell Unity XT 480F using the System Design method?

One of four workload types
Drive count and RAID level

Data reduction ratio
Percentage of sequential writes and reads

Drive count and RAID level
Custom I/O details about workload

One of two block sizes
Application type

NO.71 A customer is using an older host OS that uses a 63-block disk header. What is the recommended host offset when connected to Dell Unity XT systems?

1 MB

16 MB

63 MB

64 MB

A customer has two Dell Unity arrays, a Dell Unity 550F, and a Dell Unity XT 480. They are undergoing a network refresh and would like to modernize to a 25 GbE network. The customer has asked the technical architect about adding 25 GbE network cards to the Unity systems. Both systems have free slots.

NO.72 What information must a solution architect gather before they start designing a storage solution?

LAN, SAN ,and Customer workload requirements

Network Infrastructure, storage, and Customer workload performance requirements

LAN, SAN, and IOPS requirements

Application response, LANand WAN requirements

NO.73 What is a benefit of cross-platform replication between Dell EMC SC Series and Dell PS Series arrays?

Leverages existing interfaces

Enables replication of volume collections

Supports cascade mode for the PS Group

Provides active snapshot replication

NO.74 Which describes cascade replication on the Dell Unity XT platform?

Synchronous replication of a block resource from Sites A to B, then B to C, then C to D

Synchronous replication of a file resource from Sites A to B, then B to C, then C to D

Asynchronous replication of a file resource from Sites A to B, then B to C, then C to D

Asynchronous replication of a block resource from Sites A to B, then B to C, then C to D

Cascade replication on the Dell Unity XT platform describes the process where a block resource is replicated asynchronously from one site to another in a sequential manner. Here’s how it works:
* Site A to Site B:The block resource is first replicated asynchronously from Site A to Site B.
* Site B to Site C:After the replication from A to B is complete, the resource is then replicated from Site B to Site C.
* Site C to Site D:Finally, the resource is replicated from Site C to Site D.
This cascade replication method allows for efficient data protection and disaster recovery across multiple sites.
