EMC DES-1D12 Dumps – Secret To Pass in First Attempt

Q15. A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity feature could reduce failover times?

QoS Failover Policy

Cabinet Failover

SRDF Metro

Consistency Groups

Q16. 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?

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

Another NVRAM is only needed if adding an expansion shelf

The 1000T only supports two NVRAM modules

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

Q17. Match each Dell EMC Unity feature with its definition.

Q18. Which block resources are supported with Dell EMC Unity asynchronous replication?

Consistency Groups and file systems

VMFS and NFS datastores

LUNs and VMFS datastores

LUNs and file systems

Q19. What component or feature is provided by both the Dell EMC Power Store1000T array and the Dell EMC Unity XT 380 Series array?

Unified System

Container Integration

Configured Block with Hypervisor

NVMe disks

Q20. How many hierarchical snapshots are supported by Dell EMC Unity?

32 levels deep for LUNs
16 levels deep for file systems

16 levels deep for LUNs
8 levels deep for file systems

16 levels deep for LUNs
16 levels deep for file systems

10 levels deep for LUNs
10 levels deep for file systems

Q21. What is a key feature of the Dell EMC Future-Proof Storage Loyalty Program for Dell EMC SC Series arrays?

4:1 Performance Guarantee

4 Year Satisfaction Guarantee

4:1 Reduction Guarantee

4:1 Efficiency Guarantee

Dell EMC Flash Storage Efficiency Guarantee Dell EMC promises our flash arrays will provide a logical usable capacity at least four times the usable physical capacity of your purchased drives -or we’ll give you more drives at no charge. https://www.delltechnologies.com/en-us/blog/dell-emc-flash-storage-efficiency/

Q22. Which Dell EMC Unity feature provides network high availability with active-passive ports when provisioning File storage for a NAS client?

Redundant Interfaces

Preferred Interfaces

Link Aggregation

Fail-safe Networking

Document: docu71319_dell-emc-unity-high-availability-a-detailed-review.pdf Page: 20 FAIL SAFE NETWORKING (FSN) Dell EMC Unity OE version 4.2.1 introduces Fail Safe Networking (FSN). FSN is a high availability feature that extends link failover into the network by providing switch-level redundancy. FSN appears as a single link with a single MAC address and potentially multiple IP addresses. FSN can consists of Ethernet ports, link aggregations, or any combination of the two. FSN adds an extra layer of availability to link aggregations alone as link aggregations provide availability in the event of a port failure while FSN provides availability in the event of a switch failure. Each port or Link aggregation is considered as a single connection and only the primary port or link aggregation in an FSN is active at a time. All ports in an FSN must have the same MTU size, but the speed and duplex settings can vary.

Q23. Which Dell PowerStore supported media devices carry a FIPS Type D certification?

NVMe SCM NVMe SSD, and SAS SSD

SAS HDD. NVMe SSD NVMe SCM, and SAS SSD

SAS SCM NVMe SSD and NVRAM

SAS SSD NVMe SSD NVMe SCM, and NVRAM

Q24. Which methods are available to migrate storage resources from one Dell PowerStore appliance to another within the same cluster?

Assisted Migration and Live Migrate

Migrate and Assisted Migration

Assisted Migration and Volume Motion

Volume Motion and Live Migrate

Q25. At what granularity are blocks de duplicated on a Dell EMC Power Store array?

4KB

8KB

32KB

64KB

Q26. A storage administrator is trying to create a new hybrid pool on their Dell Unity XT 680 They want to add
* 18×3.84 TBSSD drives
* 72x 1200 GB 10K SAS drives
* 64x 12 TBNLSAS drives
However, this action is not being permitted by the Unity software. What is the reason for this’>

3.84 TB SSD are only supported in all flash pools

There are too many disks in the SAS tier

12 TB NLSAS drives are only permitted in archive pools

The pool must be created with only a single drive type

Explanation
The storage administrator is not able to create a new hybrid pool on their Dell Unity XT 680 because the 3.84 TB SSD drives are only supported in all flash pools. Dell Unity XT supports the use of SSDs in all-flash pools, where the entire pool is built from SSD drives, to provide high performance for I/O-intensive workloads.

Q27. At what granularity are blocks deduplicated on a Dell EMC PowerStore array?

4 KB

8 KB

32 KB

64 KB

https://www.delltechnologies.com/resources/en-us/asset/white-papers/products/storage/h18151-dell-emc-powerstore-data-efficiencies.pdf Deduplication uses algorithms to analyze, perform pattern detection, and attempts to store only a single instance of data. In general deduplication can work at the block, bit-level, or file level. In PowerStore, deduplication works at the block level at 4 KB granularity.

Q28. You are upgrading a Dell EMC Unity array to a Dell EMC PowerStore 1000 T array. The customer asks what they need to do so they can map PowerStore snapshots from the new PowerStore array to a host.
What should be your response?

Create a volume group of the snapshot.

Create a read/write snapshot of the snapshot

Create a copy of the snapshot

Create a thin clone of the snapshot

Explanation
“Volume and Volume Group Snapshots: Snapshots cannot be mapped to a host. To view the contents of a snapshot, you must first clone the snapshot then map the clone to a host.”

Q29. A customer asks you about adding 4-port 1 GbE BaseT connectivity to their Dell EMC Unity XT series array.
What should be your response?

4-port 1GbE BaseT module is supported on Unity XT with the latest Enginuity code

4-port 1GbE BaseT module is provided by the Mezz card on Unity 80 series models

4-port 1GbE BaseT module is not available on Unity XT

4-port 1GbE BaseT module is supported across all Unity models
