NEW QUESTION 6
A customer wants to expand their Dell EMC Unity Hybrid system, which includes a pool of 64 drives in a RAID 5 (4+1) configuration. What is the minimum number of drives needed to expand the pool?

• A. 1
• B. 5
• C. 6
• D. 7

Answer: C

Explanation:
DELL PDF document about dynamic pools: h16289-dell_emc_unity-dynamic_pools.pdf
Page 20-21. The smallest RAID 5 stripe width the system supports is a 4+1. The smallest dynamic pool created with the RAID 5 4+1 configuration is 6 drives. The minimum drive count includes the number of drives specified in the stripe width, plus the hot spare capacity. The hot spare capacity is selected by the user at pool creation, and can either be set to 1 or 2 drives for every 32 drives in the pool.

Answer: D

NEW QUESTION 9
To which bus is the Dell EMC Unity 880F DPE connected?

• A. 49
• B. 89
• C. 99

Answer: D

Explanation:
The DPE on 480/F, 680/F, and 880/F systems is internally connected to Bus 99 which is a separate bus than the first SAS expansion port that is connected to Bus 0. Therefore, the DPE is recognized by the system as Bus 99 Enclosure 0 while the first DAE connected to the first SAS expansion port would be Bus 0 Enclosure 0. This is different than X00/F, X50F, and 380/F systems. Furthermore, this means that the twenty-five drives in front of the DPE for 480/F, 680/F, and 880/F systems are internally recognized as Bus 99 Enclosure 0 Drive 0 – Bus 99 Enclosure 0 Drive 24. In Unisphere, the drives are seen DPE Drive 0 –DPE Drive 24

NEW QUESTION 10
In Dell EMC PowerStore storage, if the remote cluster has multiple appliances, then what automatically chooses the destination appliance for the resource?

• A. Performance Policy
• B. Resource Balancer
• C. Master appliance
• D. Source array

Answer: B

Explanation:
From the POWERSTORE ADMINISTRATION PARTICIPANT GUIDE,
" Resource balancer also considers the the following when placing volumes:
Whether the appliance is offline Appliance failure status Capacity utilization

NEW QUESTION 11
What are characteristics of D@RE on a Dell EMC Unity array?

• A. Impacts array only during implementation Has minimal impact on performance
• B. Does not impact array during implementation Has some impact on performance for a moment
• C. Impacts array for a moment after implementation Has no impact on performance
• D. Does not impact array during implementation Has minimal impact on performance

Answer: D

Explanation:
controller-based D@RE has minimal performance impact for typical mixed workloads, and no impact to other Dell EMC Unity data services due to the level at which the encryption is performed, which is after all data services have been applied.

NEW QUESTION 13
Which Dell EMC Unity feature provides network high availability with active-passive ports when provisioning File storage for a NAS client?

• A. Redundant Interfaces
• B. Preferred Interfaces
• C. Link Aggregation
• D. Fail-safe Networking

Answer: D

Explanation:
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.

NEW QUESTION 14
A customer asks you about the maximum load of their new Dell EMC SC Series array. Which term should you use in response?

NEW QUESTION 15
How are vVol datastores mounted in Dell EMC PowerStore storage during the creation of vVol datastores in the vSphere environment shared by ESXi hosts?

• A. Volume Groups
• B. Storage containers
• C. Storage Groups
• D. VMFS datastores

Answer: B

Explanation:
A storage container is used to present vVol storage from a PowerStore cluster to vSphere. vSphere mounts the storage container as a vVol datastore and makes it available for VM storage. When a PowerStore cluster is used to provide VM storage, user VMs should be provisioned on the vVol datastores. The default storage container is mounted automatically on the nodes of the cluster.
