NEW QUESTION 1
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 2

NEW QUESTION 3
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.

NEW QUESTION 7
When sizing a Dell EMC Unity Hybrid array, what are considerations for growth?

• A. Port utilization and load balancing
• B. Cache utilization and hardware bottlenecks
• C. Latency and queue depth
• D. General capacity and active data

Answer: D

Explanation:
Considerations for capacity growth
(click) Overall growth vs active data growth

NEW QUESTION 8
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 9
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?

• A. Create a volume group of the snapshot.
• B. Create a read/write snapshot of the snapshot
• C. Create a copy of the snapshot
• D. Create a thin clone of the snapshot

Answer: D

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."
