NEW QUESTION 7
When a remove replication operation is performed on a Dell EMC PowerStore array, what happens to the destination storage resource?

• A. Is deleted
• B. Stays in read/write mode
• C. Stays in read-only mode
• D. Taken offline

Answer: C

Explanation:
"Removing a replication session is initiated on the source system by removing the protection policy from the Volume or Volume Group on the source system. Removing the protection policy from a storage resource results in the following: * The destination storage resource stays in read-only mode."

NEW QUESTION 10
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 12
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.
