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

  1. Volume Groups
  2. Storage containers
  3. Storage Groups
  4. VMFS datastores

Answer(s): 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.



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

  1. Redundant Interfaces
  2. Preferred Interfaces
  3. Link Aggregation
  4. Fail-safe Networking

Answer(s): 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.



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

  1. Port utilization and load balancing
  2. Cache utilization and hardware bottlenecks
  3. Latency and queue depth
  4. General capacity and active data

Answer(s): D

Explanation:

Considerations for capacity growth
- (click) Overall growth vs active data growth
- (click) Moving or expanding "hot blocks" of active data
- Longer term planning for growth



What is a benefit of restoring data from a Dell EMC Unity snapshot?

  1. Can select which Consistency Group members have data restored
  2. Supports replication to up to 32 remote systems
  3. Enables efficient storage usage with 8 KB block granularity
  4. Does not require additional pool storage

Answer(s): D
