In order to import VMs from an ESX/ESXi server using Unisphere, which action is required?
Load an acceptable certificate from the vCenter server or ESXi server.
Install Unisphere Host Agent on the VM.
Install Unisphere Host Agent on the ESX/ESXi server.
Register the VM on the array.
A customer logs in to Unisphere as an administrator and tries to delete a storage group, but is unable to do so. What must the customer do to delete this storage group?
Make sure no hosts are connected to the storage group
Make sure no LUNs are present in the storage group
Delete the storage group from Navisphere Secure CLI
Enter Engineering mode to delete the storage group
A customer has a VNX system that uses only RAID 5 configured as 4+1 groups. The VNX model supports a maximum of 250 drives. They intend to use Clones for local replication and backups. What is the size of the largest Pool they can create?
An environment contains five LUNs of 65 GB each, and five LUNs of 35 GB each. Each of the LUNs will have a SnapView Snapshot created on it. What is a recommended configuration of the Reserved LUN Pool?
20 thick LUNs of 5 GB each
20 thin LUNs of 5 GB each
5 thick LUNs of 13 GB each, and 5 thick LUNs of 7 GB each
10 thin LUNs of 6.5 GB each, and 10 thin LUNs of 3.5 GB each
When the Access Logix database is licensed and enabled, where will it be cached?
On a Windows host with Emulex HBAs installed, which tool is used to view target WWPNs?
HBAnywhere / ONECOMMAND
What is the slice size for a LUN in a storage pool?
What Windows component runs a supported time service for a CIFS server by default?
Which feature of VSI can be used for block storage on a VNX?
VM clones with View
A customer is planning to add a new VNX array to their ESXi environment. What benefit will the VAAI plug-in provide?
VNX-provided storage capabilities to vCenter
Online LUN migration
A customer is trying to understand the relationship between file systems, VNX SnapSure checkpoints, bitmaps, and blockmaps. They want to know the number of blockmaps on a file system. How many blockmaps are available per file system?
As many as there are checkpoints
As many as there are file systems
One per 20 GiB of data
One for all file systems per VDM
A system administrator has reported degraded performance with several of the applications that run on an EMC VNX. After reviewing the performance data on the array, you discover that all performance issues are related to one RAID 5 RAID Group. Specifically, this RAID Group is performing 50 percent fewer IOPS than before. What is the most likely reason for this issue?
RAID Group is rebuilding
RAID Group is trespassed
Write cache is not configured
Read cache is not configured

E20-545 VNX Solutions Specialist Exam for Technology Architects
~ 60 Questions
Specialist – E20-545
This exam is one of two qualifying exams for the EMC Technology Architect for VNX Solutions – Specialist track.
This exam focuses on the knowledge and skills needed for the planning and design of the EMC VNX series storage systems. Design requirements will cover Block (FC, iSCSI,
FCoE), File (NFS, CIFS) and ESXi environments. The exam will also encompass network considerations, host implementation practices, designing file systems, local protection, and planning and considerations for a SAN in Windows and Linux environments.
EMC provides free practice tests to assess your knowledge in preparation for the exam. Practice tests allow you to become familiar with the topics and question types you will
find on the proctored exam. Your results on a practice test offer one indication of how prepared you are for the proctored exam and can highlight topics on which you need to study and train further. A passing score on the practice test does not guarantee a passing score on the certification exam.
