EMC VNX Solutions Specialist Exam for Technology Architects Sample Questions:
Question 1
A customer is planning to add a new VNX array to their ESXi environment. What benefit will the VAAI plug-in provide?
A. Hardware acceleration
B. Virtualmachinefault tolerance
C. Online LUN migration
D. VNX-provided storage capabilities to vCenter
Question 2
DRAG DROP
You are presenting VNX Quality of Service to a customer. The customer would like you to demonstrate how to set up QoS.
In what order would you accomplish this?
Question 3
---
A customer needs to give a host 300 GB of disk space to improve performance. The VNX to be used has three RAID groups available.
RAID group 1 is RAID 5 (4+1) with 240 GB free
RAID group 2 is RAID 5 (4+1) with 220 GB free
RAID group 3 is RAID 5 (6+1) with 250 GB free
The utilization of each RAID group is minimal and all use 300 GB SAS drives. Keeping in mind the best practices, how would you create a metaLUN?
A. Concatenated with 100 GB on RAID group 1, RAID group 2 and RAID group 3.
B. Striped with 150 GB on RAID group 1 and RAID group 2.
C. Striped with 100 GB on RAID group 1, RAID group 2 and RAID group 3.
D. Concatenated with 50 GB on RAID group 1 and 250 GB on RAID group 3.
Question 4
A customer has two IP Replicated VNX systems: VNXA is the Primary system; VNXB is thedisaster recovery (DR)system. VNXA is configured with VDMs containing CIFS servers, has secmap cache disabled, and runs a primary Usermapper. VNXB is configured as a DR target system and runs a secondary Usermapper.
During failover testing, VNXA is failed over and shut down to simulate a site outage. The smallnumber of Linux users that access the CIFS data via NFS find that they no longer have the samepermissions as when accessing from the primary site. Additionally, the UID ownership of many files has changed. On investigation it is found that the secondary Usermapperdatabasecontains far fewer, and different, mappings compared to the primary.
Why would this be the case?
A. The secondary Usermapperdatabasehas become corrupted after failover.
B. The primary Usermapperdatabaseis not replicated to the secondary Usermapper.
C. The DR site must be promoted to become a primary Usermapper on failover.
D. The primary Usermapperdatabasehad not completed synchronizing before failover.
Question 5
A Storage Administrator tries to expand the size of a thin pool LUN in a pool that is oversubscribed by 70%. The operation fails.
What could be causing this issue?
A. A thin pool LUN cannot be expanded.
B. The LUN is participating in a Mirror Group.
C. The pool does not have enough free space.
D. The LUN is still being accessed by a host.
