EMC VNX Solutions Expert Exam for Implementation Engineers (E20-885) Free Practice Test
Question 1
A customer is planning a CIFS DR test on a VNX. They want to ensure that all production users will be able to access data at the target site in the event of a catastrophic failure at the source site. The source site will remain online during this test.
How can this be accomplished?
How can this be accomplished?
Correct Answer: A
Question 2
You are installing a new VNX and need to implement a Storage Pool on the array. Disks are available and must be set up as follows:
10, 400 GB SSD in R10 (4+4) for the Extreme Performance tier 13, 600 GB + 15K SAS R10 (4+4) for the Performance tier 12, 4 TB NL-SAS R6 (14+2) for the Capacity tier
Disks for FAST Cache, Vault, and unbound disks for sparing, are allocated separately.

How should you lay out the private RAID groups?

Correct Answer: D
Question 3
You are implementing a VNX using AVM, and you cannot create any more dvols from their remaining classic LUNS to create a stripe volume.
What could be a reason for this?
What could be a reason for this?
Correct Answer: C
Question 4
The SQL database and transaction logs have been physically isolated on separate RAID groups. What other actions can be taken to optimize SQL performance?
Correct Answer: A
Question 5
A customer has the following virtualized environment:
One EMC VNX providing thin LUNs to a VMware ESX v4.0 host
Five VMs running critical OLTP systems supported by one or more databases.
The customer previously experienced some out-of-space conditions due to VMDK oversubscription. You recommend they upgrade their virtual environment to vSphere v5.0 to benefit from its VAAI features.
Which VAAI primitive addresses their issue?

Question 6
A customer is testing a DR solution. They want to change the destination file system from read only to read/write and stop the transmission of replicated data.
How can this be accomplished?
How can this be accomplished?
Correct Answer: B
Question 7
A customer creates an incremental SAN Copy (ISC) session for a 200 GB LUN on an EMC VNX. The session fails to start, and the customer notes the RLP (reserved LUN pool) contains 300 MB of storage. What action must be taken to get the session started?
Correct Answer: A
Question 8
Which method of connectivity can be used for storage access from a vRPA to the replication volumes on the VNX?
Correct Answer: B
