EMC E20-814 : Practice Test
Question No : 1
A storage administrator is baselining performance for a new server attached to an EMC
Symmetrix VMAX array. The server has two Fibre Channel HBAs each connected through
separate fabrics to two FA ports on the Symmetrix.
 
 
The administrator is looking at the Director and Port statistics in Performance Manager.
Every day there are several hours where the "Port % Util" statistics increase noticeably but
the "I/O per sec" and "Dir % Util" does not change significantly.
 
 
Which type of workload change could explain this situation?
 
 
A. Size of the I/Os increased during that period 
B. Size of the I/Os decreased during that period 
C. Workload shifted from heavy reads to heavy writes during that period 
D. Workload shifted from heavy writes to heavy reads during that period 
 
Answer: A
 
 
Question No : 2
Four DRV devices are configured in an EMC Symmetrix DMX array. As per current
settings, a maximum of four simultaneous swaps and eight swaps per day are allowed in
the Symmetrix. Optimizer analyzes the back-end I/O and decides to swap.
 
 
How many swaps are allowed at the same time?
 
 
A. 1 
B. 2 
C. 4 
D. 8 
 
Answer: B
 
 
Question No : 3

A company needs to comply with data-at-rest security on a server currently in use and
connected to an EMC Symmetrix VMAX. 
 
 
Which security feature will satisfy this requirement?
 
 
A. PowerPath Encryption 
B. Access Control 
C. RSA enVision 
D. IPSec 
 
Answer: A
 
 
Question No : 5
EMC Symmetrix VMAX devices 0AB and 019 are allocated to a UNIX server: 
 
Device 0AB is a two-member meta with a capacity of 50 GB
Device 019 is a standard device with a capacity of 100 GB
 
The storage administrator found that the utilization of device 019 is much higher than
device 0AB. How is the write pending limit allocated?
 
 
A. Device 0AB write pending limit is two times the write pending limit of device 019 
B. Device 019 write pending limit is two times the write pending limit of device 0AB 
C. Device 019 utilization is higher, so the write pending limit of device 019 will be higher
than device 0AB 
D. Both devices will have the same write pending limit 
 
Answer: A

Question No : 8
A company has decided to change the multi-path policy for all of the disks attached to their
ESXi hosts. The environment consists of 16 ESXi hosts with 84 LUNs connected to each
host.
 
 
Since the multi-path policy is applied at the LUN level, changing the policy is going to prove
challenging. Thousands of changes will have to be made which will be time consuming.
 
 
What is the best way to make the necessary changes?
 
 
A. Install VSI Path Management and change the policy for each host 
B. Use VMware Update Manager to propagate the changes to each host 
C. Use the vSphere client to edit the policy for each LUN on each host 
D. Write a custom script to change the policy for each LUN on each host 
 
Answer: A

A storage administrator is planning to implement Dynamic Cache Partitioning (DCP) on an
EMC Symmetrix VMAX array. There are five applications running on hosts attached to this
array. The administrator wants to ensure that none of these applications have any effect on
each other due to cache conflicts.
 
 
Which steps need to be completed to configure DCP?
 
 
A. 1. Create 5 new Dynamic Cache Partitions 
2. Define Target%=20 for each partition 
3. Define Min%=20, Max%=20, and Donation Age= 3600 seconds for each partition 
4. Enable Cache Partitioning 
B. 1. Create 5 new Dynamic Cache Partitions 
2. Define Target%=20 for each partition 
3. Define Min%=0, Max%=100, and Donation Age= 0 seconds for each partition 
4. Enable Cache Partitioning 
C. 1. Create 5 new Dynamic Cache Partitions 
2. Define Target%=20 for each partition 
3. Define Min%=0, Max%=100, and Donation Age= 3600 seconds for each partition 
4. Enable Cache Partitioning 
D. 1. Create 5 new Dynamic Cache Partitions 
2. Define Target%=15 for each partition 
3. Define Min%=15, Max%=15, and Donation Age= 0 seconds for each partition
