Answer: C
Question #2 (Topic: )
A customer has a large ESX server environment they are considering deploying to XtremIO
for a VDI implementation. To determine a baseline of the environment, you are proceeding
with documenting each servers CPU, NIC, and disk utilization statistics. The customer has
provided you with direct CLI access to the servers to conduct this assessment.
Which utility should be used to monitor these performance parameters?

Question #4 (Topic: )
Which actions are initiated when a snapshot is created on an XtremIO array?
A. Parent object becomes read only and two auxiliary volumes are created
B. Parent object remains writeable and one auxiliary volume is created
C. Parent object remains writeable and two auxiliary volumes are created
D. Parent object becomes read only and one auxiliary volume is created
Answer: A
Question #5 (Topic: )
A customer has recently deployed an XtremIO 20 TB two X-Brick cluster to run an existing
instance of Oracle RAC previously leveraging VNX for back-end storage. The application
environment uses a block size of 1 MB. Multiple tables are in use with the
PARALLEL_DEGREE_POLICY variable set to AUTO.
The customer wants your help with tuning the DB_FILE_MULTIBLOCK_READ_COUNT
parameter for best performance with XtremIO. Which values should be recommended for
tuning the DB_FILE_MULTIBLOCK_READ_COUNT parameter in the Oracle RAC
environment?
