Answer 1

1. (C) SMI-S

SMI-S are industries specified specification used to describe and communicate with storage devices for various management function.

2.( A)

Number of free SAN ports is not tracked as part of storage capacity reporting .

3. (A) 10:1

A ratio of 10:1 means 90% saving that is 10 TB of data can be backed up by 1 TB of physical storage capacity.

4. (C) Reports with data points every minute

5.(A) Perfmon

Perfmon is a windows monitoring tool that can graph and log performance metrics for specific processes which is used to measure the memory usage of a test stand process , display this information on a graph ,and save the data to a log file .

7. (A) SNMP

SNMP is most widely protocol used for monitoring the status and health of a network attached device .

8.(A) IOPS

Input output per second measure number of read and write operations per second and it is the biggest killer performance in storage environment .

10.( C) 50% saving

50% saving have deduplication ratio of 2:1.
