Question

1. What is/are the low-cost option(s) available to use on the workstation/laptop/desktop and standalone devices to save and or monitor power usage?

a) Use Kill a watt device

b) Use power save features in the operating systems

c)Both (a) and (b)

d) None of the above

2. What are the ways to cut power used by the IT infrastructure?

a) Data de-duplication; Virtualization

b)Enable sleep features built into the operating system; which takes computer to go to lower power sleep mode

c)Use storage area network [SAN]; use bigger disk drives instead of several smaller size disks

d)All of the above plus monitoring power usage; turn off unused computers and devices; use low-power computers

3. What is net-metering?

a) Practice of selling excess customer generated power back to the utility just like consuming power from utility is called net-metering  

b) Metering computer network power usage

c) Metering Internet power usage

d) Both (b) and (c)

4. What is MAID and what is its benefit?

a) Massive Array of Important Disks; uses low power disks

b) Massive Array of Idle Disks; power on disk as needed, thus saving power

c) Many Arrays of Independent Disks; each can be accessed independently saying power

d) Massive Array of Inexpensive Disks; accessed occasionally

5. Which region has the most expensive electricity cost in the contiguous states of USA?

a) New England

b) Mountain

c) West North Central

d) East South Central

Answer 1

Q 1) Killing a watt device and using the power-saving feature in the operating system will result in reductions of power but the efficient and cost-effective method is Using Power save feature because if you kill a watt device it may result in some performance issue

ANSWER (b) Use power-saving features in the operating systems

Q 2) if we use Enable sleep features built into the operating system; which takes the computer to go to lower power sleep mode, the overall power was taken by the IT sector will reduce significantly.

But if we use bigger disk drives power consumption will be more

de-duplication and visualization will not affect the power usage

ANSWER (b) )Enable sleep features built into the operating system; which takes the computer to go to lower power sleep mode​​​​​​​

Q 3) Net metering is used by the which generate energy from renewable sources and transfer it to the grid. Net metering is mainly used by the user which have a solar panel installed and it transfers excessive power from the user to utility center or distribution

ANSWER (a) Practice of selling excess customer-generated power back to the utility just like consuming power from the utility is called net-metering  ​​​​​​​

Q 4) MAID is defined as a Massive array of the idle disk which is used for the saving of power due to idle condition of a number of the disk.

ANSWER (b) Massive Array of Idle Disks; power on disk as needed, thus saving power
