A Rollback Plan is not being created before the change board approves a change. Hence option A is appropriate.
<h3>
What is the Rollback Plan?</h3>
A rollback plan is a type of recovery strategy that seeks to restore the system to its most recent stable condition. It could be a configuration file reload or a tape restore. The rollback plan serves as an emergency exit strategy to restart the system before the allotted length of time has passed.
A rollback strategy outlines how to actually implement your modification in production and ensure that it functions as planned. Since you'll spend time pondering what must be accomplished in order to succeed, the deployment plan creation process is frequently more beneficial than the plan itself.
Hence, option A is correct.

The formula for finding the net present value is -C0 + [C1 / (1 + r)] + [C1 / (1 + r)²] + [C1 / (1 + r)³].
<h3>What is the net present value?</h3>
The net present value is a capital budgeting method. Net present value is the present value of after-tax cash flows from an investment less the amount invested.
Only projects with a positive net present value should be accepted. A project with a negative net present value should not be chosen because it isn't profitable. When choosing between positive net present value projects, choose the project with the highest net present value first because it is the most profitable.
An advantage of the net present value method of capital budgeting is that it considers the times value of money. A disadvantage of net present value is that it is difficult to estimate the accurate discount rate.

Answer:
$19,215.65
Explanation:
To the determine the amount to be invested, we have to find the present value of $22,000 at 7%
P= FV ( 1 + r) ^-n
FV = Future value = $22,000
P = Present value
R = interest rate = 7%
N = number of years = 2
$22,000(1.07)^-2 = $19,215.65
