Answer:
You need to split the traffic to your test version.
Explanation:
Google app engine has a built-in feature that allows you to split a small fraction of your traffic to your test version.
You can split traffic using an IP address, so when the app receives a request, it can hash the Ip to a value between 0 to 999, and use it to re-route the request.
This way you don't need to stop your service during your tests and also avoid any risk involved with it.

Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720
