I have doubt in this question (mentioned below), May be you guys can clarify please.

Callback to a landline phone number is an example of what type of factor ?

A - Something you know.

B - Somewhere you are.

C - Something you have.

D - Something you are.

I selected "A" & came to know that its wrong with the explanation mentioned below -

A callback to a landline phone number is an example of a "Somewhere you are" factor because of the fixed physical location of a wired place. A callback to a mobile phone would be a "Something you have" factor.

** I know there are 3 types of authentication are there - Something you know, Something you have and Something you are. Is there anything like "Somewhere you are" ?
