Section A: Quick Questions
Q1
A — Something you know
Q2

PIN = 4829 → Something you know: a knowledge factor
Q2
scan(fingerprint) → Something you are: an inherence factor
Q3
Something you have is a possession factor, like a phone or a key → factor = phone
Q4
Something you know is a knowledge factor, like a password → factor = password
Q5
fingerprint = something you know → A fingerprint is part of your body, so it is something you are (inherence), not something you know.

Q1
C — A fingerprint is something you are (inherence), not something you know. The line should be fingerprint = are.
Q2
C — A PIN is something you know and a fingerprint is something you are. The line should be factors = know + are.
Q3
A — A phone is something you have, not something you know. The know line should list password, PIN.
Q4
A — A password is something you know, not something you have. The have line should list phone, key card.
Q5
D — A PIN is something you know, the same type as a password, so it would not add a new factor type. The line should check the phone code (something you have).
