authentication - answering phone
you are called on your mobile phone for voice authentication.
Is this:
something you have and something you are ?
something you do and something you are ?
Thanks!

application black listing ?
application white listing ?
both of the above answers prevent unauthorized apps from being installed so its confusing.
Can it not be that under application white listing policy, this application is not present?
Thanks!
Voice Biometrics over the phone is something that exists. Biometrics are definitely something you are.
Your mobile phone is something assumed to be something you have. It's a little weaker as a token, because phone numbers can be forwarded away from a specific device. But mobile phones are used as tokens.
The question I would have is how reasonable is it to assume that voice biometrics are in place. It could be that they are calling your mobile phone and asking for a pass phrase (something you know) which isn't analysed for biometrics.
If biometrics are being used, and you are forced to choose between the two answers, then something you are is most reasonable. But in fact all three come into play normally as the biometric system generally uses the same phrase for accurate results and might not prompt.
It's a good "thinking question" but not a good multiple choice exam question.
On a multi-choice, white listing is the best answer. The implication is that only specific known programs are on the whitelist. This would mean "new" software is not likely to make it on the whitelist.
