I tested this by turning off Cellular and WiFi to my phone then used the one-time password code from the Microsoft Authenticator app on my phone and it worked, verification code from Microsoft Authenticator App is the correct answer

Selected Answer: D

B,C Aren't valid, neither is push notification due to no external access, so only valid choice is D. However this is assuming they've already had previously downloaded, added, scanned the QR code and set MFA from a location the has WIFI/external access. This question has cropped up repeatedly with different answers, and many discussions....

"While working from the remote locations, the users connect their laptop to a wired network that has internet access." The users have internet access but only from their laptops. The reason why B and C are not correct is because they are not valid MFA verification options.

the D solution is not valid, if there is no phone connectivity (you have to validate a code at laptop screen, well but where this code comes from ?) the laptop is connected but not the phone and the authenticator app can be installed only on mobile, you can't find it on the Windows (10-11) store. Windows Hello should be the only solution, not D, the code from Authenticator is not a solution here. https://support.microsoft.com/en-us/account-billing/download-and-install-the-microsoft-authenticator-app-351498fc-850a-45da-b7b6-27e523b8702a Install the latest version of the Authenticator app, based on your operating system: 1 - Google Android. On your Android device, go to Google Play to download and install the Authenticator app. 2 - Apple iOS. On your Apple iOS device, go to the App Store to download and install the Authenticator app.

oups my bad D solution is right as you can install the authenticator App from the windows store so you can validate the code, everything is fine :) https://www.microsoft.com/en-us/p/microsoft-authenticator/9nblgggzmcj6?activetab=pivot:overviewtab

i've made a test, the authenticator app installed on windows 10 device redirect calls to mobile, so if you don't have connectivity to your phone the call to authenticator will fail (ans no code will be sent to your Windows 10 device) so Solution A or D is the same the authenticator call could not end, as far as i see only Windows Hello for business is a solution

after test effectively you do not need any connections from your phone (no wifi or data) to get a code and validate it it works https://support.microsoft.com/en-us/account-billing/common-questions-about-the-microsoft-authenticator-app-12d283d1-bcef-4875-9ae5-ac360e2945dd So answer D is correct

Wouldn't Email be a valid option? If they are hardwired on their laptop and have internet connectivity at the time of MFA, email would be valid... Technically would be B or D, kind of a dumb question.

Disregard, i'm a dumb dumb. Of course, there is no "Email" Azure MFA option. Answer is D
