Question
Your company develops an app for iOS. All users of the app have devices that are members of a private distribution group in Microsoft Visual Studio App Center.
You plan to distribute a new release of the app.

A successful IOS device build will produce an ipa file. In order to install the build on a device, it needs to be signed with a valid provisioning profile and certificate.
To sign the builds produced from a branch, enable code signing in the configuration pane and upload a provisioning profile (.mobileprovision) and a valid certificate (.p12), along with the password for the certificate.
https://docs.microsoft.com/en-us/appcenter/build/xamarin/ios/When distributing an iOS app, you need to sign it with a certificate before uploading it to the App Store or a distribution service such as Microsoft Visual Studio App Center. This certificate verifies that the app was created by a trusted source and has not been tampered with.
In this scenario, all users of the app have devices that are members of a private distribution group in App Center, which means that the app will be distributed directly to these users rather than being made available publicly in the App Store.
To distribute a new release of the app from App Center, you will need to upload a certificate file to App Center. The type of certificate file you need to upload depends on how you have set up your app's code signing process.
The possible answers are:
A. .cer - This file type is a public certificate, which is used to verify the signature of a signed file. It does not contain the private key needed to sign an app, so this is not the correct answer.
B. .pfx - This file type is a PKCS#12 certificate, which includes both a private key and a public key. This file type can be used to sign an app, so it is a possible correct answer.
C. .p12 - This file type is similar to .pfx and can also include both a private key and a public key. It is often used interchangeably with .pfx, so this is another possible correct answer.
D. .pvk - This file type is a private key file used for code signing on Windows platforms. It is not used for iOS code signing, so this is not the correct answer.
In summary, the correct answer to this question is either B (.pfx) or C (.p12), depending on the specific certificate file that was used to sign the app.
