To manage end-user iOS devices, you need to configure an Apple Push Certificate, which allows Google to communicate with your devices and enforce security policies1. The certificate expires annually, so you need to renew it before it expires1. You should use a work address that can be accessed in the future, because you will receive email notifications from Apple when the certificate is about to expire1. The other options are incorrect because:
There is no option to "enforce management on iOS devices" under "company owned devices" in the Admin console2.
You cannot select "certificate never expires" when configuring an Apple Push Certificate. The certificate always expires after one year1.
There is no option to enable the Apple Push Certificate connector in the Admin console. You need to download the public key from Google and upload it to Apple Business Manager or Apple School Manager2.
