Exam MS-721 topic 1 question 125 discussion

The Survivable Branch Appliance (SBA) provides a local gateway for users when there is a disruption in the internet connection to the cloud, ensuring that users can still place and receive PSTN calls. However, for a user to take advantage of the SBA during such an outage, they need to be assigned the appropriate Survivable Branch Appliance (SBA) policy, which is done using the Grant-CsTeamsSurvivableBranchAppliancePolicy cmdlet. This policy ensures that the user is registered to the SBA in case of an internet failure, allowing them to make and receive calls through the local appliance.
