Collaboration Communications Systems Engineer — Question 167

You have a branch office named Branch1 that contains a Survivable Branch Appliance (SBA) in Microsoft Teams.

You have a Teams Phone deployment.

A limited number of users in Branch1 report that when the internet connection to the office fails, they cannot make calls by using Teams.

You need to ensure that all the users in Branch1 can make calls in the event of an internet outage.

What should you do?

Answer options

• A. Assign an SBA policy to the users in Branch1.
• B. Reregister the SBA with Azure AD.
• C. Reconfigure the PSTN trunk settings for the SBA.
• D. Assign a dial-out policy to the users in Branch1.

Correct answer: A

Explanation

Assigning an SBA policy to the users in Branch1 allows them to utilize the Survivable Branch Appliance for call functionality even when the internet is down. The other options do not address the immediate need for call functionality during outages: re-registering the SBA or changing PSTN trunk settings does not ensure call capabilities, and a dial-out policy is not relevant in this scenario.
