MS-721 Question #200: Real Exam Question with Answer & Explanation

Question

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?

Options

• AAssign an SBA policy to the users in Branch1.
• BReregister the SBA with Azure AD.
• CReconfigure the PSTN trunk settings for the SBA.
• DAssign a dial-out policy to the users in Branch1.

Explanation

Users can only use a Survivable Branch Appliance during an internet outage if they have been explicitly assigned an SBA policy; without it, they cannot register to the SBA.

Common mistakes.

• B. Re-registering the SBA with Azure AD addresses an authentication or connectivity issue with the appliance itself and would not extend SBA coverage to users who lack an assigned SBA policy.
• C. PSTN trunk settings on the SBA control the SIP trunk to the carrier and are not the mechanism by which user devices discover or register to the SBA during an outage.
• D. A dial-out policy controls whether meeting participants can dial out to PSTN numbers from meetings and has no relation to SBA registration or branch office survivability.
