Question 2 of 300

You have a Teams Phone deployment that uses Direct Routing on a single Session Border Controller (SBC).

Users report that outbound PSTN calls are failing, but inbound PSTN calls are successful.

When you review the SBC logs, you discover that Microsoft is responding to SIP option requests, but is NOT sending SIP option requests.

What is the cause of the issue?

Show answer

Correct answer: A

The online PSTN gateway being disabled would result in outbound PSTN calls failing while still allowing inbound PSTN calls, as the gateway needs to be operational to handle outbound call routing.

Question 3 of 300

The sales department at your company needs to route a call to multiple users and have calls route differently after business hours.

Which two features should you implement? Each correct answer presents part of the solution.

Show answer

Correct answers: A, D

To achieve the requirement of routing calls to multiple users and having calls route differently after business hours, 'call queues' and 'auto attendants' should be implemented. Call queues allow the sales department to distribute incoming calls to multiple users, ensuring that calls are handled in an orderly manner. Auto attendants can manage calls by providing automated responses and routing options based on the time of day, allowing the system to route calls differently after business hours.

Question 4 of 300

DRAG DROP -

You have a Microsoft Teams Phone deployment.

You need to create two call queues named CQ1 and CQ2. The solution must meet the following requirements:

CQ1 must balance incoming calls so that each call agent receives the same number of calls

Calls received by CQ2 must ring all call agents simultaneously

What should you configure for each requirement? To answer, drag the appropriate routing methods to the correct requirements. Each routing method may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

Question 5 of 300

You have a Microsoft Teams Phone deployment.

You are deploying Direct Routing by using a certified Session Border Controller (SBC). The FQDN of the SBC is sbc1.contoso.com. You use signaling port 5067.

You cannot place calls and receive an error message in the Microsoft Teams admin center as shown in the following exhibit.Exam MS-721: Question 5 - Image 1

What is a possible cause of the issue?

Answer choices
Show answer

Correct answer: D

The issue outlined in the question is related to TLS connectivity status being inactive, which indicates a problem with the secure connection between Microsoft Teams and the certified Session Border Controller (SBC). An inactive TLS connectivity status typically points to problems with the SSL/TLS certificates used by the SBC. Specifically, the SBC might be missing required root certificates, such as Baltimore or Digicert root certificates, which are essential for establishing a trusted TLS connection. Without these root certificates, the SBC cannot properly authenticate and encrypt the signaling traffic, leading to call placement issues. Therefore, ensuring the correct root certificates are present on the SBC is crucial to resolving this problem and establishing an active TLS connection.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla

The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
