Q1MS-721
Show answer
Correct answer: A. Create a voice route that matches only U.S. phone numbers, sets the priority to 1, and references the New York City gateway., C. Create a voice route that matches only U.S. phone numbers, sets the priority to 2, and references the Calgary gateway.

You prepare two voice routes that use the same number pattern matching U.S. phone numbers.
When you associate the priority 1 route with the New York City SBC, it is normally selected first.
By associating the priority 2 route with the Calgary SBC, it serves as a backup when the New York City SBC is unavailable.
A wildcard route would also target non-U.S. numbers and exceed the requirements, so it is not appropriate.
When multiple routes match, they are tried in order starting from the route with the lowest priority value.

Q2MS-721
Show answer
Correct answer: C. An emergency call routing policy

An emergency call routing policy lets you define an emergency dial string and an emergency dial mask.
When you set the emergency dial string to 911 and the emergency dial mask to 9911, 9911 is translated to 911, identified as an emergency call, and sent to the specified PSTN route.
An emergency calling policy mainly controls the notification behavior toward security personnel and does not perform number translation.
An outbound PSTN number translation rule shapes the number format passed to the SBC in Direct Routing and cannot be used to identify an emergency call.

Show answer
Correct answer: Invite attendees -> Organizer / Moderate the Q&A -> Presenter / Start and stop the live event -> Producer

The organizer creates the event, sets attendee permissions, and sends invitations, so the organizer is required for invitations.
Moderating the Q&A can also be performed by a presenter, so the presenter, which has fewer privileges than the producer, is the least-privileged role.
A producer is required to control the broadcast stream and to start and stop the live event.
Therefore, you assign the organizer for invitations, the presenter for the Q&A, and the producer for start and stop.
Note that Teams live events are being retired on June 30, 2026, and migration to the successor, Teams town halls, is required.

Show answer
Correct answer: D. In the Microsoft Call Quality Dashboard, select “Upload tenant data” and upload a CSV file that includes all network sites.

The CQD location-enhanced reports identify each network site based on the uploaded subnet and building information.
You cannot combine information from multiple building data files within the same effective period.
When you add a new site, you must re-upload a complete CSV file that includes both the existing sites and the new site.
Network Planner is a feature for modeling network requirements and does not update the CQD location information.
Therefore, an additional upload of a CSV that includes only the new site cannot meet the requirement.

Q5MS-721
Show answer
Correct answer: A. Emergency calling, E. Call forwarding

With the SBA at the time this question was written, dynamic emergency calling (E911) and call forwarding settings were not available during an internet outage, so the expected answers are A and E.
Media bypass is a prerequisite configuration for the SBA to function and flows media locally between the client and the SBC, so it is not C.
Note that in the current Microsoft Learn, basic emergency calling is possible with only location sharing restricted, and call forwarding to a single phone number or to a Teams user is also supported.
Therefore, note that under the current specification the premise of this question does not hold as-is.

Integration solution

Integration type

Show answer
Correct answer: Teams Contact Center / Extend model

Notifying callers of their queue position and listening to or barging in on in-progress calls are features of Teams Contact Center, which manages agents and supervisors.
The Extend model integrates with Teams by using an Azure bot, the Teams Graph API, and the cloud communications API of Microsoft Graph, and does not require Direct Routing.
The Connect model uses a certified SBC and Direct Routing, so it does not meet the requirements.
Currently, a Unify model based on Azure Communication Services has also been added, but the Extend model is appropriate for this question.

Q7MS-721
Show answer
Correct answer: A. Create a new emergency call routing policy., F. Assign an emergency call routing policy to the users in the Brisbane office.

To send emergency calls through a specific SBC, you create an emergency call routing policy that associates a PSTN usage and a voice route that use SBC2.
Then, by assigning this policy only to the Brisbane users, you can route only the emergency calls of the targeted users through SBC2.
An emergency calling policy controls how security personnel are notified and external location lookup, and it does not specify the SBC path to use.
Therefore, creating a new emergency call routing policy and assigning it to the Brisbane users are the correct answers.
Assigning a dial plan or an emergency calling policy does not contribute to specifying the route.

Name Type
Research Security
Marketing Distribution
Name Custom
Global (Org-wide default) No
Policy1 Yes
Policy2 Yes
Rank Group Assigned policy
1 Marketing Policy2
2 Research Policy1
Show answer
Correct answer: B. Policy2 only

User1 belongs to both Research, which is assigned Policy1, and Marketing, which is assigned Policy2.
When a user inherits the same type of policy from multiple groups they belong to, the one with the highest group policy assignment rank takes effect.
Because a lower rank number means higher priority, Policy2 assigned to Marketing at rank 1 is applied.
When a user inherits a custom policy from a group, the global policy is not used together with it.
Note that both security groups and distribution lists can be used for group policy assignment.

Q9MS-721
Name Date
Emergency 2024/01/01 – 2024/01/02
Year-end and new-year holiday 2022/12/23 – 2023/01/08
Outage notification 2023/01/18 – 2023/01/19
Statement Yes No
When a caller places a call on January 1, 2024, the call is forwarded to voicemail.
When a caller places a call on January 18, 2023, the call is automatically forwarded to T-AA.
When a caller places a call on December 25, 2022, a greeting message is played to the caller.
Show answer
Correct answer: Statement 1 “No” / Statement 2 “No” / Statement 3 “Yes”

January 1 applies the emergency holiday flow, but the forwarding target is an external phone number, not voicemail.
Therefore, statement 1 is “No.”
The outage notification on January 18 plays a menu, and forwarding to T-AA requires the caller to press “1,” so it is not an automatic forward, and statement 2 is also “No.”
December 25 falls within the year-end and new-year holiday period, and the configured greeting is played before the call is disconnected, so a greeting message is played and statement 3 is “Yes.”
In an auto attendant, after the greeting is played, one of the following is performed: disconnect, redirect, or play a menu.
Set up – Auto attendant
Set up – Holidays

Q10MS-721
Show answer
Correct answer: B. Add a greeting message., C. Configure call routing.

To guide callers with an auto attendant and forward them to the appropriate recipients, you configure a greeting message to play to callers and call routing to specify the forwarding targets and menu.
There is no requirement to handle calls differently during and outside business hours, and there is no requirement to distribute incoming calls to multiple agents in sequence, so business-hours flows and a call queue are not needed.
A resource account is required when calling the auto attendant directly from a phone number, but this question does not require creating one, so the correct answers are B and C.
Set up – Auto attendant
Manage – Resource accounts for Teams phone agents, auto attendants, and call queues
