Question 1

You have a Microsoft Teams deployment. You have a Teams Rooms on Windows device. Users scan a code on the front of room display to join an ongoing meeting automatically. You need to ensure that the users must manually select Accept on the room console before joining the meeting. Which setting should you add to the SkypeSettings.xml file on the device?

A. false
B. false/AllowRoomRemoteEnabled>
C. false< /QRCodeAutoAcceptProximateMeetingInvitations>
D. false
Show Answer
Correct Answer: C
Explanation:
To require manual acceptance on the Teams Rooms console when users join via QR code, you must disable automatic acceptance of proximate meeting invitations. This is done by adding the XML element <QRCodeAutoAcceptProximateMeetingInvitations>false</QRCodeAutoAcceptProximateMeetingInvitations> to SkypeSettings.xml. Options that specify only a value without the setting name are not valid.

Question 2

You have a Microsoft Teams deployment that contains multiple Teams Rooms on Windows devices. Each device is assigned a Teams Rooms Pro license. You need to create a custom update schedule for a subset of the devices by using the Teams Rooms Pro Management portal. What should you do first?

A. Create a new admin role and grant the Modify permission for inventory management to the role.
B. From the Signal settings, enable Windows Server Update Services (WSUS).
C. Create a new ring named Public Preview.
D. Create a new issue that has a description of MTR_Update_Services.
Show Answer
Correct Answer: C
Explanation:
In the Teams Rooms Pro Management portal, custom update schedules are applied through update rings. Before you can define a schedule for a subset of devices, you must first create a new update ring (for example, a Public Preview ring) and then assign devices to it. Permissions, WSUS settings, or creating issues are not prerequisites for creating a custom update schedule.

Question 3

DRAG DROP - You have a Microsoft Teams deployment. You have the users shown in the following table. You need to recommend add-on licenses. The solution must minimize costs. Which add-on license should you recommend for each user? To answer, drag the appropriate licenses to the correct users. Each license 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.

Correct Answer: User1: Microsoft 365 Copilot User2: Microsoft 365 Copilot
Explanation:
Intelligent meeting recap is a Microsoft 365 Copilot feature. User1 also requires a live summary when joining late, which is provided by Copilot. User2 requires intelligent recap as well, and to minimize cost while meeting all requirements, Copilot is the necessary add-on license for both users.

Question 4

You have a Microsoft Teams deployment. You configure Quality of Service (QoS) to prioritize network traffic for Teams communications. You need to validate the QoS configurations. What should you do?

A. From Microsoft Call Quality Dashboard, review Reliability Reports.
B. Perform a packet capture and validate the source port numbers.
C. From Microsoft Call Quality Dashboard, review Quality of Experience Reports.
D. Perform a packet capture and validate that the packets have DSCP markings.
Show Answer
Correct Answer: D
Explanation:
To validate that Quality of Service (QoS) is correctly configured for Microsoft Teams, you must confirm that traffic is actually being marked and prioritized on the network. This is done by performing a packet capture and verifying that Teams media packets carry the expected DSCP markings. Call Quality Dashboard reports focus on call quality outcomes, not on whether QoS markings are applied, so they cannot directly validate QoS configuration.

Question 5

HOTSPOT - You have a Microsoft Teams deployment. You configure an events policy as shown in the following exhibit. Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: require a predefined question to be answered by attendees. dynamically use peer-to-peer content sharing.
Explanation:
The webinar registration setting is **Standard and required**, which enforces predefined questions. With **Use Microsoft eCDN** set to **Off**, attendees receive content via peer-to-peer delivery rather than an eCDN or SBA proxy.

Question 6

You have a Microsoft 365 subscription that uses Microsoft Teams. You need to ensure that guest users can attend webinars. Which type of policy should you create?

A. meeting
B. app permission
C. messaging
D. event
Show Answer
Correct Answer: D
Explanation:
In Microsoft Teams, webinar-specific controls—such as who can attend webinars, including guest access—are configured through Event policies. Meeting, messaging, and app permission policies do not govern webinar attendance.

Question 7

You have a Microsoft Teams Phone deployment. You plan to deploy Teams Phone devices that will use Android AOSP management. You need to ensure that the devices can be managed by using Microsoft 365. What should you do first?

A. Create an Android Device Administrator compliance policy.
B. From Microsoft Intune, create an AOSP management enrollment profile.
C. Assign a Teams Shared Device license to each device.
D. Disable the Microsoft Intune service plan for new shared devices.
Show Answer
Correct Answer: B
Explanation:
Teams Phone devices that use Android AOSP management must first be enrolled into Microsoft Intune using an AOSP management enrollment profile. Creating this profile is the prerequisite step that enables Microsoft 365 and Intune to manage the devices. Licensing and compliance policies are applied after enrollment, not before.

Question 8

HOTSPOT - You have a Microsoft Teams deployment. You need to recommend a physical device solution for the users in a flexible workspace. The solution must meet the following requirements: • Ensure that the users can sit at any desk and have their phone number follow them. • Ensure that the users can make outbound calls without signing in to a device. • Ensure that the users can sign in to a device directly. • Minimize costs. Which type of device should you recommend, and which license should you assign to the devices? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: Device type: Teams Phone License: Teams Shared Device
Explanation:
Teams Phone devices support hot-desking so a user’s number follows them when they sign in. With a Teams Shared Device license, the phone can also place outbound calls without user sign-in (common area behavior), allows direct sign-in when needed, and minimizes licensing cost compared to user-based licenses.

Question 9

You have a Microsoft Teams deployment that uses Calling Plans. You plan to deploy a Teams-certified contact center. You need to recommend a deployment model for the planned deployment. The solution must meet the following requirements: • Users must be able to manage calls by using the Teams app. • Additional hardware or software must be minimized. • Calls must remain within the Teams platform. • Calls must NOT traverse a SIP trunk. What should you recommend?

A. the Connect model
B. a Direct Routing trunk
C. the Extend model
D. the Unify model
Show Answer
Correct Answer: D
Explanation:
The Unify model embeds native Teams calling experiences directly into the contact center app using Teams SDKs. This allows agents to manage calls within the Teams app, keeps calls entirely on the Teams platform, avoids SIP trunks, and minimizes additional hardware or software. Connect/Extend typically involve external telephony or SIP, and Direct Routing explicitly uses SIP trunks.

Question 10

HOTSPOT - You have a Microsoft 365 subscription that uses Microsoft Teams. You plan to deploy 45 Teams Rooms systems. You need to purchase licenses for the deployment. The solution must minimize costs. What is the minimum number of each license you should purchase? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Show Answer
Correct Answer: Teams Premium: 0 Teams Rooms Pro: 20 Teams Rooms Basic: 25
Explanation:
Teams Rooms Basic is free for up to 25 rooms. With 45 rooms total, the remaining 20 rooms must use Teams Rooms Pro. Teams Premium is not required for Teams Rooms deployment.
