Troubleshooting Microsoft Teams (MS-740) — Questions and Answers

Question 1: A sensitivity label applied to a Teams team prevents external sharing. Which feature enforces this?

DLP policy for Teams
Teams privacy settings
Azure AD sensitivity labels with guest access control (Correct answer)
Information barrier policy

Correct answer: Azure AD sensitivity labels with guest access control

Sensitivity labels can be configured to control guest access, preventing external users from being added to labeled teams and channels.

Question 2: A user's Teams presence shows 'Unknown' to colleagues. What is the most likely cause?

Privacy settings set to 'No one can see my presence' (Correct answer)
Teams license is expired
Outlook integration is disabled
Network proxy blocking presence service

Correct answer: Privacy settings set to 'No one can see my presence'

If a user's privacy settings block presence visibility, other users will see 'Unknown' instead of their actual availability status.

Question 3: What maximum number of attendees does a Teams live event support?

500
10,000 (Correct answer)
50,000
1,000

Correct answer: 10,000

Teams live events support up to 10,000 attendees in a standard configuration, with extended limits available for large events.

Audio output device selection in Teams settings (Correct answer)
ScreenSharingMode policy
Microphone permissions in Teams
Audio conferencing license

Correct answer: Audio output device selection in Teams settings

If a user cannot hear others, the audio output device may be set to the wrong device in Teams audio settings.

Question 5: What is the purpose of the Teams Communications Support Engineer role?

Administer Direct Routing settings
Manage Teams policies and configurations
Create and manage Teams phone numbers

Correct answer: View call analytics for all users and read all data in CQD

The Teams Communications Support Engineer role provides read-only access to call analytics and CQD data for all users in the organization.

Question 6: A live event recording is not available 24 hours after the event. What should you check first?

Organizer's OneDrive storage quota
Teams service health in Microsoft 365 admin center
Live event usage report in Teams admin center (Correct answer)
Stream encoding settings

Correct answer: Live event usage report in Teams admin center

The live event usage report shows encoding status and recording availability; processing delays or errors are logged there.

Question 7: What is the effect of setting 'TeamsOnly' upgrade mode for a user?

Skype for Business Online is primary; Teams is read-only
All chats, calls, and meetings use Teams; Skype for Business is disabled (Correct answer)
Teams and Skype for Business coexist
Teams is disabled and Skype for Business handles all communication

Correct answer: All chats, calls, and meetings use Teams; Skype for Business is disabled

TeamsOnly mode routes all incoming chats, calls, and meeting scheduling through Teams, and Skype for Business functionality is disabled for that user.

Question 8: What happens to a Teams meeting recording if the organizer's OneDrive is full?

Recording fails and an error is sent to the organizer (Correct answer)
Recording is saved to SharePoint automatically
Recording is sent to Teams admin center storage
Recording is compressed and saved locally

Correct answer: Recording fails and an error is sent to the organizer

If the organizer's OneDrive is full, the recording fails to save and the organizer receives an email notification about the failure.

Question 9: A user's Teams status is showing as 'Unknown' to colleagues despite the user being actively logged in. What is the most likely cause?

The user's Microsoft 365 license does not include presence
Presence publishing is throttled or the presence service is experiencing an outage (Correct answer)
The user has blocked their colleagues
The user is in Do Not Disturb mode

Correct answer: Presence publishing is throttled or the presence service is experiencing an outage

An 'Unknown' presence status typically indicates a presence service issue, such as throttling or a temporary service outage affecting presence publishing.

Question 10: A user's meeting invites are missing the Teams join link. What is the most likely cause?

User's calendar is set to offline mode
Teams meeting policy restricts scheduling
Outlook add-in for Teams is disabled (Correct answer)
Exchange hybrid misconfiguration

Correct answer: Outlook add-in for Teams is disabled

The Teams Meeting add-in for Outlook must be enabled; if disabled, Teams join links are not automatically added to calendar invites.

Question 11: What minimum upload bandwidth is recommended per user for HD video in Teams meetings?

3 Mbps
500 Kbps
4 Mbps
1.5 Mbps (Correct answer)

Correct answer: 1.5 Mbps

Microsoft recommends 1.5 Mbps upload bandwidth per user to support HD video in Teams meetings.

Question 12: A user reports that calls from specific countries are being blocked. Which feature is responsible?

Geo-fencing in Azure AD
Network topology settings
Country-specific voice routing policy
Outbound calling restrictions in Teams calling policy (Correct answer)

Correct answer: Outbound calling restrictions in Teams calling policy

Outbound calling restrictions in the Teams calling policy can block calls to specific country categories such as premium or international numbers.

Question 13: A Microsoft Teams environment exists in a corporation. Teams with established channels were set up by the sales and support departments. Users from the sales division claim that one of the channels' Files tab is inaccessible. The notification "Item may not exist or is no longer available" appears. You must recognize and fix the problem. What ought you to do?

Recover all the deleted items from the recycle bin of the corresponding Teams site.
Create a separate document library with the same name as the channel.
All of the Above
Revert the renamed folder to the original channel folder name. (Correct answer)

Correct answer: Revert the renamed folder to the original channel folder name.

The 'Files' tab in a Microsoft Teams channel is directly linked to a corresponding folder in the team's SharePoint document library. If this specific folder is renamed within SharePoint, the connection breaks, causing the 'Files' tab to become inaccessible and display an error message. Reverting the folder's name in SharePoint to its original channel-matching name will re-establish the link and resolve the issue.

Question 14: A guest user cannot access a private Teams channel they were invited to. What is the likely cause?

Private channels do not support guest access (Correct answer)
Teams information barrier is active
Guest access is disabled org-wide
The guest lacks an Azure AD account

Correct answer: Private channels do not support guest access

Private channels in Microsoft Teams do not support guest user access; only internal org members can be added to private channels.

Question 15: The emergency address situation must be resolved. What ought to be done?

Add the IPv4 and IPv6 public relay addresses to the trusted IP address list for the tenant. (Correct answer)
Route HTTPS traffic to Microsoft Teams by using a proxy and the proxy IP address.
Add only the IPv4 public relay IP address to the trusted IP address list for the tenant.
Add only the IPv6 public relay IP address to the trusted IP address list for the tenant.

Correct answer: Add the IPv4 and IPv6 public relay addresses to the trusted IP address list for the tenant.

For dynamic emergency calling to function correctly and accurately determine a user's location, the public IP addresses (both IPv4 and IPv6) of the network's internet egress points must be added to the trusted IP address list in the Teams admin center. This allows Teams to identify the network location and associate it with the correct emergency address, ensuring emergency services are routed appropriately.

Question 16: What does a high Round Trip Time (RTT) value in CQD indicate?

Firewall blocking media ports
Network latency between endpoints (Correct answer)
High CPU utilization on client
Codec mismatch

Correct answer: Network latency between endpoints

High RTT in CQD indicates network latency, meaning packets are taking too long to travel between the Teams client and Microsoft's servers.

Question 17: A user reports poor call quality affecting multiple people in the same office. Which Teams admin center tool provides aggregate call quality data across the organization?

Teams activity report
Call Quality Dashboard (CQD) (Correct answer)
Audit log
Usage reports

Correct answer: Call Quality Dashboard (CQD)

CQD (Call Quality Dashboard) provides aggregate, tenant-wide call quality metrics and trending data for identifying systemic network issues.

Question 18: What license is required for a resource account used by a Teams call queue?

Teams Phone Standard
Microsoft Teams Phone Resource Account (free) (Correct answer)
Audio Conferencing add-on
Microsoft 365 E3

Correct answer: Microsoft Teams Phone Resource Account (free)

Resource accounts for call queues and auto attendants require a free Microsoft Teams Phone Resource Account license assigned in Microsoft 365.

Question 19: A Teams tenant admin wants to prevent users from downloading meeting recordings. Which policy setting achieves this?

Disable download permissions on the OneDrive/SharePoint site where recordings are stored (Correct answer)
Set AllowTranscription to False in the meeting policy
Set AllowCloudRecording to False in the meeting policy
Configure SharePoint external sharing to 'Disabled'

Correct answer: Disable download permissions on the OneDrive/SharePoint site where recordings are stored

Teams meeting recordings are stored in OneDrive or SharePoint; restricting download permissions on those storage locations prevents users from downloading the recording files.

Question 20: A Teams channel message containing a credit card number was shared. Which compliance alert would fire?

Communication Compliance alert
Insider Risk alert
DLP policy alert for financial data (Correct answer)
Azure AD Identity Protection alert

Correct answer: DLP policy alert for financial data

A DLP policy configured with the 'Credit Card Number' sensitive information type will detect and alert on credit card numbers shared in Teams messages.

Question 21: What is the maximum recommended packet loss percentage for acceptable Teams audio quality according to Microsoft?

10%
0.5%
5%
1% (Correct answer)

Correct answer: 1%

Microsoft recommends packet loss below 1% for Teams audio; higher values cause noticeable degradation in call quality.

Question 22: A user cannot find the Calls tab in the Teams desktop client. The user has a Microsoft 365 E3 license. What is the most likely reason?

The user is not assigned a Teams Phone (calling) add-on license or calling plan (Correct answer)
The user's IT admin has hidden the Calls tab via app setup policy
The Calls tab is only available in Teams mobile
The user needs to update their Teams client

Correct answer: The user is not assigned a Teams Phone (calling) add-on license or calling plan

The Calls tab in Teams requires a Teams Phone System license and an associated calling plan or Direct Routing; E3 alone does not include calling capabilities.

Question 23: Where are Teams meeting recordings stored by default in Microsoft 365?

OneDrive for Business (organizer's) (Correct answer)
Exchange Online mailbox
SharePoint team site
Azure Blob Storage

Correct answer: OneDrive for Business (organizer's)

By default, Teams meeting recordings are saved to the organizer's OneDrive for Business after the new recording storage model rollout.

Question 24: A Teams dial-in conference number is not working for a scheduled meeting. Participants receive a 'conference not found' message. What should be verified?

Whether the meeting room is booked in Outlook
Whether the meeting organizer has an Audio Conferencing license assigned (Correct answer)
Whether the meeting was created from Teams mobile
Whether participants have the Teams app installed

Correct answer: Whether the meeting organizer has an Audio Conferencing license assigned

Dial-in conferencing requires the meeting organizer to have an Audio Conferencing license; without it, no dial-in number is provisioned and participants receive a conference not found error.

Question 25: A compliance officer needs to export Teams chat messages for legal review. Which feature should you use?

Teams admin center export
Compliance recording policy
Microsoft 365 Message Center
Microsoft Purview eDiscovery (Correct answer)

Correct answer: Microsoft Purview eDiscovery

Microsoft Purview eDiscovery (formerly Compliance Center) allows administrators to search, hold, and export Teams messages for legal purposes.

Question 26: The website contoso.com belongs to Contoso, Ltd. The business registers fabrikam.com as an extra domain. You can use the Microsoft Teams app to arrange a meeting from the contoso.com domain. UserA@fabrikam.com cannot be added as a participant in the meeting. You have to fix this problem. Which three things ought you to do?

Ensure that the Fabrikam.com domain is verified in Microsoft 365.
Set the value of the HiddenFromAddressListsEnabled attribute to False for the user's mailbox.
Assign a Microsoft Exchange license to UserA.
All of the Above (Correct answer)

Correct answer: All of the Above

To ensure UserA@fabrikam.com can be added as a participant in a Teams meeting, several conditions must be met. First, the fabrikam.com domain must be verified in Microsoft 365. Second, UserA needs a Microsoft Exchange license to have a functional mailbox. Third, the `HiddenFromAddressListsEnabled` attribute for UserA's mailbox must be set to `False` to ensure they are discoverable in the global address list. Therefore, all these actions are required.

Question 27: A scheduled Teams meeting shows no dial-in numbers. What is the most likely cause?

DNS SRV records are missing
Meeting policy disables PSTN conferencing
Teams is not federated with the PSTN
User lacks an Audio Conferencing license (Correct answer)

Correct answer: User lacks an Audio Conferencing license

Dial-in conferencing numbers only appear when the meeting organizer has an Audio Conferencing add-on license assigned.

Question 28: A user cannot share their screen during a Teams meeting. Which policy setting controls this?

AllowGuestUser in org-wide settings
AllowExternalAccess in federation settings
AllowPrivateCalling in calling policy
ScreenSharingMode in Teams meeting policy (Correct answer)

Correct answer: ScreenSharingMode in Teams meeting policy

The ScreenSharingMode parameter in the Teams meeting policy controls whether users can share their entire screen or just a single application.

Question 29: A user is set up with Teams Phone but reports that voicemail messages are not being delivered to their email. What should be checked first?

Whether the user has a Calling Plan license
Whether the auto-attendant is configured correctly
Whether the user's Exchange Online mailbox is enabled and accessible (Correct answer)
Whether the user's Teams client is updated

Correct answer: Whether the user's Exchange Online mailbox is enabled and accessible

Teams voicemail is delivered via Exchange Online; if the user's mailbox is disabled, full, or inaccessible, voicemail messages will not be received.
