MS-740 Troubleshooting Microsoft Teams (MS-740) Certification Sample 4 — Questions and Answers
Question 1: A user's Teams app on Windows keeps signing them out unexpectedly every few hours. Other Microsoft 365 apps remain signed in. What is the most likely cause?
- The Teams cache is corrupted and needs to be cleared
- A conditional access policy is requiring re-authentication for Teams specifically (Correct answer)
- The user's Microsoft 365 license is expired
- Teams is not supported on the user's Windows version
Correct answer: A conditional access policy is requiring re-authentication for Teams specifically
Conditional access policies can target specific applications and enforce session lifetime limits, causing Teams to require re-authentication more frequently than other apps.
Question 2: An organization migrated from Skype for Business on-premises to Teams. Some users report they cannot receive calls from Skype for Business users. What must be configured to allow this?
- Enable Federation in Teams Admin Center > Org-wide settings > External access (Correct answer)
- Assign all users a Teams Phone System license
- Enable Guest access for Skype for Business users
- Configure a SIP trunk between Teams and Skype for Business
Correct answer: Enable Federation in Teams Admin Center > Org-wide settings > External access
External access (Federation) must be enabled in Teams to allow communication with Skype for Business users, both on-premises and online.
Question 3: During a Teams meeting, a presenter's shared PowerPoint slides appear blurry to attendees. The presenter's own view is sharp. What is the most likely cause?
- Attendees need to update their Teams client
- Low network bandwidth on the attendees' side is causing Teams to reduce video quality (Correct answer)
- The presenter is sharing the wrong application window
- Teams has a known bug with PowerPoint rendering
Correct answer: Low network bandwidth on the attendees' side is causing Teams to reduce video quality
Teams dynamically adjusts screen share resolution based on available bandwidth; blurry content for attendees typically indicates insufficient download bandwidth on their end.
Question 4: A Teams administrator wants to audit which users joined a specific meeting and at what time. Which tool provides this information?
- Microsoft 365 Audit Log in the compliance portal (Correct answer)
- Teams Admin Center > Analytics & reports > Meeting usage
- Azure AD Sign-in logs
- Call Analytics for the meeting organizer
Correct answer: Microsoft 365 Audit Log in the compliance portal
The Microsoft 365 audit log records Teams meeting join and leave events, providing a timestamped record of all participant activity for compliance and troubleshooting.
Question 5: A user reports that they are unable to send messages in a Teams channel that they are a member of. Other members can post without issues. What should be checked?
- The user's messaging policy AllowUserChat setting
- Whether the channel is set to read-only by moderators via channel moderation settings (Correct answer)
- Whether the user's Microsoft 365 account password has expired
- Whether the user has a Teams Essentials license
Correct answer: Whether the channel is set to read-only by moderators via channel moderation settings
Channel moderation settings allow team owners to restrict posting to moderators only, which would prevent regular members from sending messages in that channel.
Question 6: A user's auto-attendant in Teams Phone is not routing calls correctly during non-business hours. Calls are going to the main menu instead of the after-hours greeting. What is the most likely misconfiguration?
- The auto-attendant is not assigned a phone number
- The business hours schedule in the auto-attendant configuration is set incorrectly (Correct answer)
- The resource account lacks a Phone System license
- The after-hours greeting audio file format is unsupported
Correct answer: The business hours schedule in the auto-attendant configuration is set incorrectly
Auto-attendants use configured business hours schedules to determine routing; an incorrect schedule causes the system to apply business-hours routing during after-hours periods.
Question 7: A remote user experiences echo during Teams calls. Other participants on the same call do not experience echo. What is the primary cause and fix?
- The remote user's Teams client has a bug; reinstall Teams
- The remote user's speaker volume is too high, causing audio to feed back into their microphone (Correct answer)
- The remote user's network has high latency
- The call server is routing audio incorrectly
Correct answer: The remote user's speaker volume is too high, causing audio to feed back into their microphone
Echo is typically caused by a user's speaker audio being picked up by their microphone; reducing speaker volume or using a headset eliminates the feedback loop.
