Exam MS-720: Microsoft Teams Voice Engineer Practice Test
MS-720 practice covers Microsoft Teams voice services and the decisions involved in delivering reliable calling. The question bank uses workplace scenarios about call-quality investigation, PSTN connectivity, call handling, shared phones, and network conditions. These topics connect Teams Phone configuration with the user and support tasks needed to place, receive, and troubleshoot voice calls.
Exam overview
About the Exam MS-720: Microsoft Teams Voice Engineer Exam
Voice engineering work involves tracing a call from its user and device settings through Teams call handling and the connection to the public telephone network. Scenarios in this practice bank address PSTN assignment, Direct Routing interoperability with a carrier, call queues, call park retrieval, forwarding, and common-area phone sign-in. Other questions focus on diagnosing quality: reviewing call-level details, comparing affected users to identify a broader pattern, and recognizing variable packet delay as jitter. These decisions require connecting symptoms to the relevant administrative view or configuration rather than treating every call problem as an application issue. The scenarios can help you distinguish user-level calling setup from network or carrier connectivity and identify which Teams capability supports a specific call workflow.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A Teams administrator needs to investigate whether a particular user experienced poor call quality during a specific call. Which resource is most directly suited to reviewing call-level quality details?
Show answer
Correct answer: ACall analytics and the Call Quality Dashboard provide call-focused information that can help diagnose user and network quality issues. Service health is useful for broad service incidents but does not replace call-level diagnostics.
A company is setting up a Teams Phone deployment for users who need to place calls to the public telephone network. Which assignment should an administrator verify for each user, in addition to an eligible license?
Show answer
Correct answer: AA Teams Phone license alone does not establish PSTN connectivity. The organization must provide a supported PSTN connectivity method and configure the user's number and related calling settings as required by that method.
A Teams administrator wants a user to retrieve a call that was placed on hold from another Teams endpoint, such as a desk phone. Which feature is designed for this workflow?
Show answer
Correct answer: ACall park places a call on hold and provides a retrieval code so the call can be picked up from another supported endpoint. Forwarding and simultaneous ring redirect or replicate ringing, while queue overflow controls handling of calls waiting in a queue.
A company is preparing a Teams Phone rollout and wants users to be able to place calls over the public internet. What network consideration is most important to validate for voice quality?
Show answer
Correct answer: AReal-time voice media depends on network paths with sufficient bandwidth and low delay, jitter, and packet loss. The other items do not meaningfully determine the quality of Teams voice media transport.
An organization is onboarding a third-party carrier to provide PSTN connectivity through Direct Routing. Which interoperability component is central to connecting the carrier's telephony network to Teams?
Show answer
Correct answer: AIn Direct Routing, a supported SBC connects the organization's telephony infrastructure or carrier interconnect to Microsoft Teams. Meeting templates, SharePoint, and voicemail policies do not provide PSTN interconnection.
A support team wants incoming calls to ring a group of agents, with callers held until an agent becomes available. Which Teams feature should the administrator configure?
Show answer
Correct answer: AA call queue distributes incoming calls to designated agents and can provide waiting experiences while agents are unavailable. An auto attendant provides caller menus and routing choices rather than managing a waiting line for agents.
A Teams user needs to place and receive PSTN calls from a mobile phone when the Teams app is unavailable. Which user-facing capability can help maintain call reachability by forwarding calls to that phone number?
Show answer
Correct answer: ACall forwarding can redirect incoming calls to another destination, such as a mobile or external phone number, subject to the user's configuration and applicable policies. Call park holds a call for retrieval, busy-on-busy controls handling of additional calls, and delegation lets another person handle calls on the user's behalf.
How to use this practice test
Access is free. A session presents up to 20 random questions from the 50-question MS-720 practice bank, with results shown after the session. Use the scenarios to check how you select diagnostic views and match call requirements to Teams Phone features; review missed items by tracing the underlying call flow or configuration decision.
Preparation tips
- For call-quality scenarios, distinguish call-level investigation from broader user or group comparisons, and identify what each view can reveal.
- Trace PSTN calling through user licensing and assignment, then distinguish Direct Routing's carrier interconnection role from Teams-side call configuration.
- Compare call queue, call park, and forwarding scenarios by the user action each supports: waiting for an agent, retrieving a held call, or reaching another phone number.
- Review network-quality terms such as latency, jitter, and packet loss, and connect each symptom to its likely effect on voice.
- Separate common-area phone requirements from individual-user calling setup, including the purpose of a dedicated shared-device account.
