Microsoft MS-721 Exam Practice Questions (P. 2)

GPT

To ensure that the user [email protected] can call international numbers using Microsoft Teams Phone and Direct Routing, a "voice routing policy" must be applied to the user's settings. This type of policy is crucial because it specifically controls the capability of users to utilize Direct Routing, enabling the segmentation of call routes based on numbers or explicitly allowing international dialing, which differs from generally managing Teams features, user calling options, or caller IDs. Thus, B) a voice routing policy is the correct approach to meet the specified requirements of enabling international calls through Direct Routing.

GPT

To kick things off in analyzing Call Quality Dashboard data on Microsoft Power BI for a Teams Phone deployment utilizing Direct Routing, you need to first install the Power BI Connector for CQD. This connector is crucial as it enables interaction between Power BI and the CQD, facilitating data extraction and report generation specifically tailored to analyzing Direct Routing PSTN calls.

GPT

A major point to consider in resolving the Teams Phone issue with external calls is the voice routing policy assigned to the user. If a user has the wrong policy assigned to them, they would be restricted from making external calls while still being able to use the dial pad for internal communications. This aligns perfectly with the problem described. It's key to regularly check and ensure that users have the appropriate policies in place for their required level of call access. Reviewing and updating these could rectify such issues without affecting basic functionalities like the dial pad visibility or internal call capabilities.

GPT

The correct steps to get a new default dial-in number with a 718 area code involve, firstly, searching for numbers by using the 718 area code itself. Secondly, since no additional location data is defined in Teams, obtaining a dedicated conference bridge with a toll number is essential to establish the bridge effectively. It's important to specify the type of number to align with the requirements—hence the selection of a toll number rather than a toll-free, to ensure cost efficiency and functionality within the desired geographic scope.

GPT

For an optimal Microsoft Teams Phone deployment in a collaboration room, you should opt for either Microsoft Teams Rooms on Windows or Microsoft Teams Rooms on Android. These options fulfill all specified requirements, notably supporting video, HDMI content ingestion, one-touch meeting joins, and the ability to initiate meetings directly within the room. Other device options like Teams displays and Teams panels won't cover all these functionalities as they're limited in these specific capabilities.

GPT

To ensure high reliability in a Microsoft Teams Phone deployment using Direct Routing, configuring voice routing policies for each office and deploying a highly available Session Border Controller (SBC) pair in each location are critical recommendations. Each office having its own routing policies enhances efficiency by enabling local call routing, reducing latency, and potentially reducing costs. Additionally, deploying a highly available SBC pair in each office secures the infrastructure against hardware failures, network issues, and other disruptions, maintaining continuous telephony service for all users. This approach maximizes uptime and resilience for the telephony system.

GPT

Reviewing the Quality of Experience Reports in the Microsoft Call Quality Dashboard provides a broad overview of call quality trends, but it may not give the detailed breakdown of SBC SIP errors needed to troubleshoot specific issues with outbound PSTN calls. For a more detailed analysis, Endpoint Reports in the Microsoft Call Quality Dashboard are preferable as they offer insights into individual calls and can pinpoint SIP errors at the SBC level, which are likely causing the call failures. While the Quality of Experience Reports do offer valuable data, they might not be as useful for this specific troubleshooting need.

GPT

Absolutely, for setting up Direct Routing in Microsoft Teams, three components are vital: a public DNS mapping for the Session Border Controller (SBC), a certified SBC, and specific firewall configurations. Importantly, the firewall must allow TCP signaling, specifically through port 5061, which is fundamental for SIP (Session Initiation Protocol) connections to Teams. Ensure these elements are well-configured to enable effective communication between your on-premises network and Microsoft Teams over the Public Switched Telephone Network (PSTN).
