MS-700 Question #129: Real Exam Question with Answer & Explanation

Question

Your network contains an Active Directory domain. The domain contains 1,000 computers that run Windows 11. Your company uses Microsoft Teams. You need to ensure that the computers can prioritize audio and video during Teams meetings. From the Microsoft Teams admin center, you set Insert Quality of Service (QoS) markers for real-time media traffic to On. What should you do next?

Options

• AFrom Meeting settings in the Microsoft Teams admin center, configure the media port range to use any available ports.
• BFrom Group Policy Management, create a Group Policy setting to specify the DSCP values.
• CFrom the Teams PowerShell module, create a network roaming policy.
• DFrom Meeting policies in the Microsoft Teams admin center, configure the Media bit rate (Kbs) setting.

Explanation

{"question_number": 3, "correct_answer": "B", "explanation": "After enabling 'Insert QoS markers for real-time media traffic' in the Teams admin center, you must use Group Policy Management to create a Group Policy Object (GPO) that specifies the correct DSCP (Differentiated Services Code Point) values for Teams audio, video, and screen-sharing traffic. The Teams admin center setting alone only instructs Teams clients to insert DSCP markers, but the actual DSCP values and port ranges must be defined and enforced at the OS level via Group Policy (specifically using Windows QoS Policy under Computer Configuration). Option A is incorrect because QoS requires specific, defined port ranges-not 'any available ports'-so that policies can target the correct traffic. Option C (network roaming policy) controls settings like network-based meeting mode switching, not DSCP marking. Option D (Media bit rate) limits bandwidth consumption but does not configure traffic prioritization via QoS.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
