MS-720 Question #143: Real Exam Question with Answer & Explanation

Question

You have a Teams Phone deployment. When you review the Server - Client summary reports in Teams, you discover that Wired Inside data is unavailable as shown in the following exhibit. You need to review the monthly and daily trends in the reports. What should you do?

Options

• AFrom the Microsoft Teams admin center, configure the network topology.
• BFrom the Microsoft Call Quality Dashboard, upload the Building data file.
• CFrom the Microsoft Teams admin center, upload reporting labels.
• DFrom the Microsoft Call Quality Dashboard, upload the Endpoint data file.

Explanation

Uploading the Building data file to CQD is correct because CQD requires subnet-to-building mappings to classify calls as "Wired Inside" vs. "Wired Outside." Without this file, CQD has no way to determine whether a call originated from inside a corporate building, leaving that dimension blank in the reports - which is exactly the symptom shown in the exhibit.

Why the distractors fail:

• A - Configuring network topology in the Teams admin center supports Location-Based Routing and emergency calling, not CQD building classification.
• C - Reporting labels in the Teams admin center improve call health visibility within Teams admin center reports, but they do not feed the CQD building/subnet mapping needed for "Wired Inside" data.
• D - The Endpoint data file in CQD maps device identifiers (e.g., machine names) to custom attributes, not network locations, so it cannot enable building-level classification.

Memory tip: "Building data = building awareness." CQD needs the Building data file to know which subnets are inside your buildings - no file, no "Inside" data. Think of it as giving CQD a floor plan of your network.
