Answer: B

Explanation:

The Microsoft Connectivity Analyzer (MCA) tool is a companion to the Microsoft Remote Connectivity Analyzer web site. The MCA tool provides administrators and end users with the ability to run connectivity diagnostics for five common connectivity symptoms directly from their local computer.

One of the five symptoms that can be tested using MCA is:

“I can’t log on to Skype for Business on my mobile device or the Skype for Business Windows Store App” C This test checks for the Domain Name Server (DNS) records for your on-premise domain to ensure they are configured correctly for supporting Mobile Skype for Business clients. Also it connects to the Autodiscover web service and makes sure that the authentication, certificate, web service for Mobility is correctly set up.
