You have an Exchange Server 2013 organization that is integrated with Microsoft Lync Server 2013.
Users report that they fail to make Unified Messaging (UM) calls.
You need to perform an end-to-end test of the UM components.
Which cmdlet should you use?
A.
Test-ExchangeUMCallFlow
B.
Test-CsPhoneBootstrap
C.
Start-UMPhoneSession
D.
Test-UMConnectivity
Explanation:
Use the Test-ExchangeUMCallFlow cmdlet (the UM Troubleshooting Tool) to test call flow between
Client Access servers running the Microsoft Exchange Unified Messaging Call Router service, Mailbox
servers running the Microsoft Exchange Unified Messaging service, VoIP gateways, IP PBXs, Session
Initiation Protocol (SIP) servers and Microsoft Lync Server. The Test-ExchangeUMCallFlow cmdlet can
be used to diagnose configuration errors found in telephony components, Exchange 2010 SP1 or
later or Exchange 2013 Unified Messaging settings, and connectivity issues between on-premises
and hybrid Unified Messaging deployments.
Incorrect answers:
Not B: The Test-CsPhoneBootstrap cmdlet verifies that a user can log on to Skype for Business Server
2015 using a Phone Edition-compatible device.
Not D: Use the Test-UMConnectivity cmdlet to test the operation of a Mailbox server computer
running the Microsoft Exchange Unified Messaging service.Test-ExchangeUMCallFlow

This is similar but different from question #88 so know the difference.
So it looks like test-umconnectivity is just a cmdlet for the mailbox servers. Whereas test-exchangeumcallflow is for all roles.
You want to test the end to end connectivity, so this also includes CAS.
A–w–Test-ExchangeUMCallFlow cmdlet ONLY supports testing of CALL ANSWERING (incoming calls) scenarios. (Users report that they FAIL TO MAKE UM CALLS)
D–r–Test-UMConnectivity cmdlet can be used to test the operation of a Mailbox server and related connected telephony equipment. When you run this cmdlet and include the UMIPGateway parameter, the Mailbox server tests the full end-to-end operation of the Unified Messaging system. This test includes the telephony components connected to the Mailbox server, such as IP gateways, Private Branch eXchanges (PBXs), and cabling.
To perform the following procedures, you must log on to the Mailbox server by using an account that’s a member of the local Administrators group.
