You have an Exchange Server 2013 organization that has Unified Messaging (UM) enabled for all
mailboxes. The organization is configured to use an IP gateway to connect to a legacy PBX.
An administrator recently performed some configuration changes. After the changes, users report
that their voice mail is no longer being delivered to their Exchange Server mailbox. The users do not
report any other problem.
You need to identify which configuration change causes the issue.
Which cmdlet should you run?
A.
Test-UMConnectivity
B.
Test-CsExUMConnectivity
C.
Test-ExchangeUMCallFlow
D.
Test-CsExUMVoiceMail
Explanation:
Use the Test-UMConnectivity cmdlet to test the operation of a Mailbox server computer running the
Microsoft Exchange Unified Messaging service.
Two diagnostic tests are designed to test the operation of the Microsoft Exchange Server 2013
Mailbox server software (mode 1) and the operation of the whole system that includes the
connected telephony components (mode 2). The 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. If the
UMIPGateway parameter isn’t specified, the Mailbox server tests only the operation of the Unified
Messaging components that are installed and configured on the server.
Incorrect: Not B: Test-CsExUMConnectivity Verifies that a test user can connect to Exchange Unified
Messaging. This cmdlet was introduced in Lync Server 2013. Not C: Test-ExchangeUMCallFlow Use
the Test-ExchangeUMCallFlow cmdlet 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.
An important thing to consider, any cmdlet that has cs in it is usually a lync cmdlet.
This question has nothing to do with lync as you are not even connecting exchange to lync (you have a legacy PBX). B and D can be ruled out straight away.
And there is no mentioning of download that rules out Test-ExchangeUMCallFlow.
