Use the drop-down menus to select the answer choice that answers each question based on the information presented in the graphic.

NOTE: Each correct selection is worth one point.

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Box 1: SBC is not sending SIP options.
We see:
Location isn't set.
Status: We can't find any data.
SIP Option status: Warning
TLS connectivity status: Inactive
Network effectiveness (Calls) 100% (3)
Average call duration (Calls) 0 seconds (0)

SIP options issues
After the TLS connection is successfully established, and the SBC is able to send and receive messages to and from the Teams SIP proxy, there might still be problems that affect the format or content of SIP options.

Note: SIP option status
Shows if there is an issue with SIP option flow. Also provides a detailed description of the errors
Values for SIP options status messages are as follows:
* Active – Means SBC is active and the Direct Routing interface sees the options being delivered on a regular interval
--> * Warning, no SIP options – This means that the SBC is discoverable in the environment and is configured to send SIP options, but the Direct Routing service is not receiving SIP options coming back from the SBC
* Warning – SIP Messages aren’t configured – This means that the trunk monitoring for the SIP options is not enabled.
Microsoft Calling System uses SIP options + TLS handshake monitoring to detect the health of the SBC at an application level
If the trunk can be reached when pinging it, but the SBC certificate has expired or SIP stack doesn’t work properly, then Microsoft recommends enabling sending SIP options.

Incorrect:
* SIP Signaling port
Port 5061 is correct.

* There is a problem with the issued certificate

TLS connection issues
If the TLS connection is closed right away and SIP options are not received from the SBC, or if 200 OK is not received from the SBC, then the problem might be with the TLS version. The TLS version configured on the SBC should be 1.2 or higher.

Box 2: Microsoft is sending a 200 OK back to the SBC
SIP options issues
After the TLS connection is successfully established, and the SBC is able to send and receive messages to and from the Teams SIP proxy, there might still be problems that affect the format or content of SIP options.

* SBC receives "200 OK" response but not SIP options
The SBC receives the 200 OK response from the SIP proxy but not the SIP options that were sent from the SIP proxy.

Incorrect:
* Inbound and outbound calls are working with the current configuration.

Contoso uses Microsoft Teams.
Call queue agents report that they are receiving calls from the call queue when they are already on a call.

You need to resolve the issue.
Which two actions should you perform? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

  1. Enable presence-based routing.
  2. Change the call queue’s routing method to Round Robin.
  3. Change the call queue’s routing method to Longest Idle.
  4. Enable Busy on Busy.

Answer(s): A,D

Explanation:

* There is now an option to enable 'presence based routing', previously it was defined by which routing method had been chosen.

Presence-based routing uses the availability status of call agents to determine whether an agent should be included in the call routing list for the selected routing method. Call agents whose availability status is set to Available are included in the call routing list and can receive calls. Agents whose availability status is set to any other status are excluded from the call routing list and won't receive calls until their availability status changes back to Available.

* Busy on busy when in a call (also called "busy options") lets you configure how incoming calls are handled when a user is already in a call or conference or has a call placed on hold. New or incoming calls can be rejected with a busy signal or can be routed accordingly to the user's unanswered settings.

Good news and bad news. Good news is the questions are valid. Bad news is that you need to buy the full PDF version. But with 50% discount when you buy 2 or more exams is not bad.
