QUESTION: 16 Exam Topic: Troubleshoot Microsoft Teams voice issues questions

A company uses a Session Border Controller (SBC) with Teams Direct Routing.
A user reports that they cannot initiate outbound calls to the following number: +41 44 123 45 67.

The user can receive incoming calls. You observe that the user is assigned an OnlineVoiceRoutingPolicy that uses the following number pattern: ^\+41[0-9]{10})$.

You need to resolve the issue.
Which pattern should you use?

.*
^\+30[0-9]{10})$
^\+1[0-9]{10})$
^\+41[0-9]{8})$

Answer(s): A

Explanation:

In some cases, there is a need to route all calls to the same SBC; use -NumberPattern ".*"

Example: Set-CsOnlineVoiceRoute -id "Redmond 1" -NumberPattern ".*" -OnlinePstnGatewayList sbc1.contoso.biz

Incorrect:
Not B: only numbers starting with 30
Not C: only numbers starting with 1

QUESTION: 17 Exam Topic: Troubleshoot Microsoft Teams voice issues questions

You support a Microsoft Teams environment for a company. When users connect to teams outside of the company network, traffic is routed through a VPN.

Users report that chats between internal and external users work well. Users report issues with audio and video quality.

You need to mitigate the issue.
What are two possible ways to achieve this goal? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

Configure packet prioritization by using Quality of Service (QoS)
Implement split-tunneling
Change to a certified VPN provider
Stop using the VPN as the access option

Answer(s): A,B

Explanation:

A: Quality of Service (QoS) QoS is a proven tool to help prioritize packets on a congested network to ensure they arrive at their destination intact and on time. Consider implementing QoS across your organization to maximize the quality of the user experience where bandwidth is constrained. QoS will help solve issues typically associated with high levels of packet loss, and—to a lesser degree—jitter and round-trip times.

B: Split tunneling is a VPN feature that divides your internet traffic and sends some of it through an encrypted virtual private network (VPN) tunnel, but routes the rest through a separate tunnel on the open network. Typically, split tunneling will let you choose which apps to secure and which can connect normally.

This is a useful feature when you need to keep some of your traffic private, while still maintaining access to local network devices. So you can access foreign networks and local networks at the same time. It's also great if you want to save some bandwidth.
