Hot Area:
Answer : 
Box 1: New-CsTenantNetworkSite -
Define network sites.
Use the New-CsTenantNetworkSite cmdlet to define network sites. Each network site must be associated with a network region.
New-CsTenantNetworkSite -NetworkSiteID <site ID> -NetworkRegionID <region ID>
Box 2: New-CsTenantNetworkSubnet
Define network subnets -
Use the New-CsTenantNetworkSubnet cmdlet to define network subnets and associate them to network sites. Each network subnet can only be associated with one site.
New-CsTenantNetworkSubnet -SubnetID <Subnet IP address> -MaskBits <Subnet bitmas
Box 3: -SubnetID -

Question 3
You are piloting Microsoft Teams in a network environment.
You need to test the environment to ensure that VPN users are configured correctly for split tunneling.
What should you use?
- A. Microsoft 365 network connectivity test tool
- B. Microsoft Remote Connectivity Analyzer
- C. Network planner
- D. Teams Network Assessment Tool
Answer : A
Microsoft 365 Network Connectivity Test Results includes a VPN Split Tunnel section:
Each Optimize category route for Exchange Online, SharePoint Online, and Microsoft Teams is tested to see if It's tunneled on the VPN. A split out workload avoids the VPN entirely. A tunneled workload is sent over the VPN. A selective tunneled workload has some routes sent over the VPN and some split out. A passing result will show if all workloads are split out or selective tunneled.

Question 4
You create a network region Region1 in Microsoft Teams.
You are adding a network site to Region1. The site has a 1.5-Mb connection.
You need to ensure that all users at the site have a good voice experience.
What should you do?
- A. Create and assign a Teams Network Roaming Policy that has IP video disabled.
- B. Assign the Region1 users a meeting policy that has a media bit rate of 1,500 Kbs.
- C. Run the Microsoft 365 network connectivity test tool.
- D. Create and assign a Teams Network Roaming Policy that has a media bit rate of 500 Kbs.
Answer : D
Find your minimum internet connection speed.
When you select Generate report, Microsoft 365 creates a report.
Under the Impact column and in the Office 365 row, this number shows how much of your internet connection Teams and Phone System will use. We recommend that this number is no more than 30 percent of your total internet connection speed. For example, if your internet connection is 60 Mbps, Teams and Phone
System should use no more than 18 Mbps.
New-CsTeamsNetworkRoamingPolicy allows IT Admins to create policies for Network Roaming and Bandwidth Control experiences in Microsoft Teams.
The -MediaBitRateKb parameter determines the media bit rate for audio/video/app sharing transmissions in meetings.

Question 5
You are adding new sites to your company.
The reporting team needs location-based reports in Microsoft Power BI that include the subnet information of the new sites.
You need to add the information to Microsoft Teams.
What should you do?
- A. From the Microsoft Teams admin center, add the subnets to the Network planner.
- B. From the Microsoft Call Quality Dashboard, upload tenant data.
- C. From the Microsoft Teams admin center, define a network topology.
- D. From the Microsoft Teams admin center, define a network subnet.
Answer : C
Manage your network topology for cloud voice features in Microsoft Teams.
You configure network settings on the Network topology page of the Microsoft Teams admin center or by using Windows PowerShell.
Note: If your organization is deploying Location-Based Routing for Direct Routing or dynamic emergency calling, you must configure network settings for use with these cloud voice features in Microsoft Teams. Network settings are used to determine the location of a Teams client and include network regions, network sites, subnets, and trusted IP addresses. Depending on the cloud voice feature and capability that you're deploying, you configure some or all these settings.

Question 6
HOTSPOT -
Your company is migrating from a legacy PBX system to Microsoft Teams.
The phone number range is + 1-423-555-1xxx. The PBX system uses four-digit dialing internally. Extensions are the last four digits of the number.
You need to ensure that you can use four-digit dialing for your numbers in Teams. The solution must minimize administrative effort.
How should you configure the normalization rule? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Answer : 
Box 1: +14235551\d{3}
Need to string away + 1-423-555-1, and keep only 3 digits.
Example:
New-CsTeamsTranslationRule -Identity 'AddPlus1' -Pattern '^(\d{10})$' -Translation '+1$1'
This example creates a rule that strips +1 from any E.164 eleven digits number. For example, +12065555555 will be translated to 206555555
Example 2:
New-CsTeamsTranslationRule -Identity 'StripE164SeattleAreaCode' -Pattern '^\+1206555(\d{4})$' -Translation '$1'
This example creates a rule that strips +1206555 from any E.164 ten digits number. For example, +12065555555 will be translated to 5555
Box 2: +1423555$1 -
Keep the 3 digits. Add one digit with the translation.
