Explanation:
To restrict Teams bandwidth by network range, you can use the Network Roaming Policy feature1. This feature allows you to define different media bit rate settings for different network locations based on the IP address ranges. Here are the steps to accomplish your task:
* Create a new network roaming policy with the desired media bit rate settings. For example, you can use the following PowerShell cmdlet to create a policy named "MiamiPolicy" with a maximum bit rate of
1000 Kbps for audio and video:
New-CsTeamsNetworkRoamingPolicy -Identity "MiamiPolicy" -MaxMediaBitRateKb 1000
* Assign the network roaming policy to the network range of the Miami office. You can use the following PowerShell cmdlet to assign the policy to the 10.10.10.0/24 network range:
New-CsTeamsNetworkRoamingPolicyAssignment -PolicyName "MiamiPolicy" -IPAddressRange "10.10.10.0
/24"
* Verify that the policy is applied correctly by using the Get-
CsTeamsNetworkRoamingPolicyAssignment cmdlet. You should see something like this:
Identity : 10.10.10.0/24
PolicyName : MiamiPolicy
IPAddressRange : 10.10.10.0/24

Note: You may need to wait for some time for the policy to take effect.

Explanation:
To ensure that all unused teams expire and are deleted automatically, you need to configure a Microsoft 365 group expiration policy. This policy applies to teams because they are backed by groups. Here are the steps to follow:
* Sign in to the Microsoft 365 admin center with your admin credentials.
* Go to Groups > Expiration.
* Turn on the Enable expiration toggle.
* In the Group lifetime box, enter 365 days or select it from the drop-down list. This means that the teams will expire 365 days from their creation date.
* In the Select group types to apply the policy section, check the Teams box. You can also select other group types if you want.
* In the Choose how to handle owners of groups without owners section, enter adminLOD-Se551723.
onmicrosoft.com as the email address to receive notifications for the expiration of orphaned teams.
You can also add more email addresses if you want.
* Click Save to apply the policy.
That's it. You have successfully configured a group expiration policy for teams. This policy will automatically delete the teams that are not renewed by their owners before the expiration date. You can also view and restore the deleted teams within 30 days from the Deleted groups page in the admin center.

Topic 3, A. Datum Corporation
A Datum Corporation is an energy company that has offices across North America and 3,000 employees.
A Datum has the offices shown in the following table.

The office in Calgary has a 1 -Gbps internet circuit. The offices in San Diego and New York have 100-Mbps internet circuits. The field site in Edmonton has a 3-Mbps internet circuit.
A Datum has the following departments:
* Information technology (IT)
* Project management
* Marketing
A Datum recently purchased a Microsoft 365 E5 subscription that has the Microsoft Teams Domestic Calling Plan add-on. All users are assigned Microsoft 365 E5 and Microsoft Teams Domestic Calling Plan licenses and Calling Plans is deployed.

The Teams policies settings are configured as shown in the following exhibit

The Teams client is deployed to a non-persistent Virtual Desktop infrastructure (VDI) used by the project management department.
Allow guest access in Teams is set to Off.
The Microsoft Viva Connections app is deployed to all users.
A Datum identifies the following issues:
* An executive at the San Diego office reports that video drops during Teams meetings.
* The Edmonton field site has limited bandwidth, and users report poor audio during Teams calls and meetings.
* Users in the project management department report that they cannot give or take control during Teams calls and meetings while sharing their VDl desktop.
A Datum plans to implement the following changes:
* Configure the media bit rate settings for the users at the Edmonton field site. The settings must apply only to the users while they are at the site, but NOT when they are at a different office.
* Create a Teams channel to enable the project management department to collaborate with the IT department on a device upgrade project.
* Implement a pilot rollout of Operator Connect for the users in the New York office. A port request was accepted already.
* Create a Teams channel for the marketing department for external collaboration.
