What is the minimum number of each license you should purchase? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation:
Box 1: 0
Teams Premium
For 45 Teams Rooms devices, you will need 45 Teams Rooms and Teams Rooms Pro licenses, not Teams Premium licenses.
Box 2: 20
Teams Rooms Pro
For 45 Microsoft Teams Rooms devices, you will need 20 Teams Rooms Pro licenses, as the Basic license only supports up to 25 devices. Teams Premium is a different license that adds advanced features to meetings, and is not related to licensing the devices themselves.
Box 3: 25
Teams Rooms Basic
You can assign up to 25 Microsoft Teams Rooms Basic licenses to Teams Rooms systems in your organization. If you need to license more than 25 Teams Rooms systems, those additional licenses need to be Teams Rooms Pro licenses. Teams Rooms Basic licenses can be used to license Teams Rooms systems only and not Teams Panels.

Hotspot Question
Which Teams Phone feature supports the planned changes for the IT department, and which type of license is required? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation:
Box 1: Channel based call queue
A channel-based call queue can be configured with a Direct Inward Dialing (DID) number that can be used for both inbound and outbound calls. This allows callers to reach the queue directly via the DID number, and agents can also use the same DID number when making outbound calls.
Box 2: Teams Phone Standard
For a Teams channel-based call queue with a DID number used for both inbound and outbound calls, you'll need a Microsoft Teams Phone Resource Account license for the resource account associated with the call queue, along with PSTN connectivity (like Microsoft Calling Plan, Operator Connect, or Direct Routing). Additionally, users interacting with the call queue need Microsoft Teams Phone Standard licenses or equivalent.
