Explanation:
Box 1: Yes
Traffic from VM1 and VM2 can reach VM3 thanks to the routing table, and as IP forwarding is enabled on VM3, traffic from VM3 can reach VM1.
Box 2: No
VM3, which has IP forwarding, must be turned on, in order for traffic from VM2 to reach VM1.
Box 3: Yes
The traffic from VM1 will reach VM3, which thanks to IP forwarding, will send the traffic to VM2.

Explanation
Scenario: Licensing Issue
1. You attempt to assign a license in Azure to several users and receive the following error message: "Licenses not assigned. License agreement failed for one user."
2. You verify that the Azure subscription has the available licenses.
Solution:
License cannot be assigned to a user without a usage location specified.
Some Microsoft services aren't available in all locations because of local laws and regulations. Before you can assign a license to a user, you must specify the Usage location property for the user. You can specify the location under the User > Profile > Settings section in the Azure portal.
