In this case, you have two alert rules: Alert1 and Alert2. Alert1 has a scope of RG1, which means it applies to all the resources in the resource group named RG1. Alert1 has a condition of All Administrative operations, which means it triggers when any administrative operation is performed on the resources in RG1. An administrative operation is any operation that changes the configuration or state of a resource, such as creating, deleting, updating, or restarting.

Alert2 has a scope of VM1, which means it applies only to the virtual machine named VM1. Alert2 also has a condition of All Administrative operations, which means it triggers when any administrative operation is performed on VM1.

Now, let’s see which alert rules are triggered by each user.

User1 creates a new virtual disk and attaches the disk to VM1. This is an administrative operation on VM1, so it triggers Alert2. However, it does not trigger Alert1, because the new disk is not part of RG1. Therefore, the correct answer for User1 is C. Only Alert2 is triggered.

User2 creates a new resource tag and assigns the tag to RG1 and VM1. This is also an administrative operation on both RG1 and VM1, so it triggers both Alert1 and Alert2. Therefore, the correct answer for User2 is D. Alert1 and Alert2 are triggered.
