D.Decrease the resource capacity of the VMs
E.Generate a new registration key for the VM

Correct Answers: A and C 
Error: “Connection not found: RDAgent does not have an active connection to the broker” indicates that your virtual machines may be at their connection limit, so the VMs can`t accept new connections. This issue can be resolved by decreasing the max session limit and increasing the resource capacity of the virtual machines.
Option A is correct. Decreasing the max session limit will ensure that the resources are more evenly distributed across session hosts and it will prevent resource depletion.
Option B is incorrect. To resolve the given issue, it is recommended to decrease the max session limit.
Option C is correct. Increasing the resource capacity of virtual machines will increase the connection limit for the VMs.
Option D is incorrect. resource capacity of VMs needs to be increased, not decreased.
Option E is incorrect. Generating the new registration key is not the recommended solution to resolve the issue.
