Deployments will fail is lab instructions are not followed correctly. For example, in the screenshot below you can see a deployment has failed due to a policy restriction. Policies are set in place to stop resources from being created that are not required for the lab. Attempting to create 512gb Virtual Machine when actually, you only need a 2gb Virtual Machine will fail. This is by design and is not an error but a warning to state go check the deployment to ensure the lab steps have been carried out correctly.
