Within a Calm blueprint, which two actions can an administrator apply to a Service under the Guest Customization section? (Choose two.)

An administrator has been tasked with creating a multicloud, three-tier application using Calm. The application needs to consist of:
A MongoDB backend database
A NodeJS Javascript runtime environment
An NGINX webserver
The administrator has access to an AWS account, as well as a locally hosted Nutanix cluster. The three parts of the application should be fully redundant, and be able to tolerate either a cloud provider outage, or a local Nutanix cluster outage.
What is the most appropriate solution the administrator should choose in order to meet the requirements?

Prism Central reporting indicates that there are multiple memory-constrained VMs in multiple clusters. The target VMs have Memory Hot Add enabled.
Using X-Play, in what order should the Playbook actions be added to ensure the VMs are properly remediated?

An administrator wants to be alerted when production VMs become idle. The VMs will be determined to be idle when CPU usage is lower than 5% for more than 5 minutes. All affected VMs are categorized as Environment:Production, since they have Flow microsegmentation rules.
What should the administrator do to satisfy this requirement?

A company wants to ensure that all developers are able to request new development environments on demand by using ServiceNow.
The administrator notices that even though developers create new environments, they rarely remove these environments when moving on to new assignments. Today, the administrator has gone into Prism Central to check when the VM was created, in order to reach out to the developer and ask if it can be deleted. The administrator has accidentally deleted the wrong VM in the past.
Which two methods can the administrator use to automate this task to avoid deleting the incorrect VMs? (Choose two.)
