According to the Nutanix Calm documentation1, to scale out an existing Calm environment, the administrator needs to back up the data and create three Calm VMs from the Calm VM OVA template. The administrator then needs to configure the Calm VMs as a cluster and restore the data from the backup. The other options are incorrect because they either do not use the correct image format, do not create a cluster of Calm VMs, or destroy the existing Calm VM. References:

According to the Nutanix Multicloud Automation Administration (NMCAA) course, the recommended Prism Central VM size depends on the number of VMs that are managed by Calm and the number of concurrent users. For a large-scale environment with more than 5000 VMs and more than 100 concurrent users, the recommended size is 3 nodes Large - 10vCPU and 52GB Memory per node1. This size provides enough resources for the Prism Central cluster to handle the workload and performance requirements of Calm.

 A macro is a placeholder for a value that is resolved at runtime. Macros can be used to reference various Calm objects, such as variables, secrets, credentials, tasks, and services. The correct syntax for using a macro within a Calm blueprint is @@{calm.object}(@@, where calm.object is the name of the object to be referenced. For example, @@{username}(@@ would resolve to the value of the username variable at runtime. The other options are incorrect syntaxes for macros and would not be resolved by Calm. References: Nutanix Certified Professional - Multicloud Automation (NCP-MCA) v6.5, Nutanix Certified Professional - Multicloud Automation (NCP-MCA) 6 Exam, Nutanix Certified Professional - Multicloud Automation

An HTTP task is a type of task that can be added to a blueprint or a runbook to perform REST API calls to external systems. An HTTP task can be used to reserve an IP address in the IPAM system before deploying a VM or an application, by sending a POST request with the required parameters and headers. The HTTP task can also capture the response from the IPAM system and store it as a variable for later use. This is the simplest and most efficient way to integrate with an IPAM system, as it does not require any additional configuration or scripting.
