What is the most appropriate solution the administrator should choose in order to meet the requirements?

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?
A . Create a Calm blueprint with MongoDB, Node/S, and NGINX VMs running on Nutanix, as well as an NGINX server running in AWS on US-WEST-1 and US-EAST-1.
B . Create a Calm blueprint with MongoDB, Node/S and NGINX VMs running on Nutanix, and a separate blueprint for MongoDB, NodeJS, and NGINX running in AWS on US-WEST-1 and US-EAST-1.
C . Create a Calm blueprint with MongoDB, NodelS, and NGINX VMs running on Nutanix, as well as MongoDB, NodeJS, and NGINX servers running in AWS on US-WEST-1 and US-EAST-1.
D . Create a Calm blueprint with MongoDB, NodelS, and NGINX VMs running on Nutanix, then manually create three EC2 instances for MongoDB, NodeJS and NGINX in AWS running on US-WEST-1 and
US-EAST-1.

Answer: C

Explanation:

This solution meets the requirements of creating a multicloud, three-tier application using Calm. It ensures that each tier of the application has a redundant copy running on both Nutanix and AWS, and that the application can tolerate either a cloud provider outage or a local Nutanix cluster outage. The other options do not provide full redundancy for each tier, or require manual intervention to create the AWS instances.
