Nutanix Certified Professional – Multicloud Automation (NCP-MCA) — Question 44

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?

Answer options

• 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.

Correct answer: D

Explanation

The correct answer, D, is appropriate because it allows for the creation of a Calm blueprint on Nutanix while manually setting up AWS EC2 instances to ensure redundancy across both environments. Options A, B, and C do not provide the necessary manual setup of AWS instances and rely solely on blueprints, which may not achieve the required redundancy for both cloud and local outages.
