Report
Export

An administrator is tasked with deploying a VM in an NC2 cluster on AWS that needs to by accessed by resources within the on-premises datacenter.

The cluster has the following characteristics:

* 8 nodes

* Resides in the us-east-1a Availability Zone

* Contains 13 Subnets

* Has access to a Direct Connect connection

* Subnet that the User VM (UVM) is being deployed to:UserVM_subnet

There are multiple VMs within the cluster and the UserVM_subnet has access to the on-premises resources.

The administrator deploys the machine, but communication is not possible.

What is the most likely resolution for this situation?

A.
The AWS User Management Security Group requires the new application's ports adding to and traffic

Answers

D.
The AWS IGW requires the new application's ports adding to inbound traffic.
Answers
D.
The AWS IGW requires the new application's ports adding to inbound traffic.
Suggested answer: C

Explanation:

For a VM deployed in an NC2 cluster on AWS to be accessed by resources within the on-premises datacenter, the security group associated with the User VM (UVM) subnet must allow inbound traffic on the specific ports required by the application.

If the security group rules do not permit inbound traffic on these ports, the communication will fail, even if other network configurations are correct.

The administrator should ensure that the UVM Security Group includes rules to allow inbound traffic for the application's required ports, facilitating proper communication between the VM and on-premises resources.

Reference: Refer to the AWS documentation on security group configurations and Nutanix NC2 documentation for details on configuring network access and security group rules.
