Question 31 - NCP-CI-AWS discussion

Report
Export

An administrator has deployed an NC2 cluster in AWS.

The following configuration decisions were made:

Created a new VPC from the NC2 console as part of the deployment

Selected the Public option for prism access policy

Host type selected was i13en,metal

The administrator now has a goal of provision public internet access to a user VM (UVM),web-1, on the Nutanix cluster. The admin can access Prism Element via the public DNS of the Auto-created load balancer.

The administrator tries to create another network load balancer for the web server access. After creating the load balancer and registering web-1's IP address as a target, the administrator finds that the health check for the VM target is failing and the DNS returns as NOT Found message in the browser.

Why is the issue happening?

A.
The load balancer is still in a Provisioning state.

Answers
C.

D.
The administrator needs to provision an application load balancer instead of a network load balancer to allow Internet traffic to access the UVM subnet.
Answers
D.
The administrator needs to provision an application load balancer instead of a network load balancer to allow Internet traffic to access the UVM subnet.
Suggested answer: C

Explanation:

For a VM to be accessible over the internet through a load balancer, the VM itself must have a public IP address.

In this case, the health check for the VM target is failing and the DNS returns a 'NOT Found' message because web-1 does not have a public IP assigned.

Without a public IP, the load balancer cannot route traffic to web-1 from the internet.

Assigning a public IP to web-1 ensures that the VM can be accessed via the load balancer, resolving the connectivity issue.

Reference: Refer to the AWS documentation on network load balancers and public IP assignments, and Nutanix documentation on VM network configurations.
