Suggested answer: C

Explanation:

The alert indicates a potential issue with the VPC/Subnet settings, preventing the cluster nodes from contacting Nutanix services.

To resolve this, the administrator needs to ensure that the subnet 10.0.1.0/24, which is assigned for Bare metal hosts, has an outbound Internet connection.

This connection is necessary for the cluster nodes to communicate with external Nutanix services for updates, license validation, and other essential operations.

Verify that there are appropriate route tables and security group rules allowing outbound traffic to the Internet from the 10.0.1.0/24 subnet.

Ensure that there is either an Internet Gateway (IGW) attached to the VPC or a NAT Gateway configured if using private subnets.

Reference: Refer to the Nutanix documentation and AWS VPC configuration guides to ensure proper Internet connectivity and routing setups.
