AZ-104 Certification Practice Question #163

Question

You deploy an Azure Kubernetes Service (AKS) cluster named Cluster1 that uses the IP addresses shown in the following table.

You need to provide internet users with access to the applications that run in Cluster1.
Which IP address should you include in the DNS record for Cluster1?

Accepted Answer

To provide public internet users with access to applications hosted inside an Azure Kubernetes Service (AKS) cluster, the DNS record must point to a routable public IP address. Among the IP addresses listed in the table, `131.107.2.1` is the only public IP address (acting as the Load Balancer Frontend IP). The other options (`10.0.10.11`, `172.17.7.1`, and `192.168.10.2`) are RFC 1918 private IP addresses used internally by the Kubernetes service, pods, and nodes, making them inaccessible from the public internet.
