[&] You are deploying a web app to an Azure Kubernetes Service. You need to deploy 3 instances of the web app and automatically load balance between them.  What do you do?
- Create a Kubernetes control file that deploys three pods running the web app.  Configure load balancer rules on the included Azure load balancer to distribute requests to port 80 and 443 to the pods.
- Create a Kubernetes control file that deploys three instances of the application.  Set the appropriate ports for the deployment in the control file.  Add a service that maps to the deployment.
- Create a Kubernetes control file that deploys three pods running the web app.  Configure load balancer rules on the included Azure load balancer to distribute requests to port 80 and 443 to the pods.  Create NSG rules to allow traffic from the internet on ports 80 and 443.
- Ensure that there are three nodes in the Kubernetes cluster.  Add load balancer rules to the included Azure load balancer that distribute requests to port 80 and 443 to the agent nodes.  Create a Kubernetes control file that provisions a pod running the application on each node.
