Module assessment

1.

Your development team added a new feature to the shopping basket component of the online store application. You want to deploy the new feature without incurring any downtime for your application. You use the Kubernetes rolling update feature to deploy the new feature. How does a rolling update affect the IP addresses that are in use by the application?

The IP addresses used by the application's pods and services remain the same.

The IP addresses used by the application's pods change, but the service IP address remains the same.

The IP addresses used by the application's pods and services change.

2.

What do you need to include in your calculation when deciding how many IP addresses your cluster needs?

An IP address for each node in the cluster, which includes spare capacity to handle scaling up, plus an IP address for every pod you run in the cluster.

An IP address for each node in the cluster, which includes spare capacity to handle scaling up and cluster upgrades, plus an IP address for every pod you run in the cluster.

An IP address for each node in the cluster, which includes spare capacity to handle scaling up and cluster upgrades, plus IP addresses equal to the maximum pods value defined for the cluster, which should be multiplied by the number of nodes.

3.

You calculated how many IP addresses your Azure Kubernetes Service (AKS) cluster requires. You now need to calculate the size of your Azure Virtual Network subnet. How many reserved addresses do you need to account for?

None. You just need to know how many IP addresses your application requires.

Two, because you can't use the first and last IP addresses in an Azure Virtual Network subnet because they're reserved.

Five, because in an Azure Virtual Network subnet, you can't use the first and last IP addresses, and three more addresses are reserved for Azure internal use.
