In this diagram, the primary key store of Kubernetes in the control plane.
What is etcd?
100
The default type of deployment strategy in Kubernetes
What is a rolling update?
100
Depicted below, this is a common type of controller available in Kubernetes.
What is a cron job?
100
A set of virtual machines with the same configuration in AKS
What is a node pool?
100
This service can be used to route traffic internally within a cluster to multiple pods.
What is a cluster IP?
200
In this diagram, a CLI that is commonly connected to the API.
What is kubectl?
200
Used in deployments, these data filter based on labels when specified
What are selectors?
200
These containers are sometimes placed within pods and need to "finish" before the main container is in a running state.
What are init containers?
200
In AKS, this service automatically right sizes your node pool depending on the work to be scheduled.
What is the cluster autoscaler?
200
This service allows external traffic to reach a cluster, even if the pods have no external IP addresses.
What is a load balancer?
300
The smallest unit of compute in Kubernetes
What is a pod?
300
The CLI kubectl has two commands, apply and create. While create is specific in how it expects Kubernetes to deploy, apply uses a ____________ syntax which is preferred.
What is declarative?
300
This type of probe tells Kubernetes to restart a container in a pod after it has started but is no longer responsive.
What is a liveness probe?
300
The default AKS networking model, shown below, is notable because none of the pods can be accessed outside of the cluster, but can be a good option when you lack IP addresses. 
What is Kubenet?
300
These allow combinations of non-confidential environment variables to be injected into containers.
What are config maps?
400
These are not created directly, but form a record of deployments send to the control plane in Kubernetes
What are replica sets?
400
These types of volumes no longer exist when a pod is destroyed.
What are ephemeral?
400
This type of probe prevents Kubernetes from routing requests to a pod via a service if it fails - instead, Kubernetes will try to route to a different pod.
What is a readiness probe?
400
This service integrates AKS with Azure Monitor.
What is Container Insights?
400
Unlike Kubernetes secrets, these are actually encrypted instead of encoded.
What are sealed secrets?
500
Depicted below, the components that run workloads.
What are worker nodes?
500
Depicted below, the following example of a pod is a common way multiple containers are used within a single pod using a _____ pattern. 
What is a sidecar?
500
This type of controller is what we presently use on our own Kubernetes cluster, depicted below.
What is an ingress controller?
500
This is the current network plugin used with our AKS cluster. It allows direct access to the pods outside the cluster.
What is Azure CNI?
500
This file, pictured below, can define many things, one of which is the API endpoint for kubectl.
What is KubeConfig?
