The video tutorial covers the networking aspects of microservices in a Kubernetes environment, focusing on how different components communicate. It explains the role of services, Azure virtual networks, ingress controllers, and network policies in managing application connectivity. The tutorial also discusses the importance of load balancers and DNS configurations for efficient traffic routing and application access. Key concepts include internal IPs, node ports, and the use of load balancers to distribute traffic across cluster nodes.

What is the primary role of networking in a container-based microservices approach?

• To isolate application components

• To enable communication between application components

• To reduce the size of application components

• To enhance the security of application components

In Kubernetes, what is the purpose of a service?

• To monitor the performance of application components

• To group pods for direct access via an IP address or DNS name

• To manage the storage of application data

• To provide security for application components

Which component helps in routing complex application traffic in Kubernetes?

• Ingress controllers

• Cluster IP

• Kube-proxy

• Network policies

What is the function of a node port in Kubernetes?

• To balance the load between different nodes

• To map a port on the node for direct application access

• To secure the network traffic for the pods

• To provide a static IP address for external access

How does an external load balancer differ from an internal load balancer in Kubernetes?

• An external load balancer can have a public IP address, while an internal one only has a private IP address

• An external load balancer is used for storage, while an internal one is used for networking

• An external load balancer is used for security, while an internal one is used for performance

• An external load balancer uses a static IP address, while an internal one uses a dynamic IP address
