description: Containers are isolated units of software that run on a shared operating system (OS) kernel. A container packages an application with its dependencies and abstracts it from the host OS where it runs.

- content: "Which types of virtual switches are used in container networking?"
19
-
choices:
20
-
- content: "Standard, Hybrid"
21
-
isCorrect: false
22
-
explanation: "Incorrect. The terms standard and hybrid are used to describe an Azure Kubernetes Service (AKS) implementation with Windows containers, but these options aren't types of virtual switches."
23
-
- content: "NAT, Transparent, Overlay"
24
-
isCorrect: true
25
-
explanation: "Correct. Windows containers on Kubernetes require Azure container network interface (CNI) plugins. The Azure CNI plugin is an overlay virtual switch network solution. Two examples include Flannel Overlay and Project Calico."
26
-
- content: "Public, Private"
27
-
isCorrect: false
28
-
explanation: "Incorrect. You can implement network policies to control public and private access to your Windows containers, but these options aren't types of virtual switches."

30
-
choices:
31
-
- content: "Virtual machine, Virtual switch"
32
-
isCorrect: false
33
-
explanation: "Incorrect. In a networking configuration, Windows containers function like virtual machines, where each container has a virtual network adapter connected to a virtual switch. These items aren't types of network isolation."
34
-
- content: "Kernel mode, User mode"
35
-
isCorrect: false
36

37
-
- content: "Process, Hyper-V"
38
-
isCorrect: true
39
-
explanation: "Correct. Windows containers support Process and Hyper-V network isolation. Under process isolation, containers on the same host support isolation through the namespace, resource control settings, and other process functions. Under Hyper-V isolation, each container runs in an optimized virtual machine that provides hardware-level isolation between the container and the host."

-
explanation: "Incorrect. In a Kubernetes networking configuration, Kubernetes nodes (physical or virtual machines) are managed by a control plane. The control plane communicates with the nodes through the kubelet component."
