Quiz: Red Hat OpenShift Container Platform Architecture

Red Hat OpenShift Container Platform Architecture

Choose the correct answers to the following questions:


  1. 1.

    Which statement is correct about how Red Hat OpenShift extends Kubernetes?

    A

    Red Hat OpenShift adds features to make application development and deployment easy and efficient.

    B

    The containers that run on Red Hat OpenShift do not support Kubernetes.

    C

    To enable new features, Red Hat maintains forked versions of Kubernetes.

    D

    There are no new features for continuous integration and continuous deployment in Red Hat OpenShift, but you can use external tools instead.

  2. 2.

    How do Kubernetes components communicate to orchestrate containers?

    A

    The container runtime is the central orchestration component that communicates directly to the containers.

    B

    Kubelet communicates orchestration decisions to the control plane, which is responsible for running containers.

    C

    The control plane communicates orchestration decisions to the cluster nodes through Kubelet, which runs on each node.

    D

    Etcd communicates with Kubelet to run containers in cooperation.

  3. 3.

    Which two statements are correct regarding the control plane? (Choose two.)

    A

    Red Hat OpenShift can operate without a control plane. The nodes form a peer-to-peer network.

    B

    The control plane of Red Hat OpenShift manages the lifecycle of containers and controls the cluster.

    C

    The control plane nodes of Red Hat OpenShift run on Red Hat Enterprise Linux CoreOS.

    D

    The control plane nodes of plain Kubernetes must run on Red Hat Enterprise Linux CoreOS.

    E

    The control plane nodes of Red Hat OpenShift run on Red Hat Enterprise Linux.

  4. 4.

    Red Hat OpenShift adds additional functionality to extend Kubernetes. Which one of the following options is an OpenShift-specific component?

    A

    etcd

    B

    Kubelet

    C

    Control plane

    D

    Image registry

  5. 5.

    Which two statements are correct regarding the Kubernetes state? (Choose two.)

    A

    Kubernetes continuously verifies the state of the system and performs the necessary actions to reach the desired state.

    B

    To define the desired state, you must interact with the Kubernetes controllers.

    C

    To define the desired state, you must interact with the Kubernetes API.

    D

    Kubernetes continuously verifies the state of the system by defining custom resources.
