Which operating system must be used for control plane machines in Red Hat OpenShift?
- A . Ubuntu
- B . Red Hat Enterprise Linux
- C . Red Hat CoreOS
- D . Centos
C
Explanation:
Red Hat OpenShift requires specific operating systems for its control plane machines to ensure stability, security, and compatibility.
Let’s analyze each option:
The openstack user list command uses which OpenStack service?
- A . Cinder
- B . Keystone
- C . Nova
- D . Neutron
B
Explanation:
OpenStack provides various services to manage cloud infrastructure resources, including user management.
Let’s analyze each option:
Which component of a software-defined networking (SDN) controller defines where data packets are forwarded by a network device?
- A . the operational plane
- B . the forwarding plane
C the management plane - C . the control plane
D
Explanation:
Software-Defined Networking (SDN) separates the control plane from the data (forwarding) plane, enabling centralized control and programmability of network devices.
Let’s analyze each option:
You are asked to deploy a Kubernetes application on your cluster. You want to ensure the application, and all of its required resources, can be deployed using a single package, with all install-related variables defined at start time.
Which tool should you use to accomplish this objective?
- A . A YAML manifest should be used for the application.
- B . A Helm chart should be used for the application.
- C . An Ansible playbook should be run for the application.
- D . Kubernetes imperative CLI should be used to run the application.
B
Explanation:
To deploy a Kubernetes application with all its required resources packaged together, a tool that supports templating and variable management is needed.
Let’s analyze each option:
You want to create a template that defines the CPU, RAM, and disk space properties that a VM will use when instantiated.
In this scenario, which OpenStack object should you create?
- A . role
- B . Image
- C . project
- D . flavor
D
Explanation:
In OpenStack, a flavor defines the compute, memory, and storage properties of a virtual machine (VM) instance.
Let’s analyze each option:
Which two statements are correct about an underlay network? (Choose two.)
- A . An underlay network can be built using either Layer 2 or Layer 3 connectivity.
- B . A Layer 3 underlay network uses routing protocols to provide IP connectivity.
- C . The underlay network is the virtual network used to connect multiple virtual machines (VMs).
- D . The underlay network is built using encapsulations tunnels.
A, B
Explanation:
An underlay network refers to the physical or logical network infrastructure that provides the foundation for overlay networks in cloud environments. It handles the actual transport of data between devices and serves as the backbone for cloud architectures.
Let’s analyze each statement:
Which two statements about containers are true? (Choose two.)
- A . Containers contain executables, libraries, configuration files, and an operating system.
- B . Containers package the entire runtime environment of an application, including its dependencies.
- C . Containers can only run on a system with a Type 2 hypervisor.
- D . Containers share the use of the underlying system’s kernel.
B, D
Explanation:
Containers are a lightweight form of virtualization that enable the deployment of applications in isolated environments.

Let’s analyze each statement:
Which two statements are correct about Kubernetes resources? (Choose two.)
- A . A ClusterIP type service can only be accessed within a Kubernetes cluster.
- B . A daemonSet ensures that a replica of a pod is running on all nodes.
- C . A deploymentConfig is a Kubernetes resource.
- D . NodePort service exposes the service externally by using a cloud provider load balancer.
A, B
Explanation:
Kubernetes resources are the building blocks of Kubernetes clusters, enabling the deployment and management of applications.
Let’s analyze each statement:
Which Docker component builds, runs, and distributes Docker containers?
- A . dockerd
- B . docker registry
- C . docker cli
- D . container
A
Explanation:
Docker is a popular containerization platform that includes several components to manage the lifecycle of containers.
