NEW QUESTION # 21
Your e-commerce application is deployed on a public cloud. As compared to the rest of the year, it receives substantial traffic during the Christmas season.
In this scenario, which cloud computing feature automatically increases or decreases the resources based on the demand?

• A. on-demand self-service
• B. rapid elasticity
• C. resource pooling
• D. broad network access

Answer: B

Explanation:
Explanation
The cloud computing feature that automatically increases or decreases the resources based on the demand is known as rapid elasticity1112. In cloud computing, scaling is the process of adding or removing compute, storage, and network services to meet the demands a workload makes for resources in order to maintain availability and performance as utilization increases11.

NEW QUESTION # 22
Which statement is correct about overlay or underlay networks or fabrics?

• A. Overlay networks are Layer 3 networks that must use OSPF for routing purposes.
• B. Underlay fabrics decouple network services from the overlay infrastructure.
• C. Underlay fabrics enable multitenancy through virtualization.
• D. Overlay networks are virtual networks.

Answer: D

Explanation:
Explanation
Overlay networks are indeed virtual networks. They are logical constructs that stitch together disparate, dispersed network infrastructure, often referred to as underlay1. Underlay networks refer to the physical network infrastructure, while overlay networks implement network virtualization concepts2.

NEW QUESTION # 24
In the CN2 architecture, which component integrates with the orchestrator to listen for changes and take action on any events affecting network resources?

• A. cni.bin
• B. contrail-vrouter-agent
• C. contrail-k8s-kubemanaqer
• D. kube-a pi server

Answer: C

Explanation:
Explanation
contrail-k8s-kubemanager is the component in the CN2 architecture that integrates with the orchestrator (such as Kubernetes or OpenShift) to listen for changes and take action on any events affecting network resources. According to the CN2 components documentation2, contrail-k8s-kubemanager is "the interface between Kubernetes resources and Contrail resources" that "watches the kube-apiserver for changes to regular Kubernetes resources such as service and namespace and acts on any changes that affect the networking resources". Other components in the CN2 architecture are contrail-k8s-apiserver2, which is an aggregated API server that manages all Contrail resources; cni.bin, which is a binary file that implements the Container Network Interface (CNI) specification for CN2; and contrail-vrouter-agent, which is a pod that runs on every node and communicates with the CN2 control plane to program the data plane.

The LoadBalancer service type in Kubernetes exposes the service externally using a cloud provider's load balancer67. NodePort and ClusterIP services, to which the external load balancer routes, are automatically created

NEW QUESTION # 27
You want to limit the memory, CPU, and network utilization of a set of processes running on a Linux host.
Which Linux feature would you configure in this scenario?

• A. control groups
• B. virtual routing and forwarding instances
• C. network namespaces
• D. slicing

Answer: A

Explanation:
Explanation
Control groups (cgroups) is a Linux kernel feature that limits, accounts for, and isolates the CPU, memory, disk I/O, and network usage of one or more processes678. It allows you to allocate resources among user-defined groups of processes running on a system. You can monitor the groups of processes, deny the groups of processes access to certain resources, or even freeze groups of processes

NEW QUESTION # 28
Which two statements are correct about containers? (Choose two.)

• A. Containers reduce deployment efficiency.
• B. Containers require an underlying operating system.
• C. Containers have faster boot times than VMs. www*
• D. Containers include the entire operating system.

Answer: B,C

Explanation:
Explanation
Containers are lightweight because they don't need the extra load of a hypervisor, but run directly within the host machine's kernel1. This means they start up almost instantly and use less RAM. Images are constructed from layered filesystems and share common files, making disk usage and image downloads much more efficient1. Containers are isolated from each other and the host system. They have their own filesystem and networking, and can be constrained to not allow root access outside the container1. They run on top of a host operating system1.

NEW QUESTION # 29
What is the networking service of OpenStack?

• A. Neutron
• B. ironic
• C. Barbican
• D. Heat

Answer: A

Explanation:
Explanation
OpenStack's networking service is known as Neutron. Neutron provides a scalable, API-driven, web services-based model for network connectivity as a service. It is designed to manage and configure networking services for both simple and complex network topologies. Neutron allows users to create their own networks, control traffic and connect servers and devices to one or multiple networks.

• A. cri-o
• B. Docker
• C. runC
• D. containerd

Answer: A

The default container runtime engine used by OpenShift is cri-o. CRI-O is an open source, community-driven container engine. Its primary goal is to replace the Docker service as the container engine for Kubernetes implementations, such as OpenShift Container Platform3.

NEW QUESTION # 32
What is an OpenShift route?

• A. It allows pods to communicate across clusters.
• B. It allows pods to communicate across namespaces.
• C. It provisions endpoints for a service.
• D. It provisions external access to a service.

Answer: D

Explanation:
Explanation
An OpenShift route is a way to provision external access to a service. A route exposes a service at a host name, such as www.example.com, that external clients can use to access the service. A route can also specify security options, such as TLS termination, and load balancing options, such as round robin or least connection

NEW QUESTION # 33
Click the Exhibit button.

You apply the manifest file shown in the exhibit.
Which two statements are correct in this scenario? (Choose two.)

• A. This manifest is used to create a
• B. The created pods are receiving traffic on port 80.
• C. Four pods are created as a result of applying this manifest.
• D. This manifest is used to create a deployment.

Answer: C,D

Explanation:
Explanation
This manifest is used to create a deployment, which is a Kubernetes resource that manages a set of pods with the same configuration. A deployment can also provide declarative updates, scaling, and rolling back for the pods. The created pods are not receiving traffic on port 80, because the manifest does not specify a service or a selector for the deployment. A service is another Kubernetes resource that defines a logical set of pods and a policy to access them. A selector is a label query that matches the pods that belong to the service. Four pods are created as a result of applying this manifest, because the manifest specifies replicas: 4 in the spec section of the deployment
