HPE2-N68 Online Practice Questions and Answers

You want to connect a Kubernetes pod to a Persistent Volume (PV). What step must you complete before creating the pod?

A. Create a Volume to link to the PV.

B. Create a Persistent Volume Claim (PVC).

C. Create a PV definition on a backend storage array.

D. Enable persistency in the Kubernetes namespace.

A company wants to use Ezmeral Data Fabric to provide storage to Kubernetes Tenants on HPE Ezmeral Container Platform. What deployment option should you choose?

A. Enable the embedded Data Fabric during the controller install. Create hybrid Kubernetes clusters that use Data Fabric and non-Data Fabric nodes.

B. Enable the embedded Data Fabric during the controller install. Also create a dedicated Data Fabric Kubernetes cluster.

C. Disable the embedded Data Fabric during the controller install. Create a dedicated Data Fabric Kubernetes cluster.

D. Disable the embedded Data Fabric during the controller install. Create hybrid Kubernetes clusters that use Data Fabric and non-Data Fabric nodes.

Refer to the exhibits.

You want the HPE Ezmeral Container Platform gateway to provide external access to the service shown in the exhibit. The service is deployed in the Kubernetes Tenant tor which the exhibit shows the settings. However, it is not currently doing so.

What correction must you make to achieve this goal?

A. Reapply the service object with the "Port type" changed to "ClusterlP" and a valid cluster IP specified.

B. Check which ports are available on the gateway. Specify one of those ports as the "nodePort" in the service and reapply it.

C. Select the "Enable Istio Service Mesh" option In the Kubernetes Tenant options; then reapply the service object.

D. Reapply the service object with the "hpecp.hpe.com/hpecp-internal-gateway" label set to "true" in the metadata.

For which use case should you enable Istlo on a Kubernetes cluster?

A. Preparing complex, stateful applications for deployment on Kubernetes

B. Ensuring that the cluster is capable of supporting AI/ML workloads and the full AI/ML lifecycle

C. establishing secure communications between components in a microservtce-based application

D. deploying Spark. MapReduce. and other big data applications that need data management services

A company IT department has strict requirements around data protection and wants you to explain how to use the Max Target and Mm Target options for an HPE Ezmeral Data Fabric volume.

What should you explain?

The Max Target sets the desired RAID level for data In the primary volume. The Mm Target sets the desired RAID level for data In associated mirror and snapshot volumes.

A. The Max Target sets the desired number of replicas for data; the Min Target sets a replica number at which the fabric still tries to reach the Max Target, but less aggressively.

B. The Max Target and Min Target work together to set the erasure coding level for data in the volume. C. The Max Target is the total number of blocks and the Min Target is the total minus redundant blocks.

C. The Max Target sets the desired number of replicas for "hot" (frequently used) data; the Min Target sets the desired number of replicas for "warm" (less frequently used) data.

What Is one way that KubeDirector differs from typical Kubernetes Operators?

A. KubeDlrector embeds a ticket-based authentication system to enhance security for communications across stateful sets.

B. KubeDlrector uses the same deployment objects with which IT is probably already familiar, but makes it easier for IT to catalog and mange the objects.

C. KubeDlrector has a flexible framework that can work for many stateful apps, and Is easier for non-Kubernetes experts to use.

D. KubeDirector is optimized for establishing secure service meshes across cloud-scale, stateless, micro-service-based architectures.

You want to set up high availability (HA) for the HPE Ezmeral Container Platform control plane. This includes HA for gateways and HA for the platform. You are not planning to use the embedded Ezmeral Data Fabric.

Which hosts will you require at minimum?

A. Two hosts with 500 GB for ephemeral storage and 500 GB for OS storage Two hosts with 500 GB for OS storage

B. Three hosts with 500 GB for ephemeral storage and 500 GB for OS storage Two hosts with 500 GB for OS storage

C. Three hosts with 500 GB for OS storage Two hosts with 500 GB for OS storage and 500 GB for ephemeral storage

D. Four hosts with 500 GB for OS storage and 500 GB storage for ephemeral storage

A Tenant Member plans to use KubeDirettor to deploy a Spark 2.4.5 cluster. You need to give cluster members access to data stored in a volume In Ezmeral Data Fabric. What are two required steps?

A. A Tenant Admin must add another role to the Spark 2.4.5 application for the dtap sidecar.

B. The Tenant Member must specify the "hpecp.hpe.com/dtap: hadoop2" pod label under each role when running the cluster.

C. The Tenant Member must create an FS mount to the volume's mount path.

D. A Tenant Admin must create a DataTap to the volume's mount path.

E. The Tenant Member must reference the Data Fabric namespace when running the cluster.

What Is a correct consideration for creating a Kubernetes Tenant on Ezmeral Container Platform?

A. When you select that the Tenant owns the Kubernetes namespace, Tenant Admins are given elevated access to the Kubernetes cluster.

B. When you set a quota for a resource, containers running on the Tenant are not allowed to request or use resources beyond that level.

C. You must manually create a namespace for the Tenant on the Kubernetes cluster before you create the Tenant.

D. When you set a quota for a resource, containers running on the Tenant are guaranteed up to that level.

You want to create a custom dashboard with monitoring information collected by HPE Ezmerat Container Platform. What step should you complete first?

A. Exec Into the epic-monitoring pod on the controller and enable Kibana.

B. Exec into the epic-nagios pod on the controller and start the Nagios service.

C. Access each host managed by the platform and export logs in the "var/log/bluedata" directory.

D. Create a user account and assign that account the "monitoring" role.
