Questions # 1:

A customer needs an Ezmeral Container Platform solution for supporting a mix of statef ul and stateless applications. The customer also wants the platform to nost Ezmeral Data Fabric on Kubernetes.

Which systems are recommended for the Data Fabric workers?

Options:

SimpliVity 380s

Synergy 380s

Apollo 4200s

Apollo 6500s

Answer

Questions # 2:

What Is the arbiter's role in the HPE Ezmeral Container Platform?

Options:

Direct the shadow controller to begin managing the platform if the controller fails

Monitor the gateway and notify the administrator if a critical error occurs

Detect if the controller or shadow controller has failed and begin managing the platform

Load balance requests sent to the controller and shadow controller

Answer

Questions # 3:

What is one benefit that HPE Ezmeral Container Platform provides for loT deployments?

Options:

It supports Edgeline servers, which are specialized for the edge, as hosts within the platform.

It provides APIs for deploying the platform services on mobile devices.

Its control plane runs in the HPE cloud, which brings the scalability required for lot

It supports importing third-party loT platforms as clusters managed by the platform.

Answer

Questions # 4:

You have created a Data Fabric-type Kubernetes cluster on Ezmeral Container Platform. You want to use this cluster's Data Fabric to provide persistent storage for other Kubernetes clusters on the platform.

This storage should include automatically generated TenantShares and TenantStorages.

What should you do?

Options:

Set the platform's Tenant Storage to HDFS mode; specify the IP address of the Data Fabric cluster's conductor (master) in the HDFS settings.

Re-run the Ezmeral Container Platform installation file, selecting the "--upgrade" option, and select the embedded Data Fabric option.

Reference the Data Fabric cluster as the underlying cluster for every Kubernetes Tenant that you create.

Use scripts on the controller to prepare, configure, and register the Data Fabric cluster as the Tenant Storage.

Answer

Questions # 5:

You are creating an EPIC Tenant on Ezmeral Container Platform.

When would you grant the Cluster Superuser privilege to Tenant Admins?

Options:

The Tenant Admins need rights to multiple tenants, and you do not want to give these users Site Admin rights.

The Tenant Admins need additional rights to set up persistent storage for certain applications.

The Tenant Admins need to access the App Store and download apps for the tenant.

The Tenant Admins requires root access to run ActionScripts on virtual clusters.

Answer

Questions # 6:

You have an Ezmeral Container Platform solution running v5.2 software. The platform manages several Kubernetes clusters. You need to upgrade the software. What type of behavior should you expect during the upgrade?

Options:

Existing services continue to run with minimal disruption, but users cannot add new services in the Web Ul.

All services on the cluster will be down for about an hour, as will the Web Ul.

Users can access EPIC features, but services running on the Kubernetes cluster will be unavailable.

Users can access the Web Ul. But external clients will not be able to reach services on the cluster.

Answer

Questions # 7:

You have added a deployment object to the "tenant!" namespaces on a Kubetnetes cluster using the "cluster.local" domain name.

The deployment's pods run a Web-based application. You want the application running on these pods to be accessible within the cluster at hostname:

portaLtenantl.svc.clusteUocal.

Which object meets these requirements?

Options:

A service object with ClusterIP type and name "portal"

A replica set object with container ports 80 and 443

A configmap object with ports 80 and 443 and name "portaLtenant l"

A kdcluster object with hostname "portal.tenantl.svc.cluster.local"

Answer

Questions # 8:

Refer to the exhibits.

Question # 8

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?

Options:

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

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

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

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

Answer

Questions # 9:

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.

Options:

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.

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.

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.

Answer

Questions # 10:

What is one requirement tor setting up Platform High Availability (HA)?
