NO.16 You have used Ezmeral Container Platform to create a Kubernetes cluster, which has 3 conductor (master) nodes tor HA and 12 workers. Which correctly describes how the platform manages this cluster?

The controller elects one conductor as the primary conductor and places the other conductors in standby mode.

The controller places the conductor nodes in standby mode and takes over as the active conductor for the Kubernetes cluster.

The controller sends API requests through the gateway, which load balances them across the conductor nodes.

The controller can manage the cluster, but using HA for the conductors limits a few features such as Data Taps and the Web Terminal.

NO.17 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?

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.

NO.18 What is a use case for Apache Spark?

Processing and analyzing data quickly

Establishing secure communications

Storing data and ensuring data protection

Making Kubernetes easier to manage

NO.19 What is an advantage of HPE Ezmerai Container Platform as compared to engineered Kubernetes distributions such as Red Hat OpenShift?

It keeps better pace with the latest Kubernetes versions and provides a flexible choice in which versions each cluster runs.

It enables customers to run containerized workloads on-prem while most engineered Kubernetes solutions are cloud only.

It is designed to run stateless and stateful apps while most engineered Kubernetes solutions are optimized for stateful apps only.

It provides a lower TCby using an upfront payment model as opposed to software subscriptions.

NO.20 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?

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”

NO.21 Which correctly describes components of the Hadoop framework?

MapReduce compresses data that is stored in HDFS.

YARN provides data protection and management for data within HOF5.

MapReduce applications process data that is stored in HDFS.

YARN is a particular type of application intended for in-memory analytics.

NO.22 What Is one way that HPE EzmeralContainer Platform helps customers to reduce costs?

By making it easy to install bare metal Kubernetes hosts and clusters, it eliminates the costs of many virtualization licenses.

It embeds all control plane functions in the same host systems that run container workers, reducing hardware costs.

It includes its own container orchestration software so that customers do not have to purchase expensive Kubernetes licenses.

It provides a streamlined solution with fewer components than typical DIY Kubernetes, reducing hardware and operational costs.

NO.23 For which use case should you enable Istlo on a Kubernetes cluster?

Preparing complex, stateful applications for deployment on Kubernetes

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

establishing secure communications between components in a microservtce-based application

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

NO.24 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?

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.

NO.25 You are creating an EPIC Tenant on Ezmeral Container Platform.
When would you grant the Cluster Superuser privilege to Tenant Admins?

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.

NO.26 Refer to the exhibit.

What should you keep (n mind as you configure the circled setting?

You must check with network admins and make sure that they have set up routes to these subnets in the data.

You can select any large subnets; these addresses are tunneled with VXLAN and invisible outside the cluster.

You must make sure that the two subnets overlap so that pods can communicate with services.

You must increase the size of these subnets by changing them to use a /24 prefix length.

NO.27 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?

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

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

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

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

NO.28 What ate the network requirements for the HPE Ezmeral Container Platform controller and gateway?

The controller and gateway must be on the same routable network as the Kubernetes or EPIC hosts.

The controller and gateway must be on routable networks, but do not have to be on the same network as each other or other hosts.

The controller and gateway must be on the same routable network as each other, but not necessarily other hosts.

The controller and gateway must be on the same non-routable private network as each other and all other hosts.

NO.29 What Is a correct consideration for creating a Kubernetes Tenant on Ezmeral Container Platform?

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

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

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

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

NO.30 You need to set up email alerts.
When do you need to exec into the Ezmeral Container Platform controller’s “epic-nagios” container, as opposed to using the Web Ul?

When you want to set a custom source email address for the alerts

When the controller DNS server does not have an entry for the destination email domain

When you want to specify multiple destination email addresses and groups

When you want to send an alert to an SNMP version 3 server
