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

• KubeDlrector embeds a ticket-based authentication system to enhance security for communications across stateful sets.
  
• 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.
  
• KubeDlrector has a flexible framework that can work for many stateful apps, and Is easier for non-Kubernetes experts to use.
  
• KubeDirector is optimized for establishing secure service meshes across cloud-scale, stateless, micro-service-based architectures.
  

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

• 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
  

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.
  

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?

• 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.
  

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

• Create a Volume to link to the PV.
  
• Create a Persistent Volume Claim (PVC).
  
• Create a PV definition on a backend storage array.
  
• Enable persistency in the Kubernetes namespace.
  

Your company has developed a JSON file to define a custom KubeDirector application.What step should you take to add the application to the catalog available to a Kubernetes Tenant?

• As a Tenant Member or Admin, use the Web Terminal or HPE Kubectl plug-in to issue the kubectl apply -f command.
  
• As a Site Admin, import the JSON file using the Web Ul. Then enable the application within the Tenant settings.
  
• As a Tenant Admin, use Helm to download the JSON file as a chart. Then deploy the chart as a release within the tenant.
  
• As a Site Admin, place the file in the controller /srv/bluedata/catalog directory; modify permissions on the file to make it accessible in the Ul.
  

What is one requirement tor using the pre-check config rite to install HPE Ezmeral Container Platform v5.2 on a controller host?

• You must first install a digital certificate to secure management communications with the host.
  
• The host must pass all the checks run by the pre-check config script.
  
• You must run the standard installation before running the pre-check config file.
  
• The host must run the RHEL operating system because SLE5 is not supported.
  

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?

• Enable the embedded Data Fabric during the controller install. Create hybrid Kubernetes clusters that use Data Fabric and non-Data Fabric nodes.
  
• Enable the embedded Data Fabric during the controller install. Also create a dedicated Data Fabric Kubernetes cluster.
  
• Disable the embedded Data Fabric during the controller install. Create a dedicated Data Fabric Kubernetes cluster.
  
• Disable the embedded Data Fabric during the controller install. Create hybrid Kubernetes clusters that use Data Fabric and non-Data Fabric nodes.
  

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.
  

What Is the purpose of the training stage in the ML lifecycle?

• The ML application applies a model to the data and tests the effectiveness of that model.
  
• The ML application gathers data and applies an algorithm to prepare the data for use.
  
• The ML algorithm assesses different datasets and selects the best data for use in later stages.
  
• The ML algorithm processes a dataset and learns to perform a task.
