HP HP Certifications HPE2-N68 Questions & Answers

• Question 21:

  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?

  A. 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.

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

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

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

  Correct Answer: A

• Question 22:

  What is an advantage of HPE Ezmerai Container Platform as compared to engineered Kubernetes distributions such as Red Hat OpenShift?

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

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

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

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

  Correct Answer: A

• Question 23:

  What is one key advantage ofHPE EzmeralData Fabric as opposed to HDFS?

  A. EzmeralData Fabric stores a great deal more metadata than HDFS, making It more resilient.

  B. EzmeralData Fabric uses more efficient erasure coding to protect all data, instead of replication.

  C. EzmeralData Fabric reduces load on storage nodes by placing all metadata on a centralized name node, while HDFS distributes metadata.

  D. EzmeralData Fabric enables admins to set policies at a logical volume level, while HDFS does not.

  Correct Answer: D

• Question 24:

  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?

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

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

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

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

  Correct Answer: A

• Question 25:

  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

  Correct Answer: D

• Question 26:

  Refer to the exhibit.

  

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

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

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

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

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

  Correct Answer: D

• Question 27:

  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.

  Correct Answer: D

• Question 28:

  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.

  Correct Answer: C

• Question 29:

  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

  Correct Answer: D

• Question 30:

  What Is one way that HPE EzmeralContainer Platform helps customers to reduce costs?

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

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

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

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

  Correct Answer: C
