Using HPE Containers
Question 1
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.
Answer:
A
Question 2
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.
Answer:
D
Question 3

- B. When the controller DNS server does not have an entry for the destination email domain
- C. When you want to specify multiple destination email addresses and groups
- D. When you want to send an alert to an SNMP version 3 server
Answer:
B
Question 4
What is one benefit that HPE Ezmeral Container Platform provides for loT deployments?
- A. It supports Edgeline servers, which are specialized for the edge, as hosts within the platform.
- B. It provides APIs for deploying the platform services on mobile devices.
- C. Its control plane runs in the HPE cloud, which brings the scalability required for lot
- D. It supports importing third-party loT platforms as clusters managed by the platform.
Answer:
B
Question 5
What is one key advantage of HPE Ezmeral Data Fabric as opposed to HDFS?
- A. Ezmeral Data Fabric stores a great deal more metadata than HDFS, making It more resilient.
- B. Ezmeral Data Fabric uses more efficient erasure coding to protect all data, instead of replication.
- C. Ezmeral Data Fabric reduces load on storage nodes by placing all metadata on a centralized name node, while HDFS distributes metadata.
- D. Ezmeral Data Fabric enables admins to set policies at a logical volume level, while HDFS does not.
Answer:
D
Question 6
What is one requirement tor using the pre-check config rite to install HPE Ezmeral Container Platform
v5.2 on a controller host?
- A. You must first install a digital certificate to secure management communications with the host.
- B. The host must pass all the checks run by the pre-check config script.
- C. You must run the standard installation before running the pre-check config file.
- D. The host must run the RHEL operating system because SLE5 is not supported.
Answer:
C
Question 7
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?
- A. Existing services continue to run with minimal disruption, but users cannot add new services in the Web Ul.
- B. All services on the cluster will be down for about an hour, as will the Web Ul.
- C. Users can access EPIC features, but services running on the Kubernetes cluster will be unavailable.
- D. Users can access the Web Ul. But external clients will not be able to reach services on the cluster.
Answer:
C
Question 8
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. A service object with ClusterIP type and name "portal"
- B. A replica set object with container ports 80 and 443
- C. A configmap object with ports 80 and 443 and name "portaLtenant l"
- D. A kdcluster object with hostname "portal.tenantl.svc.cluster.local"
Answer:
A
Question 9
You are using native Kubernetes, and you want to deploy three identical containers. What Is the
recommended way to do so?
- A. Create a deployment object that specifies three replicas of a pod. which defines the desired container settings.
- B. Create a pod object that specifies three separate containers; specify the same settings for each container.
- C. Create one container object. Then specify three instances of that object in a separate pod object.
- D. Create three container objects. For each object specify the same image and settings.
Answer:
A
Question 10
What Is the arbiter's role in the HPE Ezmeral Container Platform?
- A. Direct the shadow controller to begin managing the platform if the controller fails
- B. Monitor the gateway and notify the administrator if a critical error occurs
- C. Detect if the controller or shadow controller has failed and begin managing the platform
- D. Load balance requests sent to the controller and shadow controller
Answer:
A
Question 11
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.
Answer:
A
Question 12
What Is the purpose of the training stage in the ML lifecycle?
- A. The ML application applies a model to the data and tests the effectiveness of that model.
- B. The ML application gathers data and applies an algorithm to prepare the data for use.
- C. The ML algorithm assesses different datasets and selects the best data for use in later stages.
- D. The ML algorithm processes a dataset and learns to perform a task.
Answer:
B
Question 13
Which correctly describes components of the Hadoop framework?
- A. MapReduce compresses data that is stored in HDFS.
- B. YARN provides data protection and management for data within HOF5.
- C. MapReduce applications process data that is stored in HDFS.
- D. YARN is a particular type of application intended for in-memory analytics.
Answer:
C
Question 14
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.
Answer:
A
Question 15

- 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
