Nutanix NCP-CN : Nutanix Certified Professional - Cloud Native v6.10

An ecommerce company decides to apply an autoscaling configuration in its NKP cluster due to the fact that on holidays, they experience service drops due to a huge increase of simultaneous traffic.
Which statement best describes the configuration shown in the exhibit?

• A. The autoscaler could have 15 or 3 nodes.
• B. The autoscaler could increase the number of nodes up to 3, but never reduce it below 15.
• C. The autoscaler could increase the number of nodes up to 15, but never reduce the number below 3.
• D. The autoscaler could increase the number of nodes as needed, but never reduce it below 3.

A dev team needed to optimize their logging system to be more robust, because the CPU and memory limits were insufficient, which caused delays in log collection and processing during times of high demand.
After a deep performance analysis, they decided to increase the CPU limits from 1 to 4 and the memory from
1000Mi to 4Gi.
Which ConfigMap should the development team run with custom resource requests and limit values for fluentd?

• A. bash
  Copy
  [nutanix@nkp-boot ~]$ cat <<EOF > configmap.yaml
  apiVersion: v1
  kind: ConfigMap
  metadata:
  name: logging-operator-logging-overrides
  namespace: kommander
  data:
  values.yaml: |
  fluentd:
  resources:
  limits:
  cpu: 4
  memory: 4Gi
  requests:
  cpu: 4
  memory: 4Gi
  EOF
• B. bash
  Copy
  [nutanix@nkp-boot ~]$ cat <<EOF > configmap.yaml
  apiVersion v1
  kind ConfigMap
  metadata
  name logging-operator-logging-overrides
  namespace kommander
  data
  values.yaml |
  fluentd
  resources
  limits
  cpu 1
  memory 1000Mi
  requests
  cpu 4
  memory 4Gi
  EOF
• C. bash
  Copy
  [nutanix@nkp-boot ~]$ cat <<EOF > configmap.yaml
  apiVersion: v1
  kind: ConfigMap
  metadata:
  name: logging-operator-logging-overrides
  namespace: kommander

  fluentd

  cpu 4
  memory 1000Mi

• D. bash

  apiVersion v1
  kind ConfigMap

  name logging-operator-logging-overrides
  namespace kommander

In a financial company, a DevOps team is responsible for supporting all of the company's critical applications. Although the team was experienced, the manual management for cluster health checking was becoming increasingly complicated and prone to errors.
The team consulted its company's Platform Engineer on how to best address these issues. They told the engineer that events such as these were occurring
1.Omitting pod security standards.
2.Crashlooping cases.
3.Failed nodes when deploying or running kube-bench.
What recommendation should the engineer provide to the DevOps team?

• A. Run the nkp describe cluster --cluster-name=${CLUSTER_NAME} command.
• B. Create a MachineHealthCheck resource in YAML format.
• C. Use override ConfigMaps to configure alert rules.
• D. Use AlertManager and NKP Insights together.

Looking at the nodepools for the Kubernetes cluster named demo, there is a node pool named md-1 with only one worker. This worker should be deleted along with the node pool md-1.
How should this task be accomplished?

• A. Run ncli vm.delete demo-md-1-hQ2sz-mw4p6-fptc
• B. Run acli vm.delete demo-md-1-hQ2sz-mw4p6-fptc
• C. Run nkp delete nodepool md-1 --cluster-name=demo
• D. Run nkp node scale nodepool md-1 --replicas=0 --cluster-name=demo

There is a private registry for the NKP deployment and the company has an NKP Ultimate license. A Platform Engineer is using the Podman tool and is already logged in. Now, the engineer needs to send the private registry with the NKP Catalog Applications.
What command should the engineer use?

• A. nkp apply bundle -f ./container-images/nkp/catalog-applications-image-bundle-v2.12.0.tar --to- registry=${REGISTRY_URL} --to-registry-username=${REGISTRY_USERNAME} --to-registry- password=${REGISTRY_PASSWORD}
• B. podman load -i ./container-images/nkp/catalog-applications-image-bundle-v2.12.0.tar
• C. nkp push bundle --bundle ./container-images/nkp/catalog-applications-image-bundle-v2.12.0.tar --to- registry=${REGISTRY_URL} --to-registry-username=${REGISTRY_USERNAME} --to-registry- password=${REGISTRY_PASSWORD}
• D. docker load -i ./container-images/nkp/catalog-applications-image-bundle-v2.12.0.tar
