Pure Storage Pure Certified Portworx Enterprise Professional (PEP) Exam 認定 Portworx-Enterprise-Professional 試験問題 (Q31-Q36):

質問 # 31
What configuration steps should a Portworx Administrator perform to ensure that Portworx can use the S3 Object Store using a custom/3rd party (not signed by public CA) certificate?

A. Create a secret containing the certificate and run pxctl certificate import command.
B. No additional configuration is necessary.
C. Create a Kubernetes secret containing the certificate and reference it in the storagecluster via env variable.

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
When integrating Portworx with an S3 Object Store secured by a custom or third-party certificate that is not signed by a public Certificate Authority (CA), administrators must manually provide the relevant CA certificate to Portworx. This involves creating a Kubernetes secret that contains the custom CA certificate and referencing this secret in the StorageCluster manifest through environment variables. This allows Portworx components to trust the certificate during TLS handshake with the S3 endpoint, avoiding connection failures due to untrusted certificates. Without this step, Portworx cannot securely communicate with the object store. The Portworx security and installation documentation highlights this practice as essential for secure Object Store integration in private or regulated environments where internal or custom PKIs are used【Pure Storage Portworx Security Guide source】.

質問 # 32
What happens if the spec.csi.enabled flag is set to false in the Portworx StorageCluster spec?

A. The cluster will fail to deploy if CSI is disabled.
B. CSI will be installed, but it will not be used.
C. CSI will not be installed for the storage cluster.

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
The spec.csi.enabled flag in the Portworx StorageCluster specification dictates whether the Container Storage Interface (CSI) driver is deployed within the Kubernetes environment. Setting this flag to false means that the CSI driver will not be installed or enabled, effectively disabling the CSI functionality. The CSI driver is responsible for dynamic volume provisioning, attachment, and lifecycle management in Kubernetes clusters. Disabling CSI might be necessary in environments relying on legacy volume plugins or specific operational requirements. When CSI is disabled, Portworx will not support dynamic provisioning or other CSI-dependent features, which could limit functionality for Kubernetes storage operations. Portworx operator documentation explicitly states that disabling CSI omits the CSI driver installation, advising users to carefully consider the impact before setting this flag to false, especially in production environments requiring CSI functionality【Pure Storage Portworx Operator Docs source】.

質問 # 33
What command can be used to list all Autopilot rule objects in all namespaces in a Portworx cluster?

A. kubectl get autopilotruleobjects --all-namespaces
B. kubectl describe autopilotrules
C. pxctl list autopilotrules

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
The command pxctl list autopilotrules is used to list all Autopilot rule objects across namespaces within a Portworx cluster. Autopilot rules define automated policies for storage operations like scaling and volume migration. This CLI command queries the Portworx control plane to retrieve and display all configured Autopilot rules, regardless of the Kubernetes namespace they reside in. Using kubectl commands alone is insufficient because Autopilot rules are managed internally by Portworx and may not correspond directly to Kubernetes resources. Official Portworx CLI documentation confirms pxctl list autopilotrules as the primary command for comprehensive Autopilot rule enumeration, enabling administrators to audit and manage storage automation policies efficiently【Pure Storage Portworx Autopilot Guide source】.

質問 # 34
A Portworx administrator wants to create a storage class that can be used to create volumes with the following characteristics:
* Encrypted volume
* Two replicas
Which definition should the administrator use?

A. kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: px-encrypted
provisioner: kubernetes.io/portworx-volume
parameters:
secure: "true"
repl: "2"
B. kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: px-encrypted
provisioner: kubernetes.io/portworx-volume
parameters:
encrypted: "true"
repl: "2"
C. kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: px-encrypted
provisioner: kubernetes.io/portworx-volume
parameters:
sharedv4: "true"
repl: "2"

正解：B

解説：
Comprehensive and Detailed Explanation From Exact Extract:
To create a StorageClass in Kubernetes for Portworx volumes that are encrypted and replicated twice, the correct parameters are encrypted: "true" to enable encryption and repl: "2" to specify two replicas. Option A accurately sets these parameters, ensuring volumes provisioned with this StorageClass will be encrypted at rest and maintain two replicas for data redundancy. Option B uses sharedv4: "true", which relates to NFS-like sharing, not encryption. Option C uses secure: "true", which is not the recognized parameter for enabling encryption in Portworx StorageClass definitions. The official Portworx StorageClass parameter documentation confirms encrypted as the correct flag for encryption and repl to specify replication factor, enabling administrators to enforce data security and availability policies declaratively through Kubernetes manifests【Pure Storage Portworx StorageClass Guide source】.

質問 # 35
What command allows a Portworx admin to create a cloud credential for the Object Store?

A. pxctl credentials generate
B. pxctl service credentials create
C. pxctl credentials create

正解：C

解説：
Comprehensive and Detailed Explanation From Exact Extract:
In Portworx, managing credentials for cloud object stores is vital to enable features like cloud snapshots and backups. The command pxctl credentials create is used to create and register cloud credentials with the Portworx cluster. This command allows administrators to specify provider details such as AWS, Google Cloud, or Azure, and input necessary access keys, secret keys, regions, and endpoints. Proper credential configuration enables Portworx to authenticate with external object stores securely, ensuring reliable data movement and disaster recovery operations. The CLI facilitates easy credential management, including listing, updating, and deleting credentials as needed. Official Portworx documentation highlights pxctl credentials create as the authoritative command for establishing cloud storage access, ensuring security best practices by managing credentials centrally within the Portworx control plane【Pure Storage Portworx CLI Guide source】.
