Pure Storage Pure Certified Portworx Enterprise Professional (PEP) Exam Sample Questions (Q29-Q34):

NEW QUESTION # 29
After enabling security in Portworx, the pxctl command returns an "access denied" error.
What action must be taken to allow pxctl to gain access again?

A. Pass both the --user and --password command line flags to the pxctl command. Username and password combination can be found in the px-admin-token secret.
B. The administrator must create a new pxctl context by running pxctl context create and passing the -token command line parameter.
C. Authentication is impossible because an authentication token was not generated before enabling security on the cluster.

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When security is enabled in Portworx, all commands, including those issued via the pxctl CLI, require authentication to access the cluster. If pxctl returns an "access denied" error, it means the CLI does not have valid credentials. To regain access, administrators must provide authentication details using the --user and --password flags or configure a context with an authentication token. The username and password are stored securely within the Kubernetes secret px-admin-token. Using these credentials ensures pxctl commands are authorized to perform management operations. Without authentication, Portworx enforces strict access controls to protect sensitive storage operations and data. While creating new contexts via pxctl context create is a valid method, initially supplying credentials is mandatory. Failure to authenticate prevents any management activity, reinforcing Portworx's security posture. Official security guides outline these steps as fundamental to transitioning from unsecured to secured cluster operation and managing authenticated access effectively【Pure Storage Portworx Security Guide source】.

NEW QUESTION # 30
What information is included in the Portworx diagnostics bundle (diags)?

A. User activity logs, security policies, and firewall rules
B. Application logs, Kubernetes events, and network configurations
C. Portworx journal logs, CLI command outputs, and basic OS information

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Portworx diagnostics bundle, known as "diags," aggregates comprehensive diagnostic data for troubleshooting. This includes Portworx journal logs, which record detailed system and service events essential for identifying errors or malfunctions. Additionally, the bundle contains outputs from key CLI commands such as pxctl status and pxctl volume list that provide snapshots of the cluster's health, volume states, and configuration at the time of collection. Basic operating system information, including kernel version, disk hardware details, and network interfaces, is also captured to understand the underlying environment. Together, these components equip Portworx support and administrators with the contextual data needed for effective root cause analysis and faster issue resolution. The official Portworx support documentation recommends collecting and submitting this bundle for all significant troubleshooting cases as it expedites problem diagnosis and resolution【Pure Storage Portworx Support Guide source】.

NEW QUESTION # 31
What feature does a Portworx StorageClass provide to Kubernetes storage?

A. Automated backups
B. Automated monitoring
C. Automated storage provisioning

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In Kubernetes, StorageClasses define how persistent volumes are dynamically provisioned. A Portworx StorageClass enables automated provisioning of Portworx volumes in response to Persistent Volume Claim (PVC) requests. This eliminates the need for administrators to manually create volumes, improving agility and scalability. The StorageClass encapsulates volume parameters such as replication factor, encryption, and IO profiles, ensuring consistent storage policies across deployments. While Portworx offers monitoring and backup capabilities, these are outside the scope of the StorageClass resource itself. Kubernetes and Portworx documentation detail the StorageClass as a critical abstraction for enabling self-service storage provisioning, allowing applications to request storage with specific attributes dynamically and Portworx to satisfy these requests seamlessly【Pure Storage Portworx Kubernetes Guide source】.

NEW QUESTION # 32
What Portworx swap requirement exists on a Portworx-enabled Linux host?

A. Swap should be enabled.
B. Portworx does not have a requirement for swap to be enabled or disabled.
C. Swap should be disabled.

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Portworx requires swap to be disabled on Linux hosts where it runs. Disabling swap is necessary because swap usage can cause unpredictable latency and performance degradation for storage operations. Portworx relies on consistent and predictable I/O performance for managing block devices and volumes, which is incompatible with the potential delays caused by swapping memory pages to disk. Additionally, many Kubernetes environments recommend disabling swap to meet Kubernetes scheduler requirements, aligning with Portworx's needs. Portworx installation and system requirements documentation explicitly state that swap should be disabled on nodes running Portworx to ensure cluster stability, optimal performance, and predictable behavior of storage operations【Pure Storage Portworx System Requirements source】.

NEW QUESTION # 33
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.

Answer: C

Explanation:
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】.
