Pure Certified Portworx Enterprise Professional (PEP) Exam Questions and Answers
Question 21
What does an administrator need to do if a drive fails and the pool contains metadata?
Options:
A.
Decommission the node.
B.
Delete the pool.
C.
Reformat the disk and reuse it.
Answer:
A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
If a drive fails and the associated storage pool contains critical metadata, the safest and recommended action is to decommission the entire node. Metadata loss can compromise the integrity of volume allocations and cluster state. Decommissioning the node allows Portworx to safely remove the node from the cluster, replicate data, and redistribute workloads, preventing data loss or corruption. Deleting the pool or reformatting the disk without proper precautions risks losing metadata and causing cluster inconsistencies. Portworx’s operational guidelines emphasize that nodes with failed drives holding metadata require careful decommissioning procedures to maintain cluster health and data durability, ensuring data is rebalanced and availability is preserved【Pure Storage Portworx Operations Guide†source】.
Question 22
What does the DriveStateChange alert indicate?
Options:
A.
Free volume space going below the recommended level of 5%
B.
Free disk space going below the recommended level of 10%
C.
Free disk space going below the recommended level of 20%
Answer:
B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The DriveStateChange alert in Portworx indicates that free disk space on a storage device has fallen below the recommended threshold of 10%. This alert warns administrators that storage capacity on a particular disk is critically low and that immediate action may be needed to avoid performance degradation or failures. Monitoring disk space is essential to maintain cluster health and prevent data loss. Portworx automatically generates this alert as part of its proactive monitoring system, providing early warning so operators can add capacity, remove unnecessary data, or re-balance workloads. The alert documentation advises maintaining sufficient free space to ensure optimal performance and data durability in the Portworx cluster【Pure Storage Portworx Alerting Guide†source】.
