The 8972-byte ping test fails when any hop lacks the required 9000-byte jumbo MTU for NVMe/TCP; setting MTU 9000 on all interfaces resolves connectivity.

A. NVMe/TCP services are enabled by default; issue lies in network MTU, not array features.

C. Running the ping from the target will fail until MTU mismatches are corrected.

Meta fingerprinting is the process in which Purity sends anonymized metadata “fingerprints” to Pure1 META. Pure1’s cloud-based machine-learning models analyse those fingerprints to forecast capacity, detect anomalies, and open proactive support cases—delivering predictive support to customers.

A. RA encryption/authentication is handled by TLS certificates, not meta fingerprinting.

B. “Fingerprint” here is a data-pattern hash, unrelated to biometric security.

ActiveDR's test failover feature is designed to be non-disruptive to ongoing replication. When a test is initiated, Purity creates a temporary, writable copy of the target pod, known as an "undo pod." This undo pod is what is presented to the test hosts. All I/O operations during the test are directed to the undo pod, which isolates the testing activity. The original target pod remains untouched and continues to receive replication data from the source array, ensuring the test does not impact the recovery point objective (RPO).

A. The content from the last periodic refresh: ActiveDR is near-synchronous, not based on periodic refreshes. The test uses a point-in-time copy from when the test was initiated.

B. The content from the last real fail-over: A test failover is independent of any prior real failovers and uses the current replicated data, not data from a past disaster recovery event.

For true real-time data and alerts, the information must be sourced directly from the FlashArray. The FlashArray provides instantaneous performance metrics and status updates with minimal latency through its built-in Purity//FA operating environment. NOC dashboards and other real-time monitoring tools can query the FlashArray's REST API or use SNMP traps to get the most current, up-to-the-second information. This direct access bypasses the latency associated with cloud-based aggregation platforms.

A. "Pure Performance Monitoring" is a generic term, not a specific product. The actual source of the data is the FlashArray itself.

B. Pure1 is a cloud-based analytics and management platform. It collects telemetry periodically, so its data is near-real-time but not instantaneous due to processing and transmission delays.

When new DirectFlash Modules (DFMs) are physically inserted into a FlashArray chassis, they are not automatically incorporated into the storage pool. An administrator must explicitly "admit" them into the array using the Purity Command Line Interface (CLI). The correct command syntax is puredrive admit. This command initiates the process of testing the new module and, if it passes, integrating it into the Purity//FA environment, making its capacity available to the system.

A. pureadmin -- admit-drive: pureadmin is not a valid Purity//FA command. The standard CLI commands follow the pure
