NEW QUESTION # 58
An Implementation Engineer has completed a hardware NDU, but after the upgrade, Purity reports a "health not responding" status when running status. Before contacting support, which command should the Implementation Engineer run to review a list of possible logged issues?
Answer: A
Explanation:
After a complex operation like a Hardware Non-Disruptive Upgrade (HWNDU), the Purity health services may occasionally stall or report generic errors like "health not responding." Standard alert commands (purealert list) might be empty or show generic "service unavailable" messages because the alerting service itself depends on the health system.
To troubleshoot this, the Implementation Engineer should dig deeper into the system's internal message log using puremessage list --open --hidden.
puremessage accesses the raw message bus of the array, which captures lower-level events than standard alerts.
--hidden is the critical flag here; it reveals internal system messages that are typically suppressed from the standard user view to avoid noise.
These hidden messages often contain the specific error codes or service failure reasons (e.g., "timeout waiting for daemon X") that explain why the health status is hanging. Providing this output to Pure Support significantly accelerates the root cause analysis. purearray diagnose is not a standard command for this purpose, and purealert watcher is for configuring notification recipients, not viewing log contents.
NEW QUESTION # 59
Prior to running the puresetup command, which command should an Installation Engineer run on a new install of a FlashArray//XR4 array?
Answer: A
Explanation:
The FlashArray//XR4 introduces a new hardware platform architecture (internally codenamed or associated with "Cobalt" components for its BMC and chassis management). During the manufacturing and initial deployment phase, specific validation scripts are used to ensure the platform hardware is correctly initialized before the Purity Operating Environment takes over.
For a new install of a FlashArray//XR4, the Implementation Engineer is often required to run cobalt check .
py (or cobalt_check.py).
* This engineering-level Python script queries the Baseboard Management Controller (BMC) and internal sensors to verify that the chassis components, fans, and power delivery systems are reporting "Healthy" status specifically for the R4 architecture.
* Running this before puresetup prevents the setup process from failing midway due to a hardware initialization error. It acts as a "pre-flight" hardware validation specific to the R4 generation's new chipset and management subsystem.

NEW QUESTION # 60
When adding a data pack into a FlashArray chassis or a DFS shelf, the drives show "unrecognized" status when running List. What is the cause of this status on the newly inserted drives?
Answer: B
Explanation:
The status "unrecognized" on a drive module typically indicates that the physical hardware is detected by the chassis midplane, but the operating system (Purity) does not have the necessary driver definition or firmware logic to interact with it.
This most commonly occurs when newer generation DirectFlash Modules (e.g., larger capacity drives or newer NAND revisions) are inserted into an array running an older version of Purity. The hardware identifier of the new drive is unknown to the older software .
To resolve this, the Implementation Engineer must verify the Purity Compatibility Matrix for the specific drive part number. The array will likely need a Purity software upgrade to a version that supports the new media before the drives can be successfully admitted and used. It is rarely a hardware fault (which would show as "failed" or "missing") or a capacity limit (which would prevent admission but usually identify the drive correctly).

NEW QUESTION # 61
An Implementation Engineer is getting ready to install four DFMs into a 16-module efficiency bundle and notices that the new modules are DFMDs while the installed modules are DFMs. What should the Implementation Engineer do to get the array using a 20-module Wide write group?
Answer: C
Explanation:
FlashArray performance and capacity efficiency are optimized when drives are grouped into "Wide Write Groups" (typically 20 modules). Purity OS generally enforces strict homogeneity within a write group to ensure consistent performance and reliability. Specifically, mixing standard DirectFlash Modules (DFM) with DirectFlash Modules with Distributed NVRAM (DFMD) in the same write group is restricted by default because of the architectural differences in how they handle persistent memory and I/O acknowledgment.
However, in upgrade scenarios where a customer is expanding an existing 16-module DFM group to a 20- module group using newer DFMD spares or expansion packs, Purity includes an engineering tunable to permit this mixed configuration. The correct procedure is to physically install the new DFMDs and run the admission command. Because of the mix, the array might initially hesitate or create a separate group. To force the creation of a single 20-drive Wide Write Group (WWG) , the Implementation Engineer must work with Pure Storage Support to apply the specific tunable puretune --set ALLOW_DFMD_IN_DFM_WWG 1 .
This overrides the default restriction, allowing the system to merge the disparate module types into a single, high-efficiency capacity pool.

NEW QUESTION # 62
The Pure Engagement Request (PER) specifies that iSCSI ports ETH2 and ETH3 should be set to 10 Gb/s. After configuring the ports and connecting them to the SAN, the Implementation Engineer observes that ETH2/3 are not negotiating and display 0 b/s. The SAN is operating at 40 Gb/s, with support for up to 100 Gb/s. What should the Implementation Engineer do to resolve this issue and complete the install?
Answer: B
Explanation:
This scenario describes a physical layer mismatch between the FlashArray optics and the customer's switch infrastructure.
The PER (planning document) specified 10 Gb/s, so the Implementation Engineer likely installed 10 Gb SFP+ transceivers into the array.
The SAN Switch is operating at 40 Gb/s (likely using QSFP+ ports).
You cannot simply "force negotiate" a 10Gb SFP+ optic to run at 40Gb/s, nor can you plug a 10Gb SFP+ directly into a 40Gb QSFP+ port without specific breakout cables or QSA adapters that match the signaling. The physical transceivers themselves are incompatible with the link speed required by the switch.
To resolve this, the Implementation Engineer must replace the transceivers with the appropriate type.
If the switch is 40Gb native, the array needs 40Gb (QSFP+) optics (if supported on that slot).
Alternatively, if the customer intends to use 10Gb, they must provide 10Gb ports on their switch side.
Given the prompt implies the SAN is 40Gb, the 10Gb optics in the array are the incorrect hardware for that link.
