質問 # 167
An Implementation Engineer is scheduled to install a FlashArray and a DirectFlash Shelf (DFS). What action should the Implementation Engineer perform?
正解:A
解説:
The correct action is to refer to the "Recommended DFS Versions for Purity Releases" Knowledge Base (KB) article and, if necessary, upgrade the Purity software on the FlashArray (which updates the DFS firmware).
Compatibility: DirectFlash Shelves (DFS) run specific firmware that must be compatible with the Purity operating system running on the array controllers. If a new shelf is shipped with very recent firmware, or an old shelf is added to a new array, there may be a mismatch.
Best Practice: The "Recommended DFS Versions" KB is the definitive source of truth. The engineer must verify if the shipped Purity version supports the specific hardware revision of the shelf.
Procedure: If an upgrade is required, the engineer updates Purity on the array. Since the DFS firmware is bundled within the Purity release, upgrading the array (Option A) effectively stages the update for the shelf. Once the shelf is attached (or if attached during the upgrade), Purity automatically applies the correct firmware to the DFS modules. Skipping this check (Option B) or blindly upgrading without cross-referencing the KB (Option C) risks connectivity issues or unrecognized capacity.
質問 # 168
After completing an HWNDU, what command should an Implementation Engineer run to confirm if any open alerts are transitioning to a 'closing' status?
正解:A
解説:
During and after a Hardware Non-Disruptive Upgrade (HWNDU), the FlashArray may generate various alerts related to component removals, path failovers, or temporary redundancy reductions. Once the upgrade is physically complete and the software has stabilized, the Implementation Engineer must verify that the array has returned to a fully healthy state.
The command purealert list is the primary tool for this verification. It displays the current table of active alerts on the system.
* If the array is healthy, this list should be empty or contain only "Info" level messages.
* If the system is still recovering, you might see alerts with a status indicating they are "closing" or
"downgrading" as the conditions resolve (e.g., "Controller redundancy restored").
pureaudit list shows the history of user commands, not system health alerts. puremaintenance is not a standard command for checking alert status. Therefore, purealert list is the correct command to validate that no critical hardware or software issues remain active after the maintenance window.
質問 # 169
During a FlashArray//XR5 upgrade, when should the Implementation Engineer run start_ndu controller-ndu to set the HWNDU specific tunable?
正解:B
解説:
When executing a Hardware Non-Disruptive Upgrade (HWNDU) to a new chassis generation, such as moving to a FlashArray//XR5, the new controllers must be properly prepped to join the existing, older- generation cluster. The correct sequence of operations is critical to prevent the cluster from rejecting the mismatched hardware.
Once the new //XR5 controller is physically inserted into the slot of the removed older controller, the Implementation Engineer must first install the correct target version of the Purity//FA operating system locally using the pureinstall command via the KVM console. After Purity is successfully installed, but strictly before the controller is logically initialized to join the cluster (via the puresetup secondary command), the engineer must execute the start_ndu controller-ndu script.
This script applies specific internal HWNDU tunables-such as relaxing hardware mismatch checks, bypassing specific alert monitors, and adjusting heartbeat timeouts. Setting these tunables ensures that when the controller is finally initialized, the surviving primary controller safely accepts it as a valid secondary partner without triggering a system fault, hardware rejection, or disrupting active host I/O.
質問 # 170
Prior to installing a new FlashArray controller, which terminal display settings must the Implementation Engineer configure?
正解:B
解説:
Establishing a serial console session is a fundamental step for initializing a new FlashArray or troubleshooting boot issues. To successfully communicate with the FlashArray controllers via the DB9 or Micro-USB serial port, the terminal emulator (such as PuTTY or TeraTerm) must be configured with specific parameters.
The verified standard settings for all modern FlashArray controllers are:
Baud Rate: 115,200 (This is faster than the legacy 9600 standard used on older network gear).
Data Bits: 8
Parity: None (N)
Stop Bits: 1
Flow Control: Xon/Xoff (Software flow control is preferred over hardware RTS/CTS).
Configuring these settings incorrectly (e.g., wrong baud rate) will result in garbled text ("garbage characters") or a completely blank screen when connecting to the console, preventing the engineer from running the puresetup initialization script.
質問 # 171
Which PCIe slot supports 4-port FC cards on FlashArray//XL?
正解:C
解説:
On FlashArray//XL, the PCIe slot 8 supports installation of 4-port Fibre Channel cards, allowing higher port density for SAN connectivity.
