Pass the Pure Storage FAIS FlashArray-Implementation-Specialist Questions and answers with CertsForce

The Ethernet mezzanine on FlashArray//XR2/3 is assigned interfaces starting at ETH8 through ETH11, reflecting the numbering scheme for additional Ethernet ports beyond the base interfaces.

When adding a second DirectFlash Shelf to a FlashArray//XL, PCIe slot 6 is used to connect the additional shelf, complementing slot 0 used by the first shelf.

The command hwconfig --model returns the model information of the controller, which is essential before running the puresetup replace procedure.

Fibre Channel (FC) I/O cards are compatible across all FlashArray models, providing consistent SAN connectivity regardless of array generation.

A swing shelf is installed during the SAS to NVMe Evergreen XFORM upgrade only if the array lacks enough free capacity to evacuate data packs, enabling safe data migration during transformation.

The upgrade kit for an //X to //XL Non-Disruptive Upgrade (NDU) includes 2 QSFP cables, 3 Mellanox InfiniBand cards, and 20 DirectFlash Modules (DFMDs) to support new hardware connectivity and capacity requirements.

To properly configure the proxy server, both the protocol prefix (e.g., http:// or https://) and the port number are required along with the IP address.

On FlashArray//XL, PCIe slots 0 and 6 are designated for DirectFlash Shelf (DFS) connectivity to optimize data throughput and redundancy.

The puredrive admit command is used to complete the admission process for drives showing as "unadmitted," integrating them fully into the FlashArray.

The command pureadm stop --controller CT0 specifically stops Purity on the designated controller (CT0), which is the correct step to safely begin a controller upgrade.
