Pure Storage FlashArray-Implementation-Specialist Pure Certified FlashArray Implementation Specialist (FAIS) Exam Exam Practice Test

On FlashArray//XL, the PCIe slot 8 supports installation of 4-port Fibre Channel cards, allowing higher port density for SAN connectivity.

The command purearray phonehome --send-logs is used to send all Phonehome logs to support upon completion of an upgrade.

Ensuring Remote Assist is enabled allows Support to perform remote health checks, and updating the case keeps all parties informed for follow-up.

In FlashArray//XR2 and //XR3 models, the PCIe slot 2 is designated for the installation of a 4-port SAS card. This configuration is essential for connecting to SAS expansion shelves, ensuring proper data path redundancy and performance.

The FlashArray//XL supports up to four DirectFlash Shelves (DFS), each providing up to 1.9PB of effective capacity, enabling a total effective capacity of up to 7.6PB when fully expanded.

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.

The FlashArray//X70R2 and //X90R2 models are equipped with dual 1600W power supplies, each rated for 1600 watts. These high-wattage power supplies are designed to support the increased performance and capacity demands of these models. The power supplies operate in an N+1 redundancy configuration, ensuring continuous operation even if one power supply fails.

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

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.

Drive relocation should be performed only after the XFORM upgrade completes to avoid disrupting the upgrade process and ensure data integrity.

Positioning studs are used to align and secure the rails correctly in a threaded-hole rack, ensuring proper installation and stability of the FlashArray.

When installing the first DirectFlash Shelf on a FlashArray//XR2/3, mezzanine ports ETH6 and ETH9 on the controllers are used for connectivity.

Customers can independently upgrade Purity using the Self-Service upgrade portal on Pure1 Manage, enabling them to proceed without waiting for support scheduling.

The pureboot list command shows the versions of Purity installed and indicates which version will be loaded on the next system boot.

The command purenetwork list --ntpserver displays the configured NTP servers on the FlashArray network settings.

For ActiveCluster with Ethernet replication, a total of 8 IP addresses are typically required; if 3 are already provided, 5 additional IPs are needed to complete the configuration.

Waiting 10 minutes after running puredb run giveback --safe ensures the system completes safe resource rebalancing and stabilizes before proceeding with the next controller upgrade step.

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.

Installing four DirectFlash Modules in a 9.1 TB Conversion Kit is intended to widen an existing write group, improving performance and capacity distribution within the FlashArray.

Reducing SafeMode retention and eradication settings requires approval from two designated SafeMode approvers via Pure1’s step-up authentication to ensure secure and authorized policy changes.

To ensure compatibility and optimal performance, the Implementation Engineer should consult the recommended DFS versions for the installed Purity release and upgrade both the FlashArray and DirectFlash Shelf accordingly.

The command purehost monitor --balance checks the distribution and health of I/O across hosts and initiators, helping verify balanced I/O after a controller upgrade.
