FlashArray-Implementation-Specialist Pure Certified FlashArray Implementation Specialist (FAIS) Exam Question and Answers

The purearray remoteassist --connect command explicitly enables Support to establish a remote connection to the array for troubleshooting or assistance.

To upgrade from Purity 5.3.8 to 6.1.21 on a new array, the Implementation Engineer should create a bootable USB installer from the target ISO and reimage both controllers to ensure a clean and supported upgrade.

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

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

The FlashArray//XL models are designed to fit into a 5U rack space, which is equivalent to 5 rack units. Each rack unit (U) is 1.75 inches in height, so a 5U chassis would be 8.75 inches tall. However, the FlashArray//XL chassis is designed to be 5U in height, providing a compact and efficient form factor for enterprise storage needs.

When replacing SAS chassis data packs with DirectFlash Modules (DFMs) after an upgrade to //X20R3-EMEZZ, a DFM Swing Shelf is required to facilitate data evacuation and migration during the transition.

Cage nuts should be placed in the lowest square hole of the lowest rack unit (RU) where the array rails will be installed to ensure proper alignment and support.

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 command purehw list --enclosures displays detailed information about shelf enclosures and their cable connections, helping verify physical connectivity.

Upgrading from FlashArray X10 to X50 requires upgrading power supplies to meet the higher power demands of the larger chassis and expanded hardware.

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.

Running cobalt_check.py on a new //XR4 array verifies hardware and system readiness before executing puresetup newarray, ensuring a smooth setup process.

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.

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.

On an XR2/3 array, a 4-port Fibre Channel card installed in slot 1 is assigned interface names FC4 through FC7, continuing the numbering sequence from other installed FC ports.

Before evacuating a shelf on a FlashArray/M50, usable capacity should be below 80% to provide enough free space for safe data migration.

The correct consolidation process involves evacuating data from the existing chassis drives first, then installing the new larger 91TB data pack, and finally evacuating shelf 0 to complete the consolidation efficiently.

The puredrive list --pack command shows detailed information about the specified data pack, including whether its drives are part of a wide write group.

FC cards from an M-series array can be reused in XR2 or XR3 controllers, allowing hardware continuity during controller upgrades.
