FlashArray-Implementation-Specialist Exam Dumps : Pure Certified FlashArray Implementation Specialist (FAIS) Exam

To verify the history and transmission status of Phonehome log bundles, the correct command is purearray phonehome --list .

Before starting a controller upgrade (NDU), it is mandatory to ensure that the array can successfully transmit diagnostic data to Pure Storage. This allows Support to review the "pre-flight" checks and ensures that if an issue occurs during the upgrade, logs will be available for triage.

Usage: Running purearray phonehome --list displays a table of recent log bundles generated by the system.

Verification: The Engineer must look at the Status column for the most recent entries. A status of "uploaded" confirms that the array has successfully connected to the Pure Storage cloud and transferred the data. If the status is "queued" or "failed," the upgrade should not proceed until network connectivity (firewall/proxy) is resolved. Options A and C are incorrect CLI syntax for this specific verification task.

During a Hardware Non-Disruptive Upgrade (HWNDU) or an offline controller reimaging process, the Implementation Engineer uses the pureinstall utility via the local KVM console to write a new Purity//FA operating system image onto the hardware.

The FlashArray controller boot drives are designed with an A/B partition structure to ensure safe upgrades and easy rollbacks. When the pureinstall < version > .ppkg command successfully completes its execution, it has merely unpacked and written the new Purity OS onto the inactive, alternate boot partition. It does not automatically switch the live operating system.

To finalize the installation and actually boot the controller into the newly installed Purity version, the Implementation Engineer must manually issue a reboot command (typically by typing sudo reboot or simply reboot at the setup prompt).

Upon rebooting, the controller's BIOS will target the newly updated partition, load the fresh Purity kernel, and initialize the system on the new version. Selecting Option B (rebooting the array) is entirely incorrect, as taking down both controllers simultaneously would cause a complete storage outage, violating the fundamental principles of a non-disruptive upgrade. Logging out (Option C) merely closes the console session but leaves the controller running the old OS partition.

When expanding a FlashArray//XR4 with additional DirectFlash Shelves (DFS), discrete PCIe Ethernet/RoCE cards are added to the chassis to provide the necessary backend connectivity. The FlashArray operating system (Purity) enumerates network interfaces sequentially based on slot order and onboard port detection.

On the //XR4 platform, the onboard ports and standard primary expansion slots typically occupy the interface names eth0 through eth5 (depending on the exact transceiver and daughter card configuration, where eth0-3 are often onboard/mezzanine). When a new 2-port expansion card is installed into the designated slot (e.g., Slot 3) to support a second shelf loop, Purity assigns the next available interface identifiers to these physical ports.

In a standard deployment configuration for a second shelf, these new ports are enumerated as ETH6 and ETH7 . The Implementation Engineer should verify these specific interfaces in the GUI or CLI (pureport list) to ensure the card is recognized and to cable the second shelf correctly to these ports, rather than assuming they will be eth4/5 which might be assigned to the first shelf or other internal functions.
