NEW QUESTION # 90
An Implementation Engineer arrives on site to complete a shelf evac. What action must take place before Pure Support can run the completion commands?
- A. Enable Remote Assist (RA).
- B. Set maintenance tag.
- C. Disconnect the SAS or NVMe cables.
- D. Power off the shelf.
Answer: A
Explanation:
A "shelf evacuation" is a non-disruptive capacity consolidation feature. When a customer upgrades to denser flash modules or decommissions older hardware, the Purity operating system transparently migrates all active data blocks off the target DirectFlash Shelf and redistributes them onto the remaining chassis capacity.
Once the GUI and CLI report that the evacuation is 100% complete and the drives are officially empty, the physical data migration is done. However, the Implementation Engineer cannot simply power off the shelf and rip out the cables. The FlashArray's internal database and topology map still retain historical references, WWNs, and hardware associations to that specific shelf and its empty drive bays.
To cleanly purge the shelf from the cluster's active topology and prevent persistent "missing hardware" alerts, Pure Storage Support must execute restricted, backend completion commands (such as the hidden purehw shelf remove script). Because these commands are locked behind advanced engineering privileges, the onsite Implementation Engineer must explicitly Enable Remote Assist (RA) . Remote Assist opens a secure, outbound SSH tunnel from the array's Callhome Connection Manager directly to the Pure Storage support cloud, allowing the remote engineer to log in, run the cleanup scripts, and give the onsite engineer the final green light to physically disconnect the hardware.
NEW QUESTION # 91
The Customer's Implementation Workbook specifies that the SMTP reply is "outlook.microsoft.com:587". What correction should be made for array initialization to be successful?
- A. Provide username and password.
- B. Prefix the URL with "https://".
- C. Remove the port number.
Answer: C
Explanation:
To successfully initialize the FlashArray, the Implementation Engineer should remove the port number from the SMTP relay host field.
During the initial setup (via the Purity GUI wizard or CLI), the system requests a "Relay Host" for email alerts. The input field typically expects a valid Fully Qualified Domain Name (FQDN) or IP address (e.g., outlook.office365.com or smtp.example.com).
Syntax Error: Appending the port number (e.g., :587) to the hostname often causes a DNS resolution failure or a syntax error because the array's initialization parser treats the entire string (including the colon and numbers) as the hostname.
Port Configuration: While modern Purity versions support custom SMTP ports (like 587 for TLS), this is often configured after the initial network setup or requires a specific command syntax that separates the host and port. For the purpose of passing the initial "New Array" setup wizard, providing the clean hostname is the standard correction. The engineer can then refine the SMTP settings (adding authentication and specific ports) in the Purity GUI once the array is initialized and accessible.
NEW QUESTION # 92
Which enablement feature will cause Mirrored Write statistics to appear in the Analysis section of the FlashArray Purity 6.x GUI?
- A. ActiveDR
- B. FA File
- C. ActiveCluster (AC)
Answer: C
Explanation:
Mirrored Write statistics appear in the Purity GUI's Analysis section when ActiveCluster is enabled, as it tracks synchronous replication activity between clusters.
NEW QUESTION # 93
Which I/O card type is compatible across all FlashArray models?
- A. 10GBaseT
- B. FC
- C. iSCSI
Answer: B
Explanation:
Fibre Channel (FC) I/O cards are compatible across all FlashArray models, providing consistent SAN connectivity regardless of array generation.
NEW QUESTION # 94
On a FlashArray//X50 R2/R3 Fibre Channel (FC) array, what is the default type and placement of the PCIe FC card?
- A. 2-port in slot 0
- B. 4-port in slot 0
- C. 2-port in slot 2
Answer: B
Explanation:
For the FlashArray//X50 R2 and R3 models, the default Fibre Channel (FC) configuration utilizes a 4-port PCIe Fibre Channel card installed in Slot 0 .
The hardware architecture of the FlashArray//X series differentiates slot usage based on the model controller chassis.
* FlashArray//X10 and //X20: These lower-end models utilize Slot 2 for host connectivity (Fibre Channel or iSCSI) because Slots 0 and 1 are typically reserved or occupied by onboard controllers
/mezzanine cards. The standard card for these models is often a 2-port card.
* FlashArray//X50, //X70, and //X90: These mid-to-high-range models feature a different PCIe bus layout. Slot 0 is the primary designated slot for Host I/O connectivity. To support the higher performance capabilities and port density requirements of the X50, Pure Storage defaults to 4-port FC cards (typically 16Gb or 32Gb).
Therefore, identifying the model number is crucial. Since the question specifies the X50 (R2/R3), the correct placement is Slot 0, and the correct card type is the 4-port model. Option A is incorrect because the 2-port card is not the standard default for the performance-tier X50. Option B describes the configuration for an X20, not an X50.
NEW QUESTION # 95
After performing a hardware upgrade from an //M20R2 to a //X20R3-EMEZZ, a customer wants to add a Direct Flash Modules data pack to replace the existing SAS Chassis Data Packs (2x 20TB DPs). What extra hardware is required?
- A. DFM Swing shelf
- B. SAS Swing shelf
- C. 4-port ETH card
Answer: B
Explanation:
To perform this specific "SAS-to-NVMe" media refresh during an upgrade, a SAS Swing Shelf is required.
The scenario describes a transition from a FlashArray//M (SAS-based chassis) to a FlashArray//X (NVMe-based chassis). The customer intends to retire the old SAS SSDs (the "SAS Chassis Data Packs") and move to new DirectFlash Modules (DFMs).
The Constraint: The old SAS drives physically cannot be inserted into the new //X NVMe chassis.
The Workflow: To migrate the data, the old SAS drives must be temporarily attached to the new //X controller as external capacity. Since they were originally internal chassis drives, they have no enclosure. Therefore, the engineer needs an empty SAS expansion shelf (Swing Shelf) to house these legacy drives.
Process:
Install the new //X chassis with the new DFMs.
Install the SAS Swing Shelf and populate it with the old SAS drives from the //M chassis.
Connect the SAS shelf to the //X controller (requires SAS connectivity).
The system sees the old data (external) and the new capacity (internal).
The system evacuates the data from the SAS shelf to the internal DFMs.
Once empty, the SAS shelf is removed.
A "DFM Swing Shelf" (Option A) would not help read the old SAS drives.
NEW QUESTION # 96
When accessing the FlashArray GUI, which management IP address is recommended for use?
- A. Virtual management IP
- B. CT0 management IP
- C. CT1 management IP
Answer: A
Explanation:
FlashArray controllers operate in an Active/Active high-availability cluster. Each controller (CT0 and CT1) has its own physical IP address for hardware-level management. However, Purity configures a Virtual IP (VIP) that floats between the two controllers.
The Virtual management IP is the recommended address for all administrative access, including the GUI, CLI, and API integrations. Using the VIP ensures High Availability (HA) for management sessions. If an Implementation Engineer were to log in directly to CT0's IP and CT0 subsequently rebooted (e.g., during an NDU or failure), the management session would be disconnected.
By contrast, the VIP automatically fails over to the surviving controller (CT1) in the event of a disruption, allowing the management session (and the GUI) to remain accessible. This abstraction layer simplifies administration, as the user does not need to know which controller is currently "primary" for management tasks. Direct controller IPs are typically reserved for specific hardware troubleshooting steps where accessing a specific node is required.

NEW QUESTION # 97
What is the maximum number of DirectFlash Shelves supported for FlashArray//XL?
- A. 0
- B. 1
- C. 2
Answer: B
Explanation:
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.
NEW QUESTION # 98
By default, which network interface does FA File use to resolve and reach domain controllers?
- A. management
- B. vif
- C. replication
- D. filevip
Answer: A
Explanation:
When deploying File Services (often referred to as FA File) on a unified Pure Storage FlashArray, the system must integrate with the customer's existing identity management infrastructure, most commonly Active Directory (AD). Joining the AD domain allows the array to authenticate users seamlessly for SMB and NFS file shares.
During the configuration of FA File, the Implementation Engineer creates a dedicated Virtual Network Interface (VIF), which handles all the high-throughput, frontend client data traffic (the file reads and writes).
However, control plane traffic behaves differently.
According to the official Pure Storage File Server Creation Wizard documentation, by default, FlashArray uses the management Ethernet port (management) for DNS communication and reaching domain controllers. The Purity operating system inherently routes LDAP queries, Kerberos authentication handshakes, and DNS hostname resolutions out of eth0 or eth1.
If the customer's network architecture is heavily segmented-meaning the management subnet is completely isolated and cannot route traffic to the Active Directory subnet-the Implementation Engineer must explicitly override this default behavior in the File Services configuration wizard by selecting the newly created File VIF as the "Source Network Interface" for DNS/AD traffic. Otherwise, the default remains the management interface.
NEW QUESTION # 99
What command will view NVRAM install and update status?
- A. purearray list
- B. purehw list --all
- C. puredrive list
Answer: B
Explanation:
The command purehw list --all is the correct CLI instruction to view the comprehensive status of all hardware components, including the NVRAM modules.
Command Scope: While purehw list provides a general hardware summary, the --all flag (or specifying --type nvram) ensures that granular details about the NVRAM modules-such as their presence, health status, and firmware/update status-are displayed.
NVRAM Context: In FlashArray models that utilize dedicated NVRAM modules (like the FA-400, //M, or specific //X configurations), these components are critical for write acknowledgement. During an upgrade or installation, verification that these modules are "healthy" and "idle" (not destaging) is mandatory.
Incorrect Options:
purearray list (Option A) displays high-level array attributes like the array name, ID, and overall OS version, but not component-level hardware status.
puredrive list (Option B) is specifically for managing the storage media (SSDs/DirectFlash Modules) and does not report on the non-volatile RAM cache modules housed in the controller or chassis.
NEW QUESTION # 100
The Customer's Implementation Workbook specifies that the SMTP reply is "outlook.microsoft.com:587". What correction should be made for array initialization to be successful?
- A. Provide username and password.
- B. Prefix the URL with "https://".
- C. Remove the port number.
Answer: C
Explanation:
For SMTP settings during array initialization, the host should be specified without the port number; including ":587" can cause connection issues and prevent successful initialization.
NEW QUESTION # 101
A client needs to upgrade Purity on their FlashArray, but is unable to wait for an available upgrade date from support.
What action should the customer take?
- A. Log into the Purity CLI, download the latest Purity version, and run the pureinstall command on each controller.
- B. Go through the Self-Service upgrade portal on Pure1 Manage and upgrade to the latest Purity version.
- C. Open a ticket with support, download the latest Purity version, copy to a USB flash drive, and run the pureinstall command on each controller.
Answer: B
Explanation:
Customers can independently upgrade Purity using the Self-Service upgrade portal on Pure1 Manage, enabling them to proceed without waiting for support scheduling.
NEW QUESTION # 102
FlashArray//C and //E models use which flash storage architecture, identifiable by gray tabs on the DirectFlash Module carriers?
- A. QLC flash
- B. TLC Flash
- C. SLC Flash
Answer: A
Explanation:
Pure Storage differentiates its product lines based on the type of NAND flash used, optimizing for either performance or capacity/cost.
* FlashArray//X uses TLC (Triple-Level Cell) flash for high performance and endurance. These modules typically have orange tabs.
* FlashArray//C and FlashArray//E are designed for high-capacity, capacity-optimized workloads.
They utilize QLC (Quad-Level Cell) flash.
QLC flash stores 4 bits per cell, offering higher density at a lower cost per terabyte, but with different endurance characteristics managed by the DirectFlash software. To help engineers and customers physically distinguish these modules, QLC DirectFlash Modules feature gray release tabs on the carrier. Identifying these tabs confirms that the correct media type is being installed into the capacity-oriented //C or //E chassis.

NEW QUESTION # 103
During a FlashArray installation, when should the Implementation Engineer run pureinstall on a controller?
- A. After confirming no hosts are connected to the controller.
- B. Immediately after completing the data migration phase.
- C. Prior to initializing/configuring the controller.
- D. After puresetup has been run with initial configuration set.
Answer: C
Explanation:
The pureinstall command is a low-level Purity operating system utility used strictly by Implementation Engineers and Pure Storage Support to install or upgrade the Purity//FA image on a controller's boot drive before the array is logically initialized.
When an Implementation Engineer unpacks a new FlashArray, the controllers may ship with a factory default version of Purity. If the customer's deployment requires a specific target version of Purity//FA (e.g., to match a fleet standard or enable a new feature), the engineer must boot into the controller via the local KVM/Serial connection and log in as the puresetup user. From here, they mount a USB drive containing the .ppkg firmware file and execute pureinstall purity- < version > .ppkg.
This process writes the new Purity operating system to the alternate boot partition. After executing pureinstall and rebooting the controller to boot from the new partition, the engineer then runs the puresetup newarray command (or puresetup secondary on the peer controller) to logically initialize the array, assign management IP addresses, and set the array name. Therefore, pureinstall must always be run prior to initialization.
NEW QUESTION # 104
Before starting the HWNDU, the Implementation Engineer discovers that DirectFlash Shelf SH9 is incorrectly cabled to CT0.
What should the Implementation Engineer do?
- A. Disconnect the shelf immediately to prevent data corruption.
- B. Fix the cabling during the CT0 replacement.
- C. Reschedule the HWNDU until a plan to fix the cabling is ready.
- D. Proceed with the HWNDU and fix the cable after the upgrade.
Answer: B
Explanation:
During the preparatory phases of a FlashArray Hardware Non-Disruptive Upgrade (HWNDU), validating physical connectivity is a strict prerequisite. If an Implementation Engineer discovers that a DirectFlash Shelf (like SH9) is incorrectly cabled to CT0, the safest and most efficient remediation is to correct the cabling precisely during the physical replacement of that specific controller.
Option A (proceeding and fixing it after) is perilous because leaving the improper cabling in place could compromise backend redundancy when the partner controller assumes the full I/O load, potentially leading to a multi-pathing failure or data unavailability event during the NDU. Option B (rescheduling the entire upgrade) is an unnecessary overreaction that wastes time and resources, as the upgrade procedure itself provides the perfect window for correction.
When the Implementation Engineer initiates the failover and successfully takes CT0 offline to swap the hardware, all active I/O is safely routed through CT1. Because CT0 is completely powered down and physically isolated from the data path at this stage, the engineer can safely disconnect the miswired SAS or NVMe-oF cables and re-cable them correctly into the new CT0 hardware according to the official Pure Storage cabling matrix. This method ensures maximum redundancy is restored the moment the new controller boots, seamlessly resolving the issue without introducing any additional maintenance windows or risks.
NEW QUESTION # 105
An Implementation Engineer is performing a hardware NDU from a fully populated FlashArray//X90R3 to a FlashArray//XL that already contains 20 DFM-Ds. The drive transfer is complete, and the //XL is still in SPM (Shelf Mode). What is the next step the Implementation Engineer should take to continue the upgrade?
- A. Evacuate and remove each DMM one-by-one then set aside.
- B. Hot swap and move each DMM into any open //XL slot.
- C. Evacuate DMM's as a datapack then install into any slot in //XL.
Answer: C
Explanation:
When upgrading from a FlashArray//X to a FlashArray//XL, the hardware migration often involves handling DirectMemory Modules (DMMs) differently than standard data drives. DMMs are high-performance cache modules that reside in the controller chassis.
In this specific scenario-migrating a fully populated //X90R3 to an //XL that already has its own set of DirectFlash Modules (DFM-Ds)-the DMMs from the old chassis need to be moved to the new chassis to preserve their cache function or be properly decommissioned.
The correct procedure is to Evacuate DMMs as a datapack then install into any slot in //XL.
DMMs cannot be simply "hot-swapped" randomly while the system is live in a way that disrupts the cache map.
They must be logically grouped and evacuated (conceptually "vacated" of active data) so they can be safely removed from the old chassis.
Once removed, they can be installed into the new //XL chassis. The //XL architecture supports DMMs in specific slots, and Purity will detect and re-incorporate them into the cache pool.
This ensures that the expensive SCM (Storage Class Memory) hardware is reused in the new system without causing data integrity issues during the transition.
