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

Adding the host itself to a protection group automatically includes all volumes connected to that host, ensuring comprehensive data protection without manual volume-by-volume assignment.

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.

Adding a DirectFlash Shelf with sufficient temporary extra capacity (63TB) allows data to be evacuated from the smaller 22TB packs during the swap, enabling consolidation withoutreducing array usage beforehand.

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.

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.

Mirrored Write statistics appear in the Purity GUI’s Analysis section when ActiveCluster is enabled, as it tracks synchronous replication activity between clusters.

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.

In the FlashArray//XR2 and //XR3 models, the 2-port InfiniBand card should be installed in PCIe slot 2 on controller CT1. This slot is designated for InfiniBand connectivity, ensuring optimal performance and compatibility during the upgrade process. Installing the card in the correct slot is crucial for maintaining proper system functionality and achieving the desired performance metrics.

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

FlashArray ActiveCluster is designed for synchronous replication between two FlashArray systems, enabling active-active configurations across two sites. This setup allows both arrays to serve I/O simultaneously, providing high availability and zero RPO (Recovery Point Objective). Each array in the ActiveCluster configuration maintains identical volume identities, ensuring seamless access for hosts regardless of the array they connect to. The configuration supports metro-area clustering, with a maximum round-trip latency of 11 milliseconds between arrays. Additionally, the Pure1 Cloud Mediator or an on-premises mediator is utilized to manage failover and prevent split-brain scenarios, eliminating the need for a third site or external gateway.

While ActiveCluster supports a two-site configuration, it does not support additional arrays within the same synchronous setup. For scenarios requiring protection across more than two sites, asynchronous replication solutions like ActiveDR™ can be employed. ActiveDR allows for asynchronous replication to a third site, providing broader disaster recovery capabilities.

Therefore, the maximum number of arrays supported in a single ActiveCluster configuration is two.

The FlashArray//XL supports up to two DirectFlash Shelves (DFS) for capacity expansion. This configuration allows for scalable storage solutions while maintaining optimal performance and efficiency. Each shelf can be connected to the array using appropriate interfaces, ensuring seamless integration and data flow. This setup is particularly beneficial for environments requiring high throughput and low latency, such as large-scale databases and enterprise applications.

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

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

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.

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

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.

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

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.

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.

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

FlashArray//XL models are designed with 9 PCIe slots per controller, providing ample connectivity options for various components. Slot 5 is specifically reserved for non-disruptive upgrade (NDU) procedures, ensuring that controller upgrades can be performed without impacting system availability. This slot allocation is part of the system's design to facilitate seamless upgrades and maintain operational continuity.

The FlashArray//X20R4 requires a minimum AC input voltage of 180V to operate. This ensures stable power delivery for the array's components.
