Questions for the FLASHARRAY IMPLEMENTATION SPECIALIST were updated on : Nov 21 ,2025
What is the required PSU wattage for a FlashArray// X70R2/R3 or X90R2/R3 array?
C
Explanation:
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.
What is the rack unit height of a FlashArray//XL?
B
Explanation:
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.
An Implementation Engineer performing an inventory of hardware for an NDU from an
FlashArray//X70R2 to an FlashArray //X90R3 and discovers c complete FlashArray//X90R3 was
shipped in place of an NDU kit. What is the minimum hardware the Implementation Engineer should
use from this array to complete the NDU?
A
Explanation:
For an NDU from FlashArray//X70R2 to //X90R3, the minimum required hardware from the shipped
array is the controllers, which are swapped into the existing chassis and power infrastructure.
After upgrading Purity during a new installation, which command should an Implementation
Engineer run to determine what version of Purity will be loaded at the next boot of the FlashArray?
C
Explanation:
The pureboot list command shows the versions of Purity installed and indicates which version will be
loaded on the next system boot.
In a situation where iSCSI cards need to be re-used during a controller upgrade, which is a valid
transfer path?
A
Explanation:
iSCSI cards can be reused when upgrading from XR2 to XR3 controllers, supporting hardware
continuity within this upgrade path.
What is the maximum number of SAS shelves supported for FlashArray//XL?
B
Explanation:
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.
An Implementation Engineer is setting up a customer environment and has specified a number of
NTP servers.
Which command should the Implementation Engineer run to list the NTP servers that have been
configured?
B
Explanation:
The command purenetwork list --ntpserver displays the configured NTP servers on the FlashArray
network settings.
When installing the first DirectFlash Shelf on a FlashArray//XR2/3, what mezzanine ports are used on
the controllers?
B
Explanation:
When installing the first DirectFlash Shelf on a FlashArray//XR2/3, mezzanine ports ETH6 and ETH9
on the controllers are used for connectivity.
A dark site customer requests an evacuation of SH01 on a FlashArray/M50. What is an appropriate
next step?
B
Explanation:
Before evacuating a shelf on a FlashArray/M50, usable capacity should be below 80% to provide
enough free space for safe data migration.
A customer wants to expand the capacity of their FlashArray//X10 from 5/5 to 11/11. Which is the
correct action to take?
C
Explanation:
To expand capacity from 5/5 to 11/11 packs, a swing shelf with temporary loan capacity is needed to
safely evacuate data during the upgrade without risking data availability.
At the completion of an upgrade, which command is used to send phonehome logs?
B
Explanation:
The command purearray phonehome --send-logs is used to send all Phonehome logs to support
upon completion of an upgrade.
An Implementation Engineer is assigned to install a 4X Module 9.1 TB Conversation Kit in a Flash
Array Chassis. Why are there only four Direct Flash Modules?
A
Explanation:
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.
A customer has ordered several FlashArrays and wants to have ActiveCluster configured. What is the
maximum quantity of arrays supported with ActiveCluster?
A
Explanation:
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.
When should a FlashArray support case be opened?
C
Explanation:
Opening a support case before starting the installation ensures timely assistance and coordination
with support throughout the deployment process.
What command can be used to identify interface status?
B
Explanation:
The command purenetwork list --all provides a comprehensive view of all network interfaces and
their status on the FlashArray.
