2026 Pure Certified Flash Array
Implementation Specialist Practice Exam
2026
DESCRIPTION
The Pure Certified FlashArray Implementation Specialist practice exam is a professional-
level assessment designed to validate a candidate's hands-on expertise in the end-to-end
deployment and maintenance of Pure Storage Flash Array solutions.
Core Exam Domains
The exam focuses on four primary stages of the implementation lifecycle:
Pre-Installation & Planning: Evaluating site readiness, environmental
requirements, hardware compatibility, and verifying documentation.
Installation: Executing physical setup, including racking, cabling (Fibre
Channel/iSCSI), and initial network and system configurations.
Upgrades: Managing firmware (Purity) and hardware upgrades, capacity additions,
and non-disruptive upgrade (NDU) procedures.
Post-Installation & Maintenance: Performing health checks, troubleshooting
connectivity, volume provisioning, and confirming the deployment meets
operational expectations.
Exam Format & Details
Question Types: Approximately 60 scored multiple-choice and scenario-based
questions, plus up to 15-20 unscored pilot questions.
Duration: 120 minutes.
Target Audience: Implementation engineers and support specialists with 12–24
months of relevant experience.
Key Topics: Purity CLI commands, Pure1 monitoring, host integration (VMware,
Windows, Linux), and ActiveCluster configuration

,Pure Storage FlashArray Implementation Specialist (PCFAIS)
Master Set
Domain: Installation, Configuration, and Optimization
1. During the physical installation of a FlashArray //X, which component provides
the high-availability "heartbeat" and data synchronization between the two
controllers?
A) External 10GbE Twinax cables
B) External SAS cables
C) The passive midplane
D) A dedicated heartbeat serial cable
Answer: C
Rationale: Pure Storage utilizes a stateless controller architecture. All data
synchronization, non-volatile RAM (NVRAM) mirroring, and management heartbeats
occur across a high-speed, passive midplane within the chassis. This eliminates "cable
clutter" and removes external points of failure.
2. What is the recommended vertical placement for a FlashArray base chassis
and its expansion shelves in a standard 42U rack?
A) Base chassis at the top of the rack to allow for heat dissipation.
B) Base chassis at the bottom (or lowest available U) to maintain stability.
C) Expansion shelves at the bottom, base chassis in the middle.
D) It does not matter as long as they are adjacent.
Answer: B
Rationale: Safety and rack stability are paramount. Always install the heaviest
components (the base chassis) at the lowest possible point in the rack to maintain a low
center of gravity. Expansion shelves should be installed directly above the base chassis
to optimize SAS cabling lengths.
3. You are initializing a new array via the CLI. Which command initiates the
interactive setup wizard for management and secondary network configuration?
A) pureconfig setup
B) puresetup
C) purenetwork init
2026 Question And ANSWER Latest Update
,D) config network
Answer: B
Rationale: The puresetup command is the primary interactive wizard used in the CLI
to configure the management network, secondary network, DNS, and NTP settings
during initial array setup.
4. When configuring Fibre Channel (FC) zoning for a VMware ESXi host, which
zoning topology is the Pure Storage "Best Practice"?
A) One zone per fabric containing all host HBAs and all array target ports.
B) Single-initiator, single-target (or single-port).
C) Multi-initiator, multi-target.
D) Zoning is not required for FC.
Answer: B
Rationale: Pure Storage recommends "Single-Initiator, Single-Target" (SI-ST) zoning.
This minimizes Registered State Change Notifications (RSCNs) and ensures that if a
port flutters, only that specific path is affected, preventing I/O timeouts across other
paths.
5. What is the minimum number of SAS cables required to connect one expansion
shelf to a FlashArray base chassis to maintain N+1 redundancy?
A) 1
B) 2
C) 4
D) 8
Answer: C
Rationale: To maintain full redundancy, each controller (CT0 and CT1) must have two
independent paths to the expansion shelf. This requires 4 SAS cables total (2 per
controller) using the "top-down/bottom-up" cabling pattern.
6. A customer wants to use "ActiveCluster" for business continuity. What is the
maximum supported Round Trip Time (RTT) latency between the two sites?
A) 2ms
B) 5ms
C) 11ms
D) 25ms
Answer: C
Rationale: ActiveCluster provides synchronous replication. Because every "Write" must
be acknowledged by both arrays before the host receives a success signal, Pure
supports up to 11ms RTT to ensure application performance remains acceptable.
2026 Question And ANSWER Latest Update
, 7. In Purity//FA, what is the primary function of a "Host Group"?
A) To manage the physical power of multiple arrays.
B) To group multiple hosts together so they can share access to the same volumes
(Cluster).
C) To limit the bandwidth of a single host.
D) To organize volumes by department.
Answer: B
Rationale: Host Groups simplify management for clustered environments (like VMware
or Windows Clusters). Mapping a volume to a Host Group ensures all nodes in the
cluster see the same LUN ID for shared volumes.
8. Which Purity feature allows for a "point-in-time" copy of a volume that is
space-efficient and does not impact performance?
A) Mirroring
B) ActiveDR
C) Snapshots
D) Volume Clones
Answer: C
Rationale: Pure snapshots are metadata-based. They do not copy data; they simply
freeze the current state. They consume zero additional space until data on the original
volume changes and have zero performance overhead.
9. When configuring iSCSI, what is the purpose of "Jumbo Frames" (MTU 9000)?
A) To encrypt the data.
B) To allow more data to be sent in a single Ethernet frame, reducing CPU overhead.
C) To prevent the array from overheating.
D) It is only used for management traffic.
Answer: B
Rationale: Standard frames are 1500 bytes. By increasing this to 9000 (Jumbo), the
ratio of "payload" to "header" improves, reducing the number of interrupts the host CPU
must process, leading to higher throughput.
10. You are using the "Pure1" mobile app during an implementation. What is the
primary benefit for the specialist?
A) It can physically power on the array.
B) It allows for remote initialization and health monitoring.
C) It replaces the need for SAS cables.
D) it can be used as a serial console.
Answer: B
