Sample Pure Storage FBIS Practice Questions

Try these sample questions to test your Pure Storage FBIS exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the rack height of a single FlashBlade//S chassis?
A.3U
B.4U
C.5U
D.6U
Explanation: A FlashBlade//S chassis is 5U tall and holds a minimum of 7 and a maximum of 10 blades. The dimensions are approximately 8.59" x 17.43" x 32.00" and the chassis must be mounted on rails that support its full depth and weight when fully populated with DFMs.
2What is the minimum and maximum number of blades supported in a single FlashBlade//S chassis?
A.5 minimum, 15 maximum
B.7 minimum, 10 maximum
C.4 minimum, 8 maximum
D.10 minimum, 10 maximum
Explanation: FlashBlade//S chassis ship with a minimum of 7 blades and scale to a maximum of 10 blades per 5U chassis. All blades in a chassis must be the same model (S100, S200, or S500) and must have the same number and capacity of DirectFlash Modules.
3How many DirectFlash Modules (DFMs) can a single FlashBlade//S blade hold?
A.1
B.2
C.Up to 4
D.Up to 8
Explanation: Each FlashBlade//S blade holds up to 4 DirectFlash Modules. At least one DFM is required to bring a blade online, and Pure recommends populating identical DFM count and capacity across blades in the same chassis to keep capacity layout balanced.
4What is the rack height of an XFM (External Fabric Module) used in FlashBlade//S multi-chassis configurations?
A.1U
B.2U
C.5U
D.XFMs do not occupy U space
Explanation: Each XFM-8400 or EFM-3200e External Fabric Module is 1U high, with dimensions roughly 1.7" x 17.26" x 25.89". A multi-chassis FlashBlade//S deployment requires exactly two XFMs for redundancy, occupying 2U of additional rack space outside the chassis themselves.
5How many XFMs are required for a FlashBlade//S multi-chassis (scale-out) configuration?
A.1
B.2
C.4
D.One per chassis
Explanation: All FlashBlade//S multi-chassis configurations require exactly 2 XFMs (XFM-8400 or EFM-3200e), regardless of how many chassis are connected (1 to 5 per the multi-chassis install guide). The two XFMs provide redundant external fabric paths between blades and the customer network.
6In a FlashBlade//S single-chassis configuration, what carries data between blades and the client network?
A.External XFMs only
B.Two redundant Fabric I/O Modules (FIOMs) integrated into the chassis
C.An external Cisco Nexus 9000
D.Each blade's onboard 1G management port
Explanation: In a single-chassis FlashBlade//S, two Fabric I/O Modules (FIOMs) at the rear of the chassis interconnect blades and present external uplink ports for client traffic. XFMs are only used in multi-chassis (scale-out) configurations; the FIOMs handle data-plane traffic standalone in a single chassis.
7What is the maximum number of FlashBlade//S chassis supported in a single multi-chassis system, per the official Pure Storage Multi-Chassis Installation Guide?
A.3
B.5
C.10
D.75
Explanation: The current FlashBlade//S Multi-Chassis Installation Guide caps a single multi-chassis system at 5 chassis (with a minimum of 1) using two XFMs. The 10-chassis figure on the //S datasheet refers to scale-out architecture roadmap; the field-installable maximum tied to the published install runbook is 5.
8What is the maximum number of blades in a 5-chassis FlashBlade//S system?
A.35
B.50
C.75
D.150
Explanation: With a maximum of 10 blades per chassis and 5 chassis per multi-chassis system, the maximum blade count is 5 x 10 = 50 blades. Each blade holds up to 4 DFMs, giving a maximum of 200 DFMs in the system.
9What is the maximum number of DirectFlash Modules in a fully populated 5-chassis FlashBlade//S system?
A.50
B.100
C.200
D.500
Explanation: 5 chassis x 10 blades per chassis x 4 DFMs per blade = 200 DFMs maximum. The Multi-Chassis Installation Guide explicitly states a minimum of 7 (one chassis, one DFM per blade) and a maximum of 200 DFMs across the system.
10Which DirectFlash Module capacities are supported on FlashBlade//S200 and //S500 blades, per current Pure Storage datasheets?
A.8TB and 16TB
B.24TB, 48TB, and 75TB
C.37TB only
D.100TB and 150TB
Explanation: FlashBlade//S200 and //S500 blades support 24TB, 48TB, and 75TB DirectFlash Modules. The //S100 launched with 37TB DFMs (and later 18TB). Up to 4 DFMs per blade gives a maximum of up to 300TB raw per //S200/S500 blade with 75TB DFMs.

About the Pure Storage FBIS Exam

Pure Storage FBIS Study Tips from Top Performers

1Memorize the FlashBlade//S form factor: 5U chassis, 7 minimum and 10 maximum blades, up to 4 DFMs per blade, supported DFM sizes 24/48/75TB on //S200 and //S500 (37TB on //S100), and 2 XFMs required only in multi-chassis configurations
2Drill the multi-chassis cabling rule: connect chassis to both XFMs first but do NOT connect the customer (uplink) cables to the XFM-8400/EFM-3200e modules until Purity//FB has been upgraded; LACP is the only supported switch aggregation
3Lock in the Purity//FB upgrade flow: pre-checks, stage (copy + verify image to all blades), activate (rolling per-blade reboot maintaining quorum), post-checks; and remember 3.3.x and 4.1.x are bridgehead releases on the path to 4.5.x
4Practice the DFM conversion path 24TB to 48TB to 75TB on //S200 and //S500, including blade-by-blade evacuation, and remember //S200 and //S500 cannot be intermixed in a single chassis
5Walk through pre-install items the customer must deliver: 200-240 V PDUs with C13/C14 or C19/C20 receptacles, BTU/hr cooling headroom, two top-of-rack switches in MC-LAG/vPC, VLAN plan with jumbo MTU 9000, DNS forward/reverse, internal NTP, AD service account, and outbound HTTPS to Pure1 endpoints
6Be fluent in post-install validation: HEALTHY array state via purehw/pureblade list, capacity matches BOM (blades x DFM count x DFM size), DRR climbs as workloads land, NFS/SMB/S3 round-trips succeed, pure-fbsupport bundle is clean, fabric link counters stay zero across an observation window

Frequently Asked Questions

How is the Everpure FBIS exam delivered and how long is it?

FBIS is delivered through Pure Storage's Pure Academy / ExamStudio platform as an online-proctored exam and runs for 120 minutes. You answer 60 scored multiple-choice questions plus an average of 15 unscored pre-test items used by Pure Storage to evaluate future content, for a total of about 75 questions in the session.

How much does the FBIS exam cost?

The Everpure FBIS exam costs $300 USD per attempt, paid through Pure Academy / ExamStudio. Each retake also requires the standard $300 fee. Internal Everpure employees and certain partner programs may have access to vouchers; verify with your Pure Storage account team.

What does FBIS cover that the FlashBlade Storage Professional (FBSP) does not?

FBSP is a professional-tier FlashBlade exam focused on conceptual and administrative knowledge. FBIS is the implementation-specialist exam, focused on hands-on install, upgrade, expansion, conversion, and post-install validation tasks. FBIS heavily tests domain weights of 32% installation, 33% upgrades/conversions/expansions, 20% pre-installation, and 15% post-installation activities.

How long is an FBIS certification valid?

Pure Storage certifications, including FBIS, are valid for 3 years from the date of issue. To stay current you either re-pass the latest version of the exam or pass a successor implementation-specialist exam before your existing certification lapses.

What hands-on knowledge is most important for FBIS?

Spend the most time on: FlashBlade//S chassis form factor (5U, 7-10 blades, up to 4 DFMs per blade), single-chassis FIOM uplinks vs multi-chassis XFM-8400/EFM-3200e fabric, the documented multi-chassis cabling sequence (do not connect XFM uplinks until Purity//FB is upgraded), Purity//FB NDU stage/activate/bridgehead behavior, DFM conversions (24/48/75TB), blade evacuation, LACP design across two customer switches, and customer pre-install IP/VLAN/DNS/NTP planning.

Is hands-on FlashBlade access required to pass FBIS?

Pure Storage does not require hands-on access to register, but FBIS targets internal/partner implementation engineers and dark-site admins with root-level FlashBlade access. Candidates without lab time typically struggle with the operational nuances around NDU pre-checks, blade evacuation, and DFM conversion runbooks. Pair the Pure Academy FBIS Prep course with as much real or simulated install/upgrade time as possible.
