1Which command lists the hardware components and their health state on a FlashBlade chassis?
A.purehw list
B.puredrive list
C.puresys hardware
D.purefb status
Explanation: purehw list is the Purity//FB CLI command that enumerates hardware components — blades, fan modules, power supplies, XFM (External Fabric Module), and DirectFlash modules — along with their state (healthy, not_present, unhealthy). Support engineers use it as the first triage step when investigating a hardware alert.
2A FlashBlade//S chassis shows one blade with a solid amber status LED. Which interpretation is correct?
A.The blade has failed and is offline
B.The blade requires service attention but may still be online
C.The blade is being identified for hot-swap
D.Firmware is being upgraded on that blade
Explanation: On FlashBlade//S, a solid amber blade LED indicates a fault condition that requires service attention; the blade can still be online and serving I/O while degraded. A blinking amber LED is used for the locator/identify function. Support engineers should correlate the LED with purehw list and pureservice list output before pulling a blade.
3What does XFM stand for in FlashBlade//S architecture?
A.External Flash Module
B.Extended File Manager
C.External Fabric Module
D.Extended Flash Memory
Explanation: XFM is the External Fabric Module on FlashBlade//S. XFMs sit in the rear of the chassis and provide the high-speed Ethernet fabric that interconnects blades within and across chassis. A FlashBlade//S deployment normally has redundant XFMs per chassis; loss of one XFM is non-disruptive but degrades fabric capacity.
4A field engineer is preparing to replace a faulty DirectFlash Module (DFM) in a FlashBlade//S blade. What is the correct guidance regarding DFM slot population?
A.DFMs may be installed in any free slot on the blade
B.DFMs must be installed sequentially starting at slot 1, and every blade in a chassis should have the same DFM count
C.All DFMs in a blade must be the same model but slot order does not matter
D.DFMs are pre-allocated to specific blades and cannot be moved between blades
Explanation: Per Pure Storage installation guidance, DFMs are populated sequentially (slots 1, 2, 3, 4) and every blade should carry the same number of DFMs to keep capacity balanced for erasure coding. Mixed DFM counts across blades trigger validation warnings and reduce usable capacity.
5Which Purity//FB CLI command shows the open service tickets and Pure Support diagnostic state for the array?
A.puresupport list
B.pureservice list
C.purealert list
D.puremessage list
Explanation: pureservice list shows the support service tasks Purity//FB has open against components — for example a pending DFM swap, a blade replacement, or a chassis cable fault. It is the canonical command to confirm whether a hardware fault has been registered with Pure Support.
6Which two FlashBlade chassis form factors does Pure Storage currently sell as scale-out platforms?
A.FlashBlade//C and FlashBlade//R
B.FlashBlade//S and FlashBlade//E
C.FlashBlade//M and FlashBlade//X
D.FlashBlade//N and FlashBlade//A
Explanation: The current FlashBlade scale-out family is FlashBlade//S (performance, S100/S200/S500/S550 generations) and FlashBlade//E (capacity-optimized for unstructured data and backup). FlashBlade//S uses XFM-based external fabric; FlashBlade//E uses a similar modular blade design tuned for cost-per-TB.
7On a FlashBlade//S chassis, what is the supported way to physically remove a single blade for replacement?
A.Power off the entire chassis, then remove the blade
B.Use the Purity//FB GUI to evacuate the blade, wait for the LED to indicate safe-to-remove, then unlatch and pull the blade
C.Pull the blade immediately — Purity//FB tolerates hot-removal at any time
D.Remove both XFMs first to isolate the fabric, then pull the blade
Explanation: FlashBlade is hot-swappable per blade, but Pure's documented procedure is to use the Purity//FB GUI or CLI to mark the blade for removal so the system can drain in-flight work and signal a safe-to-remove state via the blade LED. Pulling without that handshake risks transient errors; pulling XFMs is never required.
8Which Purity//FB command displays the array-level identity, software version, and overall health summary?
A.purearray list
B.puresys info
C.purefb show
D.pureconfig list
Explanation: purearray list reports the array name, ID, Purity//FB version, and overall status. It is the first command an engineer runs when joining a remote support session because it confirms which array and code line they are working on before deeper triage.
9Two chassis in a FlashBlade//S deployment lose all inter-chassis connectivity. Which component is the root suspect for a fabric-level outage between chassis?
A.DirectFlash Modules in chassis 1
B.External Fabric Modules (XFMs) and their inter-chassis links
C.The boot drive on the management blade
D.The chassis power supply units
Explanation: The XFMs and the cabling between them carry the high-speed inter-chassis Ethernet fabric. If both chassis show purehw errors on XFM ports or links, the fabric path is the primary suspect. Support engineers verify XFM status, link state, and inter-chassis cabling before suspecting blades or DFMs.
10A customer asks whether removing a single power supply unit (PSU) from a FlashBlade//S chassis is disruptive. What is the correct answer?
A.Yes — the chassis powers off
B.No — chassis PSUs are redundant; pulling one degrades redundancy but does not stop service
C.Only if there are more than four blades installed
D.Only if the firmware is older than 4.0
Explanation: FlashBlade//S chassis PSUs are deployed in a redundant configuration so that the loss of one PSU is non-disruptive. Purity//FB raises an alert and the chassis runs on remaining PSUs until the failed unit is replaced. Sustained operation with reduced redundancy is supported but should be remediated quickly.

Pure FBSS Study Tips from Top Performers

1Memorize the FBSS CLI verb-by-object grid: purearray, purehw, pureservice, purefs (with snapshot/export/smbshare subtrees), pureobjbucket, pureobjuser, purevip, puread, pureldap, pureadmin
2Drill SafeMode in detail — what it protects, why a local admin cannot eradicate immutable snapshots before the timer, and the out-of-band Pure Support verification path required for early eradication
3Practice the file vs object replication setup: purearray connect for the peer link, replica links per filesystem or bucket, and the troubleshooting pattern when a link goes paused or idle
4Study NFS security flavors (sec=sys, krb5, krb5i, krb5p), root_squash vs no_root_squash, and the multi-protocol identity mapping pattern when SMB and NFS share a filesystem
5Build a personal triage checklist for client-side issues so you reach for client logs, DNS, and reachability to the data VIP before suspecting the array
