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 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

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 Rationale: Pure1 provides "Management as a Service." It allows the specialist to register the array, monitor data reduction rates, and receive proactive alerts if a component is misconfigured during the initial setup. 11. What is the specific role of the "Quorum Witness" in an ActiveCluster implementation? A) To store the primary data. B) To act as a "tie-breaker" in a split-brain scenario to determine which array stays online. C) To increase the IOPS of the cluster. D) To manage the local snapshots. Answer: B Rationale: In a split-brain scenario where the link between sites fails, the Witness (a SaaS instance in Pure1) determines which array wins the "lock" and stays online, preventing data inconsistency. 12. When cabling a FlashArray //X for iSCSI, which ports are used for "Data" traffic by default? A) The onboard 1GbE ports. B) High-speed Mezzanine (Eth) or I/O Slot ports. C) The Serial console port. D) The SAS expansion ports. Answer: B Rationale: Onboard 1GbE ports are strictly for Management. High-performance data traffic (iSCSI/NVMe-oF) requires the 10/25/100GbE ports located in the I/O slots or the dedicated Mezzanine cards.

13. A specialist needs to verify if the environmental conditions (Temp/Power) are within spec. Which CLI command provides hardware-level health data? A) purehw list B) purearray monitor C) purecheck D) puresupport list Answer: A Rationale: purehw list provides a comprehensive view of every physical component—fans, power supplies, NVRAM, and sensors. It shows the operational status (OK/Failing) of all hardware. 14. What is the primary purpose of the purecheck tool? A) To check the customer's credit score. B) To run a health audit against Best Practices for cabling and configuration. C) To benchmark the IOPS of the array. D) To update the Purity firmware. Answer: B Rationale: purecheck is a script run by specialists to validate the environment, redundant cabling, and configuration against best practices before handing the system to the customer. 15. When configuring "ActiveDR", what does the term "Pod" refer to? A) A physical container for the array. B) A logical management container that groups volumes and settings for replication. C) A specialized SSD. D) A type of network cable. Answer: B Rationale: Pods are the management unit for ActiveCluster and ActiveDR. Volumes placed in a Pod are managed as a single entity, ensuring consistency across replicated sites. 16. Which of the following is a requirement for "SafeMode" snapshots? A) They must be deleted manually every 24 hours. B) They are protected from being deleted by any user (including admins) for a set period. C) They require a separate license. D) They only work on Fibre Channel. Answer: B Rationale: SafeMode is a ransomware protection feature. Once enabled, snapshots

Answer: B Rationale: Pure1 Cloud Connect (Phone Home) allows the array to send telemetry and heartbeats to Pure Support every 30 seconds, allowing for proactive support and automated case opening.

21. When initializing an array, which Purity//FA version should be used? A) The oldest version available for stability. B) The specific version recommended by Pure Support or the latest "Target" release. C) Any version, as the array updates automatically. D) Only version 1.0. Answer: B Rationale: Specialists should always install the "Target" release, which is the version Pure has vetted as the most stable for production across the global install base. 22. What is the maximum number of expansion shelves supported on a FlashArray //X90? A) 1 B) 2 C) 4 D) Dependent on the specific model and Purity version. Answer: D Rationale: Shelf support varies by chassis generation and model. For example, a //X90R2 might support more shelves than a //X10. Always consult the Pure Storage "Quick Reference Guide" for specific model maximums. 23. When cabling for NVMe-oF (RoCE), what is a mandatory network requirement? A) 1GbE speeds. B) Data Center Bridging (DCB) and Priority Flow Control (PFC). C) Standard unmanaged switches. D) Wi-Fi 6. Answer: B Rationale: NVMe-oF over RoCE (RDMA over Converged Ethernet) is lossless. It requires DCB and PFC on the switches to prevent packet loss, which would otherwise crash the high-speed storage session. 24. In the Purity UI, a host is showing "Redundant" connectivity but "Partial" multipathing. What is the most likely cause? A) One controller is powered off. B) The host has only one HBA logged in to both controllers.

C) The host has two HBAs but only one is zoned to the array. D) The array is full. Answer: C Rationale: "Partial" connectivity usually implies the host can see the array, but it is not utilizing all the redundant paths required for a high-availability best-practice configuration.

25. What is the function of the "DirectFlash" software? A) It manages the cooling fans. B) It manages flash at the system level instead of using a traditional SSD flash translation layer (FTL). C) It translates iSCSI to Fibre Channel. D) It encrypts management traffic. Answer: B Rationale: DirectFlash software speaks directly to the raw flash bits. This eliminates the "garbage collection" delays found in standard SSDs, resulting in more consistent, low- latency performance. 26. How many NVRAM modules are found in a standard FlashArray //X base chassis? A) 1 B) 2 C) 4 D) 10 Answer: B Rationale: There are two NVRAM modules in the front of the chassis. They are used to acknowledge writes instantly (journaling) before the data is de-staged to the flash modules. 27. A specialist is configuring "ActiveDR". Which state must the replica Pod be in to allow the host to write to it? A) Promoted B) Demoted C) Synchronizing D) Paused Answer: A Rationale: In ActiveDR, the source Pod is "Promoted" (Read/Write). The target Pod is "Demoted" (Read-Only). To perform a failover or test, the target Pod must be "Promoted" to allow host writes.

32. Which tool is used to monitor real-time performance (IOPS/Latency) in the CLI? A) puremonitor B) purevol monitor C) purearray monitor D) pureperf Answer: C Rationale: purearray monitor provides a scrolling real-time view of the array's total performance metrics. 33. When cabling a new expansion shelf, what is the "Rule of 2"? A) 2 people must lift it. B) Use 2 SAS cables per controller for a total of 4 per shelf. C) It takes 2 minutes to boot. D) Only 2 shelves are allowed. Answer: B Rationale: This ensures redundant paths from CT0 and CT1 to both I/O modules on the expansion shelf. 34. A customer wants to move a volume from one array to another without downtime. Which feature is used? A) ActiveDR B) ActiveCluster C) FlashMove D) Snapshot shipping Answer: B Rationale: By using ActiveCluster to stretch a volume across two arrays and then performing a "Storage Motion" at the host layer, data can be migrated with zero downtime. 35. What is the default password for the pureadmin account upon initialization? A) admin B) purestorage C) pureadmin D) There is no default; it is set during puresetup. Answer: B Rationale: The factory default password is purestorage , but puresetup forces the specialist to change it immediately for security.

36. In a Fibre Channel environment, what is "Fan-in"? A) Cooling the HBAs. B) Mapping multiple hosts to a single array port. C) Mapping one host to multiple array ports. D) Connecting two switches together. Answer: B Rationale: Fan-in allows many hosts to share the high bandwidth of a single FlashArray FC port, maximizing port utilization. 37. Which Purity feature provides asynchronous replication with a low RPO? A) ActiveCluster B) ActiveDR C) Continuous Snapshots D) Periodic Replication Answer: B Rationale: ActiveDR provides near-continuous asynchronous replication with RPOs typically measured in seconds, ideal for DR across long distances. 38. What is the purpose of the "Directory Service" configuration? A) To list the array in a phone book. B) To integrate with Active Directory or LDAP for administrative authentication. C) To manage the file folders on the array. D) To organize the SAS cables. Answer: B Rationale: This allows customers to log in to the Purity UI using their existing corporate credentials. 39.

What is the maximum number of snapshots supported per volume? A) 1, B) 5,

B) Only iSCSI C) HTTP D) FTP Answer: A Rationale: FlashArray is a unified storage platform that supports both Block (FC/iSCSI) and File (NFS/SMB) protocols.

45. What is the benefit of "DirectFlash Fabric"? A) It uses cheaper cables. B) It enables NVMe-over-Fabrics (NVMe-oF) for end-to-end NVMe performance between host and flash. C) It makes the LED lights brighter. D) It only works with SATA drives. Answer: B Rationale: By removing the SCSI translation layer and using NVMe-oF, latency is reduced and throughput is increased compared to traditional iSCSI or FC. 46. How many "Management" IP addresses are typically configured on a FlashArray? A) 1 /B) 3 (1 Virtual IP, 2 Physical Controller IPs) C) 5 D) 0 Answer: B Rationale: A best practice setup uses one VIP (Virtual IP) for the UI/CLI access and one static IP for each controller's management port for individual maintenance. 47. A specialist is configuring "Replication". What is the maximum number of target arrays a single source array can replicate to (Fan-out)? A) 2 B) 4 C) 10 D) 24 Answer: D Rationale: Purity supports a fan-out of 1:24, allowing one array to send snapshots to up to 24 different target arrays. 48.
