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
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
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.
18. What is the primary difference between a FlashArray //X and a FlashArray //C? A) //X uses SATA; //C uses NVMe. B) //X is for high-performance (TLC); //C is for capacity-optimized workloads (QLC). C) //X cannot do snapshots. D) //C does not support iSCSI. Answer: B Rationale: The //X series uses TLC DirectFlash for low-latency performance. The //C series uses QLC DirectFlash to provide NVMe speeds at a lower price point for capacity-heavy tier-2 workloads. 19. How does global "Data Reduction" impact the performance of a FlashArray? A) It slows down the array during peak hours. B) It has zero impact because it is handled by dedicated hardware offload engines. C) It requires the array to be rebooted weekly. D) It only works on large files. Answer: B Rationale: Data reduction (deduplication and compression) is "always-on" and handled by dedicated hardware engines, meaning there is zero performance or latency penalty for these savings. 20. A specialist is configuring "Alerts". What is the Pure-recommended method for sending alerts to Pure Support? A) Manual email exports once a month. B) Enabling "Phone Home" (Pure1 Cloud Connect). C) Setting up a physical fax line. D) Alerts are not sent to Pure; they are only local. 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.
D) 161 (SNMP)
Answer: B Rationale: The arrays communicate with the Pure1 Cloud Mediator via outbound HTTPS (port 443) to provide quorum services.
30. When replacing a failed controller, what is a critical step for the specialist? A) Reinstall Purity on the new controller from a USB drive. B) Simply insert the new controller; Purity is stateless and will sync from the active controller. C) Power off the entire array first. D) Change the IP address of the management port. Answer: B Rationale: Pure controllers are "stateless." All configuration and data are on the flash/midplane. When a new controller is inserted, it automatically boots the version of Purity running on the active peer. 31. What is the maximum number of volumes supported in a single FlashArray Pod? A) 500 B) 1, C) 5, D) 10, Answer: C Rationale: As of recent Purity 6.x releases, a single Pod can contain up to 5, volumes, allowing for massive scale-out replication groups. 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
42. When configuring a host on the array, what is the "Host Personas" setting used for? A) To change the color of the UI for that host. B) To adjust the array's behavior/responses to match specific OS requirements (e.g., AIX or Solaris). C) To name the host. D) To set the host's password. Answer: B Rationale: Most modern OSs (Windows/Linux/ESXi) use the "Default" persona, but legacy or specialized systems like AIX require a "Persona" change to ensure correct SCSI command handling. 43. What is "Eradication"? A) Deleting a volume instantly. B) The 24-hour waiting period before a "deleted" volume is permanently destroyed. C) Updating the firmware. D) Formatting a drive. Answer: B Rationale: When you delete a volume, it goes to a "Destroyed" state for 24 hours. Eradication is the final, permanent removal of that data. This acts as a safety net against accidental deletion. 44. Which protocol is supported for "File" services on FlashArray (via Purity//Run or File Services)? A) NFS and SMB 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. What is the CLI command to create a new volume of 500GB? A) purevol create --size 500G MyVol B) puresize MyVol 500G C) purevol new MyVol 500G D) config vol create 500G Answer: A Rationale: The purevol command set manages all volume-related tasks in the CLI. 49. Which Pure1 feature helps with capacity and performance planning? A) Pure1 Manage B) Pure1 Analyze (Meta) C) Pure1 Support D) Pure1 Connect Answer: B Rationale: Pure1 Analyze uses AI (Meta) to predict when an array will run out of capacity or performance based on historical trends.
Answer: A Rationale: pureport list displays all physical and virtual ports, their addresses (WWNs for FC, IQNs/IPs for iSCSI), and their current link status.
54. When a "Write" occurs on a FlashArray, where is it first stored before being acknowledged to the host? A) DirectFlash Modules (SSDs) B) Controller RAM only C) Mirrored NVRAM (Non-Volatile RAM) D) Pure1 Cloud Answer: C Rationale: To ensure zero data loss and ultra-low latency, writes are logged to the NVRAM modules in both controllers simultaneously. Once mirrored in NVRAM, the "Write" is acknowledged. It is de-staged to flash later (asynchronous to the host). 55. A customer wants to implement "SafeMode" for their Protection Group. Who has the authority to permanently delete an eradicated snapshot while SafeMode is active? A) The local pureadmin user. B) The customer's IT Manager. C) No one; only a Pure Support authorized technician following a specific challenge/response protocol with the customer’s designated security contact. D) The snapshots delete themselves after 5 minutes. Answer: C Rationale: SafeMode is designed to prevent "insider threats" and ransomware. Even a compromised admin account cannot delete these snapshots. Only Pure Support, after multi-factor verification with the customer, can adjust the policy. 56. Which multipathing policy is required for a Linux host (RHEL/Ubuntu) connecting via NVMe-over-Fabrics (NVMe-oF)? A) DM-Multipath with Round Robin B) Native NVMe Multipathing (ANA) C) PowerPath D) Veritas Volume Manager Answer: B Rationale: NVMe-oF uses Asymmetric Namespace Access (ANA). Modern Linux kernels handle this natively without needing the older DM-Multipath daemon used for iSCSI/FC.
57. When performing a "Controller Upgrade" (e.g., //X20 to //X50), what happens to the existing data on the flash modules? A) It must be backed up and restored. B) It stays in place (Data-in-Place Upgrade). C) It is formatted and wiped. D) It is moved to the second controller's RAM. Answer: B Rationale: Pure's "Evergreen" architecture allows for Data-in-Place upgrades. You simply swap the controllers; the new, more powerful controllers "take over" the existing flash modules without moving any data. 58. What is the default "Protection Group" retention policy for local snapshots? A) Keep all snapshots forever. B) 24 hours of hourly snapshots, 7 days of daily snapshots. C) 1 hour. D) There is no default; it must be configured. Answer: B Rationale: While customizable, the standard Purity template defaults to a 24-hour/7-day rotation to provide a baseline level of data protection upon creation. 59. A specialist is using the REST API to automate volume creation. Which HTTP method is used to create a new resource on the array? A) GET B) POST C) PUT D) DELETE Answer: B Rationale: In RESTful architecture, POST is used to create a new object (volume, host, etc.), while GET is used to retrieve data and PATCH/PUT is used to modify existing data. 60. What is the maximum number of controllers in a single FlashArray chassis? A) 1 B) 2 C) 4 D) 8 Answer: B Rationale: All FlashArray models use a dual-controller, Active/Active (optimized) architecture for high availability.
replication connectivity (Port 8117). Firewalls or VLAN misconfigurations are the most common causes of this alert.
65. What is the purpose of "Volume Groups" in Purity//FA? A) To increase the speed of the volumes. B) To logically group volumes for easier capacity reporting and management. C) To encrypt a subset of data. D) To allow volumes to share a LUN ID. Answer: B Rationale: Volume Groups are administrative containers. They do not affect data layout but allow an admin to see the "Total Capacity" used by a specific application suite (e.g., all volumes belonging to "Exchange"). 66. When initializing a FlashArray, what is the significance of the "Secondary" network? A) It is a backup for the Management network. B) it is used specifically for Replication and iSCSI traffic. C) it is for the Pure1 mediator only. D) It is for serial console access. Answer: B Rationale: Purity separates Management traffic from Data/Replication traffic. The Secondary network handles the heavy lifting of moving data between arrays or to hosts. 67. In a Fibre Channel environment, what is "NPIV" (N_Port ID Virtualization)? A) A way to hide the WWNs. B) A technology that allows one physical FC port to act as multiple virtual ports (used in ActiveCluster). C) A type of FC cable. D) A zoning method. Answer: B Rationale: FlashArray uses NPIV for "Virtual Port" technology, allowing the Virtual IP (VIP) of the array to migrate between controllers during a failover without the host needing to re-scan. 68. How does Purity handle "Garbage Collection"? A) It runs a scheduled task at midnight. B) It is managed globally by the DirectFlash software to ensure it doesn't conflict with host I/O. C) The host OS must send a TRIM command manually. D) FlashArray does not need garbage collection.
Answer: B Rationale: Traditional SSDs do garbage collection at the drive level, causing "latency spikes." Pure's DirectFlash software manages this globally, coordinating it across all modules to ensure it never impacts production I/O.
69. Which command is used to safely "shut down" a FlashArray controller for maintenance? A) purehw stop CT B) purecontroller halt C) purecontroller stop D) puresetup --shutdown Answer: C Rationale: purecontroller stop is the correct command to gracefully shut down an individual controller while the peer remains active. 70. What is the "Eradication" timer default setting? A) 1 hour B) 24 hours C) 7 days D) 30 days Answer: B Rationale: By default, deleted volumes/snapshots are held for 24 hours before permanent eradication. This gives the admin a window to "undestroy" an item deleted in error. 71. A host is experiencing high latency, but the array "Load" is 10%. What is the most likely bottleneck? A) Array CPU. B) The SAN fabric (congestion/oversubscription) or host-side queuing. C) The SSDs are too slow. D) The Purity version is too new. Answer: B Rationale: If the array Load is low but latency is high, the "wait time" is occurring outside the array—likely in the switches (ISL congestion) or because the host has reached its max queue depth. 72. When configuring "ActiveCluster", why is it a Best Practice to have a third site for the Mediator? A) To store a third copy of the data. B) To ensure the Mediator isn't lost if an entire site (Array A + Mediator) goes offline.
