질문 # 25
Refer to the exhibit:
What is the most likely cause of system space in this capacity graph?
정답：B
설명：
Analyzing the Graph: The provided capacity graph shows a sharp, vertical drop in Unique and Shared space (the teal/green sections) at approximately 10:45. Simultaneously, there is a massive spike in System space (the grey shaded area).
The "System" Space Spike: In Purity, when a volume is deleted and eradicated, the data isn't physically wiped from the flash modules instantly. Instead, the logical references are removed, and the blocks are moved into a "Pending Reclamation" state. In older versions of Purity reporting (or specific views), this pending work is often categorized under System space until the background Garbage Collection (GC) process can physically reclaim it.
The Decay Curve: Notice the grey "System" area gradually tapers down over the following hours (from 11:00 to 14:00). This is the visual representation of the array's Garbage Collection engine working in the background to physically free up those blocks.
Why Option C is incorrect: If SafeMode were enabled, the space would not move into "System" space in this manner; it would remain locked in the Snapshots or Destroyed bucket for the duration of the retention period, preventing the graph from dropping at all.
Why Option A is incorrect: If space reclamation stopped working, the grey "System" area would stay flat and would not decay over time. The fact that it is trending downward proves that reclamation is actively processing the deleted volume.
질문 # 26
What command must an administrator run to use newly installed DirectFlash Modules (DFM)?
정답：A
설명：
When new DirectFlash Modules (DFMs) or data packs are physically inserted into a Pure Storage FlashArray, the Purity operating environment detects the new hardware but places the drives in an "unadmitted" state. This safety mechanism prevents the accidental incorporation of drives and allows the system to verify the firmware and health of the modules before they are actively used to store data.
To formally accept these drives into the system's storage pool so their capacity can be utilized, the administrator must execute the CLI command puredrive admit. Once this command is run, the drive status transitions from "unadmitted" to "healthy," and the array's usable capacity expands accordingly.
Here is why the other options are incorrect:
pureadmin -- admit-drive (A): This is syntactically incorrect. The pureadmin command suite is used for managing administrator accounts, API tokens, and directory services, not for hardware or drive management.
purearray admit drive (B): This is also incorrect syntax. While purearray is used for array-wide settings and status (like renaming the array or checking space), specific drive-level operations are exclusively handled by the puredrive command structure.
질문 # 27
A FlashArray administrator is configuring new hosts. There is an option in the personality settings for the target OS.
When is the best time to configure the personality for a host in Purity?
정답：A
설명：
Definition of Host Personality: In Purity//FA, a Host Personality is a setting applied to a host object that modifies how the FlashArray communicates with that specific initiator. It ensures the array sends the correct SCSI responses that the target Operating System (OS) expects. Common personalities include ESXi, AIX, HP-UX, and Hitachi-VSP.
The Importance of Timing: The best practice is to set the personality during the host creation phase, before any volumes are attached or I/O has commenced. This ensures that from the very first "Inquiry" command sent by the host, the FlashArray responds with the appropriate settings (such as specific VAAI primitives for ESXi or specific ALUA behaviors for other Unix variants).
Risks of Changing Later: While Purity allows you to change a host personality later, doing so while volumes are connected and I/O is active can be disruptive. For many operating systems, a change in personality requires the host to be rebooted or the storage paths to be "rescanned" to recognize the change in device capabilities.
Default Behavior: If no personality is selected, the FlashArray uses a "Generic" personality suitable for standard Windows and Linux distributions. However, for specialized hypervisors like ESXi, failing to set the personality correctly from the start can lead to performance issues or lack of support for hardware acceleration features.
Why Option C is incorrect: Changing the personality after volumes are connected is reactive rather than proactive. It increases the risk of the host misinterpreting the storage device's capabilities, potentially leading to mount failures or path instability.
질문 # 28
A customer with an X50R2 array connected to 110V power is due for an upgrade to the latest controller generation.
What is required to allow this upgrade to proceed?
정답：B
설명：
As Pure Storage has iterated through FlashArray generations (moving from //X R2 to R3, R4, and beyond), the power density and performance capabilities of the controllers have increased significantly. Modern high-performance controllers, such as those found in the //X R4 or //XL series, have strict power requirements that often exceed what a standard 110V/120V (Low-Line) circuit can provide.
To support the higher wattage and current draw of modern CPUs and NVRAM modules, Pure Storage requires 200-240V (High-Line) power for its latest generation controllers. If an existing array is currently running on 110V power, it must be migrated to 220V power outlets before the upgrade can proceed. Attempting to run newer, high-spec controllers on 110V power could lead to power supply instability, insufficient cooling performance, or the controllers failing to boot entirely.
Here is why the other options are incorrect:
Call support to schedule a power supply replacement (A): The issue is not a faulty power supply; it is the external electrical infrastructure's inability to provide the necessary voltage/wattage for the new hardware. Replacing the power supply with the same model would not solve the voltage limitation.
Transition the array to DC power (B): While Pure Storage does offer DC power options for specific telco environments, this is not a standard requirement for a typical controller upgrade. Moving to standard high-line AC power (220V) is the standard prerequisite for data center environments.
질문 # 29
What is the proper procedure for stopping asynchronous replication and in-progress transfers?
정답：B
설명：
According to the official Pure Storage FlashArray Asynchronous Replication Configuration and Best Practices Guide, the proper and immediate method to halt an active, in-progress asynchronous replication transfer is by disallowing the protection group at the target.
When you navigate to the target FlashArray and disallow the specific Protection Group, Purity immediately breaks the replication authorization for that group. If there is an in-progress snapshot transfer occurring at that exact moment, the transfer is immediately stopped, and the partially transferred snapshot data is discarded on the target side.
Here is why the other options are incorrect:
Disabling the replication schedule (B): Toggling the replication schedule to "Disabled" only prevents future scheduled snapshots from being created and sent. It does not kill or interrupt a replication transfer that is already currently in progress.
Removing the volume member from a protection group (A): Modifying the members of a protection group updates the configuration for the next snapshot cycle. It does not actively abort the transmission of the current point-in-time snapshot that the array is already busy sending over the WAN.
