質問 # 15
Which protection group cannot be ratcheted for SafeMode?
正解：C
質問 # 16
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?
正解：B
解説：
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.
質問 # 17
An administrator is attempting to add a volume to a volume group but it does not show up in the list of volumes available to move in, even though it does show up in the volumes pane.
Why is the volume missing?
正解：A
解説：
In the Pure Storage Purity operating environment, a volume can only be a member of one Volume Group at a time.
When an administrator navigates to a Volume Group in the GUI and clicks to add members, the system filters the inventory and only displays volumes that are currently "unassigned" (not belonging to any Volume Group). If a volume is already residing inside another Volume Group, Purity intentionally hides it from this available list to prevent conflicting overlapping memberships. To resolve this, the administrator must first navigate to the volume's current Volume Group, remove the volume from that group, and then it will become available to add to the new one.
Here is why the other options are incorrect:
It is already part of a Protection Group (B): Protection Groups (pgroups) manage snapshot and replication schedules. A volume can absolutely be a standalone member of a Protection Group while simultaneously being added to a Volume Group. Being in a pgroup does not hide it from the vgroup selection list.
It is protected by SafeMode (C): SafeMode is a ransomware protection feature that prevents the manual eradication of destroyed volumes and snapshots before their retention timer expires. It does not dictate or restrict logical organizational containers like Volume Groups.
質問 # 18
How would a FlashArray administrator view external latency for write requests for a specific volume?
正解：B
解説：
In the Pure Storage FlashArray GUI, granular performance metrics (Latency, IOPS, Bandwidth) are located under the Analysis > Performance tabs. When you navigate to the Volumes sub-tab and select a specific volume, Purity displays a unified line graph tracking the performance of that volume over time.
By default, the Latency graph simultaneously plots Read, Write, and Mirrored Write (for volumes participating in an ActiveCluster or synchronous replication pod) latencies. Because these lines can overlap or compress the Y-axis (especially if one metric spikes), isolating a specific metric requires interacting with the graph's legend.
To view the exact, un-obscured latency for standard write requests to that volume, the administrator should click on "Read" and "Mirrored Write" in the chart's legend. This deselects those metrics, effectively hiding their lines from the graph and automatically rescaling the view to exclusively display the host write latency.
Here is why the other options are incorrect:
Health > Network (A): The Health tab is used to check the hardware status of the physical controller ports, including link state and errors. While you might see port-level throughput or queue depth here, it does not provide volume-specific application latency.
Storage > Volumes > Details (B): The Storage tab is primarily used for provisioning and configuration management. Clicking on a volume here will show its size, data reduction ratio, snapshot policies, and connected hosts, but it does not provide detailed interactive performance graphs.
質問 # 19
What is the Pure Storage recommended Maximum Transmission Unit (MTU) size for the replication ports on a FlashArray?
正解：A
解説：
Understanding MTU: The Maximum Transmission Unit (MTU) defines the largest size of a packet or frame that can be sent in a single network transaction. The standard Ethernet MTU is 1500 bytes. Anything larger than 1500 bytes is referred to as a Jumbo Frame.
Replication Efficiency: Replication involves moving large amounts of data between arrays. Using standard 1500-byte frames results in higher overhead because the CPU must process a larger number of headers for the same amount of data. By increasing the MTU, the FlashArray can pack more data into each frame, reducing CPU interrupts and improving overall throughput.
The Pure Recommendation: Pure Storage specifically recommends an MTU of 9000 for both iSCSI and Replication traffic. This is the industry standard for Jumbo Frames that balances efficiency with compatibility across most enterprise-grade switches.
Configuration Requirements: It is critical to remember that MTU must be configured end-to-end. For an MTU of 9000 to work on the replication ports:
The FlashArray replication ports must be set to 9000.
The network switches along the path (and any routers/ISLs) must support and be configured for at least 9000.
The target array's replication ports must also be set to 9000.
Why 9216 (Option A) is incorrect: While some switches support a "Baby Giant" or slightly larger MTU like 9216 to account for VLAN tagging overhead, Pure's internal and best practice documentation specifically points to 9000 as the standard setting for the array's interface.
