질문 # 65
What is the Pure Storage recommended Maximum Transmission Unit (MTU) size for the replication ports on a FlashArray?
정답：C
설명：
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.
질문 # 66
In reviewing space metrics via the Pure Management GUI, a storage manager notices the total reduction rate is much higher than the Data Reduction Rate (DRR).
What is the reason for this?
정답：C
설명：
Understanding Data Reduction Rate (DRR): DRR is a measure of the effectiveness of Purity's deduplication and compression algorithms. It compares the amount of data written by the host to the amount of physical space actually occupied on the flash media after these processes have occurred.
Calculation: $\text{DRR} = (\text{Deduplication} \times \text{Compression})$.
Understanding Total Reduction: The Total Reduction metric is a broader "efficiency" value. It represents the ratio of the Total Provisioned (logical) space to the Physical space used.
The "Thin Provisioning" Factor: The primary difference between these two numbers is Thin Provisioning.
FlashArrays are 100% thin-provisioned by default. If a customer creates a 100TB volume but the host only writes 1TB of data, the "Total Reduction" will be massive because it counts all that unwritten, "virtual" space as "saved." The DRR, however, only looks at the 1TB that was actually written and calculates how well it was compressed and deduped.
Why Option C is incorrect: Both metrics generally account for the efficiency of snapshots. However, snapshots contribute to DRR through deduplication (since they share blocks with the source volume). The massive gap between DRR and Total Reduction is almost always mathematically attributed to the "unwritten" space provided by thin provisioning.
Key Takeaway: If your DRR is 5-to-1 but your Total Reduction is 50-to-1, it means your data is compressing/deduping well, but you have also provisioned a significant amount of volume space that hasn't been written to yet.
질문 # 67
What is the best practice for configuring VMFS UNMAP for ESXi 6.7 or later?
정답：B
설명：
What is UNMAP?: UNMAP (SCSI command 0x42) is the mechanism that allows a host (like ESXi) to inform the storage array that specific blocks of data are no longer in use (e.g., after a VM is deleted or moved). This is critical for Pure Storage because it allows the array to reclaim that space and maintain high data reduction ratios.
Evolution in ESXi: In versions prior to 6.5, UNMAP was a manual process executed via the CLI. Starting with ESXi 6.7, VMware introduced Automatic Space Reclamation, which runs in the background.
The Pure Storage Recommendation: Pure Storage recommends setting the reclamation priority to Auto with Low Priority.
Low Priority: This ensures that the UNMAP commands are sent to the FlashArray at a steady, manageable rate (roughly up to 25 MB/s to 100 MB/s depending on the Purity version). Because FlashArrays are built on a high-performance metadata engine, "Low Priority" is more than sufficient to keep up with even high-churn environments without causing any contention for active application I/O.
Why avoid High Priority (Option B)?: Setting it to high priority or using a fixed high-burst rate can lead to "bursty" SCSI traffic. While the FlashArray can handle the load, it is considered a best practice to keep background maintenance tasks like space reclamation at a lower priority to ensure the "Big Three" (latency, bandwidth, IOPS) for production workloads remain optimized.
Verification: You can verify that UNMAP is working by looking at the Data Reduction metrics in the Purity GUI or Pure1. If the "Thin Provisioning" or "Reclaimed" numbers are increasing after file deletions, the host is correctly communicating its freed space to the array.
질문 # 68
How would a FlashArray administrator view external latency for write requests for a specific volume?
정답：B
설명：
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.
질문 # 69
A storage administrator is tasked with providing real-time data and alerts to the Network Operations Center (NOC) dashboard.
What source should the information come from to provide real-time data?
정답：C
설명：
To provide true real-time data and alerts directly to a Network Operations Center (NOC) dashboard, the information must be sourced directly from the FlashArray. The FlashArray's Purity operating environment natively supports real-time data streaming and alerting integrations via protocols like Syslog, SNMP traps, and the local REST API. Polling the array directly or configuring it to push alerts guarantees that the NOC receives instantaneous, up-to-the-second notifications regarding array health, hardware faults, and performance metrics.
Here is why the other options are incorrect:
Pure1 (B): While Pure1 is Pure Storage's powerful, cloud-based monitoring and predictive analytics platform, it relies on phone-home telemetry data. This telemetry is batched and transmitted from the array to the Pure1 cloud on a short polling interval (typically a few minutes). Because of this transmission and processing interval, Pure1 provides near-real-time (lagging by a few minutes) and historical data. It is excellent for global fleet management and predictive support, but not for instantaneous, zero-latency NOC alerting.
Pure Performance Monitoring (A): This is a distractor. There is no standalone product or specific protocol in the Pure Storage ecosystem officially named "Pure Performance Monitoring." Performance monitoring is simply a feature accessed via the FlashArray GUI/CLI or the Pure1 platform.
