NEW QUESTION # 72
A new array is directly connected to a host with Direct Attach Copper (DAC) cables. The link does not come up.
Which document can be used to help identify the issue?
Answer: C
Explanation:
When physical links fail to establish-especially when using Direct Attach Copper (DAC) cables or Twinax-the most common culprit is a hardware compatibility mismatch. Pure Storage arrays have specific requirements for optics and cabling to ensure optimal signal integrity and performance.
The FlashArray Transceiver and Cable Support article (available on the Pure Storage Support portal) is the authoritative, verified resource for this scenario. It provides a comprehensive, constantly updated compatibility matrix detailing exactly which vendor DAC cables (e.g., Cisco, Brocade, Arista) and transceivers are officially validated and supported for use with specific FlashArray models and port types. If an unsupported DAC cable is used, the switch or host bus adapter (HBA) on the array might simply refuse to bring the link up.
Here is why the other options are incorrect for this specific issue:
The FlashArray User Guide (A): This guide is excellent for day-to-day administration (volume creation, host grouping, etc.) but is too broad to contain granular, constantly updating hardware compatibility matrices for specific cables.
The Port Usage and Definitions article (C): This document explains the logical and physical purpose of the ports on the back of the controllers (e.g., defining which ports are used for management, replication, or host connectivity), but it does not dictate hardware transceiver or cable interoperability.
NEW QUESTION # 73
An administrator needs a comparison of FA File performance across multiple arrays.
What Pure1 Manage report will provide the best results?
Answer: A
Explanation:
Pure1 Manage Capabilities: Pure1 is a SaaS-based platform that provides a "single pane of glass" view across an entire fleet of FlashArrays. It excels at aggregating metrics that are otherwise siloed on individual arrays.
Specialized File Metrics: Because FlashArray File (FA File) operates as a specific service layer within Purity, its performance metrics (NFS/SMB latency, throughput, and IOPS) are tracked separately from traditional block storage.
The File Systems Performance Report: This specific report/view in Pure1 allows administrators to:
Select multiple file systems residing on different arrays.
Overlay their performance graphs to identify trends or outliers.
Filter by specific protocol (NFS vs. SMB) to see how different workloads are behaving across the infrastructure.
Why Options B and C are less ideal:
Overview Dashboard: While great for a "health at a glance" check (showing total capacity and high-level alerts), it does not provide the granular, side-by-side performance comparison required for a deep-dive analysis.
Array Performance: This report typically shows the total load on the controllers. While this includes file traffic, it often aggregates it with block traffic, making it difficult to isolate how the file services specifically are performing across the fleet.
Analytical Advantage: Using the File Systems Performance report allows the administrator to correlate performance spikes with specific file-level events, such as a large backup job or a high-intensity data migration occurring on one array versus another.
NEW QUESTION # 74
A FlashArray//XL is used for NVMe-RoCE services. The array has been lightly loaded and has performed as expected. A new workload has been added to the array, which is within the array's performance envelope. The change has resulted in extreme latency and service outages for all workloads utilizing NVMe-RoCE.
Which misconfiguration is this a symptom of?
Answer: B
Explanation:
Requirement for Lossless Ethernet: NVMe over RoCE (RDMA over Converged Ethernet) requires a lossless fabric to function correctly. Unlike standard iSCSI which uses TCP for error recovery, RoCE assumes the network will not drop packets. If the network is "lossy," performance degrades significantly.
The Role of PFC: Priority Flow Control (PFC) (IEEE 802.1Qbb) is the specific mechanism used in Data Center Bridging (DCB) to provide flow control on a per-priority basis. It allows the switch to send a "pause" frame to the sender when buffers are full, preventing packet drops.
Symptom Analysis: In the scenario provided, the array itself is not overloaded ("within the performance envelope"). However, the addition of a new workload increased traffic to the point where buffer congestion occurred. Because PFC was likely misconfigured (either on the FlashArray ports, the network switches, or the host NICs), the network dropped packets instead of pausing traffic. This leads to "go-back-N" retransmissions and massive latency spikes that affect all workloads sharing that fabric.
Pure Storage Best Practices: Pure Storage documentation for NVMe-RoCE emphasizes that PFC must be enabled and consistent across the entire path. If there is a mismatch in PFC configuration, the resulting packet loss will cause the symptoms described: extreme latency and potential service outages.
NEW QUESTION # 75
What is the Pure Storage recommended Maximum Transmission Unit (MTU) size for the replication ports on a FlashArray?
Answer: B
Explanation:
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.
NEW QUESTION # 76
An administrator is preparing an array pair for ActiveDR and is trying to calculate the total minimum bandwidth requirement.
What percent of bandwidth above the incoming write rate should be allocated to accommodate for unexpected write bursts and still maintain near-sync RPO?
Answer: C
Explanation:
ActiveDR Bandwidth Sizing: ActiveDR is a continuous, asynchronous replication technology designed to provide near-zero RPO. Because it streams data continuously rather than in discrete snapshot intervals, the bandwidth between the source and target arrays must be able to handle the application's write workload.
Handling Write Bursts: Application workloads are rarely flat; they have peaks and valleys. If you size the bandwidth exactly to the average change rate, any burst in write activity will cause the replication lag to increase, thereby increasing your RPO.
The 30% Rule: Pure Storage best practices and sizing guides recommend providing a 30% buffer (headroom) above the measured average write rate. This extra capacity ensures that during a high-IO period, the replication engine has enough "pipe" to catch up quickly and return to a near-sync state.
Calculation Example: If a workload generates an average of 100 MB/s of new unique data, the administrator should ensure at least 130 MB/s of usable, dedicated bandwidth is available between the sites.
Consequences of Under-sizing: If only 10% (Option A) is used, the array may struggle to recover from even minor bursts, leading to a consistently climbing RPO. 50% (Option B) is often considered safe but can be cost-prohibitive or overkill for standard networking budgets unless the workload is exceptionally volatile.
