Pure Storage Certified FlashArray Implementation Specialist 認定 FlashArray-Implementation-Specialist 試験問題 (Q173-Q178):

質問 # 173
A customer's management network connectivity is NOT available at the time of array deployment. Which switch should an Implementation Engineer use to avoid those checks during puresetup flow?

正解：C

解説：
The puresetup initialization script automatically runs a series of network validation tests to ensure the array can reach default gateways, DNS servers, and Pure1. If the management network is not yet live or is air-gapped during the install, these tests will fail, potentially blocking the setup process.
To proceed with the initialization despite the missing network, the Implementation Engineer must append the --skip-management-connectivity-tests flag to the puresetup command.
This flag instructs the script to bypass the ping/DNS lookup checks on the management interface.
It allows the engineer to complete the array initialization (naming, IP assignment) so the array is "up" and ready for local config, with the understanding that full management connectivity will be established and verified later.

質問 # 174
What is the speed of the Ethernet ports to connect a FlashArray //E to a DFS?

正解：B

解説：
FlashArray//E models utilize 25Gb Ethernet (25G) ports for connecting to DirectFlash Shelves (DFS). These 25G ports are designed to handle the high throughput demands of DFS, providing efficient data transfer between the storage array and expansion shelves. This configuration ensures optimal performance and scalability for FlashArray//E systems.


質問 # 175
FlashArray//C and //E models use which flash storage architecture, identifiable by gray tabs on the DirectFlash Module carriers?

正解：A

解説：
The Pure Storage product portfolio is strategically segmented to address different tiering requirements in the modern datacenter. While the FlashArray//X and FlashArray//XL are optimized for absolute performance and ultra-low latency using Triple-Level Cell (TLC) flash and Storage Class Memory (SLC), the FlashArray//C and FlashArray//E lines are engineered specifically for capacity consolidation and tier-2 workloads.
To achieve massive storage density at a much lower cost per terabyte, the //C and //E models exclusively utilize Quad-Level Cell (QLC) flash architecture. QLC technology stores four bits of data per NAND cell, significantly increasing physical capacity compared to TLC, while the Purity operating system intelligently mitigates the inherent wear-leveling and write-amplification challenges traditionally associated with dense QLC media.
Because QLC and TLC DirectFlash Modules (DFMs) share the exact same physical U.2 form factor and slot seamlessly into the identical drive bays, Implementation Engineers must be able to visually distinguish them onsite to prevent accidentally mixing drive types within a single chassis. Pure Storage strictly color-codes the physical release latches on the drive carriers to prevent this mistake: QLC DFMs feature distinct gray tabs , whereas standard TLC DFMs feature blue tabs. Identifying the gray tabs ensures the engineer is working with the correct //C or //E capacity modules before proceeding with the physical admission process.


質問 # 176
A FlashArray arrives with Purity 5.3.8 applied out of the factory. The account team requests that the array configured with Purity 6.1.21. Which steps should the Implementation Engineer select to meet this requirement?

正解：B

解説：
To upgrade from Purity 5.3.8 to 6.1.21 on a new array, the Implementation Engineer should create a bootable USB installer from the target ISO and reimage both controllers to ensure a clean and supported upgrade.


質問 # 177
What command should the Implementation Engineer run to view NVRAM install and update status?

正解：D

解説：
Within the Purity//FA operating system architecture, dedicated NVRAM modules (used heavily in standard non-DFMD arrays to provide non-volatile write caching) are fundamentally treated as specialized drives by the software layer. They are physically installed into specific central chassis bays labeled NVB0, NVB1, NVB2, and NVB3.
Because they are classified as drive components, the primary and most direct command an Implementation Engineer should use to verify their physical installation, health, capacity, and update status is puredrive list.
When this command is executed via the CLI, it generates a comprehensive table detailing every DirectFlash Module (DFM) and NVRAM module currently seated in the chassis.
The output explicitly shows the slot location (e.g., CH0.NVB0), the component's operational status (healthy, empty, evacuating, or updating), and its specific firmware version. While the purehw list command is excellent for viewing broader chassis components (like fans, temperature sensors, and controllers), puredrive list is the purpose-built command required to monitor the precise synchronization and firmware update phases of the NVRAM modules, especially crucial during a non-disruptive upgrade (NDU) when ensuring cache mirror integrity is paramount.
