, 1.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?
A. The FlashArray User Guide
B. FlashArray Transceiver and Cable Support article
C. The Port Usage and Definitions article
Answer: B
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.
2.When is it possible to simulate snapshot policies in the Pure1 Snapshot Policies (SafeMode)?
A. When a FlashArray has existing snapshots
B. When a FlashArray does not have existing snapshots
C. When a FlashArray has an existing saved workload simulation
Answer: A
Explanation:
In Pure1, the ability to simulate snapshot policies—particularly when assessing the capacity requirements
and impact of enabling SafeMode—heavily relies on historical telemetry data. Pure1 uses the data from
existing snapshots on the FlashArray to calculate the environment's daily data change rate, as well as the
deduplication and compression ratios specific to those workloads.
By analyzing the footprint of existing snapshots, Pure1's analytics engine can accurately project the future
storage capacity required if you were to change your snapshot frequency or extend the retention period
(for example, locking them down for 7 to 30 days under a SafeMode policy). If a FlashArray does not have
any existing snapshots, Pure1 lacks the foundational baseline metrics needed to simulate and forecast
the capacity impact of a proposed snapshot policy.
3.What command must an administrator run to use newly installed DirectFlash Modules (DFM)?
A. pureadmin -- admit-drive
B. purearray admit drive
