Pure Storage Pure Certified FlashArray Storage Professional FlashArray-Storage-Professional Prüfungsfragen mit Lösungen (Q69-Q74):

69. Frage
How are in-progress asynchronous snapshot transfers monitored from the UI?

Antwort: B

Begründung:
According to official Pure Storage documentation regarding Asynchronous Replication management, while replication throughput (bandwidth) can be viewed globally on the Analysis tab, the actual replication status for in-progress snapshot transfers is tracked and monitored on the replication target.
To monitor an in-progress asynchronous transfer from the GUI, a storage administrator must log into the target FlashArray, navigate to Storage -> Protection Groups, and look at the Transfers section within the Protection Group Snapshots panel. This view explicitly details the time the replicated snapshot was created on the source, the time the transfer started, and the current progress of the snapshot being received. If a transfer is currently in-progress, the "Completed" column will remain blank until the snapshot is fully safely written to the target array.
Here is why the other options are incorrect:
From the replication source (C): While the source orchestrates the creation of the snapshot and initiates the data push, the granular transfer completion status and historical transfer logs of the incoming snapshots are tracked on the target's Protection Group interface.
From the either the replication source or target (B): Because the specific "Transfers" tracking panel for asynchronous protection group snapshots is located on the receiving end (target), monitoring the granular completion status cannot be done symmetrically from either side in the UI.


70. Frage
What should an administrator configure when setting up device-level access control in an NVMe/TCP network?

Antwort: C

Begründung:
In any NVMe-based storage fabric (including NVMe/TCP, NVMe/FC, and NVMe/RoCE), the standard method for identifying endpoints and enforcing device-level access control is the NQN (NVMe Qualified Name).
The NQN serves the exact same purpose in the NVMe protocol as an IQN (iSCSI Qualified Name) does in an iSCSI environment, or a WWPN (World Wide Port Name) does in a Fibre Channel environment. It is a unique identifier assigned to both the host (initiator) and the storage array (target subsystem). When setting up access control on a Pure Storage FlashArray, the storage administrator must capture the Host NQN from the operating system and configure a Host object on the array with that specific NQN. This ensures that only the authorized host can discover, connect to, and access its provisioned NVMe namespaces (volumes).
Here is why the other options are incorrect:
VLANs (A): Virtual LANs are used for network-level isolation and segmentation at Layer 2 of the OSI model. While you might use a VLAN to separate your storage traffic from your management traffic, it is a network security measure, not a device-level access control mechanism for the storage protocol itself.
LACP (C): Link Aggregation Control Protocol (LACP) is a network protocol used to bundle multiple physical network links into a single logical link for redundancy and increased bandwidth. It has nothing to do with storage access control or mapping volumes to hosts.


71. Frage
A storage administrator is configuring a new volume and wants to provision 500GB. If the administrator accidentally selects PB, what will happen?

Antwort: A

Begründung:
Pure Storage FlashArrays utilize Thin Provisioning as a core, always-on architectural principle. When a volume is created, the "size" assigned to it is merely a logical limit (a quota) presented to the host; no physical back-end flash capacity is allocated or "pinned" at the time of creation.
Because of this architecture, Purity allows administrators to create volumes that are significantly larger than the actual physical capacity of the array (this is known as over-provisioning). If an administrator accidentally selects PB (Petabytes) instead of GB, the Purity GUI will allow the volume to be created because it is a logical operation that doesn't immediately consume 1PB of physical flash. However, Purity includes a built-in safety check: if the requested logical size is exceptionally large or exceeds the current physical capacity of the array, the GUI will present a warning or confirmation prompt to ensure the administrator is aware of the massive logical size being provisioned before finalizing the change.
Here is why the other options are incorrect:
The volume will be created and space will immediately be used (A): This describes "Thick Provisioning," which Pure Storage does not use. Space is only consumed on a FlashArray when unique data is actually written by the host and processed by the deduplication and compression engines.
The volume will not be created and a warning will be displayed (C): Purity does not strictly forbid over-provisioning. While it warns the user to prevent human error, it does not block the creation of the volume, as over-provisioning is a standard practice in thin-provisioned environments.


72. Frage
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?

Antwort: C

Begründung:
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.


73. Frage
An application engineer reports seeing high latency in their application running in a VMware instance.
What is the best method to determine the source of the latency?

Antwort: B

Begründung:
Within the Pure Storage ecosystem, the absolute best method to troubleshoot and pinpoint the exact source of VMware latency is to use VM Analytics (VM Topology) in Pure1.
VM Analytics is a feature built directly into Pure1 that maps the entire data path from the virtual machine all the way down to the physical FlashArray. It provides a visual topology map detailing the VM, Virtual Disk, ESXi Host, Datastore, and FlashArray Volume. By analyzing performance across this topology, an administrator can instantly identify exactly where the latency is being introduced. For example, you can clearly see if the latency spikes at the ESXi host layer (indicating compute contention) or the network layer, even if the FlashArray volume itself is reporting sub-millisecond latency at the storage level.
Here is why the other options are incorrect:
Analyze load metrics in Pure1 for each volume in the user's data path (C): Looking exclusively at volume-level metrics on the FlashArray will only tell you the latency from the array's perspective. If the latency is being caused by an overloaded ESXi host CPU or a saturated SAN fabric, the FlashArray metrics will look perfectly healthy, and you will fail to identify the source of the problem.
Analyze performance charts in vSphere for CPU, Memory, Network, and Storage Path for the user's data path (B): While vCenter performance charts are useful, they often lack deep storage-array-level context. Pure1's VM Topology is the "best" method because it correlates the vSphere stack data with the native FlashArray telemetry data in a single, unified view, making full-stack root cause analysis much faster.
