질문 # 28
An administrator is running commands to verify NVME/TCP connectivity from the hosts to the FlashArray. They use the command ping -M do -s 8972 <ip_addr> from the initiator and it fails.
What should the administrator do to resolve the issue?
정답：A
설명：
When configuring NVMe/TCP (or iSCSI) for optimal performance on a Pure Storage FlashArray, configuring Jumbo Frames (an MTU of 9000) end-to-end is a standard best practice.
The command ping -M do -s 8972 <ip_addr> is specifically used to verify Jumbo Frame configuration across the network.
The -M do flag sets the "Do Not Fragment" (DF) bit, meaning the network is not allowed to break the packet into smaller pieces.
The -s 8972 flag sets the ICMP data payload to 8972 bytes. When you add the standard 8-byte ICMP header and the 20-byte IP header, the total packet size equals exactly 9000 bytes.
If this ping command fails, it indicates that somewhere along the network path between the host (initiator) and the FlashArray (target), a switch port, router, or network interface is not configured to support an MTU of 9000. The packet is being dropped because it is too large and cannot be fragmented. The administrator must verify the MTU settings on every network hop (switches, routers, and host NICs) to resolve the issue.
Here is why the other options are incorrect:
Engage support to enable NVME/ TCP services (A): The failure of a Jumbo Frame ping test is a Layer 2/Layer 3 network configuration issue, not an indicator that the NVMe/TCP storage protocol service is disabled on the array.
Run the command from the target (C): While pinging from the FlashArray back to the host is a valid secondary troubleshooting step, it will likely also fail if the network path doesn't support Jumbo Frames. The actual resolution is to fix the MTU on the network hops.
질문 # 29
What does an asynchronous blackout window prevent?
정답：C
설명：
Definition of a Blackout Window: In Purity//FA, a Blackout Window is a scheduled period during which asynchronous replication is suspended. This is typically used by administrators to preserve WAN bandwidth during peak business hours or to prevent replication traffic from competing with high-priority local workloads (like a massive database batch job).
The "In-Progress" Rule: One of the most important characteristics of a blackout window is that it is non-disruptive to active transfers. If a replication job started at 7:55 AM and the blackout window begins at 8:00 AM, Purity will allow that specific transfer to continue until it finishes.
The Prevention Mechanism: Once the clock hits the start of the blackout window, the replication scheduler is effectively "paused." No new snapshots will be queued for transfer, and no new replication sessions will be initiated until the window expires.
Why Option A is incorrect: Purity does not kill active transfers. Abruptly stopping a transfer would waste the bandwidth already consumed and require the entire delta-set to be re-calculated or re-sent later.
Why Option B is incorrect: The phrasing is logically inconsistent; you cannot prevent something that "started before" the window from being "new" during the window.
Best Practice: When configuring blackout windows, ensure that the "clear" time (the time between windows) is long enough to allow the array to catch up on the snapshots that were queued during the blackout, otherwise, you risk triggering Alert 51 (Replication Delayed).
질문 # 30
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?
정답：A
설명：
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.
질문 # 31
A FlashArray administrator has created a 1PB volume and wants to resize it to 1TB, but accidentally sets the new size to 1GB.
How can the administrator recover the potentially truncated data?
정답：A
설명：
Purity Safety Mechanism: In Pure Storage Purity, volume resizing-specifically downsizing-is a destructive operation because it can lead to data truncation. To protect against human error (like the one described in the scenario), Purity automatically creates a "pre-resize" snapshot of the volume before the change is committed.
The "Destroyed" Snapshot: When a volume is shrunk, Purity generates a snapshot of the volume in its state immediately before the shrink operation. This snapshot is placed in the Destroyed (or "Pending Eradication") bucket.
Recovery Process: To recover the data, the administrator does not simply "resize back up" (Option C), as the data beyond the 1GB mark may have already been unmapped or treated as truncated by the host file system. Instead, the administrator should locate the auto-generated snapshot in the Destroyed volumes/snapshots section, "recover" it to make it active again, and then either copy that snapshot to a new volume or overwrite the truncated volume from that snapshot.
SafeMode Integration: If SafeMode is enabled, these auto-generated snapshots are even more secure, as they cannot be manually eradicated before the timer expires, ensuring a guaranteed recovery point for accidental shrinks.
Why Option C is incorrect: Increasing the size of a volume back to 1TB (or 1PB) does not automatically restore the data that was logically removed or truncated when the volume was set to 1GB; the host file system would still see the data as corrupted or missing.
질문 # 32
How should an administrator configure initiator-to-target connections for zones with multiple initiators?
정답：C
설명：
Zoning Best Practices: In a Fibre Channel SAN environment, zoning is used to partition the fabric to ensure that initiators (hosts) can only see the targets (FlashArray ports) they are intended to communicate with.
The "Single Initiator" Rule: Pure Storage, following industry-standard SAN best practices (and Cisco/Brocade recommendations), strongly advises using Single Initiator Zoning. This means each zone should contain exactly one initiator (HBA port) and one or more targets (FlashArray ports).
Why Single Initiator to Multiple Targets (Option B)?:
Isolation: This prevents "Initiator-to-Initiator" communication. If multiple initiators are in the same zone, they may attempt to communicate with or probe each other (Registered State Change Notifications - RSCNs), which can cause host instability, driver timeouts, or discovery issues.
Troubleshooting: It simplifies troubleshooting. If a port is experiencing CRC errors or flapping, the impact is isolated to that specific host's zone rather than affecting a broad "group" zone.
Efficiency: When a target port changes state (e.g., during a controller reboot), the switch sends an RSCN. In a single-initiator zone, only that specific host is notified. In a multi-initiator zone, every host in the zone is interrupted to process the notification, even if they aren't using the port that changed.
Target Selection: While the zone should have only one initiator, it can (and should) include multiple target ports from the FlashArray (usually one port from CT0 and one from CT1 for the same fabric) to provide path redundancy and allow the host's MPIO software to manage failover.
