質問 # 40
A network admin is trying to setup Pure1 access and phone home logging on the array.
What port should the admin ensure is opened for the array?
正解：A
解説：
Pure1 and Phone Home: Pure1 is a cloud-based management and monitoring platform. For the FlashArray to communicate its health data, performance metrics, and alerts to Pure Storage, it must be able to "Phone Home." The Power of HTTPS: This communication is encrypted and sent via the HTTPS protocol. Consequently, the standard port for HTTPS, TCP 443, must be opened for outbound traffic on the management network.
Firewall Configuration: The array controllers initiate an outbound connection to the Pure Storage cloud (specifically to destinations like cloud-connect.purestorage.com). Because it is an outbound-initiated connection, most stateful firewalls will allow the return traffic automatically once port 443 is permitted.
Why Option A is incorrect: Port 22 (SSH) is used for secure shell access to the array's CLI. While essential for local administration, it is not used for the automated Phone Home or Pure1 telemetry data stream.
Why Option B is incorrect: Port 8117 was historically used for the "Remote Assist" tunnel in older Purity versions. However, even for Remote Assist, modern Purity versions have transitioned to using port 443 to simplify firewall rules for customers. It is not the standard port for the general Phone Home/Pure1 logging service.
Verification: An administrator can verify connectivity by running the purearray test phonehome command in the CLI. If port 443 is blocked, the test will fail with a connection timeout.

What is unified storage for Pure?
正解：A
解説：
Definition of Unified Storage: In the storage industry, "Unified Storage" refers to a platform that can natively serve both Block-level storage (accessed via protocols like Fibre Channel, iSCSI, or NVMe-oF) and File-level storage (accessed via protocols like NFS or SMB) from a single pool of capacity and under a single management interface.
Pure Storage Implementation (FA File): Pure Storage achieved unified storage on the FlashArray through the introduction of Purity//FA File Services. Unlike traditional unified storage that often required a "gateway" or separate hardware "heads," Pure's implementation runs natively on the FlashArray controllers.
Shared Resources: On a unified FlashArray, the global storage pool is shared between volumes (Block) and file systems (File). All of Pure's core data services-such as deduplication, compression, and SafeMode snapshots-apply globally across both block and file data.
Protocol Diversity: While Option A mentions NFS and SMB, those are strictly File protocols. Option C mentions iSCSI and FC, which are strictly Block protocols. Only Option B correctly identifies the combination of Block and File, which defines the "Unified" architecture of the FlashArray.
質問 # 42
Where can a snapshot be copied out to?
正解：A
解説：
On a Pure Storage FlashArray, volume snapshots are immutable, read-only, point-in-time representations of your data. Because they cannot be attached directly to a host to be read or modified, you must use the Copy function to make the data usable.
The Purity operating environment allows you to copy a snapshot to two specific destinations:
A new volume: This effectively creates a clone. It provisions a brand-new, writable volume using the exact data footprint of the snapshot. This is incredibly useful for test/dev environments, offline reporting, or granular file recovery where you don't want to disrupt the original production volume.
An existing volume: This takes the data from the snapshot and completely overwrites the target volume. This is the standard procedure when you need to perform a full rollback of a corrupted volume, or when you want to quickly refresh a lower-level environment (like refreshing a QA database with yesterday's Production snapshot).
Here is why the other options are incorrect:
A new Snapshot (B & C): You cannot directly "copy" a snapshot to create another standalone snapshot. Snapshots are uniquely generated from active volumes. If you wanted to duplicate a snapshot's exact state, you would first copy it to a volume, and then take a new snapshot of that resulting volume.
質問 # 43
FlashArray sent Alert 51 - Protection Group Replication Delayed.
What steps should be taken?
正解：A
解説：
Understanding Alert 51: On a Pure Storage FlashArray, Alert 51 signifies that a Protection Group's replication is lagging behind its scheduled completion time. This does not necessarily mean the connection is "down," but rather that the volume of data being sent is exceeding the available throughput or is being queued behind other tasks.
The Triage Process:
Open Alerts: You must check for related alerts (like Alert 20 for "Replication Connection Down") to determine if the delay is caused by a total link failure or just congestion.
Replication Jobs in Progress: Because FlashArray uses a specialized engine to manage replication, having multiple large snapshots from different Protection Groups replicating simultaneously can saturate the "replication pipe." Checking active jobs helps determine if there is a scheduling "traffic jam." Replication Bandwidth: Comparing the current outgoing replication throughput against the historical average or the physical limit of the replication ports helps identify if the delay is due to a sudden increase in Data Change Rate (churn) or a reduction in network performance.
Why Option B is incorrect: If a Protection Group were disabled, replication wouldn't be "delayed"-it would be stopped, which triggers a different alert state. Cabling issues usually result in "Connection Down" alerts rather than just "Delayed" alerts.
Why Option C is incorrect: Disconnecting replication is a destructive troubleshooting step that will only increase the lag and RPO. You should always analyze the existing data flow before breaking the connection.
質問 # 44
What should an administrator configure when setting up device-level access control in an NVMe/TCP network?
正解：C
解説：
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.
