質問 # 55
A customer is managing a VMware environment and has recently copied a snapshot from a Pure Storage array to a new volume. When attempting to mount this volume on a VMware virtual machine, the operation fails.
How should this be resolved?
正解：A
解説：
VMFS UUID Conflict: When you create a volume from a snapshot on a FlashArray, the data is a block-for-block copy of the original. This includes the VMFS metadata and the unique identifier (UUID) of the datastore.
ESXi Protection Mechanism: When an ESXi host sees a volume that contains a VMFS signature identical to one already mounted (or one it has seen before but on a different device ID), it flags the volume as a "snapshot." To prevent data corruption or VM identity conflicts, VMware will not automatically mount this "duplicate" volume.
The Resignaturing Process: By choosing to Resignature the volume (via the "Mount Datastore" wizard in vCenter or the ESXi CLI), VMware assigns a new, unique UUID to the VMFS volume. This allows the host to treat it as a distinct, independent datastore.
Why Option B is incorrect: Reformatting the volume would indeed allow it to be mounted, but it would destroy all the data you just copied from the snapshot, defeating the purpose of the operation.
Why Option C is incorrect: While there are advanced settings in VMware (like LVM.enableResignature), they don't solve the issue of the operation "failing" during a standard mount attempt; they simply change how the host behaves. Resignaturing is the standard, safe, and recommended workflow for mounting snapshot copies in a VMware environment.

Refer to the exhibit:
What is the most likely cause of system space in this capacity graph?
正解：B
解説：
Analyzing the Graph: The provided capacity graph shows a sharp, vertical drop in Unique and Shared space (the teal/green sections) at approximately 10:45. Simultaneously, there is a massive spike in System space (the grey shaded area).
The "System" Space Spike: In Purity, when a volume is deleted and eradicated, the data isn't physically wiped from the flash modules instantly. Instead, the logical references are removed, and the blocks are moved into a "Pending Reclamation" state. In older versions of Purity reporting (or specific views), this pending work is often categorized under System space until the background Garbage Collection (GC) process can physically reclaim it.
The Decay Curve: Notice the grey "System" area gradually tapers down over the following hours (from 11:00 to 14:00). This is the visual representation of the array's Garbage Collection engine working in the background to physically free up those blocks.
Why Option C is incorrect: If SafeMode were enabled, the space would not move into "System" space in this manner; it would remain locked in the Snapshots or Destroyed bucket for the duration of the retention period, preventing the graph from dropping at all.
Why Option A is incorrect: If space reclamation stopped working, the grey "System" area would stay flat and would not decay over time. The fact that it is trending downward proves that reclamation is actively processing the deleted volume.

What method is recommended for monitoring an array with 3rd party tools such as Prometheus and SolarWinds?
正解：C
解説：
Modern Monitoring Standards: Pure Storage has built its management ecosystem around the REST API. While traditional methods like SNMP and Syslog are supported for basic health alerts, the REST API provides the depth of data (granularity) and the performance required for modern observability platforms like Prometheus, SolarWinds, and Grafana.
The Pure Storage Exporter: For tools like Prometheus, Pure Storage provides an official "Pure Exporter." This exporter acts as a bridge; it queries the FlashArray via the REST API to gather real-time metrics (latency, bandwidth, IOPS, capacity) and converts them into the format Prometheus understands.
SolarWinds Integration: SolarWinds utilizes the Pure Storage REST API to pull performance and health data into its storage monitoring modules. This allows for deep-dive historical analysis that exceeds the capabilities of simple SNMP traps.
Why SMI-S (Option B) is incorrect: SMI-S (Storage Management Initiative Specification) is a legacy industry standard that is largely deprecated in favor of RESTful interfaces. Pure Storage does not focus on SMI-S for modern third-party tool integration.
Why SYSLOG (Option C) is incorrect: Syslog is excellent for Event Logging (e.g., "User Logged In," "Volume Deleted"), but it is a poor choice for Performance Monitoring. You cannot effectively graph IOPS or bandwidth trends using Syslog streams alone.
質問 # 58
What is the recommended Maximum Transmission Unit (MTU) size for the replication ports on a FlashArray?
正解：C
解説：
Pure Storage strongly recommends an MTU size of 9000 (Jumbo Frames) for replication networks-such as those used for Asynchronous Replication, ActiveCluster, and ActiveDR-as well as for iSCSI and NVMe/TCP data networks.
A 9000-byte MTU significantly reduces protocol overhead and CPU processing load on the storage controllers by allowing a much larger payload of data to be transmitted inside a single network packet. During heavy replication, this drastically increases throughput and maximizes bandwidth efficiency.
Here is why the other options are incorrect:
1500 (B): While 1500 bytes is the standard default MTU for Ethernet and is exactly what Pure Storage recommends for the management ports (vir0), it is not the recommended optimization for high-throughput replication traffic. (Note: If your network cannot support 9000 end-to-end, 1500 must be used to prevent packet fragmentation, but 9000 remains the best-practice recommendation).
4200 (A): This is an arbitrary number and is not a standard network MTU size used in Pure Storage environments.
質問 # 59
RFC2307 enables cross-protocol support for which two protocols?
正解：A
解説：
Understanding RFC2307: RFC2307 is an extension to the LDAP (Lightweight Directory Access Protocol) schema that allows for the storage of Unix-style information (POSIX attributes) within a directory service, most commonly Microsoft Active Directory. These attributes include things like uidNumber (User ID), gidNumber (Group ID), and login shells.
The Cross-Protocol Challenge: In a Unified Storage environment where the same data needs to be accessed by both Windows clients (using the SMB protocol) and Linux/Unix clients (using the NFS protocol), the storage array must be able to map a Windows Security Identifier (SID) to a Unix UID/GID.
How Pure Uses It: When an administrator enables RFC2307 support in Purity//FA File Services, the FlashArray can query Active Directory to retrieve these POSIX attributes. This creates a 1:1 mapping between the Windows user and the Unix identity.
The Benefit: This mapping ensures that a user can create a file via SMB and another user (or the same user on a different system) can access or modify that same file via NFS while maintaining consistent permission enforcement and ownership records. Without this (or a similar mapping service like NIS or local files), cross-protocol access often results in permission "Mapping" errors or files being owned by "nobody."
